Established in 1960, Korellis is a self-performing building envelope contractor specializing in roofing, sheet metal, wall panels, and masonry.
But being in business for over 60 years is only a small part of our overall experience. Korellis has installed millions of square feet of roofing and sheet metal 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 our various industries.
We are recognized as the premier roofing contractor in Northwest Indiana, and one the biggest in Chicagoland. We have worked at some of the largest steel mills and industrial locations in North America, as well as hundreds of churches, schools, government and office buildings, nuclear power plants and multi-million dollar *****s. We’ve completed projects with a wide variety of shapes, sizes and slopes and established safe environmental procedures during the removal and disposal of asbestos-containing roofing materials (ACRM).
Korellis’ real advantage comes from our team. Our office staff of employee-owners has a vested interest in the success of the business which means everyone from our Administrators to our Estimators to our Project Managers want to deliver the highest standards of customer service. Our field team members are highly-trained, union tradespeople getting paid great wages and benefits under their respective collective bargaining agreements. This investment in our employees amounts to an entire team with a stake in Korellis’ success – both short and long term.
