Common signs in our climate include interior water stains on ceilings or walls, especially after our rainy season, a musty odor in the attic indicating trapped moisture, or granules from asphalt shingles collecting in gutters. The underlayment is the critical water barrier beneath your roof's exterior, and SF's persistent fog can accelerate its wear. We recommend a professional inspection if you notice any of these issues to prevent structural damage.

The primary culprits in SF are strong coastal winds and thermal expansion from temperature shifts between foggy mornings and sunny afternoons. This constant movement can loosen the fasteners securing clay or concrete tiles. Our repair involves safely removing the affected tiles, replacing any damaged underlayment beneath, and re-securing the tiles with corrosion-resistant fasteners designed to withstand local conditions, ensuring a lasting fix.

We advise a professional inspection at least once a year, ideally in late spring after the winter rains. For older roofs or homes in particularly windy or fog-heavy neighborhoods like the Sunset or Richmond districts, a bi-annual check is prudent. This proactive approach allows us to catch and address minor issues like small underlayment breaches or loose tiles before they lead to significant leaks or interior damage.
