ARCO Review Findings
Mighty Dog Roofing is highly regarded for their professional, efficient, and high-quality workmanship, with many customers specifically praising their ability to handle complex insurance negotiations. The team is frequently commended for their clear communication, responsiveness, and thorough cleanup after completing roof replacements.
Removal of old wood roof and installation of new roof. Jorge and his crew did an excellent job. I’m very happy with the result.
I don't have enough good things to say about these guys! Any issues with a roof is the last thing anyone wants to deal with, let's be real. But they were SO on top of it, informed me every step of the way & did great work. Having the drone inspection done was a life saver and it was so easy. At first, I didn't want to deal with it but now, I won't go without it. Thank you Mighty Dog for exceptional service!! You guys rock! Forever a customer & advocate for this company!
Mighty Dog Roofing was a great experience from first contact all the way through completion. The team was professional, and they did an excellent job. I highly recommend them
I’ve worked with these guys before with clients and then personally used them and they did a phenomenal job. Greg came over addressed all the issues , met with insurance adjuster , and played a huge role in getting my roof approved and negotiated a great deal ! My roof looks amazing and I’ll keep on referring all my clients to you ! Thank you
We used Mighty Dog to replace our roof after the May 2024 hail storm. From start to finish, Mighty Dog was easy to work with - responsive, communicative, professional, and attentive. Mighty Dog did a great job dealing with our insurance company, showed up when they said they would, had a pleasant and efficient crew, and made the whole process as seamless as possible. We highly recommend Mighty Dog!
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.
