Skylights are a great feature for Toronto homes with flat roofs. They bring in natural light, reduce energy costs, and add visual interest to the space. But when a skylight isn’t installed or maintained properly, it can become a major source of leaks. If you’ve noticed water stains, condensation, or dripping near your skylight, it may be time for a flat roof skylight repair.
At Flat Roof Toronto, we specialize in flat roof systems and understand the unique challenges that come with integrating skylights into low-slope or flat roofs. Unlike sloped roofs, flat roofs don’t naturally drain water away from skylights, which increases the risk of pooling, flashing failure, and long-term leaks.
Most leaks around skylights occur due to deteriorated flashing, cracked sealant, or separation between the skylight curb and roofing membrane. Over time, Toronto’s freeze-thaw cycles can cause these seals to contract and split. UV exposure can also degrade the plastic or glass materials, especially on older skylights installed more than 10 years ago.
Our repair process starts with a full flat roof inspection. We evaluate not only the skylight itself but also the surrounding roofing system, including the membrane, insulation, and drainage patterns. If the skylight is still structurally sound, we’ll reseal the perimeter, replace any worn flashing, and apply a new membrane layer around the unit for full waterproofing.
In some cases, skylight leaks are a symptom of broader roof deterioration, especially when combined with pooling water or sagging around the curb. In these situations, we may recommend a partial flat roof restoration to reinforce the area and prevent recurring problems.
For homeowners considering a skylight replacement, we can also help upgrade to a newer, energy-efficient model that improves insulation and reduces condensation. Modern skylights come with better seals, double glazing, and UV-resistant coatings that increase lifespan and reduce future maintenance needs.
We also ensure your drainage system supports the skylight. If water tends to pool nearby, we may modify the slope or add additional drainage features to keep water flowing off the roof surface. Good drainage is essential to preserving both the skylight and the surrounding roof area.
In conclusion, flat roof skylight repairs in Toronto require more than just caulking a leak. They demand proper sealing, membrane integration, and expert knowledge of flat roofing systems. If your skylight is leaking or showing signs of age, trust Flat Roof Toronto to repair it correctly—and protect your home for years to come.
