How to Spot Hidden Exterior Damage After a Midwest Storm

• Hail can bruise shingles without knocking them off

• Wind can loosen flashing or seals without tearing materials away

• Heavy rain can push water into small gaps that later cause leaks

By the time interior signs appear, the damage has often been there for a while.

Hidden Roof Damage to Watch For

Your roof takes the brunt of storm impact, and problems aren’t always obvious.

Hail Bruising on Shingles

Hail can knock granules off asphalt shingles or create soft “bruised” spots that weaken them. These areas may:

• Look slightly darker

• Feel soft or spongy under gentle pressure (inspection by a professional is safest)

• Shorten the lifespan of the roof

Bruised shingles often fail prematurely during the next freeze-thaw cycle.

Lifted or Loosened Shingles

Strong winds can break the seal that holds shingles in place without tearing them off. This creates gaps where water can enter during future storms.

Signs from the ground may include:

• Uneven or lifted shingle edges

• Tabs that appear misaligned

Even small lifting can lead to long-term leaks.

Flashing Damage

Flashing around chimneys, vents, skylights, and roof valleys is especially vulnerable.

Wind and debris can bend or loosen flashing, allowing water to seep into roof decking and wall cavities. Flashing issues are a common source of hidden leaks.

Siding Damage That Isn’t Immediately Visible

Storm damage to siding often looks minor at first but can allow moisture behind wall systems.

Hairline Cracks and Impact Marks

Hail or flying debris may leave small cracks, chips, or dents in siding. These openings can:

• Allow water infiltration

• Expand over time due to freeze-thaw cycles

• Lead to mold or rot behind walls

Even tiny cracks can become serious if ignored.

Loose Panels After High Winds

Strong winds can pull siding panels slightly away from the wall without fully detaching them. Gaps at seams or corners allow wind-driven rain to enter.

Walk around your home and look for:

• Panels that look uneven

• Sections that rattle in the wind

• Gaps near trim or corners

Window and Door Warning Signs

Storms often stress seals around windows and doors.

Failed Caulking or Sealant

Heavy rain and wind pressure can weaken caulking. Over time, this leads to:

• Drafts

• Water intrusion

• Rotting trim

Look for cracked, peeling, or missing sealant around frames.

Subtle Interior Clues

Sometimes the first signs of exterior damage appear indoors:

• Water stains near windows

• Peeling paint or bubbling drywall

• Musty odors

These can indicate water entering through compromised exterior seals.

Gutter and Drainage Issues After Storms

Gutters often show obvious storm damage, but some issues are easy to overlook.

Hidden Gutter Misalignment

Wind and debris can shift gutters slightly out of alignment, reducing drainage performance.

Signs include:

• Water overflowing in areas that previously drained well

• Gutters pulling away slightly from fascia boards

Poor drainage can send water behind siding or toward the foundation.

Downspout Disconnections

High winds or falling branches may loosen downspouts, causing water to spill near the home instead of flowing away.

This can lead to foundation moisture issues that appear long after the storm.

Foundation and Ground-Level Signs

Stormwater can cause problems at the base of the home.

New Soil Erosion

Heavy rainfall may wash soil away from the foundation, reducing proper grading and allowing water to pool.

Damp Basement Walls

Moisture in the basement after storms may point to exterior drainage or foundation issues rather than interior plumbing problems.

Why Hidden Damage Gets Worse Over Time

Even small storm-related issues can escalate.

For example:

• A lifted shingle allows minor water entry

• Repeated rain soaks roof decking

• Mold or rot develops

• Interior leaks appear months later

Midwest freeze-thaw cycles can rapidly worsen hidden cracks and gaps.

When to Schedule a Professional Inspection

Because many storm-related issues are difficult to see safely from the ground, it’s wise to have a professional inspection after:

• Hailstorms

• High-wind events

• Heavy, prolonged rainfall

Professionals can safely examine roofing, flashing, siding, and drainage systems for subtle damage.

Preventing Future Problems

After storms, taking a proactive approach helps prevent hidden issues from spreading.

• Clear debris from gutters and downspouts

• Check attic and ceilings for new stains

• Monitor for drafts or unusual moisture

• Address small repairs promptly

Early action helps protect your home from long-term structural damage.

Frequently Asked Questions

Can hail damage a roof without visible holes?

Yes. Hail can bruise shingles and weaken them without causing immediate leaks.

Should I check my attic after storms?

Yes. Look for new water stains, damp insulation, or musty smells.

Is siding damage always obvious?

No. Small cracks or loosened panels can be easy to miss.

Do gutters need inspection after every storm?

It’s a good idea after severe storms, especially with heavy rain or wind.

Can hidden damage affect home value?

Yes. Undetected moisture and structural issues can reduce long-term property value.
