Toronto, ON Aluminum Shingles: Expert Interlock Roof Installation Review and Lasting Wind-Resistant Performance

It was easy to talk to and work with all of the knowledgeable people at Interlock. Before we committed to go with Interlock, we looked at several roofs in the area that had Interlock installed (using Google street view, due to a COVID-19 stay-at-home order); they all looked great.

Tony started the installation work on April 5, 2021 and completed it on April 14, taking about 7 days of work. It took this long since Tony did all of the work himself, but at least he is a highly trained person (for over 30 years) making sure all of the work is done properly. Before he started, Tony discussed a few details with me to clarify exactly the method to be used, such as how to seal around two brick chimneys and how to fit the roof edge to the covered eaves troughs. The Interlock system was installed over top of one layer of old shingles. The Interlock tiles are held down with nails that have rings around them, so they will hold like screws. The Interlock tiles are mechanically locked in to each other on all four sides, so I don’t expect any future problems with any wind damage. Everything looks great. Hopefully the surface will now discourage the racoons from going on the roof (and leaving their excrement).
