The term square in reference to roofing materials refers to 100 square feet of roof area. One square of slate is the amount of slate that it takes to cover 100 square feet of roof area. A 10 foot x 10 foot section of roof would equal one square. So would a 4 foot x 25 foot section. Ditto for a 5 foot x 20 foot.
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 = 8â¦4 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.
