NOTE: Depending on the pitch of the roof, gables and more cut-up areas will produce
a higher scrap rate.
Rectangular wall surfaces
Measure height (excluding gables).
Measure width (including doors
and windows).
Repeat for remaining walls.
x =
(height) (width) (surface area)
Tri an gu la r ga bl e e nd s ur fa ces
Measure height at center (add 1’ to

divide by half.
Repeat for remaining gables.
