Santa Ana winds hit San Diego every fall — 50–80 mph gusts pushing offshore from the desert. Most of the damage we repair after Santa Ana events was preventable with a 30-minute walk-around in September. Here's the checklist.
1. Look for lifted or slipped tile
From the ground, scan every ridge and hip line. Tile that has slid down-slope or lifted at the leading edge is the #1 wind failure point. Any lifted tile becomes an airborne projectile at 60 mph.
2. Inspect ridge caps and hip lines
Mortar-set ridge caps often crack in the 5–10-year window. Foam-set caps last longer but eventually separate. Missing or hairline-cracked caps invite wind uplift underneath the entire ridge.
3. Check flashing at every penetration
Skylights, plumbing stacks, chimneys, HVAC curbs — the sealant around each metal flashing degrades in UV. When wind lifts a corner, driving rain follows the same path.
4. Clear gutters and downspouts
Clogged gutters back water up under the roof edge. Combined with wind-driven rain, this is where most Santa Ana leaks originate — not at damaged tile.
5. Trim overhanging branches
Anything hanging over the roof becomes a wind-driven abrasion tool. Eucalyptus and pepper trees are notorious in Rancho Santa Fe and Poway.
6. Check attic vents and gable ends
Loose vent screens and gable vents let wind-driven embers into the attic during red-flag events — the most common wildfire ignition mechanism.

Frequently Asked Questions
How do I prepare my roof for Santa Ana winds?
Have a certified inspector check ridge caps, hip closures, tile fasteners, flashing, and any lifted shingles. Trim overhanging branches, secure loose gutters, and clean debris off the roof so wind can't get under material. A pre-season tune-up is $250–$600.
Do Santa Ana winds damage tile roofs?
Tile itself is very wind-resistant, but ridge and hip caps sealed with foam or mortar can loosen over 20+ years. Wind uplift then peels caps off. A pre-season check with re-bedding of any loose caps prevents 90% of Santa Ana tile losses.
Are shingle roofs likely to fail during Santa Ana events?
Shingles older than 15 years, poorly nailed installs, and 3-tab (non-architectural) shingles are the highest risk. Modern architectural shingles installed with 6 nails per shingle carry 130 mph wind ratings and handle Santa Ana events well.
What should I do if my roof blows off during Santa Ana winds?
