The Ultimate Pre-Storm Checklist for San Diego Homeowners

When you think of San Diego, sunny skies and mild weather usually come to mind. But every year, the region faces seasonal storms—particularly during the winter months—bringing heavy rainfall, strong winds, and flash flood risks. As rare as they may seem, these storms can cause significant water damage to unprepared homes.

At RAMM Water Restoration, we’ve seen firsthand how a little preparation can prevent a lot of heartache. That’s why we created this Ultimate Pre-Storm Checklist for San Diego Homeowners—a guide to help you protect your property, your family, and your peace of mind when the next storm rolls in.

1. Inspect and Clear Your Gutters

Your gutters are your home’s first line of defense against water damage. When clogged with leaves or debris, they can’t direct rainwater safely away from your home, increasing the risk of overflow and roof leaks.

✔ Clean all gutters and downspouts ✔ Check for cracks, rust, or sagging ✔ Ensure downspouts extend at least 4–6 feet away from the home

2. Check the Roof and Flashing

A small crack or missing shingle might not seem like a big deal—until wind and rain seep through and cause costly water damage.

✔ Inspect for damaged or missing shingles ✔ Look at the flashing around chimneys and vents ✔ Consider a professional roof inspection if it hasn’t been done in the past year

3. Seal Windows and Doors

Water can easily sneak in through worn-out seals around your windows and doors, especially during wind-driven rain.

✔ Inspect caulking and weatherstripping ✔ Replace cracked or brittle seals ✔ Ensure all windows close and lock securely

4. Test Your Sump Pump (If You Have One)

Homes with basements or crawl spaces should have a working sump pump to remove water that collects during heavy rain.

✔ Test your sump pump by pouring water into the pit ✔ Make sure it activates and drains correctly ✔ Check the backup battery if your system has one

5. Trim Trees and Secure Outdoor Items

San Diego storms often bring gusty winds that can knock over trees and turn patio furniture into flying hazards.

✔ Trim back any limbs hanging near your roof or power lines ✔ Secure or bring inside outdoor furniture, umbrellas, and décor ✔ Inspect fences and gates for stability

6. Protect Low-Lying Areas and Entry Points

If your home sits on a slope or has a low entry point, it’s especially vulnerable to flooding.

✔ Install sandbags or water barriers near vulnerable doors and garage entries ✔ Check that landscaping drains water away from the home ✔ Ensure any basement windows are properly sealed

7. Prepare for Power Outages

Storms can knock out electricity. A little planning now can save you major headaches later.

✔ Charge backup batteries for flashlights and cell phones ✔ Have a battery-powered radio for weather updates ✔ Consider purchasing a portable generator for essentials

8. Safeguard Important Documents and Valuables

Water damage can ruin irreplaceable items in minutes.

✔ Store important papers in waterproof containers ✔ Elevate electronics and valuable items off the floor, especially in flood-prone areas ✔ Take photos of your property for insurance documentation

9. Turn Off Outdoor Water Sources

Before a storm, shutting off certain outdoor water lines can prevent burst pipes.

✔ Disconnect and drain hoses ✔ Shut off irrigation systems ✔ Insulate exposed pipes if temperatures are dropping

10. Know Where Your Water Shutoff Valve Is

In case of an emergency, shutting off the water quickly can limit damage.

✔ Locate and label your main water shutoff valve ✔ Make sure all household members know how to use it ✔ Check that the valve works and isn’t rusted or stuck

11. Review Your Insurance Coverage

Check that your homeowners' insurance includes flood and storm-related coverage. Not all policies cover these events, especially if you're in a low-risk area like much of San Diego.

✔ Review policy details and limits ✔ Consider supplemental flood insurance if needed ✔ Document all valuables with photos or videos
