Warner Commercial Roofing, LLC, founded by Steve Warner in 1997, is a family owned and operated company with deep roots in Northeast Wisconsin. Steve began his career in roofing under the tutelage of his father and soon ventured out on his own.

We have over 30 years installing Duro-Last commercial roof systems. Each roof is custom fabricated to fit your roof which reduces seams, waste, and saves on labor. Duro-Last is the most environmentally friendly roofing material and has one of the best warranties in the industry.

Steve has built a team of master craftsmen around him to continue and expand the impact on small and medium business. Nevertheless, he is personally involved in every install to assure 100% customer satisfaction.

The purpose behind our pursuit of excellence is defined as “Raise the Roof!” We are committed to elevating the roofing industry, the reputation of roofers, and those alongside us to better heights.

We proudly invest our time and talent in mission-based projects in Northeast Wisconsin, Mexico, Haiti, and Costa Rica.
