High winds are common throughout Southern California, especially in the Inland Empire, where cities like Hemet, San Jacinto, Menifee, Lake Elsinore, Perris, Moreno Valley, and Beaumont often experience strong gusts during seasonal storms and Santa Ana wind events that can cause significant wind damage to your roof.

Wind damage to a roof isn’t always obvious right away. Even when there’s no active leak, wind can loosen materials, expose vulnerable areas, and weaken the roofing system in ways that may lead to more serious problems over time.

Wind damage to a roof most commonly includes lifted shingles, damaged ridge caps, loose flashing, and granule loss. Even without visible leaks, wind damage can compromise the roof’s protective layers and allow water intrusion during future storms if left unaddressed.

Below are five important things homeowners should check after a windstorm.

How can you tell if you have wind damage to your roof?

You can often spot wind damage by looking for lifted or uneven shingles, missing roofing materials, or debris around your property. Some forms of wind damage are subtle and may not be visible from the ground, which is why inspections after strong winds are important, especially for older roofs.

1. Lifted or Creased Shingles

One of the most common results of high winds is shingles that have lifted or partially detached. Even if shingles haven’t blown off completely, wind can break the adhesive seal that keeps them secure.

Things to look for:

• Shingles that appear uneven or no longer lie flat

• Creases or bends along shingle edges

• Shingles that move easily when lightly touched

Why this matters: once shingles lose their seal, they become far more vulnerable to future wind and rain, accelerating roof deterioration.

2. Missing or Damaged Ridge Caps

Ridge caps run along the peaks of your roof and are often the first area affected by strong winds. In Inland Empire communities where wind funnels through open terrain and hills, ridge cap damage is especially common.

Check for:

• Missing ridge cap shingles

• Gaps or uneven areas along the ridgeline

• Roofing material found in the yard or gutters

Damage at the ridge can allow moisture to enter the roof system more easily.

3. Loose or Damaged Flashing

Flashing protects areas around chimneys, vents, skylights, and roof edges. Wind can bend, lift, or loosen flashing even if surrounding shingles appear intact.

Warning signs include:

• Visible gaps around roof penetrations

• Bent or lifted metal flashing

• Sealant that appears cracked or pulled away

Why this matters: flashing failures are one of the most common causes of roof leaks following windstorms.

4. Granule Loss on Asphalt Shingles

Asphalt shingles rely on granules to protect against sun exposure and weathering. High winds can accelerate granule loss, especially on older roofs.

Look for:

• Excessive granules in gutters or at downspout exits

• Bald or discolored areas on shingles

• Granules collecting around the home’s perimeter

Granule loss shortens the lifespan of shingles and leaves them more vulnerable to UV damage.

5. Subtle Interior Warning Signs

Not all wind damage is immediately visible outside. In some cases, the first signs appear inside the home days or weeks later.

Watch for:

• New water stains on ceilings or walls

• Unexplained drafts or temperature changes

• Moisture or unusual odors in the attic

These signs may indicate wind-related roof damage that should be professionally evaluated.

How Wind Damage Affects Different Roofing Types

Wind impacts roofing materials differently depending on how the roof system is designed, installed, and aged. In the Inland Empire, we commonly see wind damage across several roofing types.

Asphalt Shingle Roofs
Asphalt shingles are the most common roofing material in Southern California. High winds can break the adhesive seal that holds shingles in place, leading to lifting, creasing, or complete blow-offs. Older shingles are especially vulnerable once granule loss has begun.

Tile Roofs (Concrete or Clay)
Tile roofs are durable but not immune to wind. Strong gusts can shift or crack individual tiles, particularly along ridges, hips, and edges. Displaced tiles may expose the underlayment beneath, allowing water intrusion during future storms.

Flat and Low-Slope Roofs (TPO, Modified Bitumen, Built-Up Roofing)
On flat or low-slope roofs, wind damage often shows up as lifted seams, loose edge metal, or membrane movement. These issues may not be immediately visible but can compromise the roof’s waterproofing over time.

Metal Roofing
Metal roofs generally perform well in high winds, but fasteners, seams, and flashing remain critical points of failure. Aging components or improperly secured panels can loosen under sustained wind pressure.

Understanding how wind affects different roofing systems helps homeowners recognize potential issues and determine when a professional inspection is needed.

Why Wind Damage Shouldn’t Be Ignored

Wind damage often starts small but worsens over time. A lifted shingle or loose flashing may not cause immediate problems, but future rain or wind events can quickly turn minor issues into costly repairs.

Addressing the wind damage to your roof early can help:

• Prevent water intrusion

• Protect underlying roofing materials

• Extend the life of your roof

• Reduce overall repair costs

This is particularly important in Southern California, where windy conditions are often followed by rain.

Wind Damage and Insurance Considerations

Homeowners insurance may cover certain types of wind or storm-related roof damage, depending on the policy and the condition of the roof. Proper documentation is essential.

The California Department of Insurance provides guidance on homeowners insurance coverage and claims.

After a windstorm:

• Take photos of visible damage

• Note the date and weather conditions

• Avoid permanent repairs before documentation

• Schedule a professional inspection if damage is suspected

When to Schedule a Professional Roof Inspection

You should consider a roof inspection if:

• Your home experienced strong or sustained winds

• Roofing debris is visible around the property

• Your roof is older or nearing the end of its expected lifespan

• You’re unsure whether damage occurred

A professional inspection can identify issues that aren’t visible from the ground and help you understand your options moving forward.

Key Takeaways About Wind Damage to Your Roof

• Wind damage isn’t always immediately visible

• Lifted shingles and loose flashing are common problems

• Small issues can worsen over time if ignored

• Early inspections can help reduce repair costs

Final Thoughts

High winds are a regular part of life in the Inland Empire, but roof damage doesn’t always announce itself right away. Wind damage to your roof can worsen over time if minor issues are left unaddressed. Taking the time to check your roof after a windstorm — or having it professionally inspected — can help protect your home and avoid unexpected repairs down the road.

If you’re concerned about possible wind or storm damage, scheduling an inspection is the best way to understand your roof’s condition and plan next steps with confidence.
