What is roll roofing typically made of?

Roll roofing is typically made of coated felts, which are comprised of a base material saturated with asphalt and coated on the top with mineral granules or a similar protective layer. This construction allows roll roofing to be lightweight, easy to install, and economical. The materials used in roll roofing give it the characteristics needed for covering large flat or low-slope roofs efficiently.

Other options like metal sheets and concrete tiles serve different roofing purposes and have distinct installation techniques and weight considerations compared to roll roofing. Shingles are also different in that they come in individual pieces, offering a different aesthetic and performance profile than the continuous sheets used in roll roofing. The unique makeup of coated felts makes it the ideal material for this type of application, especially in more industrial or commercial settings where cost and practicality are of higher importance.
