Residential roofing image

For over 50 years, A&G Roofing has been Simcoe County and Muskoka’s premier residential roofing contractor. Whether you’re looking for asphalt shingles, steel roofing, cedar or composite shake we can help you choose the right product for your needs and your budget.

Commercial roofing image

We design, install and service a wide variety of roofing systems for commercial and industrial applications. We have worked closely with architects, engineers and general contractors on a variety of projects encompassing countless design specifications.

Pine Grove Veterinary Hospital just received a face lift with a beautiful new roof installed by A&G Roofing.  The crew was an absolute pleasure to have; they were hard working, very friendly, professional and clearly worked with safety top of mind, both for themselves and for others who were in close proximity during the installation.  Communication was excellent, keeping us in the loop during every step of the process.  Things were cleaned up really well at the end of each workday and when the roof was finished, they performed a thorough walk-around to ensure all nails and other debris were cleared away.

A&G Roofing went above-and-beyond to ensure we were 100% happy with the work they did at Pine Grove Veterinary Hospital.  We will definitely use them again for any future roofing needs and recommend them highly to anyone needing roofing services.  Many thanks Brian, Carlston and everyone at A&G Roofing who contributed to this incredible experience.

- Dale Walsh

Absolutely fantastic customer service. Came right over and dealt with the issue we first called about and again to help us with other unrelated concerns we had, and spent over an hour and a half of his time to help resolve all of them. Without charging us for any of that time. Professional, friendly, and exceptional customer service. And the price was more than just competitive.

- Mike Marquardt

Highly recommend. They communicated in a timely manner and were very professional from the quote stage right through to the completion of the job. Thoroughly cleaned up after each visit. We are very happy with their work.

- Paul Haskell

The staff at A&G were friendly and helpful, from first contact to final inspection. They went out of their way to ensure a professional job, and thoroughly cleaned the area around the house after. They did a beautiful job, which they proudly stand behind. I heartily recommend them.
