ARCO Review Findings
Milwaukee Roofing consistently delivers high-quality workmanship and professional service, with customers frequently praising Jim and Kennedy for their clear communication, helpful guidance, and dedication to standing behind their work. Clients also highlight the team's efficiency, noting their ability to complete projects quickly while maintaining a clean and respectful job site.
We had Milwaukee Roofing do our gutters in 2020 and had a great experience so when we wanted to do our siding, soffits, and fascia this year they were our first call. Another excellent experience!! Even though it was mid October when we contacted them, they were able to complete the entire job in just under a month. Our house looks amazing and they helped with decision making along the way. Highly recommend!!
SUPER HAPPY with our new roof! From the extremely detailed inspection, to the explanations of our options and choices, to the immediate estimates that compared and contrasted, and to the actual installation itself over a weekend that included unexpected rain, we are 100% satisfied. The crew are stellar, working until the very last moment of daylight, and our house stayed completely leak-free even during the unwanted downpour. Jim and Kennedy answered all of our questions and provided guidance, and Jim himself attended to re-situating our gutter guards (installed by this company a couple years ago!) to make sure they fit well now that we had a brand new roof alongside them. THANK YOU ALL SO MUCH!!
Milwaukee Roofing did our roof three years ago (they were called Energy Masters at the time) and it’s holding up well, as are the gutters, flashing, and ventilation work they did. Jim is helpful even after a sale. He came out today to inspect the caulking on our flashing and his expertise won the respect of our chimney specialist. When Jim’s guys did the work three years ago, the huge team (that got the roof done in one day 💪) was skilled and professional.
We had Milwaukee Roofing out to replace our garage roof and our patio door a couple of years ago. Not only was their work exceptional, but they took the time to sit down with us and walk through the project from start to finish. They made sure that all available options were on the table and answered any questions we had. I am so confident in their work that we plan to have our home roof replaced with them in the coming month or so and have recommended them to all my friends and family in the area.
Milwaukee Roofing did a great job replacing our roof. Jim's communication was excellent. The team was professional, reliable and friendly. They were respectful of our property and took good care to prevent damage to our gardens. They also spent extra time to problem solve the source of a leak. We'd use them again.
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.
