The first time you visit an IKO plant, it may surprise you; there are no big, flashy signs to advertise our presence. We are a company that is more interested in building our reputation one roof at a time rather than by bold advertising or self-promotion. But don’t mistake that ‘nose to the grindstone’ attitude for a lack of pride. We at IKO have a long history of innovation, quality products and customer satisfaction and employee commitment that we are very proud of. We also have a rich history of perseverance and will to be the best that is rooted in the remarkable story of our founder, Isidore Koschitzky.

In 1922, Mr. Koschitzky began his long career in the roofing industry at the age of 17, when he started to work as a salesman in his father’s roofing manufacturing business. Despite the challenging market, through Mr. Koschitzky’s resourcefulness and innovation, the company achieved great success and opened a second plant in Warsaw. By the early 1930’s, the company had come to prominence as the second largest manufacturer in the country. The invasion of Poland in 1939 resulted in not only the loss of his business, but much of his family as well.

Always the entrepreneur and innovator, Mr. Koschitzky founded IKO Industries in Calgary, Alberta in 1951. The company first manufactured building paper, and expanded to include coated roll roofing. The company made its first asphalt shingle in 1954, and the rest, as they say, is history.

The company thrived, first coming to eastern Canada with the opening of the Brampton, Ontario shingle plant in 1959. Success in Brampton led to further expansion, first into the European market with the construction of a shingle plant in Ham, Belgium in 1972, and further Canadian growth with a new facility in Hawkesbury, Ontario in 1976. IKO then joined the U.S. marketplace in 1979 through acquisitions and has since expanded by building new factories across North America. Today, more than 60 years after its founding, the company has grown to be among the world’s largest exporters of asphalt shingles.

The company is now a worldwide enterprise, with more than 3000 employees, and manufacturing plants in Canada, the United States, England, Belgium, Holland, France and Slovakia.
