A persistent valley leak often requires a comprehensive approach. At Amex Roofing, we start with a detailed inspection to pinpoint the exact failure point—often worn flashing, compromised underlayment, or debris buildup. Our repair focuses on sealing the valley with high-quality, waterproof materials and ensuring proper drainage away from the roof. Given San Jose's weather patterns, we also recommend preventative measures to protect this critical area from future issues.

Skylight leaks in San Jose are frequently caused by failed perimeter flashing or sealant that has degraded due to sun exposure and thermal expansion. A permanent fix isn't just about re-caulking. Our experts remove the old flashing, install new, corrosion-resistant flashing that's integrated with your roofing material, and apply specialized sealants designed for our local climate. This ensures a watertight seal that can withstand seasonal temperature shifts and heavy rains.

Proactive maintenance is key. We recommend bi-annual roof inspections, especially before and after the rainy season. We'll clear debris from valleys and gutters, check for cracked or missing sealant around skylights and vents, and ensure all flashing is secure. For older roofs, a preventative coating or targeted reinforcement in high-wear areas like valleys can significantly extend your roof's life and prevent leaks before they start, saving you from costly interior water damage.
