How many bundle of roofing shingles to cover 2800 square feet?
Roofing is sold by the “square” which is 100 square feet per “square” and there are 3 buncles per square. A 2800 square foot roof = 28 squares x 3 bundles per square = 84 bundles. Add about 10% (3-4 bundles) for trim waste. This is pretty accurate for a simple hip roof. A roof with multiple valleys can take a bit more.
