As well as everything, the roof has life cycle after which becomes old and needs repair. If to repair roof there is no sense any more or it is necessary to unite under one roof the house with extensions, it needs to be reconstructed.
Instruction
1. To reconstruct roof, sort it. Replacement can be both full, and partial. Partial - when only the covering changes. The soft roof (roofing material which lies on furring) is changed for the purpose of warming of roof and the house in general. More often the rigid top roof, that is material which has revetted roof spoils. Sheets of covering burst, rust, having served the term, the roof can begin to flow. In case the design does not change, and the woods in good condition, change roof partially.
2. Measure step and section of furring if you are going to cover roof with other material. So, for example, furring under slate can not be suitable for laying by metal tile. Edges of sheet material have to coincide with furring step.
3. Roofing material can be replaced with more modern materials - subroofing film, membrane or anti-condensate film. It is possible to leave former soft roof, having laid to heater layer.
4. You take down all beams and overlappings of roof if have decided to change planning, having arranged the second floor. Before building new, determine its height and tilt angle. The inhabited second floor will demand good illumination therefore it is possible to arrange gable roof with one side pediment where there will be window.
5. Designate on place flooring where pediments will be located, then start installation. Revet with decorative material before construction. You build by means of temporary rafters which will support pediments before installation of constants.
6. Connect front and back pediments ridge board, having established it in in advance prepared grooves of pediments. Record intermediate rafters and temporary racks.
7. Establish couples of bearing rafters. Their number depends on the area of the house: the more the area, the is more than roof support. They will provide additional support. Between couples of bearing rafters establish beams crossing points.
8. Establish beam crossing point under ridge board, on it weight of ridge board of side pediment will lay down.
9. Establish ridge board of side pediment, having connected it to beam crossing point.
10. Execute furring, put soft roof. Following furring and sheets of the main roof.
