How many bundles of shingles are needed for one square?

To determine how many bundles of shingles are needed for one square, it is essential to understand the definitions used in roofing. In roofing terminology, a "square" covers an area of 100 square feet. Standard bundles of asphalt shingles typically cover about 33.33 square feet each.

Since one square is equal to 100 square feet, when you divide 100 by the coverage of a single bundle (33.33 square feet), the result is approximately 3. Thus, approximately three bundles are needed to cover one square. This calculation reflects the general industry standard, which is why the answer is three bundles.

This approach also aligns with common roofing practices. Each roofing project may vary slightly based on the type and manufacturer of shingles, but fundamentally, three bundles remain the accepted quantity needed to cover one square correctly.
