Roof Repairs & Installation in Vaughan

Water entering a roof does not fall straight down. It runs along the underside of the deck, follows a rafter, travels sideways across a ceiling, and appears somewhere that has nothing to do with the entry point. Which is why patching directly above the stain so often fails - the hole is elsewhere. Most GTA roof failures come from a short list. Shingles at the end of their service life curling and losing granules. Flashing that was never detailed correctly at a chimney, skylight, or roof-to-wall junction. Wind lifting a course along an exposed edge. Nail pops. And underneath all of it, poor attic ventilation cooking the shingles from below and shortening the life of the whole roof by years. Winter is a separate category. Heat escaping into an under-ventilated attic melts snow on the upper roof, the meltwater runs down to the cold eave and refreezes, and the resulting ice dam forces water backwards under the shingle course. Shingles are designed to shed water running down. They have no answer to water being pushed up. What starts as a small entry point becomes wet insulation, a rotting deck, and framing repair. The gap between a cheap fix and an expensive one is usually measured in how long it went unnoticed.
