How ARCO Evaluates Roofing Contractors
How evaluations are conducted
Records first. Then a finding.
ARCO does not accept applications, payments, or self-reported attestations at the evaluation stage. Findings are produced from public records and third-party data, scored against the published standard, and stored for verification.
Step 01
Public-record collection.
State filings, SOS records, OSHA establishment data, the SAM.gov extract, and consumer-platform and rating aggregates.
Step 02
Data verification.
Each data point is reconciled against its primary source and timestamped. Anything unverified is not scored.
Step 03
Weighted scoring.
Sub-scores are computed per category and rolled into a composite under ARCO Standard 2026.1, Sections 3.1–3.6.
Step 04
Committee finding.
A composite at or above 8.5 with no automatic disqualifiers qualifies the contractor for accreditation.
