How to Clean Roof Skylights

In most regions, roof skylights only require an occasional cleaning -- about once or twice a year. Some coastal regions may require more frequent cleaning due to higher amounts of airborne particles. Focus on cleaning the inside of the skylight since rain and snow should keep the exterior of most skylights clean. If the exterior of the skylight does need cleaned, apply the same method for cleaning the interior of the skylight to get the exterior clean. Following the cleaning guidelines recommended by most manufacturers should keep your roof skylights looking near new for years to come.

  1. 1

    Use a ladder or scaffolding to reach the skylights that need cleaned.

  2. 2

    Clean the skylights starting from the highest row and working your way down.

  3. 3

    Mix a few drops of a mild liquid detergent in a bucket of water and soak the skylight glass with the solution to loosen dirt.

  4. 4

    Spray a glass cleaner on the skylight glass. Wipe off the soap and water solution and the glass cleaner with a clean, lint-free cloth or squeegee.

  5. 5

    Wipe the wood frame with a damp cloth. Add a drop of detergent to remove dirt build-up.

  6. 6

    Remove the screens if your skylight has them. Spray the screens with a garden hose. Give the screens plenty of time to dry before replacing them in the windows.

Tips and warnings

  • Falls from roof level heights can cause serious injuries. Use fall protection and know your limits.
  • Do not use scrapers or blades for cleaning as they could scratch the glass.
  • Do not use abrasive cleaners on the glass or frame.
  • Avoid cleaning the skylights when hot.
