Tar Star Roofing is the premier Roofing company serving New Hampshire and Massachusetts for over a decade. Our #1 goal as a company is having complete customer satisfaction and there is no job that is too big or too small. If you want your job done right, call Anthony today !

"During a recent heavy rainstorm, our porch roof started leaking enthusiastically. I found Anthony Mitchell (Tar Star Roofing) through Angi and I’m so glad I did. He was able to come by that very day and inspect the roof. He was very upfront about cost which I appreciated. We were expected another round of rain at the beginning of the following week, so he rearranged things to be able to fit me in just 2 days later. He completed the work within one day. Throughout the process he gave me updates on what he was doing, and explained everything clearly. While inspecting the property Anthony noticed that the railing on our side deck was coming loose, causing a hazard to the cars parked under it. He very kindly secured it for us, and didn’t even charge us. I will definitely hire him for future projects!"

"I hired Long Roofing Products to replace my roof. From the beginning the sales man lied to me, telling me that they could take off my Gutter Helmets and put them back on correctly. This was lie #1. They have null and voided the warranty of my gutter helmets, because they were not supposed to touch them and according to Gutter Helmets all the roofers know this. lie #2 there were missing pieces on the ends of my gutter helmets to prevent the birds from getting into the gutters. The salesman told me they would order the piece from Gutter Helmets and replace it. This was never done. I have contacted them several times and they continue to tell me they will fix it and they never do. I would NEVER recommend them, I would only tell you NOT to use them. They talk a big game but never follow thru with their promise's."

"NMTI (who we hired as Tru Blue Construction Inc) were superlative. Juan and Ramon were excellent communicators, answering all of our questions in a timely, professional, and endlessly patient fashion. Our project was a big one - our self-managed condo building had a severely leaky roof that needed a full replacement, including redoing a roof deck - and I imagine we were not the easiest clients since we had tons of questions and a lot of "cooks in the kitchen" with different owners and condo trustees weighing in. Juan and Ramon took it all in stride and were incredibly helpful for me in my role as project coordinator. Their team was clean, efficient, effective, respectful, and friendly. They worked both quickly and thoroughly, and were good to always keep me updated as the scope of the work evolved as we found new (but not unexpected or spurious) issues during the demo/rebuild process. Juan was an excellent advocate for us and our project when the city was slow to approve permits/send inspectors. It was a big and intimidating job for us as homeowners, and NMTI/Tru Blue made it feel much less overwhelming. We're thrilled with our new roof and deck and so pleased with the experience of working with Juan, Ramon, et al."

"Very disappointed. We asked for triple pane windows, and someone on their end ordered double pane. Luckily we noticed day of installation, and they had to re-order the proper ones we signed for. Finally the group of installers who came did a horrible job. Trash, insulation, and broken glass on our front lawn. Horribly cut wood trim that we had to redo ourselves. Poor sealing that we need to redo. Our hopper window was misaligned and couldn't close. The hinge arm on our casement window has detached from the channel. Communication is spotty from them, and sometimes we don't get an answer by call or text until we message repeatedly. It took over a year to have our project done from contract signing to end, and there are still issues cropping up. Out of the dozen of contractors we've hired the past year and a half, they have been the most disappointing and for what we paid, the quality of work was truly disappointing."

FAQs for roof sealant application projects in Charlestown, MA

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
