Licensed Roofer Serving Concord, IL

"We went with the Owens Corning Duration shingles in Driftwood. The ridge vent and intake ventilation they installed dropped our attic temperature noticeably. Energy bill went down that first summer."

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Harmon Roofing & Maintenance is one of the few local companies that can even offer it."

"We got three quotes for a full tear-off and Harmon Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."
