If your home or commercial building has a tile roof that’s been standing strong since the 1990s, it may be time to give it some extra attention. While tile roofs are often marketed to last 50 years or more, there’s one crucial component that doesn’t always last as long—the underlayment.
The Hidden Weakness in Your Tile Roof
Many homes and buildings constructed during the Orange County building boom of the 1990s were fitted with tile roofs. These roofs were designed for durability, but the underlayment beneath them—often a single layer of builders-grade asphaltic material—typically only lasts between 20 to 30 years. Without proper maintenance, factors like UV exposure, thermal shock (rapid temperature changes), and moisture can accelerate its deterioration.
Why You Shouldn’t Ignore Aging Underlayment
A failing underlayment means your roof is no longer providing the full protection your property needs. Cracks, leaks, and water damage can creep in, leading to costly repairs if left unchecked. The good news? You don’t have to wait for a problem to appear—an inspection can help you stay ahead of any issues and protect your investment.
