Which shingles are better, IKO or BP?

Deciding which shingles are better between IKO and BP depends on availability and region, as both are Canadian-founded brands with good value but different market strengths. IKO is a larger international manufacturer headquartered in Canada with plants in US, Canada, and Europe, known for Cambridge architectural shingles with ArmourZone nailing area and 130 mph wind warranty, and Dynasty with good color options. IKO costs around 80 to 120 dollars per square and offers lifetime limited warranty. IKO has faced some historical complaints about granule loss but modern Cambridge and Dynasty are improved. BP, which stands for Building Products of Canada, is owned by Saint-Gobain and is very popular in Canada and northern US, known for Mystique and Dakota architectural shingles with good durability and weather resistance for cold climates. BP shingles feature Weather-Tite technology and are known for good performance in harsh Canadian winters. BP costs similar to IKO at 80 to 120 dollars per square. In terms of quality, both are considered mid-tier value brands, slightly below premium GAF and Owens Corning in contractor surveys, but good for budget-conscious projects. IKO has larger distribution in US and more color options, while BP is stronger in Canada. For homeowners in Canada and northern climates, BP is often considered slightly better for cold weather flexibility. For US homeowners wanting wider availability, IKO is better. Both offer decent value for price.
