Many homeowners assume roof replacement must happen in peak summer. In the Bay Area, that’s often convenient—but it’s not the only workable window.
The “best” time is a mix of weather risk, crew availability, and your roof’s urgency.
Bay Area season planning in plain language
Dry season
More predictable scheduling and fewer weather delays. This is when demand is highest, so lead times may be longer.
Shoulder season
Often a great balance: decent weather windows plus easier scheduling. It’s also a smart time to address ventilation upgrades and detail work before storms.
Rainy season
Full replacements can still happen with planning, but crews may need to stage work in sections and protect exposed decking carefully. If you have active leaks, start with a repair or temporary containment plan.
What affects your schedule more than the month
- Material lead times: specialty shingles, skylights, or custom metal can add time.
- Permits and HOA approvals: some neighborhoods require documentation and timelines.
- Roof complexity: steep slopes, multiple valleys, and skylights take longer.
Smart planning timeline
- Inspection + scope confirmation
- Material selection (and ventilation/drainage plan)
- Permits (if needed)
- Install window selection based on weather forecast
If you can’t wait: what to do right now
If you have an active leak, you may need roof repair or temporary containment first. See our rainy season repair guide and emergency tarping guide.
