    |dw:1438732171291:dw| Given this info, how do I find these lengths so I can know how many shingles to buy

    It depends on how high the attic above it's support. Did you make that measurement?

    3 ft is the height of the attics roof if youre talking about the house , i dont get how that will help

    basically the height of the whole attic (instead of saying attics roof_ because the attic is the roof itself

    The 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 11-14% 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.

    Yes but I just want the lengths for those two hips for the roof am i just supposed to multiply the height and length

    I 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

    Are you covering the whole roof with shingles?

    There 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.

    yes with shingles and I really don't have information because the roof is not yet created

    As 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.

    yeah 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

    im 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?

    I 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

    2(wl+lh+hw) is the surface area of a rectangular prism, so that wont work
