About ARCO Accreditation
Accreditation cannot be obtained through application alone. Each business must first undergo ARCO's complete review process and demonstrate that it meets the standards required for accreditation.
Provide your contact information below. ARCO will review your inquiry and determine whether your business may be invited to complete the accreditation review process.

ARCO Review Findings
Cloud9 Roofing is consistently praised for its professional, honest, and knowledgeable staff who provide clear communication and accurate project estimates. Customers frequently highlight the team's efficiency in completing work on time, their meticulous attention to detail, and their commitment to thorough job-site cleanup.
Tanner from Cloud9 provided great customer service! He was personable, knowledgeable and offered strong insight into what work was or wasn't needed for us. I appreciate Cloud9 being out in my community connecting with and offering services to current and potential clients!
Mathias with Cloud 9 was the most professional and knowledgeable of 3 roofing contractors that I met with. He was the only one to take care of all issues I had prior to signing a contract. The other guys were all about signing a contract and not doing what was necessary to take care of customer concerns. That would have left me liable for what they excluded from their proposal. Cloud9 was the only company who could provide a realistic quote without relying on an insurance company to provide it and address all the issues their competitors would not. They also showed up when they said they would and completed it in a timely manner. I highly recommend Cloud 9 Roofing.
We have had a wonderful experience with Cloud 9 Roofing! They were very patient and understanding while waiting on our insurance for our hail damage claim. Once we got them the deposit they were very quick to get us on the schedule for a new roof and gutters. Cameron kept up contact with us throughout the whole process to ensure we were 100% satisfied. The crew worked quickly and made sure everything was completely cleaned up before they left. 10/10 would recommend!
The process was fast and easy. They took care of everything and even went to the property when the insurance appraiser arrived. They explained everything clearly, and the contract was easy to understand. The work was estimated to take 2–3 days, but it was completed in just one day. Everything turned out great!
Mathias came out and inspected my roof damage the same day I contacted him. He immediately secured the area so I wasn't worried about further damage; and he got it patched and fixed the next business day. 10/10 would recommend!
Review data aggregated from public sources · ARCO does not moderate third-party reviews
The difference between "good enough" and proven excellence. Only the top roofers in America earn ARCO Accreditation — recognition of true craftsmanship, ethics, and integrity.
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.
