From the start, communication was great — calls and texts were returned quickly, and they showed up when they said they would (which, let’s be honest, is half the battle).

"I don’t normally write reviews, but I had such a great experience with Roofing Angels that I had to share. Chuck was amazing—from the first meeting, he made sure I understood everything about the process and helped me choose the right materials for my home. No pushy sales tactics, just honest advice. His crew was super professional and hardworking. They showed up early, worked long hours, and always made sure to clean up at the end of the day. I was expecting a lot of noise and disruption, but honestly, it wasn’t bad at all. Now that the job is done, I can’t stop admiring my new roof!

FAQs for roof sealant application projects in Duarte, CA

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.
