Chalk

Home / Glossary

Chalk refers to a powdery residue that may form on the surface of roofing materials, such as asphalt shingles, due to weathering or exposure to the elements. Chalk is a natural byproduct of the aging process of roofing materials and is often a sign of wear or degradation. The amount of chalk that accumulates on the surface of roofing materials can depend on various factors, such as the type and quality of the materials, the amount of sunlight exposure, and the local climate. Chalk may be seen as a white or grayish coating on the surface of the roofing material, and it can be an indication that the roofing material is nearing the end of its useful life and may require replacement.
