Gatana Roofing is the commercial roofing division of Gatana Construction, a Bay Area general contracting firm with nearly two decades of experience in commercial construction, exterior waterproofing, and property repair.
Founded by Georgio Atana — a licensed general contractor with 19+ years in the field and 12 professional certifications — Gatana brings a deep understanding of how roofing systems interact with the full building envelope. We don't just replace membranes; we solve building performance problems.
Our focus is commercial and multi-unit residential properties. We work with property managers, building owners, REITs, and general contractors across San Francisco, the Peninsula, the East Bay, and the greater Bay Area region.
At Gatana, we view commercial roofing as a critical system within a larger building envelope — not an isolated trade. This perspective, gained from years of doing full-building construction and waterproofing, allows us to identify root causes that purely specialty roofers might miss.
Whether you're dealing with a persistent leak, planning a full replacement, or need a comprehensive inspection for a property acquisition, we bring the same thoroughness and technical rigor to every engagement.
As part of Gatana Construction, our roofing clients also have access to complementary services — including exterior waterproofing, siding, stucco, window and door replacement, and structural repairs — making us a single point of coordination for complex building repair projects.
We serve property management firms, commercial building owners, HOA boards, and general contractors throughout the Bay Area.
