What is the best brand of shingles in Canada?

The best brand of shingles in Canada depends on whether you prioritize Canadian manufacturing, premium technology, warranty, or best value for harsh winters, but top brands consistently include IKO, GAF, Owens Corning, BP, and CertainTeed. For best Canadian-made and overall value for Canadian winters, IKO is widely considered best, with IKO Dynasty and Cambridge manufactured in Brampton, Ontario, Canadian-owned since 1951, formulated with SBS modified asphalt for flexibility at minus 20 to minus 30 Celsius, ArmourZone technology for 130 mph wind resistance, and heavy mats for ice dam durability, plus supporting Canadian jobs. For best premium technology and North American market share, GAF Timberline HDZ and UHDZ are best-selling in North America with LayerLock, StainGuard Plus algae protection, and 130 mph wind warranty, though US-made. For best premium durability and SureNail technology, Owens Corning Duration is highly rated. For best budget Canadian-made, BP Building Products Mystique and Manoir made in LaSalle, Quebec by Saint-Gobain offer solid performance at lower price and are truly Canadian-made. CertainTeed Landmark Pro is also highly rated for color and durability. Most Canadian contractors rank IKO Dynasty as best for Canadian climate due to cold-weather flexibility and thick profile, GAF as best for warranty and algae resistance, and BP as best budget Canadian-made. For true Canadian-made quality, choose IKO or BP.
