                                Roofing Cement FAQs

                                • Is roofing cement waterproof?
                                  Is roofing cement waterproof? Designed to avoid cracking, plastic roofing cement can withstand cold weather and is resistant to melting in high temperatures. However, most roofing materials can deteriorate and its waterproofing ability lessens over time.
                                • How long will roof cement last?
                                  Depending on the efficacy of the application, the area, and the surface where it is applied it can last between three to seven years.
                                • What is roof cement used for?
                                  Working like an adhesive to repair holes and leaks in roofing systems, roof cement is a multi-purpose material. Roofing cement is generally comprised of different types of materials.
