      NorthCan did a great job. It was done quickly and professionally and the clean up and waste removal was prompt and pristine. Was a pleasure dealing with Alex who was very patient with my lack of knowledge and many questions. Even though … More my job was small/residential they made it seem important to them and explained the different aspects of the project which gave me comfort that I have a long term, secure solution.

      I'm a property manager for several large commercial properties in Toronto. I've been dealing with Alex and NorthCan Roofing for several years and I only have good things to say about the company. We have had several instances … More where we have had to do complete roof replacements and emergency roof repairs and NorthCan has made the process that much easier. I would literally stress about leaks in my aging roof at night before using them but since I started dealing with them I no longer have to worry. Anything that has ever been patched has been perfect and no issues several years later with it. I would highly recommend them.
