That's the second time I have called the company for a project, so it is because we are very happy with everything.

John and his crew did an amazing job on our roof. It looks absolutely outstanding. There was no cleanup after they cleaned everything up. They are very professional. They have an amazing warranty that is transferable. I highly recommend them.

I had additional snow guards installed on my Interlock Roofing Systems shingles. The work was done by Ken Moore. I have only praise to offer for the work this man did to my place. Sure, the product is good, but people like Ken make the company what it is: a reliable entity. I have had other less pleasant interactions with other people from the company, and, honestly, Ken's work confirmed that the human factor is important to a company's reputation. Kudos to Ken for a job well done.

Brad and Ken were out to replace some old skylights for us and install some new snow guards. They were very friendly and professional! The work took an extra day due to some severe inclement weather but we were not charged any additional fees beyond the quote which was appreciated! I would definitely have them back out for any future roofing issues and felt that they were extremely knowledgeable.

From start to finish Interlock Roofing exceeded our expectations. We have a steep roof with dormers/intricate angles and many roofers denied the job. We felt completely confident throughout the whole process that we chose the best type of roof for life on Georgian Bay. Bruce was incredible form beginning to end. The installation team, John Sr., John Jr. and CJ, were incredible. They made sure everything was cleaned up and organized daily. They worked from day to evening, no matter the weather to ensure the job was done in a timely matter. Highly recommend Interlock Roofing aluminum roofing!

Our contract with Interlock dates back to July 17/01. Ken was the first company representative that listened to us and promised to solve the leakage. His dedication to fixing the roof properly was very much appreciated.

I don't normally write reviews, but Interlock Roofing has earned an exception. Over the years, we have dealt with several roofing companies, and our experience with Interlock Roofing has been the best by far. Our roof is very complex, with numerous peaks and valleys, making it a challenging project. The team completed the installation with outstanding workmanship, and we have not had a single leak in the six years since the roof was installed. The customer service has been equally impressive. Bruce, our sales representative, has been exceptional—professional, knowledgeable, and always responsive whenever we have needed assistance. We highly recommend Interlock Roofing to anyone looking for quality workmanship and outstanding customer service. They have exceeded our expectations, and we are happy to give them a well-deserved five-star rating. ★★★★★ Wayne and Janet Ablitt

Thanks, Interlock! Bruce was a great help in understanding and selecting my options for the roof and Maurice was very patient in explaining any questions I had about the installation process. The whole team was a pleasure to interact with and I'm very pleased with the finished product.
