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
Reviews consistently describe Justin and his crew as professional, knowledgeable, responsive, and communicative, with fair pricing and high-quality workmanship. Customers also highlight quick project completion, thorough service, and leaving work areas clean.
Justin and his team at Powerhouse Exteriors put a new roof on our house and it’s beautiful!! We couldn’t be happier. They were professional, the cost was very competitive, they were true to their word and finished this project in a days time. The cleanup was excellent too. We will definitely be calling him for future projects!
Big windstorm last May damaged a lot of trees and roof shingles in our area. Justin knocked on my door a few weeks later and informed me of the damages in my roof. Gave me a competitive price quote and got the repairs done in time for the strong rains. Justin was a pleasure to work with. He was honest unlike another roofing company who tried to dishonestly sell me significantly more than I needed. I appreciate the professionalism and the extra effort to expedite the work to avoid any further problems.
Highly recommend working with Justin. He is thorough in his assessment and does high quality work. We’ve had him out for two projects and both were completed quickly and at the quoted price. When a project is not in his normal wheelhouse, he connects us with the right people. We look forward to working with him in the future.
Justin and his team was a pleasure to work with an did an amazing repair job. I had a leak near my chimney that was causing black mold in my garage. They replaced everything needed and it looks great! Thank you Powerhouse Exterious. Would definitely go through you guys again.
Outstanding job! I will definitely reach out to this company again when the time comes.
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.
