New City Roofing Co | Roofing Services in San Francisco, CA 94116

Shingle curling in San Francisco is often caused by our intense sun exposure and thermal cycling, which can dry out and warp asphalt shingles. Our team assesses the extent of the damage and provides targeted repairs or a full replacement using high-quality, UV-resistant shingles better suited to our local climate, restoring your roof's protection and curb appeal.

Persistent fog, salt air, and moisture in the Bay Area accelerate corrosion on metal flashings around chimneys, vents, and valleys. We inspect all flashing points, remove corroded sections, and install new, corrosion-resistant flashing (often using metals like galvanized steel or aluminum) sealed properly to prevent leaks and protect your home's interior from water damage.

We recommend bi-annual visual inspections, especially after heavy wind or rain. Look for early signs of shingle granule loss, lifting edges, or discolored/rusted flashing. Keeping gutters clear and ensuring proper attic ventilation also helps mitigate heat and moisture buildup. For a professional assessment tailored to your home, our team offers complimentary inspections to catch small problems before they become major repairs.
