Tips for Fixing a Leaking Skylight
On a clear day, a skylight fills your home with sunlight, creating a bright and inviting space. But when it rains, your skylight should never let water inside. A leaking skylight may signal water collecting around the frame, which can rot roof decking and cause costly structural damage. For reliable skylight repair and leak detection, Toronto homeowners trust The Roof Whisperer to deliver expert service and long-term protection.
Pinpoint the Source of the Leak
When water drips from a skylight, first place a container beneath it to protect flooring and furniture. Next, determine where the drip starts. A sturdy step ladder and indoor inspection often help locate the issue. Always use proper ladder safety, including a spotter.
Condensation
Check the skylight glass for condensation. Moisture often collects, drips, and mimics leaks. The best fix is improved ventilation. If the skylight doesn’t open, use a fan to circulate air. Clear any clogged weep holes outside to help moisture drain naturally.
Faulty Skylight
If the skylight opens, inspect the rubber gasket for cracks, mold, or wear. A damaged gasket won’t seal, letting in moisture. Remove debris around the frame that may prevent closing. Cracks in the skylight itself often require replacement for a lasting seal.
Faulty Roof Flashing
If the skylight is sound, the issue may be faulty roof flashing. Water often seeps beneath flashing or through poor seals. Leaks from the upper frame are easier to diagnose, while lower-frame leaks can be harder to trace.
Reseal the Flashing
If damaged flashing is confirmed, reseal it with high-quality skylight flashing sealant. First, remove old, cracked material with a putty knife. Then, apply fresh sealant generously along all flashing edges, especially at the skylight’s head. Lift shingles carefully if needed for full coverage.
When to Reinstall the Flashing
Sometimes, flashing must be replaced entirely. Improper installation—like nailing flashing directly to the roof—creates future leaks. Look for rust, gaps, or missing step flashing pieces. If these are found, a complete reinstall may be necessary. Step flashing ensures water flows away safely.
Because flashing replacement is complex, hiring a professional roofing contractor is strongly recommended. Proper installation ensures watertight protection and often includes warranties. Attempting it yourself can lead to more leaks and higher repair costs later.
Conclusion
Regular skylight maintenance and quick leak repairs protect both your roof and your home. Some issues, like condensation or gasket wear, may be simple fixes. Others, like flashing replacement, demand professional expertise. Acting early prevents major water damage and saves money.
