Alpha One Roofing | Roofing Services in San Leandro, CA 94577

We perform a detailed roof inspection to assess the flashing's condition. If lifting is found, we carefully remove the compromised flashing, prepare the area, and install new, high-quality flashing sealed with professional-grade materials. This precise repair prevents water intrusion at vulnerable joints, which is crucial for protecting your home from leaks, especially given our local weather patterns.

For homes experiencing underlayment deterioration, we recommend a full roof replacement to ensure complete protection. We strip the old roof down to the decking, replace any compromised wood, and install a new, robust synthetic underlayment designed for longevity. Combined with quality shingles and proper ventilation, this addresses the root cause and provides a durable, weather-resistant roof suited for the Bay Area climate.

Absolutely. While repairing the primary issue (flashing or underlayment) is essential, our moisture control inspections and installations provide a critical secondary defense. We assess attic ventilation, install vapor barriers if needed, and ensure proper drainage away from the roof's edge. This comprehensive approach manages interior humidity and prevents condensation, which protects your home's structure and complements the roofing repairs.
