How to re-roof yourself. Do-it-yourself roofing of a house. Arrangement of waterproofing and ventilation

A situation often arises when even newly built houses need to be reroofed, not to mention buildings that were erected a long time ago. Such a need may arise due to leaks, sagging, heat loss, etc.
No less often, this service is required simply because you need to replace the old roof with a new one. In any case, the owner is faced with a choice - turn to specialists, or solve the problem on his own.

To perform work, in addition to knowledge of theory and special tools Practical skills will be required, without which it will simply not be possible to successfully carry out all the operations necessary to obtain the result. By entrusting this work to professionals, you ensure a long life for the roof of your home.

Covering the roof of a house

The complex of roof covering works is carried out in several stages, each of which requires the utmost precision in execution.
To do this, it is necessary to have knowledge of the main functions of the roof, namely protective, sound and heat insulation and aesthetic. You also need to have an idea of ​​all the components roofing structure, which is traditionally called “roofing cake” - base, thermal insulation, vapor barrier, roofing material.

All this knowledge is fully possessed by the specialists working in our company “Zvezda Roofing”

Main stages:

• installation of sheathing;
• waterproofing and vapor barrier device;
• roof insulation;
• laying roofing material.

The first three stages are common to all types of work. The fourth has its own specifics depending on the chosen material.

However there are some general rules which must be used when working with any roofing materials:

• Roofing material should be laid from bottom to top (except hipped roofs) with mandatory alignment along the overhang and cornice;
• if the roof slope has a triangular shape, the roofing material is laid from the center on two sides;
• on rectangular slopes, laying can be done both from left to right and from right to left;
• to ensure normal water ingress into the gutters, the roofing material should hang from the sheathing by 5-6 cm;
• If the roofing material is not supplied with special fasteners, screws or nails should be used to install the roofing.

Vehicle owners are interested in safe and comfortable conditions car storage. An important role is played by the roof structure. Problematic situations with the roof negatively affect the thermal insulation of the garage space, its waterproofing protection, and also increase the likelihood of access by intruders. Variety of offered roofing materials puts garage owners at a dead end and makes them think about how to cover a garage roof in order to get a decent result at a minimum level of cost.

Choosing how to cover the garage roof

Specialized stores offer a variety of building materials for roofing projects. They allow you to provide reliable protection garage space from the negative impact of natural factors.

Materials are divided into the following groups:

• rolled materials - roofing felt, linochrome, uniflex, bikrost and others;
• metal sheets of profile section - corrugated sheets, metal tiles, galvanized;
• roofing building materials based on asbestos-cement - slate, euro-slate;
• special bitumen-based coatings - ondulin and others;
• solid and hollow concrete panels, reinforced with steel reinforcement grid.

Each type of roofing material has its own advantages. Buyers are attracted by high performance characteristics, reasonable prices, as well as the ease of doing installation work yourself.

It is important to decide what is better to cover the garage roof, taking into account the following factors:

• reliability of building materials;
• durability of roofing;
• acquisition and transportation costs;
• specifics of installation work;
• maintainability of roofing material;
• self-installation possibilities;
• load on rafter system roofs.

It is important to pay attention to the harmonious combination of the garage floor with the roofing material of the adjacent building. It is easy to equip a detached garage building with an economy class ceiling. Let's consider the characteristics of popular building materials used for roofing activities.

Covering a garage with slate

Wavy or flat slate – traditional material for roofing, made on the basis of asbestos cement. It has a number of advantages:

• long period of operation;
• ease of machining;
• resistance to aggressive environments;
• increased hardness;
• susceptibility to local loads;
• reduced moisture absorption.

Developers are attracted by the possibility of self-installation, accessibility, and acceptable price. One of the advantages of the material is the absence of rain noise in the garage, unlike metal profiles.

Along with the advantages, slate also has weaknesses:

• increased weight of sheets, creating difficulties when lifting material;
• high probability of damage due to impact;
• reduced resistance to significant temperature fluctuations.

Despite the existing disadvantages, slate is preferred, as it has been proven in different conditions exploitation of the material.

Corrugated sheeting and metal tiles for garage floors

The specified roofing materials are made of corrugated steel sheets, coated protective layer zinc

Corrugated sheets and metal tiles are modern roofing materials that have a range of advantages:

• increased strength;
• long service life;
• ease of self-installation;
• wide color palette;
• increased reserve of rigidity.

Profile sheets roofs make it possible to ensure the tightness of the covered space. It’s easy to cover a garage on your own using self-tapping screws. When screwed, they cut special holes in the metal through which the access of moisture into the room is limited thanks to rubber seals. Profile sheets hide uneven surfaces well. However, the material is susceptible to corrosion in areas with damaged paintwork.

Bitumen based tiles

Some garage owners prefer asphalt shingles. It is a multilayer material based on fiberglass impregnated bitumen composition. On outside The bitumen base is coated with basalt chips or mineral granules of various colors. The bottom side is treated with a self-adhesive composition on a polymer-bitumen basis. As a result of heating caused by the influence sun rays, the tiled petals are glued together into a common covering.

Compared to other roofing building materials, bitumen-based shingles have a number of advantages:

• unpretentiousness in operation;
• ease of installation and repair;
• noise insulation properties;
• increased water resistance;
• resistance to microorganisms;
• resistance to chemical reagents;
• reliability and durability;
• resistance to temperature fluctuations.

An important advantage is the low weight of the tiles, as well as the ability to use them on roofs of complex shapes. Main disadvantages:

• the need to arrange a continuous sheathing;
• the possibility of laying the material only on a moisture-resistant slab;
• increased cost and fire hazard.

Covering a garage with tiles not only reliably protects the building from moisture, but also gives it an original look.

Types of roofing structures

When deciding how to cover the roof in the garage, you should take into account the design features of the roof structure. Let's look at the types of roofs and the floor materials recommended for each option.

Roof with one slope

A pitched roof with a slight slope is a budget solution. The design is different:

• simplicity of construction;
• efficiency;
• ease of repair.

The following roofing materials are used:

• metal profile;
• roofing felt;
• galvanization.

Gable roof with slope

The design features of the gable version with a roof slope of more than 18 degrees allow the use of most roofing building materials:

• asbestos-cement slate;
• metal tiles;
• corrugated sheet and galvanization;
• ondulin.

The use of a smooth metal profile capable of absorbing the mass of snow cover will ensure independent snow melting. Rigid corrugated sheeting with an increased margin of safety - optimal solution for cold climatic zones. It is important to reliably insulate the roof so that condensation does not drip onto the car and floor during the cold season. It is easy to insulate the garage floor using modern materials with your own hands.

Mansard roof

Roof structure mansard type allows you to rationally use space and place a recreation room or workshop above the garage.

It is advisable to use as a material:

• metal tiles;
• profiled sheet;
• ondulin.

It is undesirable to use heavy slate or thick metal, which creates significant forces on the rafter beams.

Multi-pitched roof type

A garage with three or four roof slopes is rare. However, wanting to give an original appearance garage building, it is worth choosing a multi-slope roof structure. It is preferable to use metal tiles to cover the garage, which reduces costs and reliably protects the room from precipitation.

General technology for covering a garage roof

For most types of roofing materials, the algorithm for installing a garage floor includes the following work:

1. Construction of a roof truss.
2. Styling waterproofing material.
3. Fixation of the roof.
4. Installation of heat insulator.
5. Attaching the vapor barrier gasket.
6. Carrying out interior finishing.

For collective buildings, the flooring is often made with concrete. Concrete roof It is durable and protected from precipitation by bitumen or roofing felt. The concrete floor is made monolithic or formed from separate reinforced concrete slabs.

At the final stage, you should worry about connecting the electricity. It is not necessary to invite an electrician to lay the wires under the covering. Electrical wiring is easy to install yourself if you follow safety requirements and know the basics of electricity.

The choice of building material for roofing - the main requirements

When deciding on the material for the ceiling, pay attention to its characteristics:

• moisture resistance;
• strength;
• appearance;
• mass;
• price.

When deciding to purchase garage floor material, consult with professional builders or consult a sales consultant in the store.

How to cover a garage roof with euroroofing felt?

Vehicle owners do not always know how to cover a garage roof with roofing material. Carry out the work following the sequence of operations:

1. Clean the surface from resin, oil and dirt.
2. Remove any remnants of the previous coating.
3. Apply hot bitumen to the prepared surface.
4. Place rolled roofing felt on the mastic with an overlap of 15-20 cm.
5. Lay the second layer of roofing material on the bitumen.
6. Remove air inclusions using a special roller.

When performing work, use a blowtorch to melt the polymer layer. Make sure there is a slope for unobstructed drainage of sediment. If necessary, consult with professionals who will tell you how to cover the garage roof with your own hands.

Galvanized metal garage floor

Perform galvanizing installation according to the following algorithm:

1. Lay vapor and waterproofing on the prepared base.
2. Lock securely protective covering stapler.
3. Install 5x5 cm beams and secure to rafter beams self-tapping screws.
4. Nail the sheathing boards at intervals of 50-60 cm.
5. Attach the corrugated sheets to the base with self-tapping screws.

All that remains is to install the ridge and secure the cornice strips.

The use of polycarbonate as a roofing material

For light garage or garage canopy Cellular polycarbonate is suitable. The popularity of the material is due to its high performance characteristics:

• light weight;
• increased strength;
• flexibility;
• transparency;
• durability.

It is not difficult to build a polycarbonate garage cover on your own. It is important to prepare a reliable base for attaching the sheets and firmly fix the material.

Is it necessary to waterproof the roof?

Waterproofing protection is necessary for all types of roofing coverings. It performs the following functions:

• prevents moisture from entering the room;
• ensures unhindered steam escape from the garage.

A membrane made in the form of elastic sheets up to 3 millimeters thick is used as a waterproofing material.

Thinking about building a permanent garage or a garage on screw piles, decide how to cover the garage roof. It is useful to learn how to make a reliable foundation for a garage with your own hands, and also to figure out how to make a floor in a garage. A high-quality garage floor will reliably protect the room from moisture and dampness. In such a garage it is worth allocating space for storing the grown crops. How to do it is described in the corresponding article.

Conclusion

When planning to cover a garage, be responsible when choosing roofing material. You should not give preference to cheap building materials produced by unverified manufacturers. When performing work, follow the technology. If you have no experience, use the services of professionals.

When planning a house construction Special attention paid to the choice of roofing. I want it to be distinguished by quality, durability and be affordable. It's worth paying attention to. The variety of roofing materials can baffle anyone. In such situations, a thorough analysis of the advantages and disadvantages of each type of roofing material belonging to the economy class will help you make a choice. We will talk about how much it costs to re-roof a country house or a private house and what material is best to do it with in this article.

Metal tiles - the main material

When the question arises of how to cover the roof of a private house, the answer is most often metal tiles. Yours wide use this material received due to its obvious advantages.

Advantages of metal tiles:

• accessibility, both in price and availability of material in stores;
• simplicity and ease of installation;
• environmental friendliness - due to the fact that metal tiles are made of steel;
• long service life - more than 20 years;
• large selection of colors.

The disadvantages of this roofing material are:

• noisiness - during rain, the sounds of drops hitting the roof will be clearly audible;
• windage;
• the need to additionally insulate and soundproof the roof;
• susceptibility to corrosion;
• large waste residue when roofing complex roofs;
• minimum rental drawings.

When choosing metal tiles, you need to calculate not only how much it costs to re-roof a private house based on the cost of the material and roofing works per square meter, but also the price of additional elements. It often happens that metal tiles are sold at a reduced price, and then, when it comes to purchasing additional elements, they turn out to be prohibitively expensive.

The thickness of the steel and the amount of zinc contained are important indicators of the quality of metal tiles. The higher these indicators, the better. By purchasing metal tiles from trusted manufacturers, you can protect yourself from unnecessary hassle with poorly made material.

The cost of a metal roof depends on many factors:

• cost of material ($6-13 per sq.m.);
• cost of installation work (50-100% of the cost of the material);
• cost of additional work and materials;
• complexity of the design.

The roof area depends little on the square footage of the house, since the building can be two or three stories high, which means the size of the roof will depend only on the area of ​​the floors and their own design features.

For a more accurate cost calculation, you should use our calculator, or roofs.

On average, a metal tile roof will cost:

• For small house(about 100 sq. m.) – close to $1000;
• for a medium-sized house (about 200 sq. m.) – $1200-2000;
• For big house(about 300 sq. m.) – $2000-3000.

Soft tiles for the roof of a house

Soft tiles are often chosen for complex structural roofs.

The main advantages of this material include:

• ease of installation;
• a huge variety of material colors;
• minimum waste during installation;
• environmental friendliness;
• noiselessness;
• durability (more than 30 years of operation);
• minimizing risks when purchasing, due to the complexity of manufacturing the material and the impossibility of counterfeiting it.

Flaws soft tiles This:

• frequent breakage of material due to strong winds;
• the need to make a continuous base - a common sheathing;
• impossibility of building a “living” roof.

Price of soft tiles

Considering that the cost of soft tiles is $7-17 per sq.m., and roofing work will cost $6-40 per sq.m., for a roof made of soft tiles you will need:

• for a small house (about 100 sq. m.) – $1000-4000;
• for a medium-sized house (about 200 sq. m.) – $1200-8000;
• for a large house (about 300 sq. m.) – $1800-12000.

This material also requires a careful approach to the selection of additional elements and assessment of their cost.

Corrugated bitumen sheets

Corrugated bitumen sheets are most often the choice of people constructing utility buildings or simple summer houses.

Among the advantages of this material, the following are highlighted:

• low cost;
• ease of installation - roofing can be done even without special skills;
• ease of transportation;
• noiselessness;
• the possibility of using lightweight, inexpensive sheathing;
• unusual shades of material;
• environmental friendliness;
• long service life (at least 15 years);
• low cost of additional elements;
• market transparency – no risk of buying a fake.

Disadvantages of corrugated bitumen sheets:

• limited design solutions;
• possibility of leaks;
• possibility of material sagging.

When installing this material, using special nails with specific heads (20 nails per sheet) will extend the service life of the roof.

Cost of corrugated bitumen sheets

The cost of the material ranges from $9-12 per sheet; roofing work with bitumen sheets costs $4-5. A complete roof made of corrugated bitumen sheets will cost approximately:

• for a small house (about 100 sq. m.) – $800;
• for a medium-sized house (about 200 sq. m.) – $1000;
• for a large house (about 300 sq. m.) – $1200.

Keramoplast

Keramoplast is a composite material made from organic raw materials and plastic granules.

The main advantages of keramoplast:

• high rigidity;
• noiselessness;
• Absolutely environmentally friendly.

Among the disadvantages of ceramoplast, the following are especially common:

• poor tolerance to temperature changes;
• fragility;
• difficulty of transportation.

• for a small house (about 100 sq. m.) – $800-1200;
• for a medium-sized house (about 200 sq. m.) – $1200-6000;
• for a large house (about 300 sq. m.) – $1500-8000.

Composite metal tiles

Composite metal tiles act as a little-used material, since few people know about its existence. Its base is a metal sheet, and the surface is made of stone granulate.

Among the advantages of this material are:

• wide selection of colors and shapes;
• high anti-corrosion ability;
• noiselessness;
• durability (more than 50 years of service);
• reliability.

In addition, this roofing material includes all the advantages of metal tiles and soft roofing.

The downside is:

• complexity of installation;
• relatively high cost of material and additional components.

The cost of such a roof is in the following price range:

• for a small house (about 100 sq. m.) – $7,000-20,000;
• for a medium-sized house (about 200 sq. m.) – $20,000-50,000;
• for a large house (about 300 sq. m.) – $40,000-60,000.

Analysis of the given data shows that the roof is made of wavy bitumen coatings will cost the least, but this material also has the shortest service life, while the most expensive material - composite metal tiles - has the greatest durability among all materials and the fewest disadvantages.

How much does a roof cost: reviews from the forum

Igor M.

I was going to reconstruct the dacha. My house is not big, just 6x9. I want to dismantle the old roof, raise the floor by a meter and install a new one made of metal tiles. The roof is the simplest gable. I started asking about prices. They quoted me a turnkey price of 450 UAH per m2. This is just work without materials.

I am disappointed. You only need to pay 130 UAH per m2 for the metal tile itself, plus rafter part, insulation, etc. It's getting a bit expensive. But I started asking further, they said that the maximum price is now 200 UAH per m2. I talked to the foreman. He promised to do it for 300 m2. We calculated the materials and the work came out to 48,000 UAH, approximately $2,000. We agreed that we would begin with the first rays of the spring sun. I put the money aside and am waiting.

Sergey B.

I decided to remodel my parents' house a little. I did the insulation. I decided to cover the roof with metal tiles. I don't need to redo anything much. Me two years ago major renovation I did the roof, just remove the slate and replace it with metal tiles.

I didn’t think long and called the specialists who had already worked for me. They say 300 rubles ($5) per square, and we will change everything. Indeed, I brought the materials, the guys came and did everything efficiently. In Moscow, I would hardly invest in such a budget, except that in Ukraine their construction services are cheaper.

Alexey K.
I live in Russia, I’m from Ukraine. It so happened that in two years we had to replace the roofs on houses in two different countries. First with his wife’s parents, and then with his own. And you know me, I was confused by some of the pricing positions. When I was replacing the roof on my mother-in-law’s house, it was all for the first time. I thought for a long time about what material to choose and how to make it. Although I am a busy person, it was still interesting. How people make it and from what. Therefore, I delved into both the cost of materials and the quality of work.

On next year I came to my parents to visit. I looked at the old house and decided that it needed to be updated. I didn't have any questions about the roof. I already knew clearly what and how I needed. In both cases it is a house of approximately 200 m2, under a slate gable roof with an attic. Having experience, I immediately started looking for a contractor who would do all the work on a turnkey basis.

I'm still on vacation, so I left control behind me. I was lucky with the builders and the first and second time I came across experts in their field who knew how to do the job well and quickly. The roof went up very quickly. But being forced into construction, or rather supervision, I compiled the so-called international price list for roofing work. Let's not take the materials, they are almost similar, in dollar terms.

Turnkey roofing production

So let's get straight to the point:
1. Dismantling of the old roof – 250 rubles/m2; or 10 UAH/m2.
2. Manufacturing cold roof turnkey from metal tiles, depending on the complexity of installing rafters, installing sheathing, installing waterproofing, fastening counter battens, the metal tile itself, ridges, wind strips, valleys - 1200 - 1300 rubles/m2; or 130 – 160 UAH/m2.
3. Insulation – 280 rub./m2; or 40 UAH/m2.
4. Installation of floor beams – 150 - 200 rubles/linear meter; or 35 UAH/ linear meter
5. Installation of gutters, depending on the floor - 245 - 420 rubles / linear meter; or 40-55 UAH/ linear meter
6. Sheathing of overhangs - 550 – 600 rub./linear meter; or 70-90 UAH/linear meter
7. Arrangement of gables with facade materials, such as siding or clapboard - 350 - 400 rubles/m2; or 60 – 70 UAH/m2.
8. Installation of a roof window – 3000 - 4000 rubles/piece; or 600 - 1150 UAH/piece.
9. Installation of rough walls and ceiling – 70 – 80 rub./m2; or 35 UAH/m2.

In both cases, measurements were carried out free of charge, because subsequently, I took the material and ordered the work itself. Although initially everyone said that the service was paid. Metal tiles and related materials were delivered free of charge, for the same reason.
After analyzing the metal tile roof, I decided to look at the roof from different materials. I will indicate the prices for cold roof installation work when installing them on a turnkey basis:
Bitumen shingles – 1800 - 2100 rub./m2; or 160 – 220 UAH/m2.
Natural tiles - 1100 - 2000 rub./m2; or 300 – 350 UAH/m2.
Roofing corrugated sheeting – 800 – 1000 rub./m2; or 150 - 200 UAH/m2.
Composite tiles – 1100 - 2000 rub./m2; or 200 - 250 UAH/m2.
Euroslate, Ondulin, Aqualine – 800 – 1000 rub./m2; or 150 - 200 UAH/m2.
Tariffs for insulation, installation drainage system and other works do not differ from those used when constructing a metal roof.

Thus, we can conclude that the choice of roofing material directly depends on individual preferences, phrasers, purpose and design features of the building, so it is impossible to give an unambiguous answer to the question of what is better and cheaper to re-roof. Each material has its own pros and cons, so it is necessary to individual choice, based on the above data.

   Guys, by and large, what's the point of asking in the comments how much work on your roof will cost? Ask a question either to several contractors at once and compare, or if you are making an estimate, you can contact the supplier directly. Serious companies will calculate everything for you for free, at the same time you can talk more with the manager, and maybe you’ll even get yourself a discount. I bought metal tiles from Grandline for my two-slope roof (gazebo + canopy). Everything was calculated, delivered, neatly packaged, I don’t know any troubles for the third year. Who needs it, website grandline.ru

   please tell me the approximate cost of the work. Hangar in the Moscow region. Sandwich panel roof. The work consists of the following unwinding. We lift the top sheet from the sandwich panel into a brazen position. We seal the joints with sealant tape. screw it back. Our building materials. The total length of the joints is 400 meters. Some part of the roof is generally not screwed in, so we screw it in about 50 meters, thanks in advance.

4. Vladimir

   how much does it cost to cover a metal tile roof with a soft roof - 183 sq.m.

5. Georgiy

   If you can roughly calculate the cost of working with your materials:
   1. Remove the galvanized iron roofing statue.
   2. Insulate with 150 mm basalt (or other material) slabs. with hydro and vapor barrier.
   3. Cover the roof with metal tiles.
   4. Insulate the gables over the lining (suggest an insulation option).
   The roof is gable, area 120 sq. m.. Gables 18 sq. m. m. with windows of 1.8 sq. m. m.
   I can send you a drawing of the roof and gables to your email.
   Best regards, Georgiy.

The first type is built with a slope not exceeding 7 percent. Such roofs are multifunctional, but require a drainage system and moisture permeability. Technologies make it possible to construct a flat surface from transparent materials.

TO pitched roofs are one and the same gable structures: hip (4-pitched), half-hip, attic (allow you to use the attic as a full-fledged room) and multi-gable.

In addition to these designs, spherical and dome options. The combination of several types of roofing is called a combined roof.

We select the roofing material by type, taking into account the following parameters:

• durability – the ability of a material to retain its properties under repeated changes in external conditions.
• price (sum of material and fasteners);
• cost of installation and auxiliary materials;
• appearance;
• safety.

For flat roof

Polymer mastic - new life for outdated technology

The material replaced bitumen (resin), which was preheated and applied to the roof surface. The disadvantage of the method was considered to be harmful to roofers and fragility. Modern “hot” mastics are designed for waterproofing. Mastic, which, unlike bitumen, is sold in finished form, is applied to the roof with a simple roller. The surface is cleaned of dust before application. The material cannot be used if there are cracks.

Advantages:

• low cost;
• low labor intensity;
• operational repair.

Flaws:

• requires surface preparation;
• fragility;
• high heat losses.

The price per square meter with installation is 2 US dollars. Service life – 3 years.

Self-leveling roofing

The principle is similar to bitumen mastic. The material is liquid and includes oligomers. The composition is applied in layers to a cleaned surface of concrete, metal or bitumen. When plasticized, it forms a continuous waterproof film.

Advantages:

• exploited surface;
• durability;
• resistance to temperature changes over a wide range;
• quickly installed;
• seamless;
• fireproof;
• harmless.

Flaws:

• requires an ideal surface;
• with a slope above 2.5°, reinforcement is necessary;
• the price depends on the number of layers.

Minimum bulk cost polymer mastic– 5 $. Service life – 15 years.

Flat membrane covering

PVC, TPO and EPDM membranes are used for roofing. Polyvinyl chloride material is not safe for humans, but is resistant to ultraviolet radiation and open fire. Rubber membranes (EPDM) are harmless and durable (reinforced with polyester mesh). TPO is identical in properties to EPDM, but contains reinforced olefins.

Membranes are installed by fastening along the perimeter of the roof. Apply on flat surfaces, for the roof of large buildings.

Advantages:

• water resistance
• large coverage area without seams
• work is carried out at any time of the year
• low labor intensity during installation
• does not require repair
• not susceptible to mechanical stress
• durable

Flaws:

• foundation preparation required
• instability to solvents and oils based on organic elements

The guaranteed service life of the membrane is 50 years. The cost per square meter excluding installation is $6. Installation is calculated depending on the complexity and area of ​​the roof. Price from $3 per sq.m.

Roll welding material

The design replaced the traditional roofing felt. The material is commonly called glass insulation, and sometimes waterproofing. Produced in rolls, the basis of which is fiberglass, fiberglass or polyester. The base is coated with modified bitumen sprinkled with mica, quartz sand or shale. Installed on roofs with a slope of more than 10°. Mounted on a solid base on top of insulation and a waterproofing layer. The rolls are rolled out over the surface, forming a continuous cover. The material is overlapped. The joints are glued by heating the bitumen layer.

Advantages:

• durability
• does not require maintenance;
• fire resistance, moisture resistance, sound insulation;
• safety for humans;
• light;
• low cost;

Flaws:

• the material requires special storage before installation (rolls are installed in a vertical position and do not allow interaction with heating devices);
• no possibility of installation on flat roofs slope less than 10°;
• required Additional materials for substrate;
• the roof is not in use;
• no resistance to high ambient temperatures.

The cost per square meter is $2. Installation – $2. Service life – 50 years.

Types of material for pitched roofs

Corrugated sheet

Installation does not require a solid base, which is made in the form of a sheathing made of profiled pipe or wooden slats. Installation is allowed on slopes greater than 10°. The sheets are installed overlapping and secured with screws with seals. With a slope of up to 20°, the joint is filled with sealants.

Advantages:

• ease of installation;
• high bending strength;
• durability;

Flaws:

• Soundproofing required.

Price per meter square cover– 3-6$. Service life – 50 years.

Buy the highest quality Bulat corrugated sheeting, which has a 25-year guarantee.

Sandwich panels

This is a multi-layer material. The design consists of 3 layers: 2 outer layers - profiled sheet, inner layer - polymer insulation (foam plastic). The layers are connected to each other using glue or the cavity is filled with hot foamed polymer. The finished structure forms a monolithic rigid material.

The sandwich has low thermal conductivity and high strength characteristics and does not require the preparation of a special frame. The service life of the material reaches 30 years. The price per square meter is $25 and varies depending on the thickness of the material. Installation cost is $3.

Seamless sheet metal roofing

Suitable for pitched roofs. The material consists of flat sheets of metal that are fastened together by folding (a lock formed by a special bend). Folds can be single or double. Standing seams are formed along the roof slope, and recumbent ones are formed across them. Roofs are made of ordinary sheet steel, galvanized or steel coated with polymer protection. Copper and aluminum sheets are rarely used.

Seam roofing is suitable for roofs with a slope greater than 14°. It is laid on a wooden sheathing, on which an anti-condensation coating is installed. Install the sheets in 2 stages. The stripes (patterns) are formed first equal to length stingray Then the paintings are lifted to the roof, where they are connected to each other by the side edges. Folding is performed with a special tool.

Decorative and natural materials for roofing

Slate

This is a natural stone that is manually shaped for roofing. Installation is carried out by joining the tiles overlapping using locks (grooves). Lathing is required for installation. The disadvantage is the large weight, reaching 25 kg per square meter, and the price. The service life of the roof is 100 years.

Straw and reeds

Plant stems – popular natural material for covering luxury buildings. For roofing, heather, reeds, reeds and any plants with long hollow stems are used. For example, a reed covering is created in a layer of 30 cm, the dry weight of which reaches 40 kg. The roof angle must be at least 45°.

The service life of a plant roof reaches 50 years. The price including installation work is $100 per square meter.

Tree

Wooden roofs treated with modern chemicals last up to 50 years. The material is not subject to cracking, rotting and delamination. Does not promote reproduction biological species. Plank, chip and shingle types are common. The material prepared for installation is expensive. Price 1 sq.m. – $50, and the installation cost is $200.

Not everyone decides to cover an old roof on their own, considering this work to be complex and difficult. Of course, these people are partly right. However, there is a noticeable desire to preserve family budget forces many to “cross the Rubicon.” To proudly declare that I rebuilt this roof with my own hands, you need to study the instructions I offer, familiarize yourself with the specifications of the materials used and select the necessary reconstruction option.

What elements does the roof of a house consist of?

The roof is general concept a structure that covers the space above your head from precipitation, sunlight and other external influences. In private house construction, a roof means a multi-layer structure located on special mounting units - beams, joists, which, in turn, are attached to the walls and ceilings of the house. A roof consisting of a number of layers various materials, got the name roofing pie.

The overall roof design and the cost of constructing or repairing it largely depend on the roofing materials that will be used. At the same time, regardless of their characteristics, general scheme roofing pie consists of the following elements (listed from bottom to top):

1. Rafters are the supporting beams on which the entire structure rests. Depending on the roof configuration, they can form one or more slopes. The most popular roof option is a gable roof. In it, with their lower ends, the rafters rest on the mauerlat - a wooden frame around the perimeter of the wall, and top ends form the vertices of a triangle.
2. Vapor barrier. It is needed so that moisture from interior spaces did not penetrate into the insulation. It is stuffed from the inside to the rafters. It doesn’t matter what kind of room is under the roof - cold attic or a heated attic - due to the temperature difference, condensation always forms inside. A layer of vapor barrier film prevents it from getting into the insulation and other components of the roofing cake.
3. Insulation. Even if there is no living space under the roof, but only a cold attic, insulation is still needed, since up to one fifth of the heat is lost through interfloor covering and roofing. Gained great popularity as roofing insulation mineral wool. It is environmentally friendly, non-flammable, and lightweight. One thing is bad: it loses its properties when exposed to moisture, which is why it must be covered with membranes on both sides. Mineral wool slabs are very convenient to lay between the rafters.
4. Waterproofing also acts as a membrane, only, unlike the bottom film, this material allows steam molecules to pass through, but water will not pass through it. The order “waterproofing from above, and vapor barrier from inside the room” is very important, otherwise the insulation will get wet over time.
5. Counter-lattice. These are slats that are packed along the rafters. They have a dual function: they ensure a tight fit of the waterproofing to the rafters, and also provide ventilation gap between the membrane and the final roofing covering. When using corrugated sheeting, seam roofing, metal tiles, etc., condensation is formed, which must evaporate when air passes through the ventilation gap.
6. Lathing. It consists of slats, boards or a solid covering, but already packed across the rafters. Installation is carried out directly on it finishing coating. In the case of using rigid materials, sparse lathing is used. Soft roof requires the arrangement of a solid substrate, which is sheet plywood or OSB boards.
7. Finish coating. It is called so because it is laid last. It will take on all environmental influences: precipitation, sun rays, wind, so its choice should be approached responsibly.

Selecting material for roof replacement

The owner of the house himself chooses what to cover the roof with, based on his own taste. However, it is worth taking into account the technological features of installation. At self-installation There are “easy” and “problematic” materials. For example, ceramic tiles requires skill in installation, and a solid foundation is needed, so it will not be easy for a beginner to properly install a roof from it. If the house has a roof of complex configuration with rounded elements, then it is foolish to try to cover it with slate or corrugated sheeting - for this they use bitumen shingles. However, each material has its own characteristic features.

Properties of metal tiles

Metal tiles are one of the most convenient roofing materials for DIY installation. Its weight is not very large, the sheets have acceptable sizes and are convenient for installation. The wavy surface of metal tiles requires relatively frequent lathing to prevent the steel from bending.

The sheets begin to stack from bottom to top. Adjacent surfaces are mounted overlapping the width of one wave - this avoids the penetration of moisture and wind under the roof. The metal tiles are attached to the sheathing using galvanized self-tapping screws with a double washer - steel and neoprene, which serves to seal the hole. This makes the fasteners of metal tiles similar to corrugated sheets. The durability and decorative appeal of the coating is ensured by the coloring layer and multi-layer coating.

Features of corrugated sheets

Corrugated sheeting is the closest “relative” of metal tiles. The difference is in shape: corrugated sheets are produced by cold rolling through rollers, so rectangular waves alternate with grooves. For the roof, take corrugated sheeting with a wave height of at least 20 mm, which is appropriately marked.

The design turns out to be durable, but it must be handled carefully - a scratch on the surface can create a source of corrosion, and after some time the sheet will have to be replaced.

Battles between supporters rage online different schemes corrugated sheet fastenings. Some argue that you need to tighten the screws between the waves, others - that into the wave. In fact, both methods have their place, each has its own disadvantages. The screws between the waves are in the path of flowing water, which means that the risk of leaks increases if the neoprene washer wears out or is installed incorrectly. To twist into a wave, you need a longer self-tapping screw, and if the tightening force is exceeded, the steel may become deformed.

Pros and cons of soft tiles

Soft or bituminous shingles are fiberglass on which a resinous adhesive coating is applied, and on top of one side there is granulate - small particles hard material, which increase wear resistance. The soft tile pieces are jagged to create the effect of real tiles.

Installation bitumen shingles is carried out on a solid base made of plywood or OSB boards. An underlay carpet is laid on top of it, and then the shingles are laid overlapping. They are fixed with nails with wide heads. Thanks to the bitumen base, the tiles additionally stick to the base when exposed to sunlight.

The advantages of the material are complete waterproofness and resistance to rotting or corrosion. The soft roof does not rattle in the rain. It has only one disadvantage - high cost, since creating a continuous base with an underlay carpet greatly increases the price of this roofing option. The experience of my Canadian friends suggests that over time outer sheets are torn off by the wind, so they have to be replaced with others.

Characteristics of ondulin

Soft slate, bitumen slate - this is also what this material is called. It is completely identical to slate in shape, but in essence the material is completely different. Its base is cardboard or fiberglass, which is impregnated with bitumen and pressed at high temperature. This is how the leaf acquires a characteristic wavy surface. Like slate, ondulin is attached to nails with wide heads and washers. The lathing for ondulin does not have to be continuous, but frequent - with a pitch of transverse slats of at least 40 cm.

Good old roofing felt

Ruberoid became famous much earlier than other modern roofing materials. It is based on cardboard impregnated with bitumen and sprinkled with stone granulate to preserve properties and protect against external influence. Today, roofing felt has been improved: fiberglass is used as a base, which increases strength, including tensile strength. Manufacturers, in order to announce innovations, call such material euroroofing felt or glass insulation.

A roll of roofing felt rolls out over the surface and heats up. gas burner with a long nozzle or blowtorch. The bitumen is melted and glued to the continuous sheathing. The roll is rolled out along the ridge, starting from the bottom strip. If the roof is very steep, rolling is carried out across the ridge, additionally coating the joints with bitumen.

Familiar slate

Another old-timer among roofing materials has been familiar to us all since Soviet times. It hasn't changed much since then. It's still a cheap, hard, heavy corrugated material that doesn't have any tensile properties. The advantage is the ability to reroof with a small budget and lack of experience as a roofer.

Seam roofing

This option is one of the most durable, reliable and at the same time expensive. Seam roofing is metal sheets that are laid on the sheathing and fastened into a special lock - a seam. In this case, the edges of adjacent sheets are bent in such a way that completely eliminates the penetration of water. The roofs of old European houses, which are hundreds of years old, are either tiled or seam.

How much does it cost to re-roof

Of course, before you start re-roofing, you need to resolve one of the main questions that arises for the owner - how much will it cost to replace a worn-out roof.

The approximate cost will be indicated taking into account the rework of all roofing components, except for the rafters themselves. That is, you will need to replace the insulation, vapor and waterproofing membranes, the sheathing that could rot, and the coating itself. If you estimate the total cost of a house 10 by 10 m s gable roof with an angle of 35 degrees along the slope, then the total area will be 120 square meters. m. The list of estimated costs will be:

Dismantling the old roof. The price in different regions of Russia may vary, the average value at 2019 prices will be about 270 rubles. per sq. m. That is, the entire roof will be removed for 32.5 thousand.

Insulation. Mineral wool slabs cost about 2,100 rubles. per square, plus installation will cost 100 rubles. The total for the whole house is 265 thousand rubles.

Flooring waterproofing membrane will cost 160 rubles per square, and about 90 more will be required for the work itself. In the amount of 30,000 rubles. A new counter-lattice will cost about 30 thousand rubles.

Metal tiles (as a medium-cost and highly reliable material) will require an investment of about 420 rubles. per sq. m, and even 300 rubles. for work. Result: 86,400 rub. The total cost of roofing work and materials will thus be about 450,000 rubles (with a small reserve for overruns and unforeseen circumstances).

Work before roof renovation

If a decision was made to block old roof, then the work must follow a specific plan to avoid damage to the surviving coating, cost overruns and compliance with safety regulations.

Removing the topcoat. Usually this is enough hand tools, but you can also use electric. Roofing nails are removed with a nail puller through the backing. The screws are unscrewed with a screwdriver. Flexible roof you will have to tear it off, prying it with a spatula or crowbar down to the solid base.

After dismantling the covering, a thorough visual inspection of the membranes, insulation and rafters is carried out. Wooden parts must not be rotten or moldy. They look for traces of moisture on the rafters. The membranes are inspected for damage to integrity, which could lead to the insulation getting wet. If punctures and cuts are found, remove the membrane, take out the insulation and change the area that was wet.

A rotten section of rafters or sheathing must be replaced. This is easy to do one at a time, as long as all other elements securely hold the structure in the desired position. After replacement, the usable insulation is put back in place, the damaged one is replaced with fresh one. Rolls of waterproofing are rolled out again along the ridge, starting from the bottom, the joints are sealed with tape and pressed against the rafters with sheathing slats. Thus, covering an old roof comes down to replacing damaged elements with new ones.

Laying a new roof over an old one with your own hands: simple and inexpensive

If your home has an old slate roof that is leaking, fragments are split or dislodged, it is not at all necessary to dismantle the entire roof and rebuild it completely. More economical and easier to install new roof on top of the old one.

You won't need many tools: a hammer, a wood saw, a screwdriver. As a finishing coating, we will consider ondulin, including the ridge corner. You will also need timber for additional sheathing, screws and nails:
