Roof repair & leak repair
A small drip left alone becomes structural damage, mould and costly interior repairs. We trace leaks to their true source and repair them without voiding your existing system warranty.
We find the real source, not just the stain
Water often enters at one point and travels ten feet down a rafter before it drips onto your ceiling. Our field-trained technicians use the right tools and five decades of experience to trace these "ghost leaks" back to their origin — cracked flashing around a chimney or skylight, worn or missing shingles, or ice damming along the eaves.
Because A & G is CertainTeed-certified, repairs are done in a way that keeps your existing system warranty intact, and every technician works with professional fall-arrest gear and strict safety protocols.
What our repair service covers
Common repairs we handle across the region:
How it gets booked
From my first phone call where I reached Violet, to Josh for the quote, then Glenn and his team on site — they arrived as scheduled, worked quickly and efficiently, noted and fixed problems with the adjacent siding, and cleaned up the site beautifully.
I owned a large high-end roofing company based in Toronto for 35 years. I chose A&G partly based on reviews, but also on the instant knowledge and credibility Josh and Adam portrayed. They did not disappoint.
We had three roofs done. Very professional. Showed up when they said they would. Explained everything as they worked. Cleaned up everything. The roofs look great.
Other roofing services
A & G also handles these across Orillia, Simcoe County and Muskoka.
Roof repairs questions
Look for discoloured "tea-coloured" rings or soft spots on ceilings and upper walls, bubbling paint near windows, or — in the attic during a storm — wet insulation and dark trails on the underside of the roof deck. On a sunny day with the attic lights off, pinpricks of daylight point to a hole.
Yes. If water is actively getting in, call (705) 325-1805 and we'll help you protect the home and book the repair as quickly as we can.
No. As a CertainTeed-certified contractor we make repairs the correct way so your existing system warranty stays valid — an independent handyman repair can put it at risk.
The #1 leak zones are flashing failures around chimneys, skylights and valleys, followed by the "northern culprit" — ice damming driven by freeze-thaw cycles in Orillia and Simcoe County.
