Roof Storm Damage: How to Spot It and What to Do

Direct Answer

Question: How do I know if my roof has storm damage?

Roof storm damage signs include missing or displaced shingles, dented metal flashing, cracked or bruised shingles from hail impact, granule accumulation in gutters after a storm, and interior ceiling staining appearing within 24 to 48 hours of a major rain event. On metal roofing, look for dimpling across the surface. If your area experienced winds above 60 mph or hail above 1 inch in diameter, schedule a professional inspection even if no obvious damage is visible.

Why Storm Damage Matters More in Bucks County Than National Guides Suggest

Southeastern Pennsylvania is in one of the most active severe weather corridors in the northeastern United States. NOAA data for Bucks County and surrounding areas shows consistent spring and summer thunderstorm events, with hail events occurring multiple times annually and wind gusts from severe storms frequently reaching 60 to 80 mph or higher.

National guides to roof storm damage often underestimate both the frequency of weather events and the compounding effect of Pennsylvania’s freeze-thaw cycles on pre-existing storm damage. A small hail impact crack in a shingle that allows water beneath the surface in August becomes an ice dam entry point in February — exponentially escalating the damage.

Types of Roof Storm Damage and How to Identify Them

Wind Damage to Shingles

Question: What does wind damage to a roof look like?

Wind damage typically appears as lifted, creased, or missing shingles — particularly along ridge lines, eave edges, and any sections where shingles were nearing the end of their adhesive seal strip life. Even when shingles are not missing, wind-lifted shingles that have settled back down often have compromised seal strips that allow future water infiltration and further wind vulnerability.

Look for shingles with visible crease lines running diagonally across the face
Check ridge caps — these are often the first sections to dislodge in wind events
Inspect eave edges and rakes (roof edges at gable ends) where wind uplift is greatest
Examine flashings around chimneys and penetrations, which can be lifted and separated by wind pressure

Hail Damage to Asphalt Shingles

Question: How do I know if my roof has hail damage?

Hail damage to asphalt shingles produces circular bruise-like impact marks that remove granule coating from the shingle surface. These impacts compromise the shingle’s UV protection and allow moisture into the asphalt mat beneath. Small hail impacts (under 3/4 inch) may be cosmetic initially but accelerate aging significantly. Hail above 1 inch in diameter almost always causes functional damage that warrants insurance review.

Granule loss: Check gutters and downspout outlets for concentrated granule accumulation after hail events
Impact marks: Look for dark, round spots where granules have been dislodged — bare spots on shingles
Soft spots: Gently pressing on a hail-impacted area may reveal sponginess where the mat beneath has been fractured
Metal context: Check metal flashing, gutters, downspouts, and AC unit fins for denting — hail that dents soft metal causes functional asphalt shingle damage

Storm Damage to Metal Roofing

Metal roofing is significantly more resistant to storm damage than asphalt shingles but is not immune. Standing seam metal can suffer impact denting from large hail (1.5 inch or larger), and fasteners on exposed-fastener panel systems can loosen under wind pressure. Check seams and panel edges for any lifting or separation.

Flashing Failures from Storms

Flashings around chimneys, skylights, vents, and wall transitions are among the most storm-vulnerable components on any roof. High winds can lift or partially displace metal flashings, creating immediate water entry points. After any major storm, inspect all flashings visually from ground level or with binoculars for visible lifting, separation, or missing sections.

What to Do Immediately After Roof Storm Damage

Stay safe — do not attempt to access your roof during or immediately after a storm.
Document from ground level — photograph all visible damage from ground level or with a drone if available. Use your phone’s timestamp to create a record.
Check interior spaces — inspect your attic and all ceiling surfaces for signs of active water infiltration.
Call your homeowner’s insurance company — most policies require timely reporting of storm damage claims. Call within 24 to 48 hours of the event.
Request a professional roof inspection — an experienced contractor will document damage that is not visible from ground level and prepare the scope of repair for your insurance adjuster.
Apply temporary protection if needed — if active leaking is occurring, a licensed contractor can apply emergency tarping to prevent additional interior damage while the full repair is arranged.

Storm Damage Roof Inspection Checklist

Check all roof slopes from ground level using binoculars for visible shingle displacement
Inspect gutters for granule accumulation from hail impact
Check all metal elements (flashing, gutters, downspouts) for denting
Inspect attic immediately after storm for daylight, moisture, or active dripping
Check ceiling surfaces in all rooms for new staining or soft spots
Photograph all visible damage with timestamps before any repair work begins
Document weather event date, time, and type for insurance claim purposes
Contact your insurer within 24 to 48 hours and request an adjuster visit

Storm Damage Myth: If Nothing Is Leaking Right Now, Nothing Is Wrong

Question: Is roof storm damage always visible inside the home?

No. The most damaging roof storm impacts — particularly hail damage and wind-lifted shingles — often produce no interior water intrusion for months. The damage compromises the weatherproofing layer without immediately allowing water through. Interior leaks typically develop when subsequent rain events push water into the now-vulnerable shingle system. By then, claims may be more complex and some damage may be attributed to ‘wear and tear’ rather than the original storm event. Inspecting promptly after a storm protects your claim.

Will Homeowner’s Insurance Cover Roof Storm Damage in Pennsylvania?

Question: Does Pennsylvania homeowner’s insurance cover storm damage to roofs?

Most standard Pennsylvania homeowner’s insurance policies cover storm damage to roofs from hail, wind, and lightning as a covered peril. Coverage for damage from ice dams, flooding, and normal wear and tear is typically excluded. WG Siding and Roofing has extensive experience working with Pennsylvania insurance adjusters and can document storm damage in the format adjusters require to maximize covered claim approval.
