After a severe storm -- whether wind, hail, rain, or a combination -- your roof may have sustained damage that is not immediately obvious from inside the house. A prompt and systematic assessment within '''24 to 48 hours''' of the storm protects your home from secondary water damage and strengthens your position if you need to file an insurance claim.

{{Warning|'''Safety comes first.''' Do not attempt any roof assessment until the storm has fully passed and conditions are safe. Watch for downed power lines, unstable trees, standing water, and lingering high winds. Never go on a wet roof. Review the [[Roof Safety Guide for Homeowners]] before accessing any elevated area.}}

== Timing Matters ==

Assess your roof within '''24 to 48 hours''' of the storm for several reasons:

* '''Prevent secondary damage''' -- a small puncture or displaced shingle can allow water intrusion during the next rainfall, turning a minor repair into a major one
* '''Preserve evidence''' -- hail dents, displaced shingles, and debris tell the storm's story. Rain, wind, and sun can obscure damage within days
* '''Insurance deadlines''' -- most homeowner's policies require notice of damage within '''30 to 60 days'''. Early documentation is far more persuasive than a claim filed months later. See [[How to Document Roof Damage for Insurance]] and [[Roofing Insurance Claims and Warranties]]
* '''Contractor availability''' -- after major storms, roofing contractors are overwhelmed with calls. Early assessment gets you in the queue sooner

== Safety Precautions ==

* '''Wait for the storm to fully clear''' -- no lightning, sustained winds under 15 mph, no active precipitation
* '''Watch for downed power lines''' -- do not approach any wire on the ground or draped over your home. Call your utility company immediately.
* '''Do not go on a wet roof''' -- wet shingles are extremely slippery. Wait until the surface has dried.
* '''Beware of weakened structures''' -- if the roof appears to sag, a tree has penetrated the structure, or you suspect structural damage, do not enter the attic or go on the roof. Call a structural professional.
* '''Wear appropriate footwear''' -- if you do go on the roof, wear rubber-soled shoes with good traction

== Ground-Level Exterior Inspection ==

Begin your assessment from the ground. Many types of storm damage are visible without climbing a ladder.

=== Walk the Perimeter ===

Walk completely around your home and look for:

* '''Shingle debris on the ground''' -- shingle tabs, granule piles, or entire shingles blown off the roof are obvious signs of wind damage
* '''Visible damage from the ground''' -- use binoculars to scan the roof surface. Look for bare patches, lifted tabs, and displaced flashing
* '''Dented or detached gutters''' -- hail and wind stress gutters and their mounting hardware. Dented gutters are one of the '''easiest indicators of hail damage''' and suggest the roof surface likely sustained similar impacts. See [[Roof Drainage]] for gutter system information.
* '''Downed tree limbs on or near the roof''' -- even if a limb did not penetrate the roof, its impact may have cracked shingles, dislodged flashing, or dented metal components beneath it
* '''Siding and window damage''' -- damage to vertical surfaces strongly suggests the roof sustained damage as well, since the roof is more exposed than walls

=== Check Metal Components First ===

Metal surfaces show hail damage more clearly than shingles. Check these for dents:

* '''Roof vents and exhaust caps''' -- aluminum and galvanized vents dent easily and provide clear evidence of hail impact size
* '''Gutter troughs and downspouts''' -- run your hand along the surfaces feeling for dents
* '''Flashing''' at chimneys, walls, and valleys
* '''HVAC condensing units''' -- outdoor AC units often sit near the house and show hail dents on their fins and housings
* '''Metal fences, mailboxes, and vehicles''' -- damage to these ground-level items confirms the storm's severity and helps establish the storm's damage footprint for insurance purposes

== Attic Inspection ==

Before going on the roof, check the attic for signs of water intrusion.

* '''Look for new water stains''' on the underside of the roof sheathing and on rafters. Active dripping is an obvious sign, but even damp patches indicate a breach.
* '''Check for daylight''' coming through the roof deck -- any new pinpoints of light indicate holes from debris impact or lost shingles
* '''Feel the insulation''' for moisture -- wet insulation directly below a roof penetration or in a specific area points to the breach location. See [[Roof Insulation]] for information on insulation performance.
* '''Note any musty or unusual odors''' that were not present before the storm

If you find active water intrusion, take immediate steps to protect your interior. See [[Emergency Roof Repair What to Do Right Now]] for triage actions.

== Roof-Surface Inspection ==
[[File:tree-limb-damage-on-roof.jpg|thumb|right|Large tree limb fallen onto a residential roof causing visible structural damage to shingles and decking]]

If the roof is dry and you can safely access it (or observe with binoculars from a ladder at the eave), look for these specific types of storm damage. See [[How to Inspect Your Roof]] for general inspection technique.

=== Wind Damage ===

Wind damage has characteristic patterns:

* '''Creased or folded shingles''' -- wind lifts a shingle tab and bends it backward, breaking the sealant bond and creating a permanent crease
* '''Missing tabs or entire shingles''' -- high winds rip shingles free, especially at roof edges, ridges, and hips where wind speed accelerates
* '''Lifted shingle edges''' -- tabs that have lost their sealant bond stand up at the leading edge, vulnerable to the next storm
* '''Damaged ridge caps''' -- ridge cap shingles are the most wind-exposed components on the roof. See [[How to Install Ridge Cap Shingles]] for replacement guidance.
* '''Directional pattern''' -- wind damage typically affects one slope more than others, corresponding to the storm's wind direction

=== Hail Damage ===

Hail damage can be subtle on asphalt shingles. Look for:

* '''Random circular dents''' in the shingle surface -- hail impacts displace granules and create soft spots in the shingle mat
* '''Exposed fiberglass mat''' -- where the impact was severe enough to knock away the surface granules and expose the underlying mat material. This appears as dark or shiny spots.
* '''Cracked shingles''' -- large hailstones (1 inch diameter or larger) can crack the shingle mat beneath the granule surface, often creating fracture lines that radiate from the impact point
* '''Dented flashing and vents''' -- as noted above, metal components show hail more clearly than shingles. Dented vents with similar-sized dents confirm hail size.

On [[Metal Roofing]], hail creates visible dents in panels. On [[Tile Roofing]], hail cracks or chips tiles. On [[Slate Roofing]], hail can crack or break individual slates. See [[Hail Damage and Roofing]] and [[Signs of Roof Damage After a Storm]] for more detail.

=== Debris Impact Damage ===

* '''Punctures''' from fallen branches or airborne debris -- these require immediate temporary patching. See [[How to Apply Emergency Roof Tarp]].
* '''Broken tiles or slates''' from fallen limbs
* '''Displaced or crushed ridge vent''' material
* '''Torn or displaced flashing''' at chimneys, walls, or penetrations

== Documentation ==

Thorough documentation is essential for insurance claims and contractor communication. See [[How to Document Roof Damage for Insurance]] for a complete documentation guide.

At minimum, during your assessment:

* '''Photograph all damage''' -- take both wide-angle shots showing context and close-up shots showing detail
* '''Include a scale reference''' in close-up photos -- a coin, ruler, or your hand next to damage helps adjusters gauge severity
* '''Photograph undamaged areas''' for comparison -- this helps distinguish storm damage from normal wear
* '''Take video''' -- a narrated walkthrough with verbal descriptions supplements photos and provides context that still images cannot
* '''Note the date and time''' of your assessment -- email photos to yourself for a timestamped digital record
* '''Save weather reports''' from the storm date -- these are available from the National Weather Service and establish the type and severity of the event

== Immediate Action Items ==

After completing your assessment, take these steps in order:

# '''Address active leaks''' -- if water is entering the home, take immediate interior protection steps. See [[Emergency Roof Repair What to Do Right Now]].
# '''Apply temporary protection''' -- if you can safely access the roof and there are exposed areas, apply a temporary tarp. See [[How to Apply Emergency Roof Tarp]].
# '''Contact your insurance company''' -- report the damage and begin the claims process. See [[Roofing Insurance Claims and Warranties]] for guidance on working with your insurer.
# '''Get contractor estimates''' -- obtain estimates from at least three licensed roofing contractors. Be cautious of storm chasers (out-of-area companies that follow storms). See [[When to DIY vs When to Call a Roofer]] for guidance on choosing a contractor.
# '''Do not make permanent repairs''' until the insurance adjuster has inspected the damage, unless emergency repairs are needed to prevent further water intrusion. Insurance companies expect to see the damage before authorizing repairs.

== Common Mistakes After a Storm ==

* '''Waiting too long to inspect''' -- secondary water damage from an undetected breach can cost far more than the original storm damage
* '''Going on the roof too soon''' -- wet shingles, weakened structures, and downed power lines are all post-storm hazards
* '''Failing to document''' -- without photos and records, insurance claims are harder to settle and contractor estimates are less accurate
* '''Signing a contract with the first storm chaser who knocks''' -- take time to vet contractors. Legitimate companies do not pressure you to sign immediately.
* '''Making permanent repairs before the adjuster visits''' -- the adjuster needs to see the damage to approve coverage
* '''Ignoring interior damage''' -- water stains on ceilings and walls may not appear for days after the storm. Monitor interior spaces for weeks following significant events.
