Experience

Being in business since 1960 is only a small part of our overall experience. Korellis has installed millions of square feet of roofing systems. Under difficult conditions, often on projects with structural deck replacements, severe slopes, and poor logistics, work has been completed cost effectively and safely, while at the same time achieving some of the highest honors in the roofing industry.

We have worked at some of the largest steel mills in North America, as well as hundreds of churches, schools, government and office buildings, nuclear power plant and multi-million dollar casinos on Lake Michigan. We’ve completed roofs with a wide variety of shapes, sizes and slopes; used time-tested materials; and established safe environmental procedures during the removal and disposal of asbestos-containing roofing materials (ACRM).

But, Korellis’ real advantage comes from staying on the cutting edge of roofing technology. We keep on top of the new product research and select tested, state-of-the-art materials to add longer life and cost savings to your project.
