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.

- Examine the flashing around the skylight for gaps or damage
