How much dose 3 square of roofing cover
3 bundles = 1 square 10 2/3 sq x 3 bundles = 32 bundles
two and one tenth.
Not sure, but one bundle covers 33.33 square feet. 3 bundles to a square.
Roofing shingles. Standard grade 3 per square. Architectural 4 per square.
9 bundles assuming std. 3 bundle/sq. shingles
Most shingles come 3 bundles per square(100 sq. ft.), so you would have 4200 bundles for 1400 sq, but only 42 if you are asking about 1400 sq. ft.
typically a square is three bundles (about 26 shingles per) but in some types of architectural shingles there are four bundles per square to make them easier to handle.
A 'bundle' is an arbitrary amount - Usually we talk about 'squares' in roofing. One 'square' is 100 square feet
That would be one square and one bundle. Better buy a square and two bundles, though, to cover wastage.
