<p>PURPOSE: To prevent the risk of slip by providing a snow stopper on a main roof with a gentle gradient to reduce the projection degree of eaves, and forming a snow sliding surface of a sub-roof projected with a steep gradient more than the main roof at a little space from the eaves. CONSTITUTION: A main roof 1 on the uppermost part of a dwelling house (a) is formed with a gradient two to three tenths, a snow stopper 2 is provided on the upper surface of the main roof 1, and an angle material having an L- shaped section is attached by a metal stopper to reduce the projecting degree of the eaves 3 more than usual. At a little space from the eaves 3, a sub-roof 4 is projected with a gradient four to six tenth. The roof surface of the sub-roof is roofed with fluororesin steel plate where snow is easy to slip, a thick post 9 is fitted in a girder 7 by an ancon 8 made of hard material, and the lower end tenon 10 thereof is elongated to insert a groundsill post 11 in an insert hole 12 to the full. Thus, a snow eaves of the main roof 1 can be prevented from dropping in a large amount at one time.</p> |
