Common questions about roof leak repair in Ontario.
We use a combination of visual inspection, water testing, and infrared scanning to trace the leak to its exact source. Leaks often travel far from where water appears inside, so professional detection is critical for a permanent fix.
In Ontario, the most frequent leak causes are damaged or missing flashing, cracked pipe boots, deteriorated shingle seals, clogged gutters causing ice dams, and improperly sealed skylights or vents. Our inspection identifies the exact cause.
Leak repair in Ontario typically costs $300 to $1,500 depending on the source and severity. Simple flashing repairs are on the lower end, while leaks requiring deck or structural repair cost more. We provide a free estimate before starting work.
Temporary measures can sometimes be applied from inside, but permanent repair almost always requires work on the exterior roof surface. We trace the leak path from inside the attic to find the entry point, then fix it properly from the outside.
Honest reviews from homeowners who chose Roof Angels for their roofing needs.
"Roof Angels replaced our roof and the difference is night and day. Better ventilation, no more ice dam issues, and the CertainTeed Landmark shingles have a beautiful profile. Worth every penny."
"Solid work on our commercial flat roof. The TPO membrane looks great and they handled the drainage issue that had been causing ponding for years. Would hire again."
"Bought a home and wanted the roof checked independently. Roof Angels found deteriorating pipe boots and compromised flashing that the home inspector missed entirely. Saved us from a future headache."
