Why Storm Intelligence Matters for Your Property

Storm data is actionable intelligence — but only if you know how to use it. Here is what HOA boards, property managers, and insurance adjusters need to know.

For HOA Boards

What to Do in the First 72 Hours After a Storm

A storm hitting your community is a clock-start event, not a wait-and-see situation. The first 72 hours set the foundation for your entire insurance claim. Here is the process that protects your community and your claim.

Hour 0–6: Walk all building exteriors immediately after the storm passes. Photograph every elevation, every soft metal surface (gutters, A/C units, cap flashing), and any visible shingle impact marks. Do not allow any cleanup or repairs yet — document first. Notify your insurance carrier to place them on notice. This is not filing a claim; it is preserving your right to file.

Hour 6–24: Contact a licensed commercial roofing contractor for an inspection appointment. An independent inspection report, dated within the storm window, is the single most important document in your claim file. The report should include NWS storm event correlation, hail size measurements (or wind speed), and photo documentation cross-referenced with the event data on this dashboard.

Hour 24–72: With inspection report in hand, formally file your claim. Request a commercial specialist adjuster — not a general property adjuster. Provide your inspection documentation package up front. This positions your board to negotiate from a factual baseline rather than waiting for the adjuster's unilateral assessment.

Can we authorize emergency tarping before the adjuster visits?

Yes — emergency mitigation is required to prevent further damage and is typically reimbursable. Document all temporary repairs with before/after photos and retain all receipts. Do not begin permanent repairs until the adjuster approves scope.

How long is our claim window after this storm?

Most commercial property policies allow 12–24 months from the storm date, but carriers require notice of loss within 30–60 days. Place notice immediately — the formal claim can follow once your documentation is complete.

For Property Managers

Property Manager Storm Response Checklist

Managing multiple buildings means a single storm event can create 10, 20, or 30 simultaneous inspection needs. A repeatable process — not improvisation — is what protects your properties and your relationships with ownership groups.

Immediately after the storm: Walk all building exteriors for safety hazards before you do anything else. Note any visible damage to roofing, gutters, siding, and signage. Photograph everything from multiple angles — wide establishing shots and close-ups of damaged areas.

Within 6 hours: Notify the property owner or HOA board. Activate your emergency vendor list — you should have a roofing contractor, restoration company, and public adjuster (if applicable) on retainer or on a preferred vendor list. Place your insurance carrier on notice. This is not filing a claim; it is preserving your claim rights.

Within 24 hours: Engage a licensed commercial roofing contractor for a formal inspection. The inspection report is the cornerstone of your claim. It should be dated within the storm window, include NWS event data, and document each affected building individually.

Within 72 hours: Submit a formal claim with your documentation package. A well-prepared submission with an inspection report, NWS corroboration, and photographs dramatically accelerates adjuster response and reduces the chance of a denial.

How does storm tracking data help my claim process?

NWS storm event data — the same data shown on this dashboard — is the official third-party source insurance adjusters use to verify that a storm occurred at a given location, date, and magnitude. Having this data cross-referenced in your inspection report eliminates one of the most common claim dispute points.

For Insurance Adjusters

Understanding Insurance Claim Windows for Storm Damage

Storm damage insurance claims are time-sensitive in ways most HOA boards and property managers underestimate. The clock starts at the storm event date — not when you discover the damage, and not when you call your contractor.

Notice of loss vs. formal claim: Most commercial policies require a formal "notice of loss" within 30–60 days of the storm event. This is a brief written notification that a storm occurred and your property was potentially affected — it does not require a completed inspection. Missing this window can void your claim entirely, even if the formal claim deadline is 24 months away.

How adjusters verify storm events: NWS and NOAA storm event records are the standard third-party corroboration source. Adjusters cross-reference your property coordinates against the documented storm track, hail size reports, and wind speed measurements. Properties within the documented storm track with physical damage consistent with the recorded magnitude are typically approved. Properties at the storm margin are where documentation quality makes the difference.

Damage thresholds by roof type: Asphalt shingles require ≥ 1.0 inch hail for most carrier approvals. Low-slope membranes (TPO, EPDM, modified bitumen) can document legitimate damage at smaller hail sizes, especially on aged systems. Wind claims typically require ≥ 60 mph documented wind speeds. This dashboard displays all NWS-recorded events with these parameters, enabling you to assess claim viability before inspection.

What is the minimum hail size for a commercial roofing claim?

Most carriers require ≥ 1.0 inch (quarter size) for asphalt shingle systems. Low-slope membrane systems may qualify at smaller sizes — an inspection report documenting actual damage is required regardless of hail size.

How far does a property need to be from the storm center to qualify?

NWS storm tracks are paths, not points. Properties within 10–15 miles of the documented storm path and showing physical damage consistent with the event magnitude are generally eligible. The storm data on this dashboard includes NWS source IDs that can be cross-referenced with official NOAA records.

Storm Intel & Hail Damage FAQ

What is Storm Intel?

Storm Intel is our real-time tracking system for severe weather events affecting HOA, condo, and multifamily properties across MN, WI, IA, ND, and SD. We integrate NOAA Storm Prediction Center outlooks, NWS hail reports, and on-the-ground inspection data into a city-level risk map that property managers and HOA boards can check anytime.

How does Storm Intel help with insurance claims?

Documented NOAA storm data at the property address is foundational evidence for a hail damage claim. Storm Intel maps active storm events to specific cities and ZIP codes so claim documentation includes verified date, time, hail size, and storm path data. This is what adjusters need to validate a claim.

What is a "predicted impact zone"?

A predicted impact zone is a geographic area where the NWS Storm Prediction Center has issued an elevated risk for hail or severe wind in the next 24–72 hours. We use these forecasts to pre-position inspection crews so we can deploy within 48–72 hours of a confirmed event.

Do I have to live in a storm zone to use Storm Intel?

No. Storm Intel is free to use for any HOA board, condo association, property manager, or homeowner curious about storm activity in their city. Bookmark it and check it after any severe weather event in your area.

What hail size causes roof damage?

Generally, hail 1.0 inch and above (quarter-size and larger) starts to cause measurable damage to asphalt shingle roofs. Hail 1.5 inch (ping-pong ball size) reliably damages most residential and commercial roof systems. Hail 2.0 inch (egg-size) and above causes severe damage requiring full replacement. We document hail size with on-site measurement.
