How long does a roof coating system last?

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.

How often should you recoat or reseal your roof?

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.

Can roof coating prevent roof leaks?

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.

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."

"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."
