How much do laminated asphalt shingles generally weigh per square?

Laminated asphalt shingles typically weigh between 250 to 300 pounds per square. This weight range is characteristic of laminated shingles, which are designed with multiple layers to provide added durability, aesthetic appeal, and resistance to weather conditions. The added materials and construction techniques contribute to the higher weight compared to traditional three-tab asphalt shingles, which generally weigh less.

Understanding the weight of laminated asphalt shingles is crucial for various reasons, including the structural integrity of the roof, load-bearing considerations, and determining the appropriate support systems during installation. Familiarity with these specifications aids home inspectors in assessing roofing materials, ensuring they align with the expectations for safe and effective construction practices.
