"I initially hired Airtight Construction to replace my roof around August of 2020. Once airtight construction started working on the roof they informed me it was going to cost more. I was never given an estimate or a contract for the additional work. To date still no bill, though they ask for money continuously. While we are waiting for a roof inspection they started a kitchen remodel around sept. 2020. They removed my kitchen cabinets, replaced a few windows and did some electrical work. I began to worry about the work being done and called the city of Martinez for an inspection. They said some of the work Airtight Construction had done needed to be fixed. Things like Electrical Panel, the windows all needed to be removed because there was no sheeting. There are structural questions about how some of the beams they installed are going to be supported.. I now know no permits were pulled for the kitchen remodel,. though I asked for permits several times. I am now having to spend more money to hire new contractors to complete the job."

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.
