Built-up felt roofing is a time-tested solution made up of multiple layers of bitumen (asphalt or coal tar) and reinforcing fabrics like fiberglass or organic felts. These layers create a robust, waterproof membrane, ideal for flat or low-pitch roofs.
Installation matters. To get the most out of your felt roof, it’s important that it’s applied properly. At CRS, our team of experienced professionals installs, replaces, and repairs a range of hot and cold applied elastomeric felt systems, all backed by manufacturer guarantees and warranties.
