Mighty Dog Roofing of North Boston is run by Amar Nyamdavaa, and across years of reviews he's the one people name directly — the guy who shows up, explains the problem, and sticks with a job until it's actually fixed. The pattern that stands out most isn't the easy jobs; it's the hard ones: a raccoon that had chewed through a rubber membrane, three-plus layers of old tar and gravel on a row house roof, a 170-year-old brownstone needing a flat rubber roof, mansard shingles and a skylight all replaced at once, and a flat-roof ADU with rotted plates and uneven surfaces underneath multiple layers of old material. The company holds a near-identical 4.9-star average across three platforms — Google (64 ratings), Angi (10), and HomeAdvisor (13) — and the Better Business Bureau grades it A and lists it accredited, with Massachusetts contractor license numbers (207065 and CSSL-106223) on file through its listing. One recurring thread in the reviews is Amar declining to oversell: a 2026 reviewer described getting a second opinion after another roofer called for a full replacement over a raccoon-damaged membrane, and Amar fixed the actual problem instead. Reviewers also point to siding and gutter work beyond roofing itself — a full garage re-siding, new siding on a whole house, gutter cleaning and repair — as places the same crew and communication style carried over. Not everything on file is glowing. A reviewer in April 2026 described signing a contract in mid-February for a roof repair, having payment collected quickly, and then not getting the promised two-day scheduling — having to follow up multiple times before work moved forward. It's the one sour note in an otherwise consistent run of recent reviews, and worth asking about directly: get a firm start date in writing rather than a verbal promise. Mighty Dog is a solid call for roofing work that isn't straightforward — an old or unusual roof, a leak nobody else could find, a full re-roof alongside siding or gutters — and Amar's own follow-through gets cited again and again. Just pin down the schedule before signing.
Amar came out to give a free consultation. Ultimately the job wasn't a fit for them but Amar was patient, passionate, and offered some good advice.
Amar at Mighty Dog is a true professional. He is responsive, diligent, and does a great job. I’ve had several issues on my roof over the last few years. His team and him were able to timely resolve each of them. I would trust them for any future projects.
I’d give Amar 10 stars if I could. I hope this helps anyone researching roofing contractors. After another contractor left us without any chimney flashing, a neighbor recommended Amar. Since we’d already been burned once, I got quotes from five different companies, including Mighty Dog Roofing. Amar came out within 24 hours of my call and sent an estimate later that same evening. He was one of only two contractors who actually got up on the roof to inspect the damaged areas instead of relying solely on drones or a sales technician. He didn’t try to pressure us into buying a new roof and was upfront about when he believed a full replacement would actually be necessary. We were originally scheduled for repairs early the following week, but Amar called on Friday to say his team could come sooner because rain was expected over the weekend. They worked efficiently, and Amar personally oversaw the job. This entire fiasco could have been avoided if I had known to call Amar’s team from the beginning.
I would strongly caution anyone considering Mighty Dog Roofing. I signed a contract in mid-February for a roof repair. They were quick to secure the agreement and payment, promising scheduling within two days. That timeline was not honored, as I had to follow up myself after multiple days after putting down a deposit. When work was performed, it was not completed as outlined in the contract. Despite paying in full, the remaining work was never finished. I was told when I first mentioned the incomplete work “atleast you have a warranty if it still leaks” - although they breeched the contract. Over the next several weeks (nearly a month 1/2), I experienced repeated missed appointments, unreturned follow-ups, and little to no communication unless I initiated it. I spoke with Kazi (sales manager) multiple times as well as Kyle. At one point, it was suggested the incomplete work might be addressed later alongside a separate siding project, which I declined after not fully completing the first job. After many ongoing delays, I requested a partial refund for the incomplete work. I was told, after discussion with the owners (Vish), that refunds are only issued in cases involving property damage. Only after I requested a refund did there seem to be any “urgency” to return and complete the job. Although, it has now been a week and I didn’t respond as I’d rather spread reviews so no one else has this experience. During the sales process, the company shares a story about how the owners started the business after having a negative experience with another contractor and wanting to do better for customers. Based on my experience, that message was not reflected in how my project was handled. Based on my experience, the contracted scope was not fulfilled within a reasonable timeframe, and communication and follow-through were inconsistent. Once they receive their $$$, you no longer are of importance or urgency to them. I recommend proceeding with extreme caution and ensuring all work is completed to satisfaction before making final payment.
