What is the weight range for a square of 3-tab shingles?

The weight range for a square of 3-tab shingles typically falls between 200 to 240 pounds. A square in roofing terms refers to the area covered by 100 square feet. 3-tab shingles are designed to be lightweight compared to other types of shingles, making them a common choice for residential roofing projects.

Understanding the weight of shingles is crucial for several reasons. First, the weight influences shipping costs, installation, and the structural support needed for the roofing system. Therefore, having the correct weight range is essential for contractors and homeowners alike.

The other weight ranges stated do not accurately reflect the typical specifications for 3-tab shingles. Lower ranges may not provide a sufficient representation of the materials used, while higher ranges suggest heavier architectural shingles or different roofing products altogether. This weight consideration is important for ensuring both compliance with building codes and the longevity of the roof.
