What Orillia Homeowners Say
Trusted by Homeowners on Google
“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. To say I am happy with their service, and workmanship is not enough. If you need to have your roof done, please look no further, they will do an outstanding job.”
— Doug Ronson
“From my first phone call where I reached Violet, to Josh for the quote, then Glenn and his team on site doing the work, I was really impressed with the care and attention to detail everyone took. The team arrived as scheduled, worked quickly and efficiently, noted and fixed problems with the adjacent siding, and cleaned up the site beautifully.”
— Karen Burwell
“We had three roofs done. Very professional. Showed up when they said they would. Explained everything as they worked. Cleaned up everything. When finished you wouldn’t have known they were here. The roofs look great. We are very pleased with the workmanship.”
— Harry Alkema
“I am not in the habit of writing reviews but feel I need to after my experience with A&G Roofing. I owned a large high end roofing company based in Toronto for 35 years before it was sold, so I should know a thing or two about roofing! I chose A&G partly based on reviews, but also on the instant knowledge and credibility Josh and Adam portrayed.”
— Nick Mather
“Promptly on time, right on target with the estimate. Excellent workmanship and attention to detail. Site was cleaned up better than original. Thank you.”
— Stephen Grimes
“A big thank you to Adam and his team from A&G Roofing for coming out to repair the holes in our garage roof caused by the ice storm and replacing the shingles on our roof. They did an amazing job—professional, efficient, and high-quality work all around. We’re so grateful for their help and highly recommend them!”
