John J Griffin Roofing - San Diego's Professional Roofing Repair

In San Diego, shingle curling is often caused by prolonged UV exposure and thermal cycling, which breaks down the adhesive strips. Coastal humidity can also contribute. John J Griffin Roofing fixes this by first assessing the underlying deck for moisture damage. We then replace affected shingles with high-quality, UV-resistant architectural shingles designed for our climate, ensuring proper sealing and ventilation to prevent recurrence.

Salt air from the Pacific Ocean accelerates corrosion on standard metal flashing, leading to leaks around chimneys, vents, and roof valleys. Our solution is to install corrosion-resistant materials like aluminum or copper flashing. During a repair or replacement, we meticulously seal all flashings and integrate them with new underlayment, creating a watertight barrier that stands up to San Diego's coastal environment.

Not necessarily. Many localized issues like flashing corrosion or a few curled shingles can be effectively spot-repaired if caught early. We'll conduct a thorough inspection to assess the overall roof health. If the damage is isolated and the surrounding materials are sound, a targeted repair is a cost-effective solution. We always provide a clear, honest recommendation based on the long-term protection of your San Diego home.
