Byron Roofing, unlike their competitor for our roofing job, showed up on time and gave us a favourable quote. Jon was professional at all times. We were told the new roof would be completed during the May to June time period They emailed us on May 52026 to advise the work would commence the next day, which it did. In two days we had a new roof as quoted. On time and on budget. The clean up was very thorough. We would most highly recommend Byron and Jon. Derek and Chauna.

GAF Timberline® shingles are our premier choice — we use them about 90% of the time, in colours like Charcoal, Weathered Wood and Pewter Gray. If you’d like a specific shingle, we’ll install that for you.
Snow melts on the roof, runs down and refreezes at the edge, forming a dam. Water then pools behind it and can back up under your shingles. More often than not, improper ventilation is the cause.
