What to do with the number
Gables, corners, openings and panel layout influence offcuts and accessory quantities. Calculate gables and rectangular wall sections separately for a better takeoff.
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
