MFM RidgeSeal™ (35 mil) provides a superior sealing barrier for use when installing concrete shingles and tile roofs. It eliminates costly and time-consuming mortar applications to critical hip and ridge areas where blowing rain can enter. The superb flexibility makes application proceed quickly, while the self-sealing qualities of RidgeSeal create an excellent weather- and insect-blocking barrier. And because of its strength, composition and durable UV-resistant surface, RidgeSeal can be left exposed after application, and prior to the installation being completed, for up to six months.
