Skylights are a beautiful feature in many Toronto homes, offering natural light and an open, airy feeling. But when they start leaking, they can quickly turn from an asset into a liability. Skylight leaks are more common than many homeowners realize—especially in climates like Toronto’s, where roofs endure snow, freezing temperatures, and spring rains. Knowing the causes and proper solutions is key to preventing water damage and maintaining your roof’s integrity.
One of the most common causes of skylight leaks is flashing failure. Flashing is the metal material installed around the skylight to seal the gap between the skylight frame and the roof. Over time, flashing can corrode, lift, or crack, particularly when exposed to Toronto’s freeze-thaw cycles. Once water finds its way beneath the flashing, it can seep into your attic or ceiling, often causing stains, mold, or peeling paint.
Another frequent issue is poor installation. If a skylight wasn’t installed correctly or was added after the original roof was built, it may not have the proper framing or sealing required to withstand weather exposure. Inadequate waterproofing around the base allows rain and snowmelt to creep in—often without immediate visible signs.
Sometimes the skylight itself is to blame. Cracks in the skylight glass, broken seals, or a warped frame can all lead to leaks. Even condensation trapped between skylight panes may indicate that the seal has failed. These issues often go unnoticed until water damage appears inside the home.
At Roof Repair Toronto, we specialize in locating and fixing skylight leaks with precision. Whether the leak is caused by flashing, roofing materials, or the skylight unit itself, we assess the entire area and determine the most effective solution. In many cases, we can repair the issue without replacing the entire skylight, saving you time and money.
We also handle leaks involving skylights on flat roof systems, which require special attention. Water tends to pool around skylight curbs on flat roofs, making the installation more vulnerable to leaks.
We proudly serve homes across the Toronto roof repair area, working on everything from small bungalow skylights to large custom glass panels in modern homes. Our goal is always the same: stop the leak quickly, protect your interior, and ensure your skylight is both functional and leak-free.
In conclusion, skylights add beauty and value to a home, but they also demand careful maintenance and professional repair when leaks occur. Whether you see water stains, dripping, or signs of mold near your skylight, don’t wait to take action. For dependable skylight leak repair in Toronto, trust the experts at Roof Repair Toronto to identify the problem and provide a long-lasting fix.
