How to Prep Your Home for Winter in Santa Rosa

Winter in Santa Rosa isn’t harsh like the Midwest, but the rains can do serious damage if a home isn’t properly maintained. A few proactive steps now can protect your roof, prevent costly leaks, avoid drainage issues, and keep your HVAC running efficiently all winter long.
Here’s a simple, homeowner-friendly guide to get your property ready.

1. Inspect Your Roof Before the First Major Rain

Santa Rosa gets consistent winter storms, and even small roof issues can turn into big problems fast.

What to do:

• Look for cracked, curled, or missing shingles.

• Check flashing around chimneys, vents, and skylights.

• Inspect for soft spots that could indicate moisture intrusion.

• Have a licensed roofer do a quick pre-winter inspection — it’s cheaper than repairing water damage.

Why it matters:
Roof leaks are one of the top winter repair calls in Sonoma County, and nearly all of them were preventable with basic pre-season maintenance.

2. Clean Out Your Gutters & Downspouts

Clogged gutters cause water to spill over and saturate the areas closest to your home — the exact opposite of what you want.

Make sure to:

• Remove leaves, needles, and roof debris.

• Run water through downspouts to confirm flow.

• Ensure downspouts extend several feet away from the foundation.

• Consider gutter guards if you’re surrounded by trees.

Why it matters:
Overflowing gutters are a leading cause of foundation issues, siding rot, and attic moisture — especially after those big Santa Rosa storms.

3. Check Your Drainage System

With the soil getting saturated quickly in winter, poor drainage can lead to pooling water, foundation movement, or even interior flooding.

Steps to take:

• Walk around your property after a light rain to spot where water collects.

• Make sure soil slopes away from your home’s foundation.

• Clear French drains, yard drains, and landscape drains.

• Have a landscaper re-grade problem areas if water is pooling.

Why it matters:
Water always finds a path — good maintenance ensures it doesn’t find its way into your crawl space or living room.

4. Service Your HVAC System

Once temperatures drop, you want your heater operating efficiently and safely.

Do this before winter:

• Change the HVAC filter (most homeowners skip this!).

• Have a technician inspect the furnace for safety and efficiency.

• Check for carbon monoxide risks.

• Clean vents and registers.

• Program your thermostat for winter settings.

Why it matters:
A serviced system uses less energy, keeps bills lower, and reduces the risk of your heater failing on the coldest night of the year.

5. Seal Doors, Windows & Draft Points

Keeping warm air inside and cold air out is key to lowering heating bills.

Seal the leaks:

• Replace worn or cracked weatherstripping.

• Use caulking around window frames.

• Check door sweeps and thresholds.

• Look for gaps around pipes or wiring.

Why it matters:
Small drafts add up to big energy losses — especially with PG&E rates.

6. Protect Exterior Pipes & Irrigation

Your irrigation system, outdoor faucets, and exposed plumbing can freeze during cold snaps.

Pre-winter steps:

• Insulate exposed pipes.

• Cover hose bibs.

• Shut off and drain irrigation systems if necessary.

• Disconnect hoses from faucets.

Why it matters:
A burst pipe can cost thousands — winterizing your exterior plumbing takes minutes.

7. Test Smoke & Carbon Monoxide Detectors

Heaters run longer in winter, fireplaces get more use, and windows stay closed — safety checks are essential.

Checklist:

• Test all smoke detectors.

• Replace batteries if needed.

• Make sure you have CO detectors on every level of the home.

Why it matters:
Preventing an emergency is always easier than responding to one.

Final Thoughts
