A roofing material composed of asphalt-saturated and coated felt or fiberglass, manufactured in long rolls, is a common low-slope roofing solution. This product is typically installed in overlapping courses, sealed with roofing cement or a torch-applied adhesive, to create a waterproof barrier. Its application is frequently seen on outbuildings, sheds, and other utilitarian structures.
The utilization of this material offers several advantages, including relative ease of installation and cost-effectiveness compared to some alternative roofing options. Historically, its development and use have been driven by the need for an affordable and quickly deployable weatherproofing solution, particularly for large or low-incline surfaces. The longevity and performance characteristics can vary depending on the quality of the material and the expertise of the installation.
