ARCO Review Findings
Delgado’s Roofing is highly regarded for its transparent pricing, professional communication, and high-quality workmanship. Customers consistently praise Mario and his crew for their efficiency, punctuality, and commitment to keeping the worksite clean.
I called Delgado Roofing about a roof leak I found. Mario and crew came the next day, found the problem, showed me pictures of the area that needed fixing and gave me a fair price for the work and materials. Mario was very proactive in keeping me informed of the progress and they finished that same day. We were very pleased with the job well done and will highly recommend Delgado Roofing to anyone who needs roofing work done.
Delgado Roofing did a great job on my large roof. Mario was transparent on pricing and materials to be used. Mario completed all work on schedule. The overall quality of the completed roof project is outstanding. I received three bids for this project, and Mario had the best price without sacrificing quality. I highly recommend Delgado’s Roofing.
After collecting a few estimates we decided to go with Delgado. We are very happy we did. The final results look great! Mario was great to work with and always quick to answer quesrions we had. During the project we found the previous roofers had not used any sheathing. After discussing with Mario we decided to add plywood sheathing to help keep our home water tight. Mario's crew worked from sun up to sundown to make sure our project was done on time. The additional cost of the sheathing was reasonable and easier to swallow when Mario had advised us about that possibility ahead of time when we got the estimate. We would definitely recommend Delgado roofing going forward!
As a Realtor, I keep a running list of recommended contractors so when a client asks for a referral I'm confident they'll be in good hands. Delgado's Roofing has been my go-to roofer for several years, and I recently had them replace a roof on a property of my own. They were efficient, timely, & did a great job with clean up and communication. Will continue to highly recommend.
Mario and his crew did an excellent job! Attention to detail, and at a fair price. I highly recommend them for any roofing needs! 10/10!
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.
