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

"Second roof Cowiche Roofing & Maintenance has done for us. First one on our primary home, now our rental property. Same crew both times, same attention to detail. Drip edge, ice shield, everything by the book."

"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."

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Preston roof gets factory-level quality control.

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Preston homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.

21+ Years of Experience

We've been installing and repairing roofs for over 21 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.

No Subcontractors

Every Preston roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.
