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.

"I had Mr Simpson out to do an estimate he was able to come out the very same day. I was calling other companies and they wanted to make special appointments. I was busy and I had a leak in my roof and I didn't know what to do so I seen the reviews for Mr Simpson so I figured I'd give him a try when he came out to look at the job. He told me that I did not need a new roof that I just need it some preventative Maintenance and I should be fine and he also suggested coding the roof with a grey silicone coating to preserve the membrane and make it last longer he gave me a fair price and he also said that he could do it the next day. I usually don't hire people on the spot. I usually get more than one Estimate but the young man seemed very knowledgeable and showed me pictures of my roof and showed me what was going on and explain to me the membrane that I haveit's supposed to be maintained and I never did have any type of maintenance done so I agreed and he did the job "

"Never never buy from these thieves! We bought 8 windows to be replaced on the 12th of March 2025. The 17th of May they came to install. They didn't replace our windows. They inserted smaller windows into the old window frames(less light in the house). So now we have old cracked visible window frames. Silicone seals were not replaced. And the double hung windows can only open a third of the height, not half way up."
