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.
