Roof shingles are sold by both the bundle and by the square. A square of shingles is the quantity needed to cover 100 sq. ft. of roof. Shingles are packaged in paper- or plastic-wrapped bundles designed to be light enough for a person to carry, so heavier shingles require more bundles per square.
Figuring out how many bundles of shingles are necessary for your roof can be of great help when it is time to review contracts from roofers. First, it is important to know the difference between square and bundle.. Roof shingles are sold by the bundle and by the square. A square is 100 square feet. Shingles are wrapped in smaller bundles, which makes them easier to carry up and down a ladder. In most cases, three bundles are equivalent to a square. That means each bundle has just more than 33 square feet of shingles. There are exceptions, however.
