ARCO Review Findings
Nimbus Roofing and Sheet Metal is consistently praised for their professional, knowledgeable, and responsive approach to both residential and commercial roofing projects. Clients frequently highlight the team’s ability to efficiently solve complex roofing issues, maintain clean job sites, and provide high-quality workmanship at a fair price.
This review is for a commercial roof of a medical building. Nathan and his team made the replacement process so easy for us. We replaced a 40ton HVAC Unit at the same time he was replacing the roof and he made it appear so effortless on his end. Even our HVAC team has since complimented the new roof and sent me photos of it. While Nimbus was on-site, I didn't receive a single complaint from any of my tenants, which is unheard of in a medical facility. HIGHLY recommend.
I have worked with Sam and Nathan on a few projects, and they are extremely knowledgeable when it comes to flat roofing. It is difficult to find an honest flat roofing contractor that will work on smaller projects, and these guys are top notch. I will continue to work with them in the future, and can't recommend them enough.
Nathan and his team at Nimbus Roofing did a great job on my small garage roof. Everyone was very professional and worked with my schedule and particular details of my roof. Would highly recommend them for any roofing job you might have. Have already told a number of my neighbors of their work.
Contracted with Nimbus to correct flat roof over my garage. Sam and his crew came out and reassured me they could correct. They completed the job in one day and roof looks great; no puddling of water. Crew was professional and clean; no debris left on property. Price was very acceptable. Definitely recommend this contractor. Thank you, Nimbus!
We really lucked out with Nimbus Roofing and Sheetmetal. They were not only a great value, but we’re also very professional, fast and attentive to any concerns we had when they were done. Getting a new roof can be extremely stressful, but the whole experience with Nimbus was stress-free and we are extremely happy with the experience. If you are thinking about getting a new roof, I would seriously recommend giving these guys a call!
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.
