Are you posting up your homework because you're too lazy to do it?
No, I already did it, but then I started to question whether I had enough information to do it correctly or not.
Also, without knowing the roof pitch, it's impossible to tell the sq footage of roof.
$4700 in roofing materials + labor . That doesn't include decking. Don't forget gutters & down spouts. Which will get trashed by the tear off crew. Throwing another $4200 in materials.
This is a roof with a slope, so you can't just turn this into two rectangles of 34'4 x 23'5 and 13'7 x 33'4.

It shouldn't matter since all the measurements were taken on the surface of each "shape." You're looking at the actual measurements, so I guess the eaves would be in scale with the ridges, and the hips in scale with the valleys. On this roof anyway, where everything is the same slope.Quote:
