Commercial Roof Replacement
Done Right Since 1952
When repair is no longer the right answer — when seams have failed across the whole roof, when patches outnumber original membrane, when the deck itself shows damage, or when a commercial roof has simply reached the end of its service life — replacement becomes the responsible call. Keith Roofing has been doing commercial replacements across San Jose, Santa Clara County, and the South Bay since 1952, and several Bay Area property management firms have us on their preferred-contractor lists for exactly this kind of work. We handle apartment complexes, office buildings, churches, multi-tenant retail, industrial facilities, and HOA-managed common-area buildings. Our commercial work concentrates in the area's main office and industrial corridors — Sunnyvale's Mathilda and north-Sunnyvale industrial belt, Cupertino's Stevens Creek office parks, and Santa Clara's Mission College and Great America commercial districts are all places we work regularly.
Commercial replacement is fundamentally a coordination project as much as it is a roofing project. Tenant operations need to keep running. Building access needs to stay clear. Adjacent systems — solar panels, HVAC equipment, communication antennas, drainage, parapet walls — all need to be carefully detached, protected, and reinstalled. Sequencing matters: each phase of the tear-off needs to be weathered-in by end of day so a sudden storm doesn't damage the interior. Documentation needs to match the operational reality of commercial property management — written scope, line-item billing, photo reports, manufacturer warranty paperwork, and a closeout package that fits into reserves records or insurance files.
Our commercial replacement work covers the full range: single-ply replacements (single-ply) for low-slope and flat-roof buildings; multi-ply replacements (modified bitumen and BUR) for buildings where heavy traffic, ponding water, or insurance specifications require it; combination roof systems where a single building has pitched sections (composition shingle or tile) tying into flat sections (single-ply or mod-bit); and solar coordination for buildings with rooftop PV — we work with your existing solar installer or coordinate detach-and-reset through a partner.
