How much does a bundle of shingles cover?

One bundle of shingles covers approximately 33 square feet of roof, depending on the size and weight of the shingles. Typically, it takes three bundles of standard-sized, standard-weight shingles to cover 100 square feet of roof surface.

Bundles are packaged at a weight that is light enough for one person to carry easily. This means that heavier materials may be packaged with fewer shingles per bundle, resulting in a bundle that covers less surface space.

A better way to determine how many shingles are needed is to measure the roof and divide the measurement by 100 square feet. A square of shingles covers 100 square feet, so they are sold by the square, not by the bundle.
