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 describe Stonebrook Exteriors as professional, responsive, and easy to communicate with, with high-quality roofing and siding workmanship. Customers also highlight help navigating insurance claims, thorough project management, reliable cleanup, and a willingness to address issues.
We had a great experience with Stonebrook Exterior. Kyle was extremely knowledgeable and came prepared with a detailed quote after assessing our property using Google imagery and a drone. Out of the three contractors we received quotes from, Kyle's was by far the most thorough. He arrived on time for our appointment, answered all of our questions, and provided helpful suggestions and expert insights throughout the process. Communication was excellent from start to finish. Kyle kept us informed when the permit process took longer than expected and worked around an unexpected rainstorm to ensure the project was completed before the weather became an issue. He stayed in contact with us every step of the way. After the county completed the final inspection with no issues, Eleanor was very helpful in finalizing the payment process. Overall, we had an excellent experience with Kyle and the entire team at Stonebrook Exterior. We would highly recommend them to anyone looking for a professional, reliable, and knowledgeable contractor.
Awesome installer, great to work with, communication and quality 10/10. Can’t wait to do business again.
A team of true professionals. All the project managers and estimators go above and beyond to make sure everything is accurate and communication is fantastic!
The team of Cole and Cody was fantastic. As with any projects, hiccups are unavoidable but the response from the company is outstanding.
Stonebrook is a very thorough and professional company. They did a fantastic job using some of our materials on a large greenhouse re-glaze in Colorado.
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.
