Back surfacing

Back surfacing refers to a layer of material that is applied to the back or underside of roofing shingles or other roofing materials. The back surfacing layer is typically made of a granular material, such as sand or mineral granules, and is applied to the back of the shingle or other material to provide additional protection and durability.

The back surfacing layer can help to prevent the shingle from sticking to other materials during storage and transport, and can also provide additional protection against moisture and other types of damage. The layer of granules can help to absorb impacts and resist wear and tear, and can also help to improve the overall appearance and performance of the shingle or other roofing material.

Back surfacing is typically applied during the manufacturing process of the shingle or other roofing material, and is an important part of the overall design and construction of the product. The quality and durability of the back surfacing layer can have a significant impact on the performance and longevity of the roofing material, and proper installation and maintenance of the roof can help to ensure the continued durability and performance of the roof system.
