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.

We put engineering and state-of-the-art technology into every shingle. Although invisible to most people, roofing products have evolved dramatically. Approximately 25 years ago, fiberglass started becoming the shingle mat of choice. For select shingles, we modified our asphalt to make our shingles more pliable and durable. We added special granules to help protect roofs from the damage of UV light. And we introduced computer-aided color design to increase selection and enhance the beauty of our shingles.
