How Many Bundles of Shingles for 600 sq ft?
600 sq ft of roof surface is 6 roofing squares. With 10% waste and standard 3-bundle-per-square shingles you need 20 bundles. If 600 sq ft is the house footprint rather than the roof, multiply by the pitch factor first: at a 6/12 pitch that becomes 23 bundles.

If 600 sq ft is the house footprint
Shingles cover the sloped roof, not the floor plan. Multiply the footprint (including overhangs) by the pitch factor to get roof surface:
