Field notes
Waste climbs with corners, not square footage. A plain gable end runs 10%; a house with dormers, bays, and multiple gables can waste 15% because every angled cut leaves an unusable offcut. Measure each wall separately and subtract only the big openings — trying to net out every window invites a shortfall. Buy one extra square and keep it for storm repairs; dye lots shift between orders.
