Soft roofing materials have two main advantages – the low price and ability to cover any difficult surface. And it, certainly, apart from the fact that they qualitatively perform the main function – reliable protection of buildings against atmospheric precipitation.
It is required to you
- – bituminous tile;
- – construction tool (axe, saw, hammer and so forth);
- – OSB plates;
- – fixture (normal and roofing nails);
- – glue for flexible tile;
- – lining rolled material;
- – metal eaves and pediment sections.
Instruction
1. Lay on rafters the basis (obresht) under soft roof. As material for it use eaves board, plywood or plates of OSB. The base has to be solid and equal. Its thickness at step of rafters to 600 mm has to be not less than 20 mm for board and 12 mm for plywood. At increase in step of rafters also thickness of the obreshet has to increase respectively.
2. Obresht the designs passing through roof (flues, ventilation pipes) in exit points on upholster on perimeter with wooden level of triangular section – for providing smoothness of transition of surfaces and possibility of fastening to it nails of roofing materials.
3. Lay on the basis rolled lining material (roofing material, Ruflex and so forth). Lay material horizontal strips, beginning from bottom edge of roof, with overlapping by top layer lower not less than on 10 cm. Sheets you fix at the edges roofing nails with interval of 20 cm. Stick together joints of strips bituminous pitch.
4. On the bottom and side edges of roof establish eaves and pediment metal sections (droppers) – for protection of edges of roof against moisture. Joints of the next levels have to block each other on 20 mm. Carry out fastening roofing nails, hammering them into levels in zigzag fashion with step of 100 mm.
5. Over lining material and metal sections lay eaves tile (at edges of roof) and endovy carpet (on valley gutters). Before laying of the first remove film from its lower face. The sheet edge of tile has to be removed from edge of metal level on 10-20 mm, connect the next sheets with each other end-to-end. Paste the Endovy carpet glue for tile and in addition beat at the edges roofing nails.
6. Begin laying of ordinary tile with roof bottom from the central line of slope. Before laying remove protective film. The lower edge of lobes has to defend on 10 mm from edge of eaves tile, lobes have to block all joints of the last.
7. Beat each leaf of tile four-six roofing nails, having them groove edges are 20-30 mm higher. Stack the following number of tile so that the edge of its ledges was located on one line with edge of hollows of underlying row. The detailed scheme of laying is stated in the instruction to tile.
8. At edge (pediment) edges of roof cut off tile on the line coinciding with edge of metal section. Paste its edges glue for tile. In valley gutters cut off tile so that there was open fifteen-centimetric strip of endovy carpet. Miss the mark edges of tile along the valley gutter on 10 cm with glue and densely press to the carpet lying under it.
9. Separate each leaf of ridge tile into three parts (in places of perforation) and lay them the short party along the fad with overlapping of edges of each other of 5 cm. Before laying do not forget to remove protective film. Beat each leaf of ridge tile 4 nails (on two from each party of slope). Hats of nails have to be blocked by edge of overlying leaf.
10. Miss the mark vertical surfaces of flues and pipes with bituminous mastic and paste on them lining material – in the form of the protective apron falling by roof. Paste its edges falling on roof glue for tile, attach top to pipes metal tension member, having sealed its joint on perimeter of pipes with bituminous mastic or sealant.
