Can a skylight, roof window or sun tunnel leak?
VELUX skylights, roof windows and sun tunnels use flashing kits that are specific to roof pitch and roofing material. Provided the proper VELUX Flashing is used and installed correctly, we will stand behind the product against leaks for a period not shorter than defined in our guarantees. The unique construction of VELUX Skylights and flashings ensures safe drainage of rainwater coming from the roof above the window, providing complete weather tightness and preventing leakage. Because the roofing material covers both top and sides, VELUX flashings are largely unobtrusive. VELUX undertake extensive testing to ensure that all products perform to the very highest standards. VELUX Roof Windows, Skylights and flashings are put through some of the worlds most severe artificial rain and wind tests.
