Winter Storm Prep Checklist for Inland Empire Homes (Do These Before the November Rains)

The Inland Empire packs most of its rain into a short winter window, and Murrieta is no exception — the area averages around 11 inches a year, nearly all of it between November and March. That means your home gets one dry season to prepare and then faces the whole year's rain in a few months. This checklist walks through what to do before the first November storm, grouped by area so you can knock it out in a weekend. Think of it as trading one dry-season weekend for a winter without buckets under the ceiling — a trade that pays off the very first time a storm rolls through.

Why late October is the deadline

Repairs, sealant, and roof work all go better in warm, dry weather, and they need time to cure. If you wait until the forecast shows rain, you are patching in a hurry and the fixes may not hold. Getting everything done by late October means your home is ready when the first system rolls through — which is exactly when we see the most preventable damage, because homes meet heavy rain with summer-worn roofs and clogged gutters. There is also a practical scheduling reason: roofers, gutter crews, and handymen book up the moment the first storm hits the news, so the homeowner who calls in October gets a calm appointment while the one who waits until November joins a long, anxious line.

The roof and attic

Your roof takes the first hit. Work through it before anything else:

1. Inspect for missing, cracked, curled, or lifted shingles and tiles, and have them repaired.
2. Check the flashing around chimneys, vents, skylights, and where the roof meets walls — reseal any gaps.
3. Look at the sealant around all roof penetrations and refresh it if it is cracked or brittle.
4. From inside the attic, look for daylight, water stains, or damp insulation that point to an existing leak.
5. Trim back tree branches that overhang the roof so wind cannot drive them into it.

Gutters, downspouts, and drainage

Rain on the roof has to get away from the house. Give it a clear path:

1. Clean all gutters of leaves and debris, then flush them with a hose to confirm they flow.
2. Check that gutters are pitched toward the downspouts and firmly attached.
3. Extend downspouts so they discharge at least four to six feet from the foundation.
4. Clear yard drains, area drains, and any swales of summer buildup.
5. Regrade soil that has settled so it slopes away from the house, not toward it.

Doors, windows, and the garage

These are the openings wind-driven rain exploits:

• Reseal cracked caulk around window and door frames.
• Replace worn weatherstripping so doors close tight.
• Inspect and replace the garage door bottom seal — a frequent leak point in a storm.
• Check that window wells and thresholds drain and do not pool.
• Seal gaps around exterior outlets, hose bibs, and where cables enter the wall.

Inside the house

Finish with the systems you will rely on during a storm:

1. Locate and test your main water shut-off so you can stop a burst pipe fast.
2. If you have a sump pump, pour in water to confirm it turns on and drains.
3. Check that your water heater is strapped and its connections are dry.
4. Test flashlights, and keep batteries, towels, and a wet/dry vacuum where you can reach them.
5. Store important documents in a waterproof container, up off the floor.

The three ways storm water gets inside

Almost every storm leak we see enters one of three ways, and this checklist targets all three. The first is from above — a compromised roof, where wind-lifted shingles, cracked flashing, or a failed seal around a vent lets rain into the attic and then the ceiling. The second is from the sides — wind-driven rain finding gaps around windows, doors, and the garage, or backing up under a threshold. The third is from below and around — surface water that pools against the foundation because gutters overflowed or the yard slopes the wrong way, then seeps through the slab or a wall crack. When you work the list by area, you are really closing off those three routes one at a time. Miss one and the storm will find it.

Knowing the three routes also helps you triage during a storm. If water shows up at a ceiling light, look up — that is a roof or flashing problem. If it appears along the bottom of a door or window, that is an envelope-and-seal problem. If it seeps up through the floor or along the base of an exterior wall, that is drainage. Matching the symptom to the route tells you where to put your energy first, both during the storm and when you make repairs afterward.

Have a plan for when a storm still wins

Even a well-prepped home can lose a shingle to a Santa Ana gust or take on water when a drain backs up during a downpour. When that happens, fast drying is what keeps a wet ceiling from becoming a mold problem.
