What Re-Roofing Is
Re-roofing installs a new layer over your existing roof, where the structure and deck allow it. It's quicker and less costly than a full tear-off — but it's only appropriate in the right conditions, and not on a roof that's already been layered.
Re-Roofing vs Full Replacement
We inspect the deck and existing layers and tell you honestly which makes sense. If there's hidden rot or multiple existing layers, a full replacement is the smarter long-term call — and we'll explain why.
Code, Weight and What an Overlay Hides
Alberta code generally allows two layers of shingles, and there are good reasons it stops there. A second layer adds weight the structure was not necessarily designed for, holds more heat which ages both layers faster, and hides the deck from inspection. An overlay done on the wrong roof buries problems that surface as leaks two winters later. That is why we check the deck, the existing layer and the attic before we will quote one.
