The wind came down off the San Gabriels again, the trash cans went sideways on Barranca, and half of West Covina woke up to palm fronds in the driveway. That's the Santa Ana pattern doing what it does every fall. Dry, offshore, gusting hard through the South Hills and along the foothill edge toward Glendora and San Dimas.
Here's the part homeowners miss: wind damage almost never leaks the day it happens. It's dry when the wind blows. The roof looks fine from the street. Then the first real atmospheric river parks over the SGV in December, dumps two inches in a night, and the ceiling in the back bedroom goes brown. The damage was done eight weeks earlier.
So check now, while it's still dry and while a repair is a repair instead of a repair plus drywall plus insulation plus a paint crew.
The 8-point post-wind check
You can do most of this from the ground with binoculars or a phone camera zoomed in. Please don't climb a wet or steep roof, and stay off tile entirely — walking a concrete S-tile roof wrong breaks more tile than the wind did.
- 1. Lifted or missing shingles. Look for shingles that sit slightly proud of the ones around them, or a line that's no longer straight. On a 1960s ranch tract roof, wind gets under the tab edge where the factory sealant strip has baked loose after twenty summers of SGV sun. Once one tab breaks the seal, the next storm peels its neighbors.
- 2. Ridge caps. The single most common wind casualty. Caps sit at the highest, most exposed line on the house, and on hillside lots in West Covina Hills they take the gusts straight on. Torn, cocked, or plain gone — a missing cap is an open seam down the length of your roof.
- 3. Displaced or slipped tile. Concrete and clay tile don't blow off often, but they shift, and the field tile at rakes and hips lifts. Also check the ground: a broken tile in the side yard means there's a gap on the roof, and the underlayment under it is the only thing keeping water out. That underlayment is usually the oldest, most brittle part of the whole assembly.
- 4. Debris in the valleys. Santa Anas strip eucalyptus, pepper trees, and pine right into the roof valleys, which is exactly where all your water wants to run in January. A packed valley acts like a dam and pushes water sideways under the shingle. Clear valleys and gutters before the first storm, not during it.
- 5. Exposed nail heads. Every fastener that got exposed by a lifted shingle, and every nail in a previous repair where the sealant has cracked, is a straw pointed into your attic. Sun-baked mastic on a Woodside Village roof from the last patch job is doing nothing at this point.
- 6. Flashing. Chimneys, skylights, wall-to-roof transitions, and the sheet-metal at every plumbing vent. Wind flexes flashing and finishes off sealant the summer already dried out. Look for lifted edges, gaps at the counterflashing, and pipe boots with cracked rubber collars — the boots are a classic first-rain leak.
- 7. Low-slope sections. Half the ranch stock around Merced and Cameron has a shallow-pitch section over a patio, carport, or a back addition. Those roll-roofing or cap-sheet areas hold water instead of shedding it, and wind lifts the seams. Check every seam and every edge metal.
- 8. Inside the attic. Free and fast. Go up with a flashlight during daylight and look for pinpoints of light, dark staining on the decking, or damp insulation. Daylight through the deck is the whole inspection right there.
Claim or same-day repair?
Straight answer: most post-Santa Ana calls are a repair, not a claim. A dozen lifted shingles, two ridge caps, a cracked pipe boot — that's a couple hours of work and it'll sit well under any sane deductible, and filing on it in California's current homeowners market isn't worth the file note.
A claim makes sense when the wind took a real section off, when there's structural or interior damage, or when tile and underlayment both failed across an area. In that case, photograph everything before anyone touches it, date the photos, and note the wind event. And skip the "free hail inspection" pitch that shows up door to door after a windstorm. Hail isn't the threat here. Wind, UV, and December rain are.
One more thing worth knowing: if the roof is 25+ years old and original, insurers in the SGV are getting pickier at renewal — especially near the foothill fire zones in Azusa and Arcadia, where Class A fire-rated assemblies are required. A patch keeps you dry this winter. It doesn't fix a roof that's out of years.
If you'd rather have someone else on the ladder, that's what we do across West Covina, Covina, and the rest of the valley — send us the address and we'll take a look before the rain does. Or start on the main page if you want to see what we handle.
Do the walk-around this weekend. December is closer than it feels.
