IKO opened it’s first shingle plant in 1959 in Brampton, Ontario an Eastern part of Canada. They are truly a global company shipping to at least 94 countries worldwide.
Vertically Integrated Manufacturing:
Unlike some of their main competitors IKO believes in controlling personally the raw products that go into their shingles. They have quarries for limestone/granule production. Plants that make fiberglass and the matting. Even printing the labels is in house.
They’ve branched out over the year as far as the style of shingles offered and now have a good gambit of offerings. Shingles from IKO are cut slightly different reveal lines than other manufacturer’s which make them easier to pick out.
They also offer value price point for many products so gather some attention from cost conscious consumers and contractors.
Lower than average ratings and reviews
Overall consumer confidence is lower than we see from Owens Corning, GAF, and Certainteed. Like many manufacturers of asphalt based roof shingles they’ve been involved in class action lawsuits regarding a shingle line no longer produced.
