All imagine roof of owner-occupied dwelling which parties form triangle. Over rafters furrings the roof is put, and, it seems, the algorithm is clear. However, at the seeming simplicity, roof - the most difficult part of construction of the house.
Instruction
1. Calculate tilt angle of roof and height. These indicators are defined by area weather weather conditions. The pleasant inclination of 45 degrees will not be suitable for the area with strong winds, but will be ideal in the region where a lot of precipitation drops out. Besides, the degree is defined by planning of roof and material by which the roof will be dimmed. For example, the metaltile roof allows the minimum inclination of 14 degrees. It is possible more, it is less – no, otherwise under tiles moisture will get.
2. On the central line of width of flight of the house establish vertical support. The step between flights can reach 4.5 meters. On vertical support put the fad - it is the upper edge of roof from which slopes will go.
3. Establish the roof basis - stopil. These are wooden bars which serve as "skeleton", - under them in future house there will be attic. All rafters have to stand on roof under identical bias.
4. Make furring of rafters which is necessary for roof flooring. For furring usually use boards or tes. It is possible to stack them with gap or closely - depends on material with which you will cover roof. For example, roofing material creeps on continuous furring.
5. After furring is ready, begin to lay roof. As the first layer - soft roof - roofing material which provides waterproofing is usually used. You lay roofing material in two layers. The first along slope, the second across from below up with an overlap on 120-140 mm. Surely level soft roof that there were no waves and roughnesses. Fix by rails and nails or screws.
6. Begin to put flashing sheets from below up. It becomes in order that under them moisture has not got. Establish the first flashing sheets closely to the lower bar of furring. Attach these sheets screws. Close joint of sheets the metal fad of roof, attach it to furring screws. Establish the following sheets of roof, covering previous down with an overlap. You watch that seams coincided at the left and on the right. Fix sheets and the fad.
