For a condominium or townhome association, a roof replacement is usually one of the largest projects the reserve fund pays for. It also comes with predictable friction: residents worried about assessments, a board that needs comparable bids, and a community manager coordinating access for dozens of units. This guide walks San Jose and Santa Clara County boards and managers through the process. The goal is a decision you can defend at the next board meeting.
1. Start with the reserve study, not the leak
California law ties roof planning to the reserve study. Under Civil Code §5550, the board must have a reasonably competent and diligent visual inspection of major components, roofs included, at least once every three years, and must review the reserve study annually (Civ. Code §5550; summary at Davis-Stirling).
Use the reserve study's remaining-useful-life estimate as a starting point, then confirm it with an on-roof inspection that includes photos. A roof can outlast its estimate, or fail early because of drainage, flashing or installation problems.
Rainy-season tip: San Jose gets most of its rain from November through March. The National Weather Service reports 82% of yearly rainfall in those months (NWS, Climate of San Jose). Use winter for inspections, documentation and bidding, and plan full tear-offs for drier months whenever you can.
2. Repair, restore, or replace?
Ask for all three options in writing:
- Targeted repairs: fix specific failures and buy time if the roof is otherwise sound.
- Restoration or coating (for suitable low-slope sections): may extend service life. Ask for the manufacturer's requirements and warranty terms in writing.
- Full replacement: when the roof deck, insulation or membrane is past the point of reliable repair.
Many San Jose HOAs have mixed roofs: steep-slope sections over units plus low-slope areas over garages, breezeways or podiums. Make sure each bid covers every roof type and lists them separately.
3. Bidding the project
Give every bidder the same roof-by-roof scope so the board compares like with like. Our guide to comparing commercial roofing bids covers what to line up side by side.
4. Permits and energy code
Re-roofs generally require a building permit. For low-slope roofs, California's Title 24 energy code may require a cool roof product when a large enough share of the roof is replaced, recovered or recoated. The thresholds and exceptions are explained in the BayREN 2025 Nonresidential Roofing Permit Guide and by the California Energy Commission. Residential and nonresidential rules differ, so ask your roofer which rules apply to your buildings, and confirm with the City of San José's building division.
5. Coordinate with other required inspections
If your association has elevated balconies, decks or walkways, SB 326 requires periodic inspection of those elements and their associated waterproofing (Davis-Stirling on SB 326). Roof work often touches the same building envelope details. Coordinating schedules and scopes can reduce repeat access and conflicting findings.
6. Communicate with residents
- Share a project calendar by building, with expected noise days and parking or access changes.
- Explain how funding works (reserves vs. special assessment) in plain language, with the board's counsel or manager approving the wording.
- Give one point of contact for questions and interior-leak reports during the project.
