TL;DR
A square of roofing is the trade's unit of roof area equal to 100 square feet, the basis on which materials are bundled and jobs are priced. Three bundles of standard architectural shingles cover one square, and estimates add roughly 10 to 15 percent waste for ridges, valleys, and starter courses.
What it means
A square of roofing is the trade's unit of roof area equal to 100 square feet, the basis on which materials are bundled and jobs are priced. Three bundles of standard architectural shingles cover one square, and estimates add roughly 10 to 15 percent waste for ridges, valleys, and starter courses. Knowing that a typical American roof runs 20 to 30 squares lets a homeowner sanity-check both the measurement and the per-square price on competing bids.
