How to make a roof from a profiled sheet in a garage?

Knowing how to make a roof from a profiled sheet in a garage is very important for almost every owner. Having figured out how to cover a gable and gable roof with your own hands step by step, you can eliminate many mistakes. A separate important topic is how to make the crate correctly.

A parking space in the garage is an old dream of many people; a number of others have already managed to implement it. But somehow, vehicle safety and comfort depend not only on walls and foundations, on locks and storage systems.

However, perhaps the best option is to make a roof on the garage from a profiled sheet. This way:

• facilitates the construction;
• simplifies work;
• guarantees durability of use;
• provides corrosion resistance;
• allows you to choose a variety of colors at your discretion;
• relatively affordable.

For reasons of ease of arrangement, many choose a pitched roof. The room below will have unequal ceiling heights. The slope is clearly oriented to one side. The supporting role is played by:

• stingrays;
• front beams;
• tapered strips.

The absence of a pronounced slope forces more energy to be spent on cleaning the roof from snow. And when it rains, moisture will linger longer, which greatly increases the load exerted. The rejection of stressed elements significantly simplifies the circuit, facilitates installation. The service life increases markedly. True, in a strong wind, a single-slope design can be badly damaged, and problems arise with the formation of a full-fledged thermal protection.

Ceiling beams are placed on the Mauerlat. The rafter slope is usually 25 degrees. Important properties of a double slope roof:

• practicality;
• the mandatory need for the arrangement of dormer windows;
• excellent sediment removal;
• the need for more materials than with a single slope;
• increased aesthetics;
• reducing the need for repairs.

It's about designing and schematics. They necessarily determine the required thickness of the substrate and the material body itself. At the same stage:

• decide which brand of corrugated board and its type is better to choose;
• purchase the necessary materials and tools (as needed);
• completing at least the construction of walls and truss structures;
• free up space for work;
• preparing for insulation, vapor barrier, waterproofing and other necessary work.

To make a garage roof from a profiled sheet step by step is both simple and difficult at the same time. It is necessary, in particular, to pay special attention to the execution of the substrate. The type of lathing does not depend on the flat, pitched or gable shape of the roof structure itself. It is also not affected by the overlap of the profiled sheets. And here The role of the profile size should not be underestimated - meanwhile, even qualified craftsmen sometimes make just such a mistake.

However, they not only eliminate the original naturalness of the material - which is important, additional costs appear. If boards are nevertheless chosen, their width is more than 15 cm is impractical.

Stainless steel is more expensive, but it pays off for a longer service life. The reliability of steel structures is beyond doubt. The general slope of roof structures plays a decisive role in calculating the parameters of the lathing. On each slope, the calculation is made separately. This eliminates many serious errors and misunderstandings.

The first boards should be fixed to the eaves. The edges of any mutually touching elements must necessarily be connected on a common rafter leg. The horizontal level should be kept as strictly as possible. Sometimes you even have to take thin boards for lining. They work in a similar way around the ridge beams.

The distances between the intermediate parts attached to the rafters are determined by the brand of the corrugated board. It is better to immediately clarify this circumstance with the sellers - then it will be easier to lay the crate. We must not forget about the counter grill, which has important ventilation functions. Fasteners should be suitable for the thickness of the lumber or steel. Otherwise, this procedure does not present any difficulties for a more or less experienced person.

It is absolutely impossible to lay roofing material correctly without insulation. But the insulation itself justifies itself only with careful arrangement of waterproofing. The membrane is placed over the entire volume; even single free joints and empty areas are not allowed. The easiest way to attach the membrane material is using a construction stapler. If the process of arranging thermal insulation itself is planned to be built as efficiently and quickly as possible, then you can resort to using polyurethane foam.

The insulation parts should be adjusted to the gaps dividing the rafters. It is advisable to use a painting knife. It is most rational to fasten the heat-shielding element with a nylon thread. Additional retention is provided by 5x5 cm slats. Since compression harms the mineral wool, it must have the most accurate dimensions - then problems are excluded.

Covering the concrete roof of a garage with or without an overhang with a profiled sheet after insulation and lathing work is not so difficult. However, you will have to carefully check the material itself. It is useful to always require the presentation of a certificate of quality. In the absence of such a document, it makes no sense to trust the products. If an attractive appearance and optimal service life are critical, you can order a material with a plastisol or PVC coating - however, this is no longer a budget solution.

On a flat roof, whose slope is about 5 degrees, either universal sheets with high profiles or load-bearing modifications are placed. On slopes, HC or a wall product with a high corrugation is preferable. If you have to cover with your own hands a garage adjoining the house or an autonomous brick-built garage, you need a Mauerlat.

Such a structural element is also needed in a block building. A beam with a size of 10x15, sometimes 15x15, is placed on top of the reinforced part. Fixation is carried out using studs, anchor bolts. For your information: on medium-sized structures, the Mauerlat is installed without sidewall reinforcement. But in this case, it is required to clearly calculate all the loads.

If the overlap of the garage meets high aesthetic requirements, eaves and wind boards can be attached to it. However, this is not necessary at all.

It is possible to lay a profiled sheet on a gable and a gable roof according to approximately the same scheme. The rafter legs are covered with waterproofing foil. It is not worth pulling it, some sagging must be left. The strips are laid from the low edge of the roof. Their overlap should be 10-15 cm.

It is most correct to close the entire slope with the profiled sheet itself for the entire length. When this is not possible, the panels are installed starting from the low section of the slope. The overlap between them is at least 15 and not more than 30 cm.

It is advisable to lift the professional sheet up along the lags. Experts advise to wait for calm dry weather. Other recommendations:

• fix the sheet on self-tapping screws with a polymer washer;
• make horizontal overlaps to prevent moisture leakage;
• pre-seal the roof sloped by less than 12 degrees;
• thoroughly level the first sheet;
• align the position of the second sheets, focusing on the first;
• attach the corrugated board to the crate with self-tapping screws (4 pieces per sq. m, in difficult cases - 5 pieces);
• fix the strips of the end and ridge support when the entire roofing array is laid and secured (without strong attraction so that air can circulate freely);
• complete the work by equipping difficult areas, such as points of attachment to adjacent walls, ventilation outlets.

It is advisable to take self-tapping screws corresponding to the tone of the roofing. Droppers are almost always put. Fitting the sheet to size always takes place on flat areas. Cutting is most conveniently done with power tools with disc attachments. Abrasive discs - including those on angle grinders - are unacceptable.

It must be remembered that the angle of inclination and the strength of the structure are inversely proportional. You cannot change the size of the overlap during installation. Therefore, it should be calculated in advance and very carefully. It is unacceptable to reduce the number of self-tapping screws in comparison with the universal design requirements. It is recommended to apply a bituminous primer over the concrete to increase the strength.
