Founded in 1951, IKO began as a small manufacturing plant in industrial Calgary. A family-owned enterprise, we made waterproofing materials the old-fashioned way: by soaking kraft paper with asphalt and by applying asphalt to paper-based felt.
There was an immediate demand for our products. With the post-World War II building boom, young families flocked to the suburbs to fulfill their dream of homeownership. We knew they deserved the very best roofing materials so just two years after opening, we introduced rolled roofing and later, asphalt shingles.
Customers loved our high-quality shingles. We expanded across Canada, continuously investing in our employees and technology to improve our products and modernize our business. By the late 1970's, our operations extended throughout Europe and the U.S.
Atlas shingles, as well as their limited warranties, are available in a variety of levels to accomodate each individual homeowner. Atlas limited warranties for asphalt shingles range from 30 Years on GlassMaster 3-Tabs up to a Lifetime Limited Warranty on the Pinnacle and StormMaster product lines.
Atlas also offers homeowners the option to upgrade to the Atlas Signature Select® Roofing System where you will receive increased premium protection coverage for your roof when you choose to install qualifying Atlas shingle accessories and underlayments. If you are interested in the best warranty for your new roof, ask us about Atlas Signature Select.
