Licensed Roofer Serving Johnstown, CO

"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. Glen Haven Roofing & Maintenance is one of the few local companies that can even offer it."

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."
