Repairing Skylight Leaks in Toronto Roofs

Skylights are a great way to bring natural light into your home, but when they start to leak, they can cause a lot more harm than good. In Toronto’s changing climate—where snow, ice, rain, and fluctuating temperatures are common—skylight leaks are a frequent issue. Whether the leak comes from the glass, the frame, or the surrounding flashing, acting quickly is the key to preventing water damage and costly repairs.

One of the most common reasons skylights leak is flashing failure. Flashing is the material that seals the space between your roof and the skylight frame. If this flashing cracks, lifts, or separates—often due to weather exposure or aging materials—water can easily enter your home. This is especially common during spring thaws or summer rainstorms in Toronto, when flashing expansion and contraction can weaken the seal over time.

Another issue is poor installation. If the skylight wasn’t installed level or sealed properly in the first place, it may start leaking shortly after heavy weather exposure. Improper sealing around the curb or frame allows water to seep in around the glass and into your ceiling or drywall. Many Toronto homes have older skylights that were installed decades ago and are now showing their age, especially if they were added without updating surrounding roof sections.

Sometimes, the issue isn’t with the skylight at all—it’s the roof around it. If shingles or flat roofing materials are cracked or missing near the skylight, water may pool and find its way inside. This can be a hidden leak that appears far from the actual point of entry, making it difficult for homeowners to identify the true source without a professional inspection.
