At Reliable Roofing, Siding & Windows, we are proud suppliers of VELUX skylights, which come with Clean, Quiet & Safe glass. This innovative product offers a smooth surface that disperses water evenly, which removes dirt more quickly and reduces water spots, providing a clear view that is easy to maintain. These skylights should still be periodically cleaned. Use a nonabrasive cleaner and soft cloth or chamois when you clean the interior – this helps keep your skylight sparkling. The exterior glass should be cleaned every couple of years – most window-cleaning companies have all the tools needed to reach those hard spots without needing access to your roof!
