The Metro East Illinois communities – Belleville, Collinsville, Edwardsville, O'Fallon, Granite City, Fairview Heights, and their neighbors – face the same severe weather threats as the rest of the greater St. Louis metropolitan area. Storms don't stop at the Mississippi River, and neither should your preparation.
This guide covers everything Metro East homeowners need to know about storm damage: how to identify it, what to do after a storm, how the insurance process works in Illinois, and how to protect yourself from common pitfalls.
The Metro East's Unique Storm Position
The Metro East sits on the eastern edge of one of the country's most active severe weather corridors. Storms building over the Plains states track eastward through Missouri and cross into Illinois with regularity during spring and early summer.
What makes the Metro East's position unique is that homeowners on the Illinois side often have a brief warning window after storms hit the Missouri side of the metro. Weather radar and local news coverage of damage in St. Louis County or north county can signal that hail is heading east across the river.
However, this brief warning doesn't change the outcome – if a storm is producing hail on the Missouri side, it will likely produce hail on the Illinois side. The value of the warning is in preparation: securing loose outdoor items, moving vehicles to covered areas if available, and being ready to document damage afterward.
Identifying Storm Damage on Your Property
After a hail event, check these areas for visible damage from ground level:
Gutters and downspouts: Look for dents, dings, and displaced granules. Granules accumulating at downspout exits are a strong indicator of roof damage above.
Siding: Hail creates circular impact marks on vinyl, aluminum, and fiber cement siding. These may appear as cracks, chips, or dents depending on the material.
Windows and screens: Check for cracked glass, torn screens, and dented window frames. Impact marks on window frames often correlate with the direction and intensity of hail.
Outdoor equipment: AC condensers, mailboxes, grills, and outdoor furniture all show hail damage more visibly than roofing materials. Damage to these items strongly suggests your roof was also impacted.
Do not climb on your roof. The most consequential hail damage – granule loss, shingle bruising, and mat cracking – requires professional assessment and is invisible from the ground.
How Insurance Claims Work in Illinois
Illinois insurance claim procedures differ from Missouri in several important ways:
Filing timeline: Most Illinois policies require claims within one year of the date of loss. File promptly – waiting weakens your claim.
Adjuster timeline: Illinois law requires insurers to acknowledge claims within 15 business days. The actual adjustment inspection typically occurs within 1–3 weeks depending on demand.
Contractor rights: You can choose any IDFPR-registered contractor. Your insurer cannot force you to use a preferred vendor.
Deductible rules: Your deductible is your responsibility. Any contractor who offers to waive or pay your deductible is violating Illinois law – and likely cutting corners on the work.

Why a Pre-Adjuster Inspection Matters
The insurance adjuster's visit is the single most important moment in the claims process. Their report determines your payout. Having a professional inspection before the adjuster arrives gives you two advantages.
First, you enter the adjuster visit with documented evidence of every area of damage. A comprehensive Roof Report Card with photos, measurements, and a clear damage summary gives the adjuster a roadmap of what needs to be examined.
Second, having a qualified representative present during the adjuster's visit ensures thoroughness. Adjusters handle dozens of claims during busy storm seasons. Having someone present who knows where the damage is and can point it out reduces the chance that legitimate damage is overlooked.
SDAT provides both: a free pre-adjuster inspection with a detailed Roof Report Card, and a team member present during the adjuster's visit to advocate for your roof.
Choosing a Contractor in Metro East Illinois
After a major storm, contractors from across the country descend on affected areas. While many are legitimate, the surge creates an environment where unqualified and unregistered operators can take advantage of homeowners.
Protect yourself by verifying Illinois IDFPR registration for any contractor you consider. Check for industry certifications like Haag Engineering Certification. Confirm that they carry the required liability and workers' compensation insurance.
Prioritize contractors with an established presence in the Metro East or greater St. Louis area. A company that has operated locally for years has a track record you can verify and a reputation to protect. They will also be available for warranty service long after the storm chasers have moved on.
SDAT has served the St. Louis metropolitan area since 1999 and now provides the same trusted service to Metro East Illinois homeowners.
After the Repair: Protecting Your Investment
Once your roof is repaired or replaced, take steps to protect your investment going forward.
Keep all documentation: your Roof Report Card, the insurance adjuster's report, the contractor's scope of work, warranty certificates, and material specifications. Store these digitally and in hard copy.
Understand your warranty: most Owens Corning shingle installations include both a manufacturer material warranty and a contractor workmanship warranty. Know what's covered, for how long, and how to file a warranty claim if needed.
Schedule periodic inspections: even without visible storm damage, having your roof inspected every few years establishes an ongoing record of its condition. This documentation is valuable if you sell your home or if future storms cause damage.
