Calgary, AB Aluminum Shingles Review: 3 Years of Maintenance‑Free Interlock Roofing Installation Satisfaction

I did a lot of research prior to selecting Interlock roofing. There are an abundance of good roofing material on the market but I was looking for a very long term and maintenance free product. Interlock offered an excellent product and a great warranty.

Their installers showed up on time, were very professional and courteous, and did the job within the estimated time schedule and price. Before the job was even started a few things were pointed out which required some slight roof modifications and venting changes. This was explained to me in a very professional and understanding way. Any sections of underlying plywood which were not up to standard were also replaced at the agreed upon price. Before any changes were made I was shown the reason why and I gave approval prior to proceeding.

I am very happy with the installation and product and would definitely endorse an installation through Interlock. I waited 3 years before writing this review because I wanted to make sure everything worked properly without any call backs.
