Best ResponseYou've already chosen the best response.0dw:1438732171291:dw Given this info, how do I find these lengths so I can know how many shingles to buy

Best ResponseYou've already chosen the best response.1It depends on how high the attic above it's support. Did you make that measurement?

Best ResponseYou've already chosen the best response.03 ft is the height of the attics roof if youre talking about the house , i dont get how that will help

Best ResponseYou've already chosen the best response.0basically the height of the whole attic (instead of saying attics roof_ because the attic is the roof itself

Best ResponseYou've already chosen the best response.1The height definitely changes the area of shingles. A steeper roof requires more shingles than a near flat roof. Here you have a relatively flat roof, and you would need about 1114% more than the plan area, so a total of 13*22*1.14=326 sq. ft. Allow extra for the overlaps at the crest, ridges, and return around the bottom. Note that this is an estimate based on the measurements. Actual area depends on how you measure and how you work. Do not expect this to be accurate to the shingle or anywhere near that.

Best ResponseYou've already chosen the best response.0Yes but I just want the lengths for those two hips for the roof am i just supposed to multiply the height and length

Best ResponseYou've already chosen the best response.0I tried by multiplying and I got 39 ft a half of that would be 19.5 ft would that be the length of one hip of the roof

Best ResponseYou've already chosen the best response.1Are you covering the whole roof with shingles?

Best ResponseYou've already chosen the best response.1There is not enough information given to calculate individual pieces if 3' is only the height. But I estimated the total area of the sloping roof for you as long as you're covering the whole roof. However, you have to make adjustments for overlaps and wastage.

Best ResponseYou've already chosen the best response.0yes with shingles and I really don't have information because the roof is not yet created

mathmate

Best ResponseYou've already chosen the best response.1As I said, I have estimated the area of the sloping roof, but you will have to make adjustments for wastage and overlaps. Perhaps it would be safe to add 15 sq. ft for the two ends which have a steeper slope, so that makes about 340 sq. ft. + wastage+overlap.

Best ResponseYou've already chosen the best response.0yeah i have no experience in this kind of construction work just trying to help out a close friend with their house and they saidd they needed the measurements for the two roof stands/hips given that information

Best ResponseYou've already chosen the best response.0also let me add one more thing , so it really shouldn't be done with math right i should choose the right lengths that fit

Best ResponseYou've already chosen the best response.0im still a bit confused about the hip rafter length though, you get what im saying? Should I decide the length of the rafter as x/12 after i find the area of the house?

Best ResponseYou've already chosen the best response.0im not good with this topic its my first time so i only have a sketch of it not a 3d diagram and i just want the measurements for the two roof legs that make it rise really im stuck on how to figure it out

Best ResponseYou've already chosen the best response.0Use pythagorus to find the missing sides of the rightangled triangles

exoticinspirit

Best ResponseYou've already chosen the best response.0I thought you just had to do this Find the surface area 2(wl+lh+hw) So 2(22x13)+(13x3)+(3x22)=457 ft^2 and with this i can find the length of the roof pitch OR do I just make up the roof pitch for whichever is safe for the roof. Also I did try the pythagorean theorem if thats what u mean i got 19.5

UnkleRhaukus

Best ResponseYou've already chosen the best response.02(wl+lh+hw) is the surface area of a rectangular prism, so that wont work

Best ResponseYou've already chosen the best response.0oh.. facepalm the only formula that would work is the Pythagorean for the triangles then yea?
