Storm Damage Assessment: What You Need to Know

Storm damage is rarely one peril. A severe storm hits a property with wind, hail, and water — sometimes all three in the same event. The carrier acknowledges the roof and misses the interior. The adjuster documents the wind damage and omits the water intrusion. The estimate covers the shingles but not the underlayment, the drywall but not the insulation, the obvious but not the secondary.

A thorough storm damage assessment is how you make sure the estimate covers everything the storm actually damaged — not just what the adjuster saw in 30 minutes.

Common Types of Storm Damage

Storm damage falls into four categories, and a complete assessment covers all of them:

Wind Damage

High winds lift shingles, break seals, and tear off ridges and flashings. The damage is not always visible from the ground — wind-lifted shingles may look intact but have broken seal strips, leaving the roof vulnerable to the next storm. A proper wind damage assessment includes checking seal strips, checking for creased shingles, and documenting lifted flashing.

Hail Damage

Hail leaves bruising on shingles, dents on metal components, and impact marks on soft metals like vents and gutters. The damage is per-slope — the north-facing slope may show impacts while the south does not. A hail damage assessment documents impact marks per slope and elevation, not a blanket "hail damage" statement.

Water Intrusion

Wind-driven rain enters through compromised flashing, missing shingles, and damaged vents. The water travels into the attic, saturates insulation, and stains ceilings. Secondary damage — mold growth, structural saturation — can develop weeks after the storm if the water intrusion is not documented and addressed.

Impact Damage

Flying debris, fallen limbs, and displaced objects cause structural impact damage. This can range from broken windows to structural damage to exterior walls and framing.

Immediate Steps After Storm Damage

1. Ensure safety. Keep everyone away from downed power lines, unstable structures, and standing water near electrical systems.
2. Document everything. Take wide shots and close-ups. Photograph every room, every slope, every elevation. Video is valuable — walk through the property and narrate what you see.
3. Prevent further damage. Tarp compromised roof areas, board up broken windows, and extract standing water. Mitigation is your responsibility under most policies — the carrier will not pay for damage that worsened because you did not act.
4. Report the claim promptly. Most policies require prompt reporting. Delay can give the carrier a reason to reduce the settlement.
5. Get a professional assessment. Before the adjuster arrives, or after they leave with a thin estimate, get a thorough damage assessment from someone who knows what to look for.

Why the Adjuster's Assessment Is Often Incomplete

After a major storm, adjusters are overwhelmed. They may have 50 claims in queue. They spend 30 minutes on site, photograph the obvious damage, and move on. Secondary damage — the water in the wall cavity, the mold risk, the compromised underlayment — is the first thing to get missed.

This is not a criticism of adjusters. It is a function of volume. But it means the initial estimate almost always undervalues the claim. The storm damage estimate you submit as a supplement is what closes that gap.

What a Thorough Storm Damage Assessment Includes

A complete storm damage assessment covers:

• Roof inspection per slope — shingle condition, seal strips, hail bruising, missing and lifted materials
• Underlayment and decking — water staining, soft spots, compromised moisture barriers
• Flashing and penetrations — lifted flashing, damaged boots, compromised seals around vents and chimneys
• Interior inspection — ceiling stains, wet insulation, drywall damage, moisture readings
• Exterior inspection — siding damage, gutter dents, window damage, impact marks
• Secondary damage — mold risk, structural saturation, compromised air quality

Every item gets photo documentation. Every photo gets tied to a line item in the Xactimate scope. That is how you build a storm damage estimate the carrier has to take seriously.

Documenting Storm Damage for a Xactimate Estimate

The assessment feeds the estimate. When the scope is built in Xactimate, every line item is tied to the photo evidence from the assessment. Wind, hail, and water damage go into one connected scope — not separate estimates that let the carrier pick one peril and ignore the others.

This is the advantage of a single, multi-peril Xactimate scope: the carrier cannot acknowledge the wind and deny the water because they are in the same file, tied to the same photo documentation, with the same line-item structure.

Virtual vs. In-Person Storm Assessment

Not every storm claim needs a site visit. Virtual Xactimate estimates use aerial imagery, photos, and adjuster notes to build a complete storm scope without a site visit — typically delivered within 24 hours. For straightforward roof and interior damage, virtual scoping is fast and cost-effective.

In-person inspections provide hands-on documentation for complex claims. In Florida, in-person scoping is available statewide. Outside Florida, virtual estimating is the standard, with on-site inspections available for large-loss projects by arrangement.

The Bottom Line

Storm damage is multi-peril, and the initial estimate almost always misses something. A thorough assessment — documented per slope, per room, per line item — is how you make sure the estimate covers everything the storm actually damaged.
