Acme Roofing | Roofing Services in Gilroy, CA 95020

Gilroy's climate, with cool nights and warmer days, can create condensation in poorly ventilated attics, leading to moisture in roof insulation. This reduces efficiency and can cause mold or rot. We fix it by first diagnosing the source—often inadequate ventilation—and then installing proper intake and exhaust systems, along with vapor barriers, to keep your attic dry and your insulation effective.

Signs include interior water stains, a musty smell in the attic, or granules from your shingles collecting in gutters. For Gilroy homes, worn underlayment is a major vulnerability. Our process involves a careful tear-off of old materials, inspecting the roof deck for damage, and installing new, high-quality synthetic underlayment that provides superior protection against moisture and wind-driven rain common in our area.

It depends on the extent of the damage and the age of your existing roof. For localized issues, we can often perform a targeted repair by removing the affected shingles, replacing the compromised underlayment section, and reinstalling new shingles to match. However, if the underlayment is failing in multiple areas or is near the end of its lifespan, a full replacement is more cost-effective and reliable for long-term protection of your Gilroy home.
