Roof replacement & new-roof installation
When a roof reaches the end of its life, we remove it to the deck and install a new system engineered for Ontario winters — for homes, cottages and businesses across Orillia, Simcoe County and Muskoka.
When it's time for a new roof
Roof replacement means removing your existing roof down to the deck and installing a new one. It's the right call when a roof has reached the end of its life, or when damage has grown beyond what repairs can stay ahead of — large patches of missing shingles, widespread curling or sagging, or granules collecting in the gutters like sand.
A & G handles new builds and full replacements in asphalt and architectural shingles, standing seam metal, Euroshield composite and cedar. Every roof is installed with proper ice-and-water protection and ventilation designed for snow-heavy regions, then documented in CompanyCam so you can see the parts that end up hidden under the shingles.
What a roof replacement covers
Every replacement is scoped on site. In general the work includes:
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.

A & G also handles these across Orillia, Simcoe County and Muskoka.
Roof replacement questions
As a rule of thumb, if a repair would cost 30–50% of a new roof, replacement is usually the smarter long-term investment. Send your address and a few details, or call (705) 325-1805, and we'll assess the roof and recommend the right path.
A standard asphalt shingle roof on most homes takes 1–3 days; larger or more complex roofs take 3–5 days; premium materials like metal, cedar or composite typically run 5–10+ days.
A full manufacturer's warranty on all materials plus A & G's own 10-year workmanship warranty on the installation.
Start with your climate needs and budget range, then weigh lifespan against cost and maintenance. A quick tip: installation quality matters more than the material — a poorly installed premium roof fails faster than a well-installed basic one.
