Tar Star Roofing is Anthony Mitchell's Haverhill roofing business, and customers describe calling him when a roof starts leaking. The company lists slate, shingle and flat roofing plus chimney repair, and names a service area of Andover, Boston, Haverhill, Lowell and Newburyport. HomeAdvisor shows 4.9 stars from 73 ratings, Google 4.5 from 16, and its BBB grade is A+. Customers describe fast visits for leaks. In June 2026, a customer said Anthony quoted a leaking skylight from photos and came the next day, and an Angi reviewer said he came the day after a call about a bad slate-roof leak and gave a price they could live with. A May 2026 reviewer said Tony kept in close contact through constant weather delays. In a September 2025 review, a customer said Anthony inspected a leaking porch roof the same day, fit the job in two days later ahead of more rain, finished in one day, and secured a loose deck railing without charging. In 2025, two customers described pressure to pay cash. In June 2025 an Angi reviewer said the company demanded cash on the spot and gave no invoice. In a March 2025 review, a customer said a worker started on their roof before any work was authorized, the quote then dropped by more than half if they paid cash, and when they refused, the owner hung up on them. The state registry shows Massachusetts home improvement contractor registration #205180, held by Anthony Mitchell, as active.
I had a bad leak in my slate roof. The Tar Star owner Anthony called and came the next day. Saw what was needed, understood my money concerns gave me a price I could live with and started work at 7;30 the next day which was a Saturday. I could not be happier with.the quality of work and would recommend Tar Star Roofing any time.
We had a leaking skylight. Anthony returned my call right away, gave me a quote based on photos, and came over the next day to do repairs. He is clearly knowledgeable and responsive. Great work.
We highly recommend Anthony and Tar Star Roofing. Our roof project was challenging due to constant weather delays, but Tony stayed in close communication every step of the way, calling regularly with updates and showed up ready to work when the weather allowed. Anthony handled a difficult roofing job with professionalism, honesty. He made all the right adjustments along the way and even helped us with another little project we were working on. Tony clearly takes pride in doing the job correctly. It's hard to find contractors who are this reliable and genuinely care about their customers. We are extremely happy with the finished work and would absolutely recommend Tony to anyone looking for a trustworthy, hardworking roofer. Thank you, Tony!
Our roof was over 20 years old. It not only needed some repairs, but needed to be redone for the long haul. Anthony was responsive, seemed to correctly diagnose the problems we had on the roof, and proposed solutions that matched our budget and desired duration of a fix. He was very competitively priced compared to other bids. His worker was clean and courteous. They fixed the holes, put on a silicone sealant, and sealed gaps near some exhaust vents.

Typical Greater Boston range for this kind of work, from regional averages — not a quote from Tar Star Roofing. Use it to sanity-check bids, then get the real number in writing.
A square is 100 sq ft of roof surface — bigger than the floor plan because of pitch and overhangs.
