In terms of safety of garage of the most reliable the roof from the reinforced concrete slabs covered with the rolled built-up materials is. In terms of design it is better other the gable roof with metal tile looks. However, if your garage does not exceed in width of 3-3.5 meters, the single-pitch roof staled or professional flooring will be the most economic and easy in the device.
It is required to you
- - wooden bar with minimum dimensions of 100х100 mm or logs with a diameter about 150 mm;
- - bar of 60х150 mm;
- - cut or edging board;
- - roofing professional flooring or slate;
- - roofing material;
- - construction fixture (nails, self-tapping screws);
- - carpenter's tool;
- - screw driver.
Instruction
1. Calculate necessary difference of height of the parties of garage on which inferior purlins will lean (supporting beams which are put on walls of buildings and are support for floor beams or rafters). If the inclination of roof is sent to one of sides, it is necessary to define difference of their height. The minimum tilt angle of the single-pitch roof covered with professional flooring is accepted equal 14 °. For garage 3 m wide the difference of heights of walls will be equal 3*0.2493 = 0.7479 m where 0.2493 – tangent of angle 14 °. Thus, one party has to be higher another not less than on 75 cm. Before being accepted to construction of roof, it is necessary to provide this condition.
2. Twist anchor bolts which inferior purlins will fasten to walls in top of side walls. Their diameter has to be 12-14 mm, quantity – not less than 3 on one beam. Length of speakers from walls of the ends has to be more than thickness of beams.
3. Put two layers of roofing material over walls. Drill in opening beams under anchors. Lay inferior purlins on walls so that anchors have passed through openings. Establish on bolts of washer and strong tighten nuts.
4. Lay rafters. For this purpose cut under them in inferior purlins grooves of 40-50 mm in depth. In case further it is supposed to warm garage roof, the distance between rafters is desirable to establish 58-60 mm – under the size of standard plates of warming. Rafters have to have departure in relation to garage walls on 30-40 cm. You fix them to inferior purlins two nails directed at an angle towards each other and in addition brackets which ends have to be divorced on 90 ° from each other.
5. Beat obresht from cut or edging board. There is no need to do it continuous, however its surface has to allow to lay over it waterproofing. Lay roofing material from bottom edge of slope to top with overlapping by top layer of lower.
6. Lay roofing material. When using slate as ukryvny material, stack it directly on waterproofing. Begin laying from below up. Hammer slate nails into wave crest.
7. When using roofing professional flooring it is considered it necessary to beat over waterproofing additional obresht. This requirement is caused by the fact that on inside face of metal sheets condensate can be formed, fight against which will require good ventilation. If the roof is not going to be warmed, this requirement can be neglected, otherwise it is desirable to execute it.
8. Beat on waterproofing spacing rails along slope from top to down on lines of rafters, across these rails lay obresht for professional flooring with step of laying of boards about 300 mm.
9. It is convenient to equal length of roof to have length of sheets of professional flooring. As this material is released up to 12 m long, it is possible to provide such size of sheets upon purchase. As fixture when laying professional flooring self-tapping screws with washer from neoprene are used, they are installed in hollows of profile. Edges of sheets in the bottom of and at the top of slope fasten to each hollow, median zone of leaf – through one. The distance between ranks of fastenings has to be about 500 mm.
10. Put brick and solution of opening and emptiness which are available between walls and roof. Make of professional flooring and establish on the top edge of roof curved profile which has to close faces of rafters and obresht from rain and snow.
