About Us
In 1960, George Korellis began a residential roofing business out of his home. Since that time, Pete Korellis, current President and Owner of this second-generation business, with the help of many dedicated employees, has grown the business to encompass industrial and commercial sectors, with over 120 employees. Korellis Roofing continues to maintain the company's original core principles of honesty, integrity and customer satisfaction. By combining industry-leading talent, cutting-edge technology and award winning results, Korellis Roofing has earned a reputation as one of the premier roofing contractors in in the Chicagoland area, as well as the honor of being the largest roofing contractor in Northwest Indiana.

We are committed to surpassing customers' expectations while providing our customer with the highest quality and most current standards in the roofing and sheet metal industry - all at a reasonable price. We strive to attract and retain dedicated, professional and highly trained work associates by providing a safe work environment, which is conducive to learning, creativity, advancement and continuous improvement. We realize that by accomplishing the above, we have the greatest opportunity of creating long-term relationships not only with our external business customers, but also our internal associates, which is the core of Korellis Roofing, Inc.'s past and future business.

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.
