ARCO Review Findings
Diamond Roofing is described as honest, communicative, and straightforward, particularly when assessing damage and working with insurance companies. Reviews also highlight fast, efficient workmanship, courteous crews, timely project completion, and thorough cleanup.
In late August 2025 baseball sized hail hit our neighborhood in the Black Hills. Homes and cars were damaged everywhere! Numerous roofing companies descended on the area, some of which were not honest. We had thousands of dollars worth of window damage. However, I felt that my impact resistant shingles did pretty well. I had one company come out, and the guy instantly said my roof, soffit, and siding were destroyed. He went as far as say he’d have to remove my soffit , and he was not sure about keeping the lighting. We had zero damage to any soffit or siding. A few days later, Ken and one of his business associates from Diamond Roofing came out and checked our roof for damage. After coming down from the roof, they told me that they were amazed at how little damage there was if any. It was their opinion that I did not need a new roof. I really appreciated the honesty. A few days later, USAA insurance sent out their catastrophic damage team. I did not tell them what Diamond Roofing had found. The insurance adjusters also agreed that my roof had a little to no damage. I can’t say enough about Diamond Roofing’s is honesty and integrity. No doubt who I’ll be choosing when it comes time to replace my roof.!!!! Ron Newquust
Great company. Quick service. They clean up well after repairs. Communication was great. I have worked with two other companies in the past 5 years and they have been the best by far. I will be calling again in the future!
They are awesome! Quick and efficient + they clean up well after! Highly recommend!
Diamond roofing was phenomenal to work with. We needed our roof replaced on our motel and we contacted them. Marilouise was the rep and we told her specifically what we wanted, concerns and time frame we needed it to be done. Her response was that it wouldn't be a problem. She was awesome to work with. Crew came in on a Saturday and was finished by Sunday. Fernando 's crew was great. Those guys were so nice and courteous. That also, worked their tails off. Plus, crew cleaned up after themselves. We couldn't tell they were ever here. Diamond roofing is a class act outfit that I recommend. Thank you, all!! Kari R Welsh Welsh's Motel Wall, SD
Diamond roofing has replaced roofs on two of my very large Skilled Nursing Facilities and managed the other subcontractors for us. They were very respectful to our residents and staff. The job was done timely with no issues. One of them was four hours away from Rapid City where we couldn’t find a local contractor that was responsible and reasonable to work with. I will use them going forward on any of my projects on the 27 buildings I run.
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.
