Standard roof construction

Before you make the roof of the garage, you mustdecide what will be the roof - pent or gabled. They differ among themselves design, complexity of work, amount of material required and the possibility of a full attic equipment.

Driving the garage roof

The circuit arrangement of the garage roof

Pent roof garage settling when the garage adjacent to theother buildings or a part of them. For this construction, set sloping hanging rafters that rest on two pillars. For a stable and robust design should take into account the size of the garage. If the width will be no more than 4.5 m, then the rafters are placed on a support at a certain angle and are fixed there. This design is considered to be easy. Sophisticated design rafters pent roofs applicable in the case where the distance between supports 4.5 m to 6 m. For this construction, it is necessary to install braces that will enhance it.

Gable roof garage it is advisable to establish separategarages. This roof is an isosceles triangle. It can be set to any size garages, above all, correctly calculate the angle. Truss construction consists of two rafters, joined together at the top. It relies on the rafters load-bearing walls.

Set single-pitch gable roof and garage with his hands just enough. But in order to facilitate the execution of works, they must carry two or three.

The device of the garage roof

Regardless of the type of the roof consists ofrafters, battens, roofing, waterproofing and heat. Each of these elements settle in due time. For mounting one or two slopes roof has its own rules and calculations to be carried out before proceeding.

Construction of pent roof

The slope pent roof

The slope of the roof pent selected depending on the roofing material

As noted earlier, pent roofis an inclined structure, the ends of which are based on two pillars. In order to properly construct a roof, you need to calculate the height difference of the walls, on which it is based. The angle is chosen according to the material that will be used. The difference is calculated as follows:

H = b * tan »a»;

Where, b - width of the garage, «a» - the angle of inclination (slope) of the roof.

Now you can start the installation of truss construction:

  • on retaining walls laid mauerlat (reference beam section 120x120 mm and 100x100 mm);
  • mauerlat attached to the wall by means of anchor bolts;
  • in the rafters at the joints with mauerlat cut down mounting slot;
  • rafters put in place and secured by anchors or nails;
  • on top of the rafters set the wooden crate.

Important! Quite often I shed roof made of concrete slabs. The angle of inclination of the plates to 15 °, and laid on them is advisable soft roof.

Construction of gable roof

Rafters for a gable roof

For the arrangement of the gable roof rafters set the isosceles triangle

Gable roof isisosceles triangle: rafters are connected to the "ridge" (highest point of the roof), boards the same length of the rafters. For the construction of such a roof is necessary to calculate the length of the rafter feet and the height of the "ridge". To do this, use the following formula:

Ridge height H = 0.5 * b / tan ( «a» 2);

The length of the rafter C = 0.5 * b / sin ( «a» / 2);

Where b - width of the garage; «A» - angle.

Important! To make a visor projecting beyond the structure, it is necessary to add the length of the rafter another 50 cm.

To create a gable roof, do the following work:

  • on the wall on the perimeter of the building laid mauerlat and fix them;
  • rafters produce a pattern. To do this, take the board, equal in length to the distance between mauerlat. One of them laid on mauerlat two others set at an angle so that they met in the ridge ends. After that, strictly in the middle set up perpendicular to the support equal to the height of the ridge. Bonded to each other boards, hammering in nails or screwing them with screws. We should get a rafter pattern. According to it, cut out the rest of the rafters;

Important! To be able to adjust the template rafters of the boards do little more than required.

  • When you're done, set the first pair of extreme rafters and fasten them with the anchors;
  • stretch the cord on the level of the ridge to the accuracy of the installation of the following rafters;
  • set remaining rafters steps 0.7-1.2 m;
  • the rafters fills crate of wooden boards 25x30 mm.

What and how to equip the roof

Before you build a garage roof, should bechoose the material for the roof. Difficulties with the choice of roofing materials on the market do not have, but on what type of material will be used, depends on the angle of inclination of the roof. To know how to make the roof of the garage roof to securely laid, it is necessary to take into account the minimum and maximum angle of the truss construction. Another important point for the arrangement of the rafters of the roof is the mass, the larger it is, the thicker the rafters have to use. Table №1 contains rafters dependent angle of inclination on the type of roofing material.

The dependence of the roof pitch (slope) of the type of roof

Table №1. The dependence of the roof pitch (slope) of the type of roof

Typically, a preference for a particular materialgiven depending on its availability and ease of styling. The most common materials for the roof of the garage are - roofing, corrugated, galvanized metal, Slate (asbestos sheet). Using these materials, you can manually perform all roofing work.

The roof of roofing material

Roofing roofing material

Roofing roofing material in several layers - the best option for shed roof

This is one of the most common and affordableroofing materials. Laying of roofing material should be made on a continuous basis. It can be a concrete floor slab or solid wooden crate. Because of its quality roofing material has a dual function - creates a solid inexpensive coating and protects from rain.

Roofing material relates to soft roofing materialsroll type which facilitates its installation. To make the quality of the garage roof using roofing material, it is necessary to lay two or three layers. The first layer is the backsheet, and will have subsequent main roof covering. To create high-quality roof of roofing material the following milestones must be met:

  • it is first necessary to establish the foundation for the roof;
  • further base coat with mastic asphalt andplank first layer of roofing material. To perform quality work, you must promazyvat mastic asphalt surface immediately before the stacking and then rolled and pressed roofing material;

Important! Coat with bitumen is necessary over the entire width of the roll of roofing material with a small indentation for later paintings. Fabrics roofing material must be laid overlapping, came in with 15-20 cm is especially important next moment -. Begin to lay roofing material must be from bottom to top in the direction of the roof slope. With this installation the water will not flow into cracks and joints between the webs.

  • the next layer is laid roofing similarly. The only difference is the direction of stacking - perpendicular to the direction of the first layer;
  • finally, the resulting roof again coat with mastic asphalt over the entire area.

In addition to roofing, there are other softroofing bitumen and polymer-bitumen roll type laminates. They can be laid on a bituminous mastic or by means of a gas burner. The second method requires more attention to the performance of works and is quite a fire hazard.

Laying slate, specificity

slate roofing

Slate roof - the most common variant

Slate as roofing The material was widelyspread due to its low cost, availability and durability. The roof is made of this material is easy to operate and can last for about 40 years. Stacked slate is similar to a professional flooring, but unlike him, the slate has a large mass and requires a solid and reliable truss construction. For rafters, use pieces of wood section 80x100 mm. Thermal insulation and waterproofing of the slate roof is performed by analogy with the floorings.

Metal garage roof

The roof of corrugated sheets

The roof of corrugated board - the modern version of

This kind of one of the roof light in weight thatlargely saves the cost of equipping the frame rafter and battens. To create rafters for the metal will be sufficient to use the bars section 50x50, 30x50 or 30h100 mm. Which one to use depends on the load on the truss structure.

To create a high-quality metal roof of herneed to insulate and seal the. Thermal insulation in a roof is placed between the rafters, and waterproofing materials directly under the roof deck. To create a roof, do the following:

  • create rafter frame and crate of wood;
  • battens laid on the surface of the waterproofing. For these purposes it is possible to use polyethylene film 200 microns thick. Samu anchoring the film to the crate using thin strips section 20x20 mm, step mounting rails do 50-70 cm;

Important! If the decking roofing material used, the step slats chosen such that they tightly lay a sheet of corrugated board.

  • We laid on top of the roof waterproofing of metal. Profiled anchoring to the crate by means of special screws, for the convenience of pre-drilling a small hole in the metal and wood;
  • insulate a roof should be inside the garage. Thermal insulation should be laid between the rafters and fix it with thin strips.

Important! Insulation is necessary to cut and laid in such a way that there are no cracks and gaps between the pieces of thermal insulation and rafters.

If you plan to stack the classic standing seamthe roof of the galvanizing, then there can not do without special tools and specific skills. If the creation of a roof of corrugated board can do on their own, for the standing seam roofing have to invite a professional roofer that will entail additional costs.

Regardless of the form of roofing materials andall types of roof work should be carried out with high care and attention to detail. The roof of the garage must be robust and reliable in order to safeguard the vehicle from the various precipitation and their devastating effects. Construction of the garage roof requires relatively high labor costs, so help team-mate will be very useful.
