Why the No Leak Skylight?

The no leak skylight logo

With our most advanced line of skylights, we promise you no leaks, no worries and we back it up with an industry first 10 year installation warranty. The No Leak skylight line offers 3 layers of water protection with all these deck mounted skylights and associated flashing systems. First, VELUX introduces a third layer of water protection in the pre-attached deck seal that provides a seal between the frame and roof deck for a leak-proof installation. Second, an adhesive underlayment provides secondary water protection against the harshest weather conditions. Third, VELUX offers engineered flashing for easy installation and primary water protection on a full range of roof materials. See the warranty brochure for additional details on our product and installation warranties.
