Licensed Roofer Serving Maddock, ND

"Emergency tarping after a windstorm ripped our ridge cap off. Portland 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 Portland Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."

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

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 Maddock roof gets factory-level quality control.

Free Inspections & Honest Estimates

We don't charge for inspections and we don't pad estimates. If your Maddock 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.

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Maddock 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 Maddock 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.
