Southern California doesn't get the blizzards or tornadoes that keep roofers in other parts of the country busy year-round. But don't let that lull you into thinking our weather is gentle on roofs. The Inland Empire has its own roster of storm events, and each one leaves a different kind of damage signature. Knowing what to look for - and doing it quickly after a storm - is the difference between a targeted repair and discovering a problem only after it's soaked through your ceiling.
The SoCal Storm Landscape
Before we get into the signs, it helps to understand what we're actually dealing with here:
Santa Ana Winds
Hot, dry winds that can gust 50–80+ mph. The #1 cause of roofing damage in the Inland Empire. They lift shingles, snap tree limbs, and break flashing seals.
Atmospheric River Rains
Rare but intense multi-day rain events that dump more water than our roofs normally see all year. They stress-test every weak point simultaneously.
Hail
Uncommon in the lower Inland Empire but not unheard of at higher elevations. Even small hail can dent soft metals and fracture granule coatings on shingles.
Wildfire Debris
Ash, embers, and airborne debris from nearby fires land on roofs and accumulate in valleys, clogging drainage and depositing acidic material that accelerates shingle wear.
Warning Signs You Need Storm Damage Repair
- Missing or blown-off shingles. The most visible wind damage sign. After a Santa Ana event, walk your property perimeter and look for shingles on the ground or in your yard. Any bare patch on the roof is an active leak risk for the next rain.
- Lifted or displaced flashing. Flashing around chimneys, skylights, and pipe vents is particularly vulnerable to high winds. It doesn't have to be completely gone to be a problem - even slightly lifted flashing allows water to work underneath during rain. Look for flashing that appears separated, buckled, or bent.
- Dented or crushed gutters and downspouts. Storm-force winds carry debris, and hail leaves visible dents. Dented gutters may seem cosmetic, but they affect drainage and can pull away from the fascia, creating water intrusion points at the roof edge.
- Debris accumulated on the roof or in valleys. Branches, palm fronds, leaves, and wildfire ash lodged in roof valleys block drainage, hold moisture, and accelerate shingle deterioration. After any major wind event, what's sitting on your roof needs to come off promptly.
- Sudden interior leaks that coincide with rain. If you didn't have a ceiling leak before a storm and you do now, the storm caused damage. Even if the roof looks okay from the ground, a post-storm leak is always reason for an immediate professional inspection. The connection between storm and symptom is direct.
- Heavy granule wash in gutters after rain. A small amount of granules in gutters is normal. After a hail storm or intense rain, a significant wash of granules - grainy, sand-like material - means the protective coating on your shingles has been stripped or jarred loose in that area.
- Bent or damaged roof vents. Metal roof vents can be dented, twisted, or completely displaced by high winds. A bent vent is no longer sealing properly and may be allowing water to enter around the perimeter of the boot or cap.
- Cracked, shifted, or shattered skylights. Skylights take direct hits from airborne debris and are a common storm damage point. Any crack, chip, or displaced frame requires immediate attention - water intrusion through a skylight is fast and damaging.
What Happens If You Wait?
Storm damage creates urgency because the next weather event uses the same weak spots. A shingle lifted by a Santa Ana wind may sit flat after the wind dies - but its seal is broken. When the atmospheric river rains arrive, water runs under that shingle freely. The next storm doesn't have to be extraordinary to cause serious damage through the entry points the first one created.
There's also an insurance timeline to consider. California homeowners insurance policies typically require that you report damage and mitigate further loss promptly. If you wait months to address obvious storm damage, an adjuster may argue that subsequent damage wasn't caused by the original storm - complicating or reducing your claim.
If you believe your storm damage may be covered by homeowners insurance, document everything with photos before any work is done. Walk around the property, photograph the roof from the ground, and take photos of any interior water damage. This documentation supports your claim and establishes the timeline of damage.
When to Call a Professional
After any significant storm event, the right move is a professional post-storm inspection - especially if you have any of the signs above, or even if you don't. Some storm damage is only visible to a trained eye on the roof surface. Wind-broken shingle seals look normal from the ground. Lifted flashing looks intact until you're standing on the roof. The inspection catches what your ground-level scan can't.
For emergency situations - active leaks, large sections of missing roofing, or visible structural damage - call us immediately. We handle storm damage emergencies throughout the Inland Empire and can get tarps down and emergency repairs made quickly to stop active damage.
Within same-day of a significant wind or rain event, check your gutters for debris and granules, walk the perimeter looking for shingles on the ground, look at your ceiling for new staining, and check your attic with a flashlight for any new light or moisture. If anything is new or changed, it warrants a call. This five-minute walk-around has saved many of our customers from discovering storm damage only through a ceiling collapse.
