Bay Contractor Group | Roofing Services in Oakland, CA 94601

Reroofing with Bay Contractor Group involves a complete tear-off of the old roof, which allows us to inspect and replace any deteriorated underlayment—the critical waterproof barrier beneath your shingles. This is a common issue in Oakland due to age and moisture. By installing new, high-quality underlayment and proper ventilation during the reroofing process, we restore your home's primary defense against leaks and moisture damage, ensuring a solid foundation for decades.

Flashing failure is a leading cause of leaks in Oakland homes, especially around chimneys, vents, and skylights where water can seep in. Our repair process involves carefully removing the failed flashing, inspecting the surrounding deck and underlayment for water damage, and installing new, code-compliant flashing sealed with professional-grade materials. For skylight installation or repair, we pay extra attention to integrating the flashing with the existing roof system to prevent the very leaks that plague many local properties.

Absolutely. Properly installed and maintained gutters are your roof's first line of defense. In Oakland, clogged or failing gutters cause water to back up under the roof edge, directly saturating and deteriorating the underlayment and roof deck. Our gutter installation, cleaning, and repair services ensure water is channeled safely away from your roof and foundation. This proactive protection is key to extending the life of your roof's underlayment and preventing the interior water damage that often starts at the eaves.
