"I had a FANTASTIC experience with LCT! It started with a prompt response from them, setting up an appointment the next day after a tree fell on my house. James came down and explained everything thoroughly and gave me some options. After talking to a few other vendors, I knew I wanted to go with LCT. Their pricing was better than the other quotes and James was great to work with. Before the crew started any work I met the owner, Luis, and knew I had chosen the right company. He was just as great as James, very thorough and let me know what would be happening. In addition to needing the roof replaced we also had some damage to rafters and decking to replace. After the job was complete, Luis did a thorough inspection of the work and made sure I was happy with everything. The crew did an amazing job and I couldn't be happier with the work. The office staff was also great to work with! I got to meet them when I went down to pay the invoice. A 5 star experience from start to finish. Thank you LCT!"

FAQs for roof sealant application projects in Gloucester, 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.
