Pre-painted galvanized steel roofing does not have a defined end-of-life under normal conditions. It doesn’t granulate, rot, absorb water, or crack under freeze-thaw stress. The factory-applied paint coating carries a 40-year fade and chalk warranty on quality products.

In Gatineau’s climate, where rooftop temperatures swing from -30°C in January to +60°C on a July rooftop, this elasticity is the difference between a […]
