  Called for a quote, said they were going to come weeks ago but won’t even return our phone calls now. Not very professional. Going to go with someone who actually answers their phone and customers.

  The Admin staff gave me a date of either Wed or Thurs when I contacted them on the Sat following the Friday wind storm to replace all the shingles lost. I re-contacted them again Wed morning to get an update, and was asked if there was plywood showing and how extensive the shingle loss was. There was plywood exposed and the shingle loss was extensive.The lady then kindly said she would make sure a team was there that day to do the repair in view of the rain storm predicted for that evening. Got home that evening, nothing was done. Contacted the company and left a voicemail. Then had to spend $50 at Home Depot getting a roll of plastic sheeting and spend the rest of the evening laying it down in my loft to protect my bedroom ceilings in case the water came through the plywood. Received a call back early the next morning apologizing the work was not done, then got a follow up call 30 mins later insisting the work had been done and they had photos to prove it and I would be getting a bill for it! Later that morning received a text saying they got the numbers on my street mixed up (even though I had stated my number clearly several times to them) and I would not be billed.Somebody on my street will be getting a bill they were not expecting. I would not recommend using this company in view of the experience I have had.

  Did my previous house , nice job on roof but someone leaned a latter against eavstrough right above front door and did some damage! Got a quote to do my new house from blueprints supplied by me and ended up almost double from quote. Blamed me for changes to plans but there were no changes. BEWARE IF YOUR USING PLANS!

  Rob was very nice and told us what had to be done and will send a quote. Was scammed by a company named Canadian Roof Repair and Masonary for $10,340.

  Rob and Michelle have been amazing . Rob and team installed some new downspouts and they were quick and efficient. It was a small job but was nice that when I called someone always answered and Rob even met with me the same day. Great business owner and i highly recommend for any roofing job. Thanks!

  We had a roof installed through sears in 2008. Many of the shingles started to curl. Sears gave us enough money from warranty that we were able to get a new roof in 2011 that is still in great shape as of 2025. …

• 5 out of 5Sheena Griffitha year ago

  Rob inspected my roof and assured me that after 10 years, nothing needed to be done or improved, contrary to another roofer who knocked on my door to inform me that he could see a hole in my roof ! He is honest and trustworthy.

  Excellent job redoing our roof. Very professional and also extremely helpful in identifying and solving the water damage problem in our sunroom. They went above and beyond in arranging a spray foam insulation installer and drywall contractor to get the repair work done. Rob took the time to fully explain the cause of the problem (condensation from improper air circulation in the attic) and how to correct the situation. I fully recommend this company!
