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
Dahm Brothers Roofing is highly regarded for their professional, high-quality workmanship and their commitment to leaving properties clean and tidy upon completion. Clients consistently praise the team for being responsive, honest, and easy to communicate with throughout the entire roofing process.
We had a roof replaced in Aug 2025. They gave the best quote and were very knowledgeable. They even sealed a roof leak we had before replacement since there was a wait in summer for the work to start. They arrived early 620a and were quick and tidy- finishing in one day before 530p and left the driveway and sidewalks cleaner than before. They also came back after to put in bathroom fan venting pipes in the attic. I would highly recommend!
Roof inspection and sealing vulnerable areas for leakage etc. We have been working with this company for many years. They never disappoint. They are always very responsive and friendly. They always complete the job that they have given you an estimate for.
Dahm Brothers Roofing is the only company that we would consider using when we have an issue. We have recommended to many friends and they are very pleased with the response time, quality work, professionalism knowledge and experience. We feel we are treated like family and that they truly care. Appreciate their integrity.
This was not a big job but we were treated wonderfully! I appreciate honest feedback on potential ideas that would not accomplish what I wanted. The gentleman who came to do the work did a part of the requested work but returned to complete the rest so the gutter would be the same. While on our roof, he repaired another issue he saw! You can trust these folks!
I am thrilled with my experience from start to finish. They were friendly, easy to communicate with, were thorough and fair in the quote process, and my roof looks amazing. I was pleased with the professionalism of the crew and how clean and respectful they were when on property.
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.
