I live in the Kawartha. Alpha is out if North York. Very happy I found them. I have a 1600sft roof that needed replacing. I found that they also do Skylights so I had them install a 4ft X 4ft Sky light. Incredibly efficient and professional. Echo, the project manager was very kind and made sure I understood what was happening and answered all my questions. She and the team did great work and completed the job in just 1 day and finished just after it got dark. I highly recommend this team. ??

Few weeks back ( September 9,2025), we had the good fortune of having Alpha Roofing replace our roof and we could not be happier with the results. From the very first meeting with Sandy, we were highly impressed. Sandy is very committed to his work, explained everything in detail, easy to deal with and professional. On the agreed date of installation, higly skilled professionals came and attended their tasks with thorougness and efficiency. They completed the work on the same as agreed. They disposed all the relative debris and with no damage to our property, specially the newly installed interlock. I want to say a big and special thank you to Sandy for going above and beyond to see that all our requests were satisfied and that I would have a pleasant experience. Sandy even came by during the installation to check with us that if we have any concerns or questions. We only had to pay at the end of the installation after everything was completed. Our neighbours stopped by and very impressed to see the work and we shared Sandy's contact to four of our neighbours. Two of them already signed an agreement and Sandy and his team are installing the roof for them. We would not hesitate to recommend Alpha Roofing for your next roof replacemnt project. Sandy, thank you again for all what you did for us. Pushpa

We needed to replace our old roof with a new metal roof and had heard great things about Alpha Roofing. Alan came out to assess the situation, and the whole process was straightforward and transparent. He clearly explained the benefits of a metal roof and how the installation would work. Their quote was competitive, and based on their solid reputation, I expected quality workmanship—and they definitely delivered. The attention to detail was impressive, and everyone from the installers to the office staff was friendly and professional. I’m very happy with how my new metal roof turned out.
