I’ve had 4 roofers by recently after the recent weather who quoted $2,200 damage. I called Seth with Commonwealth Roofing, who inspected and stated our current roof was solid and in great condition, thank you Seth with Commonwealth Roofing who inspected! I’ll recommend you to all my clients. Kathy Ludwig, United Real Estate Louisville

Colin Masters is a wonderful, honest, fair and patient roofing consultant. He is an absolute pleasure to work with. A.J., the job manager, and his crew did a GREAT job! His crew worked extremely hard and it was done during the extreme heat wave we had. The clean-up after the job was finished was fast and timely. They were very quick with their follow-up to make sure that we were satisfied and if anything was needed. I highly recommend using Commonwealth Roofing!

I had a very pleasant and informative visit with Seth today. Besides being polite and professional, Seth is a wealth of knowledge when it comes to roofing. He made a quick assessment of my roof, and provided me with the information I needed. I really like the way Seth and Commonwealth Roofing Corp. do business. I will use them for my future needs. Thanks.

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.
