How to Use the Calculator

  1. Enter the length, width, and thickness of your shingle in inches. These measurements should be obtained from the shingle packaging or specifications.
  2. The material density is pre-filled for common asphalt shingles (40 lbs/cu ft). If you're using a different material, adjust this value accordingly.
  3. Click the "Calculate" button to compute the weight of the shingle and its weight per square foot.
  4. The calculator provides the total weight of the shingle and its weight per square foot, which is useful for determining the load on your roof.

Understanding Shingle Weight

The weight of roof shingles is an important factor in roofing projects. Heavier shingles may require additional structural support, especially for older homes. The weight per square foot helps you estimate the total load on your roof and plan accordingly.

Common Shingle Weight Ranges

  • 3-tab asphalt shingles: 7-10 lbs per square (100 sq ft)
  • Architectural shingles: 9-17 lbs per square
  • Dimensional shingles: 11-24 lbs per square

Note: These are general ranges. Always refer to the manufacturer's specifications for exact weights.
