Bay Area winters may not bring the snow and ice of colder climates, but they do bring intense atmospheric river storms, heavy rainfall, and high winds that can cause serious damage to homes that aren’t properly prepared. Every year, restoration companies see a surge in water damage calls during storm season, much of it preventable with some basic preparation before the rain arrives.
Dry 1 Out Restoration and Construction has responded to countless winter storm damage emergencies across the Bay Area and San Diego County. In this guide, we’ll cover the most important steps homeowners can take to prepare their property for winter storm season, along with what to do if damage occurs despite your best efforts.
Much of the Bay Area’s rainfall arrives in concentrated bursts during atmospheric river events, which can dump several inches of rain in a very short period. Homes that go months without significant rainfall during the dry season often have gutters clogged with debris, roofs with unnoticed wear and tear, and drainage systems that haven’t been tested against a real storm in a long time. This combination of infrequent heavy rain and aging or neglected drainage infrastructure is exactly why so many Bay Area homes experience water intrusion during winter storms.
Clogged gutters are one of the leading causes of water damage during storm season. When leaves, debris, and dirt block the flow of water, rain can back up under roof shingles or overflow directly against your home’s foundation. Before storm season begins, clean out all gutters and downspouts, and make sure downspouts direct water at least several feet away from your foundation.
A roof inspection before the rainy season can catch small problems before they become major leaks. Look for missing, cracked, or curling shingles, damaged flashing around chimneys and vents, and any visible sagging in the roofline. If you’re not comfortable inspecting your own roof, a professional inspection is a worthwhile investment before winter storms arrive.
Worn weatherstripping and deteriorated caulking around windows and doors allow wind-driven rain to seep into your home. Inspect all exterior seals and reapply caulk or weatherstripping where needed, particularly around older windows and doors that see the most wear over time.
The ground around your foundation should slope away from your home to direct water away naturally. If you notice water pooling near your foundation after rain, consider regrading the soil or adding drainage solutions like French drains to redirect water flow before it can seep into your basement or crawl space.
If your home has a sump pump, test it before storm season to make sure it’s functioning properly. Pour water into the sump pit to confirm the pump activates and drains correctly. Consider a battery backup system as well, since power outages are common during major storms, exactly when you need your sump pump working most.
High winds during winter storms can snap weak or dead branches, sending them into roofs, windows, and power lines. Trim back any branches hanging over your roof and remove dead or diseased trees that could pose a risk during a major storm.
Small cracks in your foundation can become significant water entry points during heavy rain. Walk the perimeter of your home and inspect the foundation for any visible cracks, and seal minor ones before the rainy season begins. Larger cracks may require professional evaluation and repair.
In addition to preparing your home’s structure, it’s wise to prepare for potential power outages and flooding. Keep flashlights, batteries, a battery-powered radio, and basic supplies on hand. Know where your main water shutoff valve is located in case of a plumbing emergency during the storm, and keep the contact information for a trusted restoration company readily available.
If your home has a basement or ground-floor storage area prone to flooding, consider elevating stored items on shelves or platforms rather than leaving them directly on the floor. This simple step can prevent significant loss if water does find its way inside during a major storm.
Before storm season arrives, review your homeowner’s insurance policy to understand exactly what is and isn’t covered. Standard policies often exclude flood damage, which typically requires a separate flood insurance policy. Understanding your coverage ahead of time means one less thing to worry about if damage does occur.
Even with the best preparation, severe storms can still cause water damage. If you experience flooding, a roof leak, or other storm-related water intrusion, it’s important to act quickly. Shut off electricity to affected areas if it’s safe to do so, document the damage with photos and video for your insurance claim, and contact a professional restoration company as soon as possible. The longer water sits, the greater the risk of mold growth and structural damage, so a fast response in the hours after a storm can make a significant difference in your total repair costs.
