Professional Roofing Services in Sonoma

"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."

"Our flat roof on the garage had been patched five times by other companies. Knightsen Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

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

GAF Master Elite Certified

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