Product Information
VELUX ECW curb mount flashing is designed to work with tiles (over 1/2 in. thickness) and other high-profile roofing materials. The flashing is pliable and pleated, making it easy to form the flashing to the roof tiles. It includes an adhesive underlayment that provides an additional layer of water protection and prevents leaks. When paired with the VELUX No Leak Skylight (models FCM, VCM, VCE, VCS) this flashing makes the skylight eligible for the VELUX 10-year installation warranty.
