What is the typical weight range for heavyweight dimensional shingles per square?

• A. 265-350 lb./sq.
• B. 100-150 lb./sq.
• C. 500-600 lb./sq.
• D. 150-200 lb./sq.

Answer: (A)

Weight per square for heavyweight dimensional shingles is defined as the total weight of 100 square feet of shingles, used to size material handling and roof load. Heavyweight dimensional shingles are built thicker and with more asphalt and mineral fill than standard shingles, which raises their weight. In practice, manufacturers list a typical weight range around 265 to 350 pounds per square. This is the best answer because it reflects the actual heft of these products and matches the standard references used in installation planning. Lighter ranges correspond to lighter or standard shingles, and weights in the 500–600 pound area would exceed what is typical for dimensional shingles. Understanding this helps you plan for deck load, lifting, and fastener requirements when working with heavier shingles.
