What our clients say about us

Terry - Calgary

FRG installed a new flat roof system on our commercial development (new built) in NE Calgary.

It was great working with them, they were good in communicating with the envelop engineer and the architect every step of the way to ensure the thermal envelop would tie in properly from the roof to the wall system. This was a good experience and quite different from what we had seen on other projects in the past. They were fast and effective.

Paul - Calgary

Fast and Professional – kept a extremely clean work site – did a complete tear off and re-roof in two days and protected landscaping and awnings – highly recommended.

Aldo Sierra, Calgary

I had a flat roof that had seen better days. FRG’s team did a great job restoring the whole thing and I’m very pleased. Definitely a recommended roofer.

What Our Clients Have to Say About Us


“Really happy with the speed and service, they shoveled off my  roof Saturday after the snow and got it finished on Sunday as
they said they would. The foreman even came by the next day to do a walk around  with me and made sure I was happy before
they collected the final payment. They also accepted credit card for a payment method which made it much easier to afford.”

Devon M – Calgary, AB



” Advanced Level Roofing worked on my house and they did an amazing job protecting my flowers and my garden from the roofing debris falling off the roof. They went above and beyond and we are so thankful we found them.

Anna S – Calgary, AB



“Our roof and gutter replacement went smoothly. The tile and gutter choices matched our siding well. They provide extra protection measures for the roof. Everyone was professional and friendly from Mitch and Zafar as our initial contact, David, the Operations Contact, Lucas, the foreman on the roofing job and Joey for the gutter replacement.Advanced level roofing came and fixed my leaky eavestrough. Tom came and explained everything to me and the crew came and did exactly how he said. This company is very responsive and professional. Would highly recommend!!!”
