Is IKO shingles a good brand?

IKO shingles are considered a decent to good brand for value-conscious homeowners, offering competitive pricing and good features, though rated slightly below premium brands like GAF and Owens Corning in contractor surveys. IKO is a large international manufacturer founded in Canada in 1951, with plants in US, Canada, and Europe, and offers Cambridge as its flagship architectural shingle with dual-layer construction, many color options, and ArmourZone technology that provides a wider reinforced nailing area for improved fastening accuracy and 130 mph wind warranty when installed with 6 nails. IKO Dynasty offers similar features with enhanced shadow lines. IKO shingles cost around 80 to 120 dollars per square for materials, which is 10 to 20 percent cheaper than GAF Timberline HDZ and Owens Corning Duration, making them attractive for budget projects. Warranty includes lifetime limited warranty defined as 50 years and 10-year algae warranty. IKO also offers designer lines like Crowne Slate and ArmourShake that mimic slate and wood shake. While IKO had historical issues with organic mat shingles in the 1990s that led to lawsuits, modern fiberglass mat shingles are improved and considered decent quality. For homeowners on tight budget or rental properties, IKO is a good value brand, but for homeowners wanting best long-term track record and largest contractor network, GAF and Owens Corning are often preferred.
