Storm season and your roof

Wind and hail can damage a roof without it being obvious from the street. If a storm has come through, here's what to do first:

  1. Stay off the roof. Look from the ground and from windows.
  2. Note missing or flipped shingles, dented gutters and debris.
  3. Check ceilings and the attic for fresh water stains.
  4. Take photos and write down the date of the storm.
  5. Book a storm damage roof inspection.

Storm history in O'Fallon, IL

O'Fallon has had more documented hail days than almost any other town we serve. These are the National Weather Service storm reports for O'Fallon and Shiloh since 2022.

Source: National Weather Service St. Louis local storm reports, 2022–2026. Hail sizes are preliminary spotter and media reports.

Four hail events of 1.75 inches in two years means a lot of O'Fallon roofs have been hit more than once. If your roof was repaired after one storm and then hit again, the newer damage is a new claim — the inspection separates the two.

Working with your insurance

If you plan to file a claim, we can inspect the roof and give you a written estimate of the repair work. We are not a public adjuster, and your insurer decides what is covered. Our insurance and storm damage roofing page explains the process.

When replacement is the better value

Repairs make sense on a roof with plenty of life left. Replacement starts to make more sense when the shingles are worn across the whole roof, when you've had several repairs in a short time, or when damage reaches the decking underneath. Our roof repair and roof replacement pages go into more detail.

Questions about roofing in O'Fallon

My O'Fallon roof was hit in March 2025 and again in April 2025. Is that one claim or two?

Two dates of loss, and it matters: each has its own deductible and claim window, and the April hail may have damaged repairs or shingles that survived March. We photograph and date the damage pattern on each slope so the adjuster can see what belongs to which storm.

The March 2025 hail was wind-driven. Why does that matter?

Wind-driven hail hits the sides of the house as hard as the roof. In O'Fallon we saw west-facing slopes, siding, window screens and gutters all damaged on the same homes. A proper inspection covers the whole exterior, not just the roof, so nothing is left off the claim.

Which parts of O'Fallon do you cover?

All of O'Fallon and Shiloh, including the newer subdivisions off Scott-Troy Road, Green Mount and the areas near Scott Air Force Base, plus Lebanon and Mascoutah.

Can you work with military families near Scott AFB?

Yes. We're used to coordinating around deployments and PCS moves, and we can coordinate inspection access and documentation with a property manager if you're away when the roof needs attention.
