Signs of storm damage on a roof are not always obvious — and that is exactly what makes storm damage so dangerous for homeowners in Northeast Pennsylvania. A severe storm can pass through Wayne, Pike, Monroe, or Lackawanna County and leave behind damage that looks minor from the ground but is quietly letting water into your home with every rain that follows.
Pennsylvania storms are no joke. Between spring hailstorms, summer thunderstorms with high winds, and the brutal freeze-thaw cycles of NEPA winters, roofs here face some of the most punishing weather conditions in the country. Knowing what to look for after a storm can be the difference between a simple repair and a full roof replacement — and it can mean thousands of dollars saved on interior water damage.
At Wallenpaupack Roofers, we inspect storm-damaged roofs across NEPA every season. In this guide, we walk you through the 10 most important signs of roof storm damage — what they look like, why they matter, and what to do when you find them.
Why Storm Damage Is Often Invisible from the Ground
One of the biggest mistakes Pennsylvania homeowners make after a storm is walking outside, looking up at the roof, and concluding that everything looks fine. The reality is that some of the most serious forms of storm damage — granule loss from hail, lifted flashing, cracked underlayment, and saturated insulation — are completely invisible from street level.
This is why a professional post-storm roof inspection matters, even if your roof looks undamaged from below. Hidden damage that goes undetected for a single season can allow moisture to penetrate the roof deck, rot structural framing, and cause mold growth inside your attic — all without a single visible water stain on your ceiling until the damage is already extensive.
With that said, there are signs you can look for yourself — safely, from the ground — that should prompt you to call a licensed roofing contractor for a proper inspection.
10 Signs of Storm Damage on a Roof
1. Missing or Displaced Shingles
This is the most visible and immediate sign that a storm has affected your roof. High winds — particularly those above 45 to 55 miles per hour — can lift, crack, or completely tear away asphalt shingles, leaving sections of your roof deck exposed to the elements.
Walk around the perimeter of your home and look for shingles on the ground, in your yard, or in gutters. Use binoculars to scan the roofline without climbing up. Even one or two missing shingles create an entry point for water and should be repaired immediately.
What to do: Do not wait. Missing shingles will allow water infiltration with the very next rainfall. Call Wallenpaupack Roofers for a same-day assessment.
2. Granule Loss on Asphalt Shingles
Granule loss is one of the most overlooked signs of storm damage on a roof, yet it can significantly reduce the lifespan of your roofing system. Asphalt shingles are coated with protective granules that help shield the roof from UV rays, harsh weather conditions, and fire hazards. When homeowners inspect for signs of storm damage on a roof, checking for granule loss is an important step that should not be ignored.
Hail impacts and strong winds often cause visible signs of storm damage on a roof by knocking these protective granules loose. As the granules disappear, the underlying asphalt becomes exposed to sunlight, moisture, and temperature fluctuations, causing shingles to deteriorate much faster.
One of the easiest ways to identify signs of storm damage on a roof is by examining your gutters and downspout drainage areas after a storm. If you notice large amounts of dark, sand-like granules collecting in these areas, it may indicate that your shingles have suffered hail or wind damage. Excessive granule loss is a clear warning sign that your roof’s protective barrier is weakening and may require professional inspection.
Because granule loss often leads to premature shingle failure, homeowners who discover this common signs of storm damage on a roof should contact a roofing professional promptly. Early repairs can help prevent leaks, extend roof lifespan, and avoid more costly roofing issues in the future.
What to do: Granule loss is one of the most common reasons insurance companies approve storm damage claims. Document what you find and call for a professional inspection before contacting your insurer.
3. Dented, Cracked, or Bruised Shingles
Hailstones cause a distinctive type of damage to asphalt shingles: circular impact marks, or bruises, where the shingle has been fractured beneath the surface. Unlike granule loss, hail bruising is not always visible from the ground and requires a close-up inspection.
On metal roofing, gutters, flashing, and vents, hail leaves visible dents that are easy to identify. If your gutters, downspouts, or AC unit covers show denting after a storm, your roof very likely sustained hail damage as well, even if it is not immediately visible.
What to do: Document any denting you can photograph from the ground. A professional roofing inspector can identify hail bruising on shingles that homeowners cannot see from below.
4. Damaged, Lifted, or Missing Flashing
Damaged flashing is one of the most serious signs of storm damage on a roof because it protects the areas most vulnerable to water intrusion. Flashing is the thin metal material installed around chimneys, skylights, roof vents, dormers, and valleys to create a watertight seal. When checking for signs of storm damage on a roof, flashing should always be inspected carefully, as even minor damage can lead to significant leaks.
Strong winds and severe storms can create obvious signs of storm damage on a roof by lifting, bending, or peeling flashing away from the surface it protects. Hail can also dent, crack, or puncture flashing, reducing its ability to direct water away from vulnerable roof areas. Once flashing becomes damaged or displaced, water can penetrate beneath the roofing system and enter the roof structure, leading to leaks, wood rot, mold growth, and costly repairs.
Because flashing damage is not always visible from the ground, homeowners who notice other signs of storm damage on a roof should schedule a professional inspection. Identifying and repairing damaged flashing early can prevent water intrusion and help protect the overall integrity of the roof.
What to do: Look for bent, lifted, or separated metal strips around your chimney, vents, and roof edges. Flashing damage is a high-priority repair regardless of season.
5. Sagging or Soft Spots on the Roof Surface
If sections of your roof appear to be sagging, dipping, or noticeably uneven after a storm, this is a serious structural warning sign. Sagging indicates that the roof deck or underlying rafters may have been compromised — either by the weight of debris, the impact of a fallen tree limb, or long-term water saturation that a storm has accelerated.
Do not attempt to inspect sagging areas of a roof yourself. This is a safety risk that requires immediate professional evaluation.
What to do: Call Wallenpaupack Roofers for emergency roofing services. Structural sagging after a storm requires same-day attention to prevent collapse or further damage.
6. Water Stains on Interior Ceilings or Walls
Brown or yellow staining on your ceilings and walls is a sign that water has already penetrated your roof system and traveled through the structure of your home. By the time staining appears inside, the roof has usually been leaking for some time — the storm may have worsened an existing weak point or created a new entry for water.
Check your attic after every major storm. Use a flashlight to look for dark staining on the underside of the roof deck, wet insulation, and mold growth on rafters. Catching this early prevents structural rot and eliminates costly remediation work.
What to do: Interior water staining should be investigated immediately. Do not assume the storm is the only cause — a professional inspection will identify both the entry point and the full extent of moisture penetration.
7. Damaged or Clogged Gutters
One of the most common signs of storm damage on a roof involves the gutter system. Gutters are an essential part of your roofing system, and damage to them can significantly affect how well your roof drains water after severe weather. When inspecting for signs of storm damage on a roof, look for gutters that are bent, detached from the fascia, cracked at the seams, or filled with debris and shingle granules following a storm.
Damaged gutters are often overlooked signs of storm damage on a roof, but they can lead to serious problems if left unaddressed. Gutters that cannot drain water properly may cause water to back up beneath the roofline, increasing the risk of roof leaks, fascia rot, and ice dam formation during NEPA winters. In addition, dented or damaged gutters are among the clearest signs of storm damage on a roof caused by hail. Identifying these warning signs early can help homeowners prevent costly repairs and protect the long-term performance of their roofing system.
What to do: Clear debris from gutters after every major storm and inspect them for structural damage. If you find large amounts of granules in your gutters, schedule a roof inspection immediately.
8. Fallen Tree Limbs or Impact Debris on the Roof
NEPA’s wooded landscape means that storm winds frequently send tree limbs onto residential roofs. Even a small limb can crack shingles, dent metal components, puncture underlayment, or damage the structural deck if it falls with enough force.
Even if the limb appears to have landed softly or caused no visible damage, the impact may have fractured shingles or cracked flashing in ways that only become apparent during a professional inspection. Do not assume no visible damage means no actual damage.
What to do: Remove debris carefully from ground level if possible and safe. Have the roof professionally inspected anywhere debris made contact, regardless of how minor the impact appears.
9. Damaged or Exposed Roof Vents and Pipe Boots
Roof vents, pipe penetrations, and rubber pipe boots are common entry points for water after storm events. High winds can crack or dislodge vent caps, and hail can crack the rubber collars around pipe boots — creating gaps that allow rainwater to run directly into the attic.
These are small components that are easy to overlook during a visual inspection from the ground, but they are a frequent source of post-storm leaks. A professional roofing inspector will check every penetration point as part of a thorough storm damage assessment.
10. Ice Dams and Snow Load Damage in Winter Storms
For Northeast Pennsylvania homeowners, winter storms bring a specific type of roof damage that warmer-climate homeowners never face: ice dams. Ice dams form when heat escaping from your home melts snow on the upper portions of the roof, which then refreezes at the colder eaves. The resulting ice barrier traps meltwater on the roof surface, forcing it under shingles and into the structure below.
Signs of ice dam damage include icicles along the eave line, water staining directly above exterior walls on interior ceilings, and lifting or cracked shingles at the lower portions of the roof. Proper attic insulation and ventilation are the long-term solution, but emergency ice dam removal is sometimes necessary to protect the roof mid-winter.
What to do: If you suspect ice dam damage, call Wallenpaupack Roofers before the next freeze-thaw cycle worsens the situation. We serve Wayne, Pike, Monroe, and Lackawanna Counties for winter roofing emergencies.
What to Do Immediately After a Storm in NEPA
If you suspect your roof has sustained storm damage, follow these steps in order:
-
If you notice signs of storm damage on a roof, safety should always come first. Do not climb onto your roof after a storm, as wet or damaged roofing surfaces can be extremely dangerous. When checking for signs of storm damage on a roof, all inspections should be performed from the ground or by a licensed roofing professional.
Document any signs of storm damage on a roof from a safe distance. Take clear photos of missing shingles, damaged gutters, bent flashing, fallen debris, and any visible property damage. Proper documentation can be extremely helpful when filing an insurance claim.
Another important step is checking your attic for signs of storm damage on a roof. Look for water stains, wet insulation, mold growth, or daylight coming through the roof decking. These hidden warning signs often indicate damage that is not visible from the outside.
If you suspect signs of storm damage on a roof, contact a licensed roofing contractor as soon as possible. A professional inspection can identify both visible and hidden issues before they become more expensive repairs.
After confirming signs of storm damage on a roof, contact your homeowner’s insurance provider. Most insurance companies require photos, inspection reports, and written assessments from qualified roofing contractors. Wallenpaupack Roofers can provide the documentation needed to support your claim.
Does Homeowner’s Insurance Cover Storm Damage in Pennsylvania?
In most cases, yes — standard homeowner’s insurance policies in Pennsylvania cover roof damage caused by sudden storm events including hail, wind, falling trees, and lightning. However, policies do not cover damage resulting from gradual wear, lack of maintenance, or pre-existing conditions.
The key is acting quickly after a storm and getting a professional inspection to document the damage properly. Insurance adjusters will schedule their own inspection, and having an independent contractor’s assessment gives you a strong, informed position when the adjuster visits.
Wallenpaupack Roofers works with homeowners throughout Wayne, Pike, Monroe, and Lackawanna Counties to provide the documentation, photos, and written reports that insurance companies require. We do not charge for storm damage inspections — call us at (570) 390-3166 to schedule yours.
Frequently Asked Questions
How soon after a storm should I have my roof inspected?
As soon as safely possible — ideally within 24 to 48 hours of the storm passing. Many insurance policies have deadlines for reporting storm damage, and waiting too long can allow hidden damage to worsen significantly. Wallenpaupack Roofers offers prompt post-storm inspections across NEPA.
Can hail damage a roof even if the hailstones were small?
Yes. Even small hailstones — half an inch in diameter or less — can dislodge granules from asphalt shingles, crack thin roofing components, and damage rubber pipe boots. The damage may not cause an immediate leak, but it accelerates aging and creates vulnerability to future water intrusion.
What is the difference between wind damage and hail damage on a roof?
Wind damage typically causes lifted, curled, missing, or displaced shingles — often concentrated on one side of the roof facing the wind direction. Hail damage appears as circular impact points, granule loss, and denting on metal components, and is usually distributed across the entire roof surface rather than concentrated on one side.
Should I get on my roof to check for storm damage myself?
No. Walking on a storm-damaged roof is dangerous, and you risk both personal injury and additional damage to already-weakened roofing materials. A licensed roofing inspector has the training, equipment, and insurance to perform a safe and thorough storm damage assessment.
