Skylight Roof Repair: A Comprehensive Guide to Fixing Leaks and Extending the Life of Your Skylight
Skylights are a great architectural design element that can let natural light into an otherwise dark room. However, because they penetrate the roof's surface, skylights can sometimes leak. Worn weatherstripping, holes around the flashing, and older skylights that have started to fail are all common causes of leaks.
- Worn weatherstripping
- Holes around the flashing
- Older skylights that have started to fail
Identifying the Cause of a Skylight Leak
If you notice a leak from your skylight, the first thing you need to do is identify the source of the leak. This can be done by inspecting the skylight frame, sash, and flashing around the unit.

- Inspect the skylight frame for cracks or damage
- Check the sash (the moving part of the skylight) for damage or faulty operation
- Examine the flashing around the skylight for gaps or damage

- Minor leaks can be fixed with caulk or sealant
- More significant leaks may require replacing the skylight seals or flashing
- If the leak is caused by a structural issue, it's best to call a professional
