A storm moves through the NH Seacoast, and an hour later the sky is clear. Your yard looks fine. Your windows are intact. But your roof absorbed the same storm, and unlike your car or your siding, it doesn't always show obvious damage right away.
This is the problem with hail and wind damage on residential roofs. The signs that matter most to your insurance company and your roof's long-term performance are often the ones you can't see from the driveway. A roof that looks completely fine from the ground can have cracked shingles, broken adhesive seals, dented flashing, and granule loss that will shorten its lifespan significantly. That damage needs to be documented within your policy's claim window, not discovered six months later when a ceiling stain appears.
This guide covers exactly what hail and wind damage look like on NH Seacoast roofs, how to conduct a safe ground-level inspection yourself, and when to call a professional before the damage gets worse or the claim window closes.
Why NH Seacoast Storms Cause Different Damage Than Inland Areas
Before getting into the specific damage signs, it's worth understanding why coastal NH homeowners face a slightly different inspection challenge than their inland neighbors.
Wind-driven rain and hail hit differently on exposed coastal properties in Hampton, Hampton Beach, Seabrook, and Rye than on a sheltered inland home. On a coastal property, the windward side of your roof takes the brunt of nor'easters and summer storm systems, while the opposite slope may show little or no damage at all. This uneven loading pattern means that a quick visual check of the most visible slope from the street can give you a false sense that the roof is fine.
Salt air is the other factor that makes coastal NH different. It accelerates corrosion of damaged metal flashing and exposed fasteners far faster than inland conditions. A small hail impact that dents a pipe boot flashing or vent cap in Hampton Beach can turn into a rust and leak problem much faster than the same damage would cause in Exeter or Dover. That's why inspecting after every significant storm matters more on the Seacoast than it might elsewhere.
Step 1: Start on the Ground Before You Look at the Roof
The safest and most informative first step is a systematic walk around your entire property, not just a glance at the roof from your driveway. You are looking for collateral damage that confirms what may have happened on the roof.
Check your gutters and downspouts first. Aluminum gutters are one of the most reliable indicators of hail severity. Hail that is large enough to damage shingles almost always dents aluminum gutters visibly. Run your hand along the gutter face and look for round impact dents of consistent size. At the same time, look inside the gutters. A significant accumulation of dark granules after a storm means the shingles above lost their protective coating on impact.
Check soft metal surfaces around the house. AC condenser fins, aluminum window screens, roof vent caps, and soffit panels all dent more easily than shingles and show hail impact clearly. If your condenser fins show multiple impact dents, treat that as strong evidence that your roof took meaningful hits. If you see dents on a car that was parked outside during the storm, your roof almost certainly has damage too.
Look for debris and shingle pieces in the yard. Whole shingles or shingle fragments in your yard or against your foundation are an obvious wind damage indicator. Less obvious but worth checking: small pieces of shingle tab, corners, or granule piles concentrated near downspout exits.
Check window screens and siding. Hail tears small holes in window screens and leaves circular impact marks on vinyl or aluminum siding. These are easy to see from ground level and help establish that hail was large enough and dense enough to have caused functional roof damage.
Step 2: Roof Inspection From the Ground
Never climb onto a storm-damaged roof yourself. A wet, debris-covered, or structurally compromised roof is genuinely dangerous, and most storm damage can be identified from the ground using binoculars or a camera zoomed in from a safe vantage point.
Walk the perimeter of your home and inspect each roof slope from multiple angles. Here is what to look for on each component.
Shingles: What Hail Damage Looks Like
Hail damage on asphalt shingles has a specific appearance that is different from normal wear. You are looking for a few key things.
Random circular impact marks are the most telling sign. Hail strikes in random patterns across the shingle surface, unlike normal wear which is uniform across the whole roof. The marks may look like small dark spots or areas where the shingle surface has a different texture from the surrounding material.
Granule loss concentrated at impact points is another clear indicator. The protective granule layer gets knocked loose by hail, exposing the darker asphalt mat underneath. From a distance this looks like darker patches or spots scattered across the shingle rather than a uniform pattern.
Cracked or split shingles occur when larger hail hits directly. Look for visible fracture lines, especially near shingle edges, which tend to be more vulnerable than the center of the shingle.
Soft spots or bruising are less visible from the ground but worth mentioning because a professional inspector will press on shingle surfaces to check for soft areas where the underlying mat has been damaged without an obvious surface crack. If your inspector finds these, it typically means the shingle is compromised even if it looks fine visually.
Shingles: What Wind Damage Looks Like
Wind damage looks distinctly different from hail, and understanding the difference matters for how you describe the damage to your insurer.
Missing shingles are the most obvious sign. Look for visible gaps or bare decking areas, most commonly at roof corners, along rake edges at the gable ends, and along the ridge line where wind uplift is highest.
Lifted or curling shingle edges are trickier to catch. Shingles that have been partially lifted by wind may settle back down and look normal from a distance, but their adhesive seal is broken. The next storm finishes the job. Look for edges that sit slightly higher than surrounding shingles or that show a visible gap underneath.
Creased shingles with a horizontal fold line across the tab are a wind-specific damage signature. This happens when wind lifts a shingle and then slams it back down, creating a visible crease. Once you know what to look for, these are fairly easy to spot from ground level with binoculars.
Directional pattern is also telling. Unlike hail's random distribution across all slopes, wind damage tends to concentrate on the windward side of the roof and along exposed perimeter edges.
Flashing: Check Every Transition Point
Flashing failures are the most common single source of post-storm interior leaks, and they are frequently missed because the damage is subtle. Wind can pull counter-flashing away from chimney faces by just a few millimeters. That gap is invisible from the street but enough to let water in during the next rain. Hail can dent the rubber boot seals around plumbing vent pipes, cracking them open at the base.
From the ground, pay particular attention to the flashing where your chimney meets the roof, looking for any visible gaps, lifted metal, or separated sections. Also check the pipe boot flashings around plumbing vents and the valley flashing along roof valleys where two slopes meet.
If you have had flashing issues before or want to understand what failing flashing looks like in more detail, our chimney flashing repair guide explains the specific signs and why flashing leaks are often mistaken for shingle problems.
Gutters and Fascia
Beyond the hail dent check in Step 1, look for gutters pulling away from the fascia board, which is a sign of ice or debris load damage. Also check for fascia boards with water staining or soft spots, which indicates water has been getting behind the gutter for some time. Downspouts that have separated at joints or pulled away from the wall are also worth noting and photographing.
Step 3: Check Inside Your Home
After completing your exterior walk, go inside and walk through every room with the lights on and look up. Interior signs of roof damage include new ceiling stains that were not there before the storm, paint bubbling or peeling near the roofline or on walls adjacent to exterior walls on upper floors, and musty odors in the attic.
If you can safely access your attic, check for damp insulation, wet decking, or daylight visible through the roof boards. Wet attic insulation loses its insulating value immediately and can develop mold quickly if not addressed, so this step is worth doing even if you see no interior staining.
Document any interior findings with date-stamped photos before you dry anything out. These photos matter for your insurance claim and help establish that the damage was connected to a specific storm event.
Hail vs. Wind: Why the Difference Matters for Your Claim
Insurance adjusters treat hail and wind damage differently, and knowing which you are dealing with helps you describe the damage accurately from the start.
Hail damage is the more disputed category. It is often harder to see clearly, its severity depends on hailstone size and density, and some insurers push back on the idea that small hail causes functional rather than cosmetic damage. The key distinction is whether the hail compromised the shingle's ability to shed water. Granule loss, cracked mats, and dented flashings are functional damage. Surface marks that do not affect waterproofing are cosmetic. A professional inspection documents exactly which category applies.
Wind damage is generally more straightforward to document since missing shingles, lifted edges, and creased shingles are visible and clearly functional. The challenge with wind damage is catching the lifted-but-resettled shingles whose broken adhesive seals are not obvious until they blow off in the next storm.
For both types, prompt professional inspection and documentation is more useful than waiting to see if a leak develops. By the time interior damage is visible, the exterior damage has already been there long enough to complicate your claim and your repair scope. For a full walkthrough of the insurance claim process after storm damage, our storm roof damage insurance claim guide covers what to document, how to work with your adjuster, and what to do if a claim comes back underpaid.
When to Call a Professional Immediately
Call a roofing contractor for a professional inspection if you see dents on your gutters, AC unit, or car from the same storm, if you find shingle pieces or granule accumulations in your yard, or if you notice any new ceiling stains or interior moisture after the storm. You should also call if the storm included hail larger than quarter-size, if sustained winds exceeded 50 to 60 mph, or if your roof is more than 15 years old. Older shingles are more vulnerable to damage that does not look dramatic from the ground but meaningfully shortens remaining lifespan.
If there is an active leak or visible hole, do not wait. Our emergency roof repair service operates 24/7 across the NH Seacoast and can stabilize the damage before the next rain event.
Frequently Asked Questions
Can I inspect my own roof after a storm?
From the ground, yes, and this guide covers exactly how to do that safely. Never climb onto a damaged roof yourself. Wet, debris-covered, or structurally compromised roofs are genuinely dangerous, and most storm damage is identifiable from safe ground-level vantage points with binoculars or a zoom camera.
How quickly do I need to report storm damage to my insurer?
As soon as possible after discovery. Most policies have reporting requirements within a specific number of days of the storm event. Do not wait to see if a leak develops. Report the damage and schedule an inspection while it is fresh and your claim window is open.
What if the storm happened weeks ago and I did not check right away?
Document the damage now with date-stamped photos and note the storm date as accurately as you can. Weather records and local news coverage of specific storm events can help corroborate the timing. Call your insurer and schedule a professional inspection. Some policies allow up to a year from the storm date, though waiting that long is never recommended.
Does quarter-sized hail really damage roofs?
Yes. Quarter-sized hail, about one inch in diameter, is generally large enough to cause functional damage to standard asphalt shingles, including granule loss and mat cracking. On coastal NH homes where salt air accelerates deterioration of compromised areas, even smaller hail damage is worth a professional look.
What is the difference between cosmetic and functional hail damage?
Cosmetic damage refers to surface marks that do not affect the shingle's ability to shed water and may not be covered by all policies. Functional damage includes granule loss exposing the asphalt mat, cracks in the mat, and dented flashing. It compromises waterproofing and is what insurance claims are built around. A professional inspection distinguishes clearly between the two and documents the findings in a format your insurer can work with.
