- Workmanship guarantee — a stated 10-year guarantee offered on reshingling jobs

Twenty-nine Google ratings average 4.9 stars for Dempsey Brothers Roofing, a Duxbury outfit that describes itself as family-owned and run by brothers, with — in its own words — 'generations of expertise' behind it, though it doesn't post a founding year. It works the South Shore: full roof replacements, repairs, reshingling, storm and insurance-claim work, and gutters. This spring's reviews describe an entire roof replaced at a price a bit under competing quotes, finished on time and left clean, and a garage reshingled with a stated 10-year guarantee on the work. Another crew finished a flat roof within a few days, and one technician tracked down the roof's existing specifications before the job started and walked the homeowner through photos of what he found. None of the last seven months' reviews turned in a single negative rating, and across all 28 written reviews since last September, the same qualities keep showing up: on time, communicative, and clean about cleanup. One thing worth flagging: a five-star review posted this spring on the same Google listing is credited to 'Rova Roofing,' not Dempsey Brothers — a sign this listing may share space with, or have inherited reviews from, another business. It says nothing about the quality of Dempsey Brothers' own work, but it means the review count is worth reading with a little caution. The review history itself is also young — it only stretches back to last September, so there isn't yet a multi-year run to point to. For a standard reroof, a reshingling job, or gutter repair on the South Shore, the reviews that clearly describe this business point to a crew that shows up, communicates, and cleans up after itself. Confirm current licensing and insurance directly before booking — neither is documented here.

Paula Nelson and David Nelson. Rova roofing has done a great job on our new patio and roof. It is so much more comfortable now. They arrived on the 21st and completed our roof in just one-day. We were impressed with the workers' professionalism and cleanliness. Rova Roofing has done a great job on our roof. We recommend them for any kind of roofing work. Crew chief Collin is always prompt to respond to calls and emails. Paula Nelson & Dave Nelson rate them 10/10.

Local company who did a fantastic job. We had our entire roof replaced and their price was just a bit less than other quotes. All was finished on time and was as clean before they began. I highly recommend.

Jim provided me with an estimate for the reshingling of my garage's roof in 2017. The roof of my garage was in bad shape at the time. Jim was very professional, prompt and knowledgeable. He answered every question I asked and completed all the work on time. I'm writing a review, as for me the most significant part of a roof job is not just the initial work done, but also how the work will hold up over time. How long will a roof last after it is installed? Jim stated that he offers a 10-year guarantee on his work, but the material can last longer depending on how it is installed. The roof has lasted three Wisconsin winters and two Wisconsin summers. I have not had any problems. Jim also added an additional vent to the roof's top (the previous roof did not). After three-years, I am able to say that the feature has helped keep the garage cool in the summer. I recommend Energies Savers without hesitation to anyone seeking a company who cares deeply about their clients and is committed to quality. -Craig G

We were satisfied with the roof repair business because they repaired the damage to the roof quickly and efficiently. They provided a guarantee for both the materials and the work.

Nathan was above and beyond. He had the ability to locate the specifications on my roof prior to the job, and was very prepared. He took pictures of my roof and showed me the images. It was neat to learn a little about my house's past through images on its roof. Highly recommend!
