We are a LA based company employing local staff and contractors, with both company directors living in LA with their respective families. Our mantra is "Quality not Quantity" which is strongly driven and measured by upmost client satisfaction. As a reasonably new entrant to the competitive LA building industry, we have focused on developing strong relationships with our clients and industry consultants upon which our business success relies. We have a combined 20 years' experience in the roofing industry with a proud history in being able to provide construction services to the wider LA region, focusing on the majority of the LA county.

"I got 3 estimates for my roof and gutter replacement. Rafael And Iris Roofing by far gave the most thorough written proposal as soon as they were done -- having spent more than 90 minutes on my roof (everyone else sent theirs a day or two later and only one came close to the level of detail of Rafael And Iris Roofing). Aviv spent another 30 minutes walking me through their proposal, showing me pictures they had taken, explaining recommendations and answering my questions. The resulting work was high quality, on time, in budget and nothing was too much trouble for Aviv, Lisa and Carlos throughout. Excellent customer service, good price, fast work, great cleanup."

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."

Roof sealant applications FAQs

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.
