Surviving St. Louis Hail Season: A Roof Guide for Homeowners

The peak window for severe thunderstorms and hail in the St. Louis region runs roughly from spring into early summer, when cold and warm air masses collide most often over the Midwest. The National Weather Service and NOAA's Storm Prediction Center track and report severe-weather events for the region, and their records are the authoritative source if you want to confirm that a hail event hit your specific area on a specific date — which matters a great deal if you later file an insurance claim.

Hail can fall outside that window too; Missouri storms don't read calendars. But spring through early summer is when you should be most alert, and when it's worth a quick roof and gutter check after any storm that sounded like it was throwing gravel at the windows.

Hail damage is often not the dramatic, obvious thing homeowners expect. Large hail can crack or puncture shingles outright, but a lot of damaging hail leaves bruises: spots where the impact knocked the protective granules off the asphalt and softened the mat underneath. From the ground these are nearly invisible. Up close they look like dark, pockmarked circles where the surface granules are gone.

That granule loss is the real problem. The granules are the shingle's sunscreen and armor; once they're knocked off, the exposed asphalt degrades faster under UV and weather, and the bruised spot becomes a future leak. This is why hail damage can be "functional" — meaning it shortens the roof's life — even when the roof still looks fine and isn't leaking yet. It's also why an honest inspection matters more than a glance.

The single most important rule: stay off the roof. A wet or hail-scattered roof is genuinely dangerous, and you can do every useful check from the ground or a ladder you're comfortable on. The goal of your inspection is not to grade the roof — it's to decide whether you need a professional to.

Walk the perimeter of the house. Check the soft metal first because it's the easiest read: dented gutters, downspouts, window screens, and especially the fins on your outdoor AC unit. Look at the ground for shingle granules and any pieces of shingle. Inside, check ceilings and the attic (if accessible) for any sign of water intrusion — though leaks can take time to show, so a dry ceiling today doesn't mean you're clear.

If you suspect real damage, your phone is your most valuable tool before any roofer or adjuster gets involved. Photograph the date and the damage: the dented metal, the granule loss, anything on the ground. Note the date and rough time of the storm. This record is what supports an honest insurance claim later, and it protects you if a contractor or adjuster ever disputes when or how the damage occurred.

Resist the urge to sign anything on the spot. After major hail, neighborhoods fill with door-knockers — some legitimate, some not. A reputable roofer will inspect, document, and give you a written assessment without pressuring you to sign a contract before you've even confirmed a claim. Our storm-damage insurance guide walks through how the claim process actually works so you go in informed.

Once you've documented and decided you want a professional inspection, the question is who. After a big storm, the worst outcome is handing your number to every contractor who knocks and spending the next week fielding calls. The best outcome is one licensed, insured local roofer who shows up, inspects honestly, and tells you whether you have a claim-worthy loss or a roof that took the hit and held.

That's exactly what Routed is built to do. Tell us your roof took hail, and we match you with a single verified local pro for your area who calls you back — usually within a minute. Before we route anyone, we confirm their license and insurance (here's how we verify). One homeowner, one pro, nobody else gets your number. If you're deciding between patching the hail damage and replacing the roof, our repair-vs-replace guide is the right next read.
