Residential roofing products
We install the full range of systems and help you match the right one to your home, climate and budget.
Steel & standing seam metal
Classic styling, low maintenance and lifetime performance in a wide range of profiles. Built to shed heavy snow and stand up to the freeze-thaw cycles of central Ontario.
Composite shake & slate
Euroshield and similar composites give the true-to-life look of slate or cedar with the resilience of up to 95% recycled rubber — hail-tough and virtually maintenance-free.
Residential low slope
For roof sections below a 2-in-12 pitch we install commercial-grade membrane systems (EPDM/TPO) engineered to stay watertight where shingles cannot.
Cedar shake & shingles
A natural, rustic choice with real character. We guide you through the differences in grades, styles and accents so the roof matches the home.
From the quote to the installation, A&G Roofing was outstanding. They even helped me out with my deck design that was to be put on top of the new flat roof. If you need to have your roof done, please look no further — they will do an outstanding job.
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.
Roofing service questions
Check the roof's age and visible damage — large patches of missing shingles, widespread curling or sagging, granules collecting in the gutters like sand, or moss over large areas point toward replacement. As a rule of thumb, if a repair would cost 30–50% of a new roof, replacement is the smarter long-term investment.
A standing seam steel roof generally starts at roughly double the cost of an asphalt roof, varying with the scope and architectural complexity of the home.
Yes — full manufacturer warranties on all materials plus A & G's own 10-year workmanship warranty on the installation.
A standard asphalt shingle roof on most homes takes 1–3 days; larger or more complex roofs 3–5 days; premium metal, cedar or composite systems 5–10+ days.
Start with your climate needs and budget, then weigh lifespan against cost and maintenance. Remember installation quality matters more than the material itself — we'll walk you through the options.
