How To Spot Hail And Wind Damage On Your Roof After A Storm
This article explains how to identify hail and wind damage on a residential roof after a storm, covering visible signs such as missing granules, impact marks, cracked shingles, lifted edges, and bent flashing. It describes how to conduct a safe ground-level inspection, locate hidden interior moisture damage, distinguish storm damage from normal aging, and decide between roof repair and full replacement. Written for Michigan homeowners, the guide also outlines documentation steps for insurance claims and when to contact a professional roofing contractor.
Overview
Storm damage to a residential roof does not always produce an immediately visible hole or active leak. Hail can bruise and fracture asphalt shingles, displacing the protective granule layer and exposing the underlying asphalt to accelerated weathering. Wind can lift shingle edges, break adhesive seals, crease tabs, or remove sections of roofing entirely. In both cases, damage that appears minor from the ground can allow water to penetrate the roof system during subsequent rainfall, reaching the decking, insulation, ceilings, and interior walls.
Homeowners frequently delay action until a visible interior leak appears. However, leaks can develop weeks or months after the originating storm event, by which time secondary moisture damage may already be widespread. A prompt post-storm inspection — conducted safely from the ground and followed by a professional evaluation — is the most reliable way to catch damage before it compounds.
Veteran Roofing & Exteriors serves Michigan homeowners with storm damage assessments that cover the complete exterior system, including roofing, siding, gutters, fascia, soffits, windows, and doors.
What To Check Immediately After A Storm
Ground-Level Inspection
After the storm has fully passed, walk the perimeter of the property and look for physical evidence of displaced roofing materials. Key indicators include:
- Shingles or shingle fragments in the yard or driveway
- Roofing granules accumulated near downspout outlets
- Bent, detached, or dented gutter sections
- Pieces of flashing, fascia, or soffit on the ground
- Tree limbs or large debris near the roofline
- Dents on metal outdoor surfaces such as AC units, vents, or mailboxes
- Torn window screens or damaged siding panels
The presence of these materials confirms that roofing components have been displaced and that a closer inspection is warranted.
Safe Visual Inspection From The Ground
Binoculars or a smartphone camera with zoom capability can be used to examine the roof surface without climbing. Look for:
- Uneven or broken shingle rows
- Exposed underlayment or roof decking
- Raised or lifted shingle edges
- Damaged or dislodged ridge caps
- Bent or loose metal flashing components
Do not walk on a storm-damaged roof. Wet surfaces, loose shingles, hidden soft spots, and steep pitch angles all create serious fall hazards. Professional contractors use appropriate safety equipment for rooftop evaluation.

What Hail Damage Looks Like On Asphalt Shingles
The appearance of hail damage varies based on hailstone size, wind direction, the age of the shingles, and their pre-storm condition. The most common indicators are:
Dark Or Circular Impact Marks
Fresh hail strikes leave round or irregular dark spots where granules have been knocked away. The exposed asphalt beneath appears darker than the surrounding surface. When inspected by a professional, some impact points feel soft or spongy, indicating that the shingle mat has been compressed or fractured internally.
Concentrated Granule Loss
Granules protect asphalt shingles from UV exposure, moisture, and thermal cycling. Hail displaces them in concentrated clusters, creating bare patches that age more rapidly than the rest of the surface. Gutters and downspout outlets often collect large volumes of granules after a hailstorm. While some granule loss occurs naturally on older roofs, a sudden, concentrated increase following a storm requires professional evaluation.
Cracks, Bruises, And Broken Edges
A hailstone can damage the internal structure of a shingle without creating an immediate water-entry point. Fractures and bruises tend to expand as the shingle material expands and contracts through seasonal temperature changes. Physical signs include:
- Small cracks radiating from impact points
- Broken shingle corners or tab edges
- Exposed asphalt beneath the granule surface
- Split or cracked shingle tabs
- Indented or compressed areas on the shingle surface
Hail also commonly dents metal components including gutters, roof vents, and flashing. See: How Hail Damage Affects Siding, Gutters, And Roof Vents.
What Wind Damage Looks Like On A Roof
Wind damage is most pronounced at roof edges, ridges, corners, and other locations where air pressure differentials can lift or peel roofing materials. Shingles may be missing entirely or may appear in place while their adhesive bonds have already failed.
Missing Or Displaced Shingles
Missing shingles are among the clearest indicators of wind damage. The affected area may show bare roof decking, exposed underlayment, or an irregular break in the shingle pattern. Even a small exposed section requires prompt attention, as water can migrate laterally beneath adjacent shingles and reach the decking below.
Lifted Or Creased Shingles
Wind can lift a shingle and allow it to settle back into its original position, leaving the roof appearing intact while the adhesive seal is broken. Indicators of a lifted shingle include:
- A raised or curled lower edge
- A horizontal crease across the shingle body
- Torn material at or near fastener points
- A visible gap between shingle courses
- Movement or flutter during subsequent wind events
A shingle that has been sharply creased by wind uplift may no longer provide reliable weather protection, even if it has not separated from the roof.
Bent Flashing And Damaged Roof Edges
High winds loosen flashing at chimneys, skylights, wall intersections, valleys, and roof vents. Drip edges, ridge caps, soffits, fascia boards, and gutter attachments are also vulnerable. Flashing and edge components direct water away from joints and transitions in the roof system. A loosened or bent section allows water to migrate beneath the roof covering even when adjacent shingles remain visually intact.
How To Find Hidden Storm Damage Inside The Home
Interior evidence of storm damage may develop gradually and is not always located directly below the damaged roof section. Water can travel along roof decking, rafters, pipes, or insulation runs before becoming visible.
Attic Inspection
Using a flashlight, inspect the attic for:
- Wet or compressed insulation
- Darkened or stained roof decking
- Water trails or streaks along rafter members
- Damp areas around pipe penetrations or vents
- Daylight visible through the roof structure
- Musty or mildew odours
Ceiling And Wall Inspection
In interior living spaces, inspect upper-floor ceilings, exterior walls, areas near skylights, and chimney surrounds for:
- New water stains or discolouration
- Bubbling or peeling paint
- Soft or bowed drywall
- Efflorescence or mineral deposits near masonry
Water near electrical wiring or light fixtures requires urgent attention. Do not touch wet electrical components.

Distinguishing Storm Damage From Normal Roof Aging
Characteristics Of Normal Aging
Aging-related deterioration typically presents as:
- Widespread, gradual granule loss distributed evenly across the roof surface
- General fading or discolouration without concentrated impact marks
- Brittle or curling shingle edges
- Worn or cracked sealant
- Previous repair patches
These conditions develop over years and are not typically linked to a specific weather event.
Characteristics Of Recent Storm Damage
Storm damage tends to be more sudden in onset and directionally consistent with the wind or hail trajectory. Indicators include:
- Newly missing shingles
- Sharp creases or tears with clean, unweathered edges
- Clean exposed asphalt at impact points
- Concentrated impact marks grouped on one or two roof slopes
- Fresh dents on metal surfaces with no oxidation
- New interior water stains coinciding with the storm date
- Damage pattern correlating with prevailing wind direction
An older roof may exhibit both conditions simultaneously. A professional inspection process separates recent storm damage from pre-existing deterioration and assesses whether the remaining materials are still functional.
What To Do After Finding Possible Roof Damage
Document The Damage
Photograph each affected side of the home with wide-angle shots, then capture close-up images of visible dents, missing materials, staining, and debris. Record the date the storm occurred and the date each observation was made. Thorough documentation supports the storm damage insurance claim process.
Protect The Interior
Move furniture and belongings away from active leaks. Place containers under drip points and avoid areas where ceilings show signs of sagging. Do not attempt to install a tarp on a wet, damaged, or structurally compromised roof without proper equipment and training.
Schedule A Professional Inspection
Do not complete permanent repairs until the full scope of damage has been assessed. Partial or premature repairs may obscure underlying damage, complicate insurance claims, or leave adjacent weakened areas unaddressed.
Repair Versus Replacement: Key Considerations
Conditions Where Repair Is Appropriate
- Damage is confined to a small, isolated section
- Surrounding shingles remain flexible, intact, and properly adhered
- The roof deck is dry and structurally sound
- Flashing damage is isolated and not systemic
- Matching replacement materials can be correctly integrated with existing components
Conditions Where Replacement Is Appropriate
- Multiple roof slopes show damage
- Large numbers of shingles are lifted, cracked, or granule-depleted
- Extensive sections are missing
- The roof has significant pre-existing age-related wear
- Moisture has reached the roof decking
- Repeated prior repairs have already been completed on the same system
A professional roof inspection evaluates shingles, underlayment, flashing, ventilation, roof edges, and structural conditions. Connected exterior components — including siding, gutters, fascia, and soffits — should also be assessed as part of the same evaluation.
