Rain Season in Los Angeles: Smart Home Upgrades Before the Winter Storms Hit

Los Angeles doesn’t get much rain most of the year, but when winter storms roll through, they hit fast. Gutters overflow, older roofs start leaking, and moisture sneaks into places it shouldn’t. Every year, hundreds of LA homeowners scramble for last-minute repairs right in the middle of the holidays.

If you want to avoid emergency fixes, now is the time to look at simple upgrades and small renovations that can protect your home this season. These aren’t big remodels. They’re practical, weather-ready improvements that help your home stay dry, comfortable, and ready for holiday guests.

Below are the areas you should check before the next storm hits.

1. Roof and Attic: First Line of Defense

Most homeowners don’t notice roof issues until water is already dripping on their hardwood floors. A quick inspection can save you from that headache.

Look for:

Curled or missing shingles
Soft spots or sagging
Dark patches inside the attic
Blocked or rusting flashing

If your roof is older than 15–20 years, small problems tend to show up during the first big rain of the season. Fixing weak spots now is cheaper than dealing with ceiling repairs later.

2. Gutters and Downspouts: The Most Skipped Maintenance Item

Clogged gutters send water straight into your fascia boards, siding, and foundation. Once the December storms hit, it’s hard to ignore.

Do a quick check:

Remove leaves
Make sure downspouts push water away from the home
Seal any small leaks
Add gutter guards if you’re surrounded by trees

If you have elderly parents or clients who can’t get on a ladder, this is one of the safest and smartest upgrades to handle before rain season.

3. Exterior Caulking and Weatherproofing

Small cracks around windows and doors let cold air and moisture in. You may not see the leak, but you'll feel the draft.

Seal around:

Windows
Sliding doors
Exterior trim
Utility penetrations

It’s fast, cheap, and keeps your heating bill down—especially when we hit those chilly LA nights in December and January.

4. Drainage Around the Home

LA homes weren’t designed with heavy rainfall in mind. If water pools near your foundation, it causes mold, soil movement, and even foundation cracks.

Consider:

Simple trench drains
Soil re-grading
Extending downspouts
French drains for heavy pooling

These help keep water away from the base of your home.

5. Holiday-Proofing: Getting Ready for Guests

Since many families host during December, this is also a good time to fix the “little things” that have been bothering you all year.

Quick, high-impact upgrades:

New bathroom fixtures
Better lighting
Repainting high-traffic areas
Replacing old, squeaky doors
Refreshing tile grout

They’re small upgrades, but they make a big difference when entertaining.

6. Water Damage Prevention for Older Homes

If your home was built before 1980, you're more likely to experience:

Roof leaks
Poor insulation
Drafty windows
Weak siding

These homes benefit the most from minor weather-resistant upgrades. And if you’re in a home with elderly parents or relatives, these fixes also make the space safer and more comfortable.

7. When to Call a Professional

Call a contractor if:

You see interior water stains
There’s moldy smell in the attic
Gutters are pulling away
There’s sagging drywall
Your roof looks uneven or patchy
You haven’t done maintenance in 3–5 years

Rain damage in LA can cost thousands when ignored. A quick inspection now can prevent a full renovation later.

Winter storms in Los Angeles may be short, but they’re intense. Preparing your home before the rain gives you peace of mind during the holidays and keeps your home in top shape for the new year.
