VELUX solar powered "Fresh Air" Skylights do not require any wiring and are eligible for a 30% federal tax credit. This makes them highly affordable for your home. In fact, they even come with a 10-year "No Leak" installation warranty when you use EDL C06 flashing on a shingle roof with a pitch between 14-85 degrees, EDW C12 on a tile roof, or EDM C08 on a metal roof (flashing kits sold separately). These skylights feature Clean, Quiet and Safe LowE3 laminated glass with a Neat glass coating, keeping it cleaner and reducing outside noise. Plus, the laminated glass comes with a 10-year hail warranty for added safety, as required by building codes for out of reach applications. You can easily control the skylight with the included remote and insect screen, and don't forget to order the appropriate flashing kit for your roof type.
