Cracked and punctured siding lets moisture reach sheathing and framing — document it and fix it right before hidden rot and mold take hold
When a hailstone cracks a vinyl panel or punches through a lap joint, the damage you can see is only part of the problem. The greater danger is what happens next — and it happens fast. Cracked and punctured siding panels allow wind-driven rain and dew to wick behind the wall cladding, reaching the housewrap, sheathing, and framing beneath. In Lombard's humid continental climate, where summer humidity regularly exceeds 70% and freeze-thaw cycles assault structures from October through April, moisture that penetrates the wall assembly has nowhere to escape. Rot develops silently inside the wall cavity, eating away at OSB sheathing and wood framing while mold colonies establish themselves in the dark, damp space between panels and substrate. By the time any of this becomes visible from inside your home — as water stains, soft drywall, or musty odors — the remediation cost has multiplied far beyond what a timely siding repair would have cost.
Beyond the structural and health risks, there are critical insurance and logistical reasons to act quickly. Most homeowner's policies require prompt reporting of storm losses, and insurance carriers can deny claims or reduce settlements when they determine that preventable secondary damage occurred due to homeowner delay. Additionally, when specific siding profiles get discontinued by manufacturers — which happens regularly as product lines evolve — the window for an exact color-and-profile match closes over time, forcing homeowners into more expensive whole-elevation or full-replacement solutions that might have been avoided with earlier action. Every day of delay also means one more day of energy loss through a compromised building envelope, with conditioned air escaping through gaps that were never there before the storm.

Lombard is a mature DuPage County suburb of approximately 44,000 residents, situated along the historic Lincoln Highway corridor between Elmhurst to the east and Glen Ellyn to the west. The community is defined by its dense residential neighborhoods, many of which date from the 1950s through 1980s housing booms that left a legacy of vinyl and aluminum-sided homes that are now aging into their second and third decades. Neighborhoods like Westmore-Meyers on the village's southwest side, the Hammerschmidt area near the eponymous elementary school, and the Prairie Path Estates neighborhood to the northwest are full of single-family homes whose siding is both their primary weather defense and their most visible curb appeal asset. When a Midwest hailstorm sweeps through DuPage County, it's these neighborhoods — block after block of closely-spaced homes — that take the hit simultaneously.
Lombard is perhaps best known statewide for Lilacia Park, the stunning municipal garden near downtown that draws tens of thousands of visitors each spring during the Lilac Festival. The village's downtown area along St. Charles Road and Main Street features a mix of historic commercial buildings and residential bungalows that often present siding challenges unique to older construction — narrower panel profiles, wood-to-vinyl transitions, and decades of paint layers that complicate matching. The Illinois Prairie Path, a 61-mile multi-use trail that cuts through Lombard along an old railroad corridor, is flanked by residential backyards on both sides, and the open linear exposure means homes along the path corridor often experience elevated wind damage during straight-line wind events that accelerate through the unobstructed trail zone.
Geographically, Lombard sits on the flat glacial till plain that characterizes much of northeastern Illinois, with no significant topographic features to deflect or dissipate incoming storm cells. This means that when the National Weather Service issues a severe thunderstorm warning for DuPage County, Lombard receives the full energy of the storm system without the mitigation of hills, ridges, or tree canopy density. The village's mature street trees — particularly along the older residential grid streets like Elizabeth and Stewart — provide some wind buffering, but falling branches from those same trees are a recurring source of siding puncture and soffit damage during high-wind events. Allied Emergency Services understands Lombard's specific building stock, its storm exposure patterns, and its building department requirements, and we bring that local knowledge to every inspection we conduct in the village.
Every siding project in Lombard begins with a free inspection and ends with a written quality check. Here's what we do between those two steps.
When hailstones impact vinyl siding, they create circular impact craters, spiderweb cracks, and in severe cases, full punctures that breach the panel entirely. Wind events tear panels from their interlocking channels, expose housewrap, and drive rain directly into the wall assembly. Our storm repair crews are trained specifically in storm-pattern damage assessment — we don't just look at the obvious hits, we evaluate the entire perimeter of your home to ensure nothing is missed before we write a scope of work.
When damage is extensive, siding is aged beyond its useful life, or an insurance scope supports full replacement, Allied performs complete re-siding projects from tear-off to final trim installation. We remove old siding and inspect the sheathing beneath before a single new panel goes up — because installing premium new siding over compromised sheathing is a recipe for expensive problems down the road. We also install or upgrade the housewrap weather barrier during full replacements, improving the building envelope's long-term performance.
For Lombard homeowners whose siding sustained limited damage — a single elevation, a handful of panels on a corner, or isolated impact zones — a well-executed partial repair with precisely matched panels is often the smartest economic choice. The challenge is getting the match right. Siding colors fade over years of UV exposure, and panel profiles evolve or get discontinued. Our experienced estimators bring physical sample books to your home and evaluate both profile geometry and color in natural light so the match looks right after installation — not just in the warehouse.
Insurance claims for siding damage live or die on documentation quality. Adjusters work from photographs, measurements, and scope descriptions — and when that documentation is incomplete or poorly organized, claim outcomes suffer. Allied's inspection team documents siding damage the way experienced restoration professionals do: elevation-by-elevation photographs with consistent naming conventions, impact density counts per square, soft-metal corroborating evidence, and written scope descriptions aligned with Xactimate line items. We provide you with a complete copy of our documentation package to support your insurance claim process.
DuPage County sits in one of the most active severe weather corridors in the continental United States. Understanding Lombard's storm exposure helps homeowners know what to watch for and when to call for an inspection.
Lombard's most dangerous hail events typically arrive during the spring convective season, when cold Canadian air masses clash with warm Gulf moisture streaming northward over Illinois. March through May sees the highest frequency of organized severe thunderstorm outbreaks in the region. Supercell thunderstorms tracking northeast across DuPage County during this window can produce hailstones ranging from pea-sized (half-inch) to golf ball-sized (1.75 inches) and larger, with larger stones capable of destroying vinyl siding on impact and cracking fiber cement panels. Homeowners who experience spring storms should inspect their siding — or have Allied inspect it — before the next winter season to prevent moisture infiltration during the freeze-thaw cycle that follows.
Peak summer months bring isolated supercells and organized squall lines capable of producing damaging hail and straight-line winds exceeding 60 to 80 miles per hour. Lombard's flat terrain and lack of significant windbreaks means straight-line wind events from the west and southwest move through the village at full speed, lifting siding panels, tearing corner trim, and depositing debris against home exteriors. The DuPage County area has experienced multiple documented severe hail events during summer months, with hail accumulation on the ground — a phenomenon where hailstones pile up like snow — causing particularly widespread damage across entire residential neighborhoods simultaneously. Insurance claim volumes in DuPage County typically spike dramatically in the weeks following major summer storm events.
As storm tracks shift southward in fall, Lombard experiences fewer hail events but remains vulnerable to high-wind episodes associated with strong cold fronts and post-frontal pressure gradients. Wind speeds during fall frontal passages regularly reach 40 to 55 mph, sufficient to lift poorly-nailed or aged siding panels, strip caulking from trim joints, and tear soffit panels from their channels. Homeowners with older siding installations — particularly those where original nails have corroded or backing strips have degraded — are most vulnerable to fall wind damage. A fall inspection after any significant wind event is a practical investment before winter moisture exposure begins.
While Lombard doesn't typically receive major hail in winter, the freeze-thaw cycle from December through February is a critical damage amplifier for siding that was compromised during the previous storm season. Water that infiltrated behind cracked panels during summer storms freezes and expands in winter, widening cracks, lifting panel edges further from their channels, and accelerating rot in the sheathing below. Ice damming on soffits — particularly on north-facing exposures — can force water behind fascia and into the top edge of siding installations. Any storm damage that went unaddressed through fall is typically significantly worse by the time spring arrives, making spring inspection and repair a cycle that compounds costs for homeowners who delay.
Lombard and the broader DuPage County area have experienced documented significant hail events in multiple recent years, reflecting the region's position along the northern edge of the so-called "Hail Alley" extension that runs from Texas northeast through the Midwest. Meteorological data consistently places northeastern Illinois among the highest hail frequency zones in the Great Lakes region. For homeowners in Lombard, this means that any given year carries a meaningful probability of at least one storm event capable of damaging siding — and the cumulative effect of multiple moderate events over several years can be just as significant as a single major storm. Regular post-storm inspections are not alarmist; they are good property management practice in this climate zone.
Vinyl Siding: Hail damage on vinyl siding presents as circular impact marks ranging from minor surface dents to full-thickness cracks and punctures. The characteristic "spiderweb" crack pattern — where the vinyl cracks outward from a central impact point — is a definitive indicator of hail impact. On flat panel surfaces, look for circular depressions even when the vinyl hasn't cracked all the way through; these indicate the panel has been compromised structurally and will fail sooner than undamaged sections nearby. Wind damage on vinyl typically appears as lifted panel edges, panels that have popped out of their interlocking bottom channel, or panels that have been completely separated from the wall and blown to the ground or yard. Check butt joints, corner posts, and J-channel returns for cracking and separation, as these transition points are particularly vulnerable to impact and wind stress.
James Hardie Fiber Cement: Fiber cement siding is significantly more impact-resistant than vinyl, but it is not indestructible. Hail damage on Hardie products typically presents as surface fractures, chips at the face of the panel, or cracks that run diagonally from the impact point. Because Hardie's dense composition doesn't dimple like vinyl, the damage is sometimes less visually obvious from the ground, making a close-up inspection critical. Chipped factory finish — HardieZone or ColorPlus coating — that exposes raw fiber cement substrate is a functional issue because bare fiber cement will absorb moisture rapidly if not sealed or repaired. On Hardie installations, also inspect caulked joints at windows, doors, and corner boards, as hail impact can crack caulk lines that then allow water infiltration.
LP SmartSide Engineered Wood: LP SmartSide products combine wood fiber with resin binders and a textured overlay for weather resistance. Hail and impact damage on SmartSide may appear as dented or fractured surface texture, cracked overlay coating, or in severe cases, full panel penetration. Because SmartSide's wood-fiber core is moisture-sensitive when the protective coating is breached, prompt repair of any LP panel damage is particularly important. Check the bottom edges of LP panels and any horizontal joints carefully, as these areas are most susceptible to moisture infiltration when protective layers are compromised.
Soft-Metal Corroborating Evidence: One of the most reliable tools for confirming hail damage to a home is the condition of soft-metal components: aluminum gutters and downspouts, aluminum or galvanized window wraps, and the fins of central air conditioning condensers. These materials dent easily and permanently from hail impact. If your gutters show consistent dimpling across all four elevations of your home, that's strong physical evidence that hailstones of sufficient size struck your property during a storm — the same stones that left visible marks on gutters were hitting your siding simultaneously. Adjusters and attorneys recognize soft-metal evidence as a key component of storm damage documentation, and Allied's inspectors photograph and document all soft-metal damage as part of every inspection.
The Chalk-Circle Method: Professional inspectors sometimes use chalk to circle individual impact marks on siding panels to count and photograph impact density. On vinyl, a typical hail event of damaging severity will produce multiple impacts per square foot of panel surface on exposed elevations, with impact density decreasing on sheltered (lee-side) elevations. This impact pattern — high density on north and west exposures, decreasing on south and east — is consistent with a windblown hail event and helps confirm the damage is storm-related rather than pre-existing or impact from other sources.
Cosmetic vs. Functional Damage: Not all storm damage to siding is immediately functional — some impacts leave visible marks without compromising the panel's weather-resistance performance. However, distinguishing cosmetic from functional damage requires expertise. A surface dent in vinyl that hasn't cracked through is technically cosmetic but may indicate a structural weakness that fails under the next freeze-thaw cycle. A chip in Hardie's factory finish is cosmetic in appearance but functional in consequence because it allows moisture to reach the substrate. Allied's inspectors make this distinction clearly in every report we prepare, so homeowners and their insurance carriers have an accurate, evidence-based assessment rather than guesswork.
When to Call: If you experienced a storm with any of these signs — golf-ball-or-larger hail reports in your zip code, wind gusts over 45 mph, or visible debris damage to your yard — call Allied for a free inspection regardless of whether you can see obvious damage from the ground. Many significant siding damage events are not visible without ladder access and close-up inspection. Call (800) 792-0212 or request your free inspection online.
Allied Emergency Services guides Lombard homeowners through every stage of the storm-damage siding repair process — from the first phone call to the final walkthrough. Here's how it works.
From the moment you call, our clock is running. We dispatch an inspector to your Lombard property within 60 minutes. If your siding has been breached in a way that allows active water infiltration — a large puncture, missing panels, or wind-torn sections — our crew immediately installs temporary weather protection to stop further damage while we assess the full scope. Emergency stabilization is included at no charge when we perform the subsequent repair or replacement work. We document the property's condition on arrival, including time-stamped photographs, as part of the complete damage record.
Our inspection is systematic and thorough. We photograph every elevation of your home at multiple distances — full elevation shots, mid-range panel views, and close-up impact documentation. We document soft-metal evidence on gutters, downspouts, and window wraps. We measure impact density on affected panels and note the distribution pattern across exposures. We inspect all trim, soffit, fascia, corner posts, and J-channel in addition to field panels. The complete documentation package — photographs, measurements, written scope, and weather event verification — is compiled and provided to you in a format that supports your insurance claim process.
Once you've filed your claim with your homeowner's insurance carrier, Allied works alongside the process to ensure your documentation is complete and your adjuster has what they need to evaluate the loss. We can be present at your property during the adjuster's inspection to answer technical questions about our findings and scope. If the initial adjuster scope differs significantly from our assessment, we prepare a supplemental documentation package that addresses any discrepancies. We work within the insurance process and communicate directly with your claims representative when you authorize us to do so. Remember: Allied is a restoration contractor, not a public adjuster — we document and repair, your insurance company determines coverage.
Once scope and materials are approved, our installation crews get to work. For partial repairs, we stage the exact matching panels and trim, complete the installation in a single continuous session for consistent color and alignment, and remove all old panels and debris from your property the same day. For full replacements, we coordinate material delivery, conduct tear-off and sheathing inspection, install new housewrap, and complete installation in the scheduled timeframe. We keep you informed of daily progress, contact you immediately if we discover any unforeseen conditions (like sheathing damage under the old siding), and never proceed with scope changes without your authorization.
Before we close out your project, our project manager conducts a complete final walkthrough with you on-site. We inspect every panel, every trim transition, every caulked joint, and every corner for quality and alignment. We verify that the job site is completely clean — no old panels, no nails, no debris anywhere on your property. We review the manufacturer's warranty documentation for your new siding material and explain what maintenance steps (if any) will protect that warranty over time. Only when you are fully satisfied do we present final paperwork. Your investment in Lombard's harsh storm climate deserves to be protected by work done right, not just work done fast.
Real reviews from real customers in the Lombard area and surrounding DuPage County communities.
"After the June storm came through and knocked siding off the back of our house, I was worried we'd be waiting weeks for someone to even call us back. Allied was at our house within an hour of my call, covered the exposed area right away, and had us fully matched and repaired within two weeks. The color match on the vinyl was perfect — you genuinely cannot tell where the new panels are. Zero complaints, would absolutely call them again."
"We had a full hail storm come through and I honestly wasn't sure if we had damage or not. Allied came out, did a complete inspection at no charge, and found significant damage on the north and west sides that I never would have seen from the ground. Their documentation was incredibly thorough — I sent it directly to my insurance company and the claim moved quickly. The whole replacement process was smooth and professional from start to finish. Highly recommend to anyone in the area."
"We have an older home near St. Charles Road and our siding profile was basically impossible to match — I'd been told by two other contractors that we'd have to replace everything. Allied found an equivalent profile through one of their suppliers and did a seamless partial repair that looks completely natural. Their crew was also incredibly clean and professional — you'd never know they were there except that the siding looks great. Best contractor experience we've had in fifteen years of home ownership."
