"Demetri did a great job on Re- finishing my 100 year old pine floor and sealing it. He also replaced 35 year old+ trim around my storm door and painted the door. It is beautiful now. He repaired my chimney which was crumbling at the very top and put a cap on it and I found him to be extremely knowledgeable. He repaired my garage shingles as needed and fixed its gutter spout drain pipe and another drain pipe on the house. He also did power washing and installed a saddle between my living room and dining room and fixed my bannister. "

"Came to house immediately to assess the job (remove and replace 3 blocks of walkway concrete with metal mesh, including cleanup and removal of debris). I was told the work would be done the next day, but there were weather issues, and was promised they would do it the day after ... which they did. They showed up promply and got right to work. They clearly had the expertise to do the job, and focused on doing it correctly. The work took most of the day, and they stayed with it to make sure it was completed and correct. Due to unique contour, the ground to the sides needs to be tapered, which is fine as I can do that easily to my liking ... So, I am satisfied with the work."

"I hired Supreme Island to replace the roof of my home, and I only have good words to tell about these guys. They are the most professional home service company I have ever used. Unlike the other contractors that were all pushy, they told me that the roof needed replacement and it would not be in my best interest to waste money in repairs. Having heard so, I gathered estimates from all the other contractors. Supreme Island?s estimate was by far the best. I felt very comfortable making the decision on going with them because they did not push me at all. They explained to me in detail everything that was going to happen. I was updated for every single process of the roof. They all the pictures of every step of the roof so I can keep them forever. I am extremely happy with them. Look no further, this is the company to hire!"

FAQs for roof sealant application projects in Central Islip, NY

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.
