Many Vaughan homeowners see moisture near their skylight and assume it’s a leak. However, not all water problems are the same. Sometimes what appears to be a leak is actually condensation caused by temperature differences. Knowing the difference between condensation and leaks helps you avoid unnecessary repairs and ensures the right solution is applied.
What Is Skylight Condensation?
Condensation occurs when warm, moist air from inside the home meets the cold surface of the skylight glass. In winter, this is especially common in Vaughan homes. Condensation may drip down walls or collect on window frames, making it look like a leak. However, the issue often lies in ventilation rather than the skylight itself.
How to Identify a Leak
Leaks usually leave water stains, peeling paint, or damp drywall near the skylight. Unlike condensation, leaks continue even when humidity is low. They may also worsen after heavy rain or snow. Professional roof leak repair inspections can determine whether the issue is water seeping through the roof or just indoor humidity.
Common Causes of Leaks
Leaks typically result from cracked flashing, missing shingles, or worn seals around the skylight. On shingle roofs, leaks often occur when shingles near the skylight are lifted by wind. On flat roof systems, pooling water is usually to blame. In some cases, clogged eavestroughs push water back onto the roof, increasing the risk of skylight leaks.
Solutions for Condensation
If condensation is the problem, solutions focus on ventilation rather than roof repairs. Homeowners can reduce indoor humidity with dehumidifiers, bathroom fans, or by adding more insulation around skylights. Skylights with double-pane or energy-efficient glass also resist condensation better.
When Professional Repairs Are Needed
If moisture is due to actual leaks, professional skylight repair is the only long-term solution. Contractors will inspect flashing, roofing materials, and seals, then make the necessary repairs. In urgent cases, emergency roof repair services are available to prevent further water damage.
Final Thoughts
Condensation and leaks may look similar, but the solutions are very different. By learning to spot the signs and relying on professional inspections, Vaughan homeowners can protect their skylights from unnecessary repairs. Addressing the right problem ensures lasting results and keeps your home safe and dry.
