Santa Ana winds are part of life in Poway. The air turns dry, the gusts pick up, and for a day or three, everything outside gets pushed. Most homes ride it out fine. Some come out with loose parts that cause trouble later.
This is a plain walkaround to do once the wind drops. It takes under an hour on most lots.
What these winds are
The National Weather Service explains it simply. High pressure over the desert pushes air west toward lower pressure off the coast. The air flows through mountain passes and down the slopes. As it drops, it compresses and warms. That’s why Santa Anas feel hot and dry. The NWS says they’re most common from September through May and can cause major property damage.
A 2015 study by Cao and Fovell on downslope windstorms in San Diego County looked at how terrain shapes these winds. The short version: hills and foothills can see stronger gusts than flat ground nearby. Poway has plenty of both.
First, safety
- Stay clear of downed power lines. Assume they’re live.
- Don’t climb on a roof during or right after a wind event.
- If a tree is leaning on the house, keep people out of that area.
- If you smell gas or see a damaged meter, leave and call the utility.
The roof line, from the ground
Walk around the house and look up. You’re checking for:
- Missing or lifted roof tiles or shingles.
- Gutters pulled away from the fascia.
- Downspouts knocked loose or split.
- Vent caps bent or missing.
- Chimney caps or flashing out of place.
Why does this matter for a structural company? Because a loose downspout dumps the next rain right at the foundation. A gap in the roof lets water into framing. Small wind damage turns into water damage.
Patio covers, pergolas and shade structures
These catch a lot of wind. Look at each one:
- Are the posts still plumb?
- Are post bases cracked, lifted or pulled from their footings?
- Did any connection to the house wall pull loose?
- Is the cover sagging or racked out of square?
A patio cover attached to the house can pull on the wall it’s fastened to. If the ledger or connections moved, that’s worth a closer look.
Fences and garden walls
Wood fences rock in high wind. Over time, posts loosen and footings crack. Masonry garden walls don’t flex. They crack.
- Do check for fence posts that now lean.
- Do look at masonry walls for new cracks, especially at the base and near gates.
- Don’t lean anything heavy against a wall that’s already tilting.
- Don’t assume a wall is fine because it’s still standing.
If a wall also holds back soil, it’s a retaining wall. Treat cracks in it more seriously.
Trees near the house
Wind loads trees. Roots on the windward side can lift. Look for:
- A tree that leans more than it did before.
- Soil heaved or cracked on one side of the trunk.
- Broken limbs hanging over the roof.
- Roots lifted near a patio, walkway or foundation.
A large tree that’s partly uprooted near a house is a job for an arborist first.
Drains, inlets and the ground
Wind fills drains with leaves, needles and grit. The next rain then backs up around the house.
- Clear area drains, catch basins and gutters.
- Check that downspout extensions are still in place.
- Look at slopes for bare patches where wind stripped mulch or loose soil.
Dry offshore air also pulls moisture out of the ground. Clay soil can shrink. You might see new hairline cracks in flatwork or a gap at the edge of a patio. Most of that is seasonal. Note it with a dated photo and compare after the rains.
Ground-mounted equipment
Check solar arrays, AC pads, propane tanks and water tanks. Mounts should be tight. Pads shouldn’t have shifted. If something moved, find out why before the next event.
Decks and balconies
Decks don’t usually blow over. But wind pushes on railings, privacy screens and anything tall on the deck. Check:
- Railings that now wobble or lean out.
- Privacy screens or lattice pulled loose from posts.
- The ledger board where the deck meets the house. Look for new gaps or rust streaks.
- Umbrella bases or planters that slid and hit something.
A loose railing is a safety issue on its own. Fix it before anyone leans on it.
Garage doors and large openings
Big doors take a lot of wind. A garage door that bowed in during gusts can strain its track and the framing around it. After the wind, open and close it. Listen for new noises. Look for bent track or loose brackets. Check the wall around the opening for new cracks in stucco.
Getting ready for next time
The walkaround also tells you what to do before the next event. Secure loose items. Trim limbs over the roof. Tie down shade sails or take them down when strong winds are forecast. Check that patio cover connections are tight. Keep drains clear going into fall. None of it is complicated. It just has to get done before the gusts arrive, not after.
The fire side of wind season
Santa Ana days are fire days. The City’s hazard annex lists wildfire among Poway’s main hazards. If smoke or embers reached your area, check vents, under-deck spaces and crawl-space openings for debris. If fire came close, a post-fire evaluation looks at different things than a wind walkaround.
Write it down
Take photos as you go. Date them. Note anything that moved, cracked or came loose. Keep the notes with your house file. Next wind season, you’ll know what changed.
When to call
Call when a patio cover or deck connection to the house has moved, when a retaining wall has new cracks, when a tree has shifted near the foundation, or when you find damage that lets water into the structure. Some repairs may need a permit from the City’s Building Services. We coordinate with licensed engineers as needed.
What drives the scope
How exposed the lot is. The size and type of attached structures. Wall height and type. Tree size and location. Roof and drainage condition. Whether permits apply. Those factors decide the work.
