Manufactured skylights get a bad reputation by being associated with a common pool of items referred to as “skylights”. Sometimes, people build their own skylights. Some manufacturers also used to screw the corners of their skylight frame together, creating openings for moisture to penetrate. We only supply and install quality manufactured skylights that feature welded corners, approved flashing systems and frames with built-in condensation gutters to prevent leaking. We are experienced at properly installing quality systems, so that your skylight will bring you decades of natural light. Beginning in 2010, Velux introduced a No Leak Skylight with a 10-year installation warranty to demonstrate their confidence in their product.
