Owners of cars and other types of transport most often experience this kind of difficulty in the spring. This is due to the constant melting of snow and ice on the roof of the building. A well-made roof will help prevent or eliminate existing problems, keep the room dry without leaks for a long time.
In this article, we will look in more detail at what is the best way to cover a garage roof, as well as what you should pay attention to when choosing materials.
Our expert’s opinion: what is the best way to cover a roof in a private house and an overview of the advantages of each option
The basic function of a garage building is to protect a car, motorcycle, bicycle and other vehicles from external factors. It is clear that snow, rain, hail, and wind have an extremely negative impact on metal products and structures, accelerating corrosion processes. As a result, the impact of weather will also have an additional negative impact on the appearance of the transport. Therefore, during construction, care must be taken to ensure that the garage roof is of high quality, without allowing any kind of imperfections.
Ondulin - from 250 rub./sq.m.
For roof installations, many homeowners prefer Ondulin, an environmentally friendly, durable, aesthetically attractive material. It has, first of all, high quality coating, long service life, and a rich color palette. Ondulin is easy to install; even a beginner can handle the installation process, following the manufacturer's instructions. The kit contains all the necessary components; no special tools are required for work. The light weight of the material makes the work much easier.
Residents of any region of the Russian Federation can cover their garage roof with Ondulin, since the material is resistant to high and low temperatures and does not change its original characteristics.
The advantages of this roofing material include resistance to the formation of fungus and rust. Ondulin plates are durable and can handle heavy loads of up to 900 kilograms per square meter.
The disadvantages of this type of roofing include its flammability. But it is worth keeping in mind that Ondulin is not prone to spontaneous combustion.

Liquid roof
So, we continue to understand the question of how to cover the garage. And we move on to an amazing roofing material called “liquid rubber”. Essentially, it is a mastic that is applied in liquid form to a flat roof, and it polymerizes in air. The coating turns out to be very durable, but elastic, that is, it resembles rubber, hence the name.
Liquid roofing is divided into two groups:
- bitumen;
- polymer-bitumen.
The first one will last 15 years, the second 25. Their application technology is the same - using a spray bottle. The first group includes mastic brands: “Elomast”, “Gekopren”, BLEM-20 and others. The second is “Polykrov” with different fillings, for example, butyl rubber mastic or chlorosulfonate polyethylene.

Ceramic tiles - from 1200 rub./sq.m
This material is made from clay and other components. The coating does not corrode and withstands high and low temperatures without collapsing or changing its characteristics. When transporting the product, do not forget about its fragility and be careful.
The disadvantages of ceramic tiles include:
- high price;
- heavy weight.
You won’t be able to save on installing a garage roof using this coating.
What technology is used for coating?
Installing a roof on a garage is easier than on a residential building; you just have to decide in advance on the technology for installing a single-pitch or gable structure. If you choose a shed roof, you need to build a frame supported by the top frame. The steps between the rafter supports can not be calculated; this parameter will be indicated by the dimensions of the frame surfaces. The construction process occurs sequentially:
- cut the boards into parts, their number is the same as the racks;
- install beams and secure them with metal corners;
- check the flatness of the planes horizontally and vertically;
- nail the side board to size;
- remove excess;
- tie the ends;
- rafter legs are placed on the side walls;
- align the edges, install the wind board;
- build the sheathing;
- attach waterproofing;
- lay the covering material.
After installing the frame with its elements, they begin to cover the roof. They start with laying thermal insulation layers and pouring waterproofing. Completes the process, decoration and finishing layer. The formation of work depends on the complexity of the structure; it is important to develop and record their sequence so as not to miss important operational moments when installing the coating material.
Attention! When the old roof is to be covered, you need to dismantle it and check the serviceability and integrity of the frame elements. It may be necessary to replace unusable parts, install new thermal insulation layers, and then install the finishing coating.
Let's say the owner decided to use galvanized steel for a sloping roof, due to the cheapness of the material and the ability to cover the garage on his own. He installs the rafters and takes the timber for the sheathing. Do not forget that the smaller the angle of inclination, the greater the load from snow.
Corrugated sheeting is steel stamped according to the profile. The roofer, if necessary, cuts the sheets to the required sizes with the expectation that the installation will overlap the cells. The first plate is aligned along the edge and secured with self-tapping screws.
Corrugated roofing - from 350 rubles/sq.m
Sheets made of galvanized steel can be trapezoidal or wave-shaped. The advantages of this material are:
- ease of installation;
- variety of color palette;
- long service life.
If finances allow, you can safely cover the garage roof with corrugated sheeting .
The material also has disadvantages that should be taken into account. These include:
- tendency to corrosion processes when the protective layer is damaged;
- the need for additional elements during the installation process (additional costs).
Garage plan
Any building is erected according to a plan developed in architecture, a building design, which includes documentation indicating all construction parameters. The document consists of drawings, diagrams with the location of internal and external structural elements. The project includes the following section:
- architectural - with a description of general information, roof plan, payroll statements;
- constructive - with design drawings for the foundation, supporting structures and rafter system are marked, indicating the amount of consumable building materials.
For a garage, it is enough to develop a preliminary design showing the facade and the layout of the roofing pie.
If we consider a classic gable roof, then according to the drawing we can make calculations based on materials and distribute the loads. At this stage of the design it is necessary to note the definition:
- the width of the Mauerlat, it is laid around the perimeter;
- cornice projection;
- rafter location;
- distances between steps;
- tilt angle based on the selected material.
It is important to consider:
- elements fastening points;
- roof area according to plan with drainage system;
- length and width of the slope;
- diagram with the location of the rafters;
- trusses, beams, all roofing elements located on the drawing;
- rafter installation technology.
If corrugated sheeting is chosen for covering, measure the dimensions of the sheet, the number of plates that will fit in one row.
In the plan, each part of the building is developed separately. This document helps suppliers; they select the necessary materials from the list.
The plan shows the roof projection along the horizontal plane and the actual parameters of the slopes. If the seller is given a detailed specification drawing like this with all the details, he will provide a complete installation kit.
The document is developed by the design organization; if the construction is standard, you can not order a new calculation, but use a ready-made project, modifying the diagrams and calculations to suit your needs.
Everything must be done with meticulous precision. Construction does not tolerate mistakes; they can result in disaster and material damage.
Even a schoolchild can calculate the area. It is enough to multiply the width by the height of the slope. But before ordering a design, the developer must know:
- how much he can spend on arranging the roof, so as not to be surprised by unforeseen expenses; the amount is planned with a reserve;
- type of garage, will it be an extension or a separate structure;
- brand of coating material.
According to legislative standards, projects for garages, like outbuildings, must be coordinated with the regulatory service.
Slate - from 120 rub./sq.m.
Another material that can be used for arranging a garage roof is slate. First of all, we are attracted by its low cost, maintainability, ease of installation, and fire resistance. On a hot day, the slate will not heat up. It is also not susceptible to corrosion.
Among the disadvantages of the material:
- heavy weight;
- fragility (must be taken into account during transportation).

DESIGN
Ruberoid - from 30 rub./sq.m.
to cover the garage roof with roofing felt . The material is sold in rolls, impregnated with bitumen, and covered with a special coating (coarse-grained). This coating is suitable for flat roofs. With proper use, the roof will last a long period of time without causing any complaints.
The roll roofing material of the new generation is considered to be the product of TechnoNIKOL Corporation. A wide range of coatings allows the consumer to choose the most optimal option that meets the stated requirements and architectural features of the building. If you select the right material, covering your garage roof with TechnoNIKOL will be the right decision.
When installing a roof with a slight slope, it is worth using a material such as bicrost, which combines high quality and reasonable cost. Bikrost can be used to cover a garage roof that has a slight slope. The coating will protect the building from moisture and can be used for repairs on an old roof.
Garage roof options
Common roofing options when constructing a garage building are as follows:
- single slope;
- multi-slope;
- gable roof.
Shed roof
A pitched roof is an easy option to implement and will be a good choice for newbie developers. A shed roof is a covering with one slope, which rests on the walls of a building with different heights. The tilt angle itself reaches 60 degrees. The exact value of the slope will be known based on the coating material, the climate characteristics of your region, and the wind rose.
If there is no need to build a garage with an attic, then a roof with one slope would be an excellent option. The roofing material itself is placed on wooden rafters, and the height of the difference can be calculated using a mathematical formula. H = D x tan a.
The parameter “a” is determined using the Bradis table, and the value “D” will be the width of the garage structure.
The rafters, due to the fact that they are wooden materials, must be treated with preparations with antiseptic properties. The treatment will protect the wood from damage by microorganisms.
As a recommendation! To improve fire safety, agents with fire retardant properties are used as an additional treatment.
The option of constructing a roof with one slope is regularly used in the construction of garage buildings made of concrete.
Gable roof
If the garage is designed with an attic, then in this option the choice is a gable roof.
Often, the roof structure has a triangular appearance. The rafters rest on the walls and are connected to each other at the desired angle. In this case, an additional support is erected at the upper point connecting them. We calculate the height of the roof ridge H and the value C (length of rafter legs) according to mathematical formulas:
H = 0.5 x H (Z:2), where Z is the slope index.
C = 0.5 x H/sin (Z:2).
If the roof is planned with equal lengths (equilateral), then to determine the required indicators we use the Pythagorean theorem.
The multi-slope roofing option is used quite rarely, due to the complexity of its implementation. In this case, turn to specialists. If you plan to cover the roof yourself with your own hands, then the best option is to choose a pitched roof.
Additional nuances when constructing a garage roof
To successfully complete a roofing project, you not only need to choose the type of roof and materials, but also take into account additional factors:
- Nuances of the design of a garage building. It is worth considering what type of foundation and level of strength the building has, what degree of strength of load-bearing walls and ceilings. Based on these characteristics, it is determined which roofing material is best suited.
- Climatic features of the region. You need to take note of the frequency with which precipitation falls, what wind strength is standard for the region, and the location of the future building.
- Where is the garage? If the garage structure is part of a garage cooperative, then the materials should be selected in such a way that they look harmonious with other buildings.
- Selecting the right tools for the job. During the roofing installation process, you may need different types of tools. To avoid any difficulties, write a list of required tools in a notebook in advance. Then they buy or rent equipment.
Specifics of installing slate and ondulin
Ensure the roof is airtight by performing work according to the following algorithm:
- Install the sheathing. Use boards with a thickness of 15 mm for ondulin, and 25 mm for asbestos-cement slate. Maintain a lathing interval of 30 centimeters.
- Install waterproofing using an underlayment type of roofing felt. Glue the layers with bitumen.
- Lay the sheets, ensuring an overlap of half a sheet. Distortions are not allowed.
- Use special nails that have a seal for fixation.
- Secure the ridge and secure the cornice below.
You are convinced that the overlap technology is simple. Get everything you need and be patient.
Tilt angle
When choosing a roof, you should also take into account its optimal
(permissible)
angle of inclination
: • folded products (having a special form of fastening in the form of seams with a bend, externally they look like sheets with convex stripes): must be inclined at an angle from 18 to 35 degrees;
Seam roof
• corrugated sheeting is recommended to be laid at an angle of 8-20 degrees; • metal tiles are attached at an angle of 25 degrees; • slate – at least 35 degrees; • soft rolled materials – no more than 11 degrees, the maximum angle is not limited;
Roof angle
Laying sheet roofing
Working with sheet material has its own characteristics. Sequence of events:
- Prepare the base by laying vapor and waterproofing. Use roll coatings with anti-condensation characteristics. Using a furniture stapler, lay the film across the surface, ensuring sagging up to 5 centimeters.
- Place square bars with a side of 5 cm on the waterproofing, using self-tapping screws, secure to the rafters.
- Fill the sheathing using boards 15-25 millimeters thick. Provide a sheathing step in such a way as to fix each of the transverse waves of the metal tile. It is important to maintain an interval of 0.5 m for corrugated sheets.
- Fasten the profile sheets to the base with self-tapping screws with an O-ring. Use a screwdriver. Place the screws perpendicular to the surface of the sheet. Screw in without deforming the sheets or pushing through the washer.
- Install wind and cornice strips, install a ridge.
