Description

Underfelt #30, also known as #30 roofing felt, is a heavy-duty, asphalt-saturated underlayment used beneath roofing materials for added protection. It acts as a secondary moisture barrier, helping prevent water infiltration from wind-driven rain or ice dams. Made from organic or fiberglass-based materials, it provides excellent tear resistance and durability in various weather conditions. Commonly used in both residential and commercial roofing, it’s compatible with asphalt shingles, wood shakes, and tiles. Easy to install and compliant with industry standards, #30 underfelt enhances roof longevity and structural integrity.
