Gutters, leaves and storm drains: the easiest roof prep for an El Niño winter
Clogged gutters are one of the simplest causes of roof and wall leaks. When water can't drain, it backs up under shingles at the eaves, spills behind fascia boards and pours down siding next to the foundation.
What the City of Sonoma recommends
In its October 16, 2026 winter notice, the City of Sonoma asked residents to (City of Sonoma):
- Collect leaves and yard debris rather than blowing or sweeping them into the street or gutter.
- Keep gutters and drainage areas on their property clear.
- Remove leaves near a storm drain next to their property, if it's safe.
- Never try to clear a drain when water is moving rapidly or conditions are unsafe.
That advice applies across the county, especially under oaks, maples and redwoods.
Clearing gutters safely
- Use a sturdy ladder on firm, level ground, with someone holding it. Don't lean out to the side.
- Never work near overhead power lines.
- Flush downspouts with a hose to confirm they drain.
- If your roof is high, steep or wet, hire it out.
Gutters and fire season
Dry leaves in gutters are also an ember target. OSFM says embers cause 60 to 90 percent of home ignitions in wildfires (OSFM), so clean gutters help year-round.

Look while you're there
From the ladder, note any shingles that look lifted or cracked, loose drip edge or gaps at flashing. If you see problems, schedule a roof inspection. For the full prep list, see our El Niño roof prep guide.
