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.

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.
