Roofing squares: total area (with waste) Γ· 100. Each square needs 3 bundles of shingles, 1.5 lbs of roofing nails, and coverage from underlayment rolls. Add 15% waste for a typical gable roof, 20% for hip roofs.

Don't forget accessories: ridge cap shingles (one per 10" of ridge), drip edge (one 10' piece per 10 feet of eave and rake), and flashing for valleys, walls, and penetrations.

30 Γ— 20 ft roof + 15% waste = 6.9 squares = 21 bundles of shingles, 1 roll underlayment, 11 lbs nails, 38 ridge caps, 10 drip edge pieces.
