"Alluring Homes recently replaced my roof, and I couldn’t be happier with the experience. It was in desperate need of repair, and the idea of tackling such a big project felt overwhelming. But from the very beginning, Cesar made the entire process feel manageable. He took the time to explain each step, patiently answered all my questions, and helped find smart solutions for some unique challenges that came with my particular situation. I also had the opportunity to work with Sergio, the owner of the company, who came out personally to make sure everything was running smoothly. That kind of hands-on care really stood out. After meeting with several different contractors, it was clear that Alluring Homes was the most knowledgeable and reassuring. The work was done at a fair price, and the final result looks amazing. I feel confident knowing the job was done right. If you're looking for a trustworthy, skilled team to handle your roofing project, I would highly recommend Alluring Homes."

At FRONTLINE ROOFING INC, we're all about delivering top-notch quality in everything we do. Our values are simple yet powerful: fairness, honesty, and taking personal responsibility. What truly makes us stand out is our dedication to not just meeting, but exceeding customer expectations.But above all, it's our genuine care for our customers that drives us: we listen, we understand, and we make sure their needs are at the heart of everything we do.

"They came out, inspected the roof and provided a quote. I signed off on the contract and was told that it would be 7-10 days for the materials to come in and that we would get a call to set up the repair appointment. Two weeks later we'd heard nothing and when I called I was informed that they actually could not do the repair. This had been determined within two days of my signature on the contract and I NEVER received any kind of notification. So now, the roof is still leaking and I'm back to square one. While they were pleasant to deal with, the lack of communication is completely unacceptable."

FAQs for roof sealant application projects in Altadena, 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.
