William was great to work with. I ran into a snag on the front end but William was very communicative and tried to be as helpful as possible. Work was done quickly and professionally, and looks great.

I had a "repaired" leak in my roof and the leak remained. My friend referred me to Patterson Roofing (after many weeks of trying to reach the original installer of my roof with ABSOLUTELY NO response). I was able to quickly get an estimate and the work was completed soon after. Timely responses and direct communication. If you need any roof work done, I highly recommend Patterson Roofing!

William was great to work with. Every part of the process he was thorough and helpful answering all the questions I would have. Had some work done on the patio roof due to some water damage and rotten wood that needed to be addressed. William even came back and did some final touches after the job was completed too. Highly recommended! Thank you again so much!

This was one of the smoothest contractor experiences we've had. Communication was clear, scheduling was reliable, and the crew consistently showed professionalism. They completed the project within the promised timeframe and left the property remarkably clean. The new roof looks fantastic and gives us real peace of mind.

Why Hire an ARCO-Accredited Roofer

The difference between "good enough" and proven excellence. Only the top roofers in America earn ARCO Accreditation — recognition of true craftsmanship, ethics, and integrity.

Homeowner Benefits

Peace of Mind: Every ARCO-Accredited roofer has been checked against public licensing records, safety records, complaint history, and verified customer reviews.
Work You Can Trust: ARCO's evaluation includes manufacturer certification programs — credentials that can help preserve your roof's warranty coverage.
Verified, Not Self-Reported: ARCO's findings come from government and third-party sources — state filing offices, SAM.gov, OSHA, and the BBB — not from paperwork a contractor submits about itself.
A Public Paper Trail: Every accredited profile publishes its report number, evaluation date, and sources — so any homeowner can independently verify the findings at RoofingContractors.org.
