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!"

We are a full service roofing company. Our focus is in residential and commercial roofing, We work with many manufacturers for all types of roofing from metal to asphalt shingles to all types of low slope roofing membranes. Additional phone - (508) 299-7663.

"Called On top roofing for an estimate, it took several weeks to get back to us, got the estimate and agreed to have the work done. A few guy showed up one day and started working, we were not notified they were coming to work,good thing we were here that day. They did the job and left without ever communicating with us about the work. We did a walk around and discovered that some of the work was not completed. So called the company back and the owner came out to look at the job, he said it would be about another $100. To complete. We were not happy because this was supposed to be in the estimate we agreed on. The workers show up again unannounced and did the job. We then received a bill for $200. More, again this was not what was agreed upon when talking to owner. We were hoping to form a relationship with this company for future work, but that's not going to happen, there was no communication and even with a written contract they will somehow charge you more than agreed on."

FAQs for roof sealant application projects in Nashua, NH

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.
