IKO is among the top vertically-integrated manufacturers in its industry, making almost every major component that goes into its roofing shingles and related roofing products.

IKO’s self-reliance on supplying most of its own materials means it is able to control its quality in a way very few competitors can match.

An IKO-owned plant in Barrie, Ontario, extrudes and prints the plastic wrappers that protect every plant’s finished shingles in transit.

IKO also oxidizes its own weathering asphalt; almost 200,000 tons of asphalt flux are stored at IKO plants. IKO quarries and crushes its own limestone, colors its own granules and make its own back surfacing at a variety of locations across North America.
