Karval Roofing Contractor | Serving Karval From Berthoud

"Hail punched through half our shingles last spring. Berthoud Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."

"Emergency tarping after a windstorm ripped our ridge cap off. Berthoud Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."

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

Free Inspections & Honest Estimates

We don't charge for inspections and we don't pad estimates. If your Karval roof needs a repair, we'll tell you. If it needs a replacement, we'll explain exactly why. No high-pressure sales, no scare tactics.

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 Karval 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 Karval homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.

No Subcontractors

Every Karval 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.
