I was thinking a flat roof with tar paper and the like but an angled metal roof with spray foam on the underside, or good insulation on the roof, 1inch of spray foam on the flat roof. Flat roof for the actual roof but the metal to keep the water off

Nice, I knew I was off somewhere!
Yes, asphalt shingle.
For all materials I am going to assume at the very least 10% waste, maybe more like 12% to guarantee the price quote I make my self is the Max needed

Ok, so I'm planning a building. Its 30' x 30' and the trusses will be 4/12. With a 12" overhang. What I am confused about is the length of each half of the roof (peak to lower edge). I'm just looking for someone to confirm my maths lol So, 4/12 means every 12 inches from the edge it goes up 4 inches toward the peak. The trusses are 30' + the 1' overhang on each end so that's 32' 32 ÷ 2 = 16. (Were trying to make a triangle to solve for the longer side to know the length of the angled roof) 16 * 4 = 64 (64 inches, 5' 4") We now have 2 sides and an angle (  ° cause we cut a triangle in half) so.... we get around 16' 11" for the surface that will be the roof.... That's 507.5 sqft right? (30' * 16' 11") I focused my self doing that.... lol. Or for the whole roof its 1015sqft |
