Established over 60 years ago, IKO remains a family-run business, engaged in the manufacture and sale of asphalt roofing materials. It is a vertically integrated roofing company, producing many of the raw materials used in manufacturing its shingles, such as mineral stabilizer, roofing granules, fiberglass strands, and fiberglass mat. Most key components are manufactured within IKO’s family of companies, under its own stringent quality assurance. This provides superior quality assurance over all its finished products.
