My previous roof failed within 5 years of install. Claiming the warranty turned out to be a futile finger-pointing exercise between the contractor and manufacturer. I was extremely stressed and lost sleep due to this mess. Every single contractor suggested a new roof but Firon was able to diagnose the leakage and assured me that the roof could stay for a few years more. They even came in promptly whenever I had other roof issues (not due to Firon work). Now it’s time to re-roof and I know who I can trust.
