Cracked and punctured siding lets moisture reach sheathing and framing — document it and fix it right. Allied Emergency Services responds within 1 hour to Northbrook storm damage calls, 24 hours a day, 7 days a week.
When hail cracks or punctures siding panels, the damage is rarely limited to what you see on the surface. Moisture wicks rapidly behind compromised panels, reaching the housewrap, OSB sheathing, and dimensional framing beneath. Once moisture enters the wall cavity, hidden rot and mold begin developing out of sight — problems that can cost far more to remediate than a timely siding repair. Illinois homeowners have a limited window to document storm damage for insurance purposes; delays in inspection and documentation can complicate the claims process and potentially result in denied coverage.
There is another time-sensitive issue that many Northbrook homeowners don't consider: siding profiles get discontinued. Manufacturers regularly retire colors and profiles, which means the longer you wait, the harder it becomes to source matching panels for a partial repair. What is a manageable partial repair today could become a full-elevation replacement tomorrow — simply because the matching product is no longer available. Energy loss is also a real consequence of compromised siding; gaps and cracks in your building envelope allow conditioned air to escape and outside air to infiltrate, driving up your heating and cooling costs season after season.
The bottom line: acting quickly protects your home, preserves your insurance options, and keeps repair costs as low as possible. Call Allied at (800) 792-0212 for a free inspection — our Northbrook team responds within one hour.
Northbrook is a well-established suburb in the northern reaches of Cook County, bordered by the Des Plaines River to the east and an interconnected network of forest preserves that give the community its signature wooded character. The village encompasses a diverse range of residential neighborhoods — from the mature tree-lined streets of Shermer Estates and the Ranch Triangle near Waukegan Road, to the newer construction around Techny Road and the established mid-century homes that line Meadow Lane and Landwehr Road near the Northbrook Court shopping district. Glenbrook North and Glenbrook South high schools anchor two of the most recognizable areas of the community, with surrounding neighborhoods characterized by the large deciduous tree canopy that, while beautiful, presents a real hazard during severe weather.
Northbrook's location in northeastern Illinois puts it squarely in the storm corridor that tracks severe weather northeastward off Lake Michigan and from the southwest out of the central Illinois plains. The village experiences a full range of damaging weather types: spring hailstorms that drop golf ball-sized ice from supercell thunderstorms, summer derecho-style straight-line winds that can exceed 60 mph, and fall ice storms that load tree branches until they fail against roofs and siding. The proximity of the North Shore Channel and the numerous retention ponds throughout the village means that drainage during heavy rain events can be substantial — further compounding the urgency of addressing siding breaches that allow water infiltration into wall cavities.
The Techny Basin area in the western portion of the village and the neighborhoods near Dundee Road and Willow Road frequently see storm tracks that funnel severe weather directly through the community. Homes along Pfingsten Road, Landwehr Road, and the residential sections south of Lake-Cook Road have historically experienced significant hail events that affect roofs and siding simultaneously. Our crews know these streets and understand the specific vulnerabilities of the housing stock in this area.
From single-panel hail repairs to complete whole-home re-siding projects, Allied Emergency Services has the crew, materials, and expertise to restore your Northbrook home to pre-storm condition — and often better.
Hail leaves a signature pattern on siding that trained inspectors recognize immediately — circular impact cracks, spider-web fractures at the stress point, and punctures in older or brittle panels. Wind damage manifests differently: torn panels that have been lifted at the locking channel, cracked laps from debris strike, or complete panel blow-off on high-exposure elevations. Our storm damage repair teams address all of these scenarios, working quickly to stabilize the building envelope and prevent water intrusion from compounding the original storm damage.
When hail or wind has affected the majority of your home's exterior, or when an aging siding system has reached the end of its useful life, full replacement is the right investment. We install three primary siding categories for Northbrook homeowners. Vinyl siding remains the most popular choice, offering a broad range of colors and profiles at a competitive installed price, with modern formulations that resist impact and UV fading far better than products from a decade ago. LP SmartSide engineered wood offers superior impact resistance and a realistic wood appearance with fiber cement's durability edge. James Hardie fiber cement is the premium option — fire-resistant, moisture-resistant, and backed by one of the strongest warranties in the industry.
Partial siding repairs require a level of skill and product knowledge that separates experienced restoration contractors from general handymen. The challenge is not just finding the right color — it is finding the right profile, the right exposure width, and the right sheen level to blend seamlessly with undamaged panels that have weathered in place for years. Newer panels are always brighter than aged panels, which means color matching is part science and part art. Our team carries sample boards from multiple manufacturers and sources through specialty distributors to find the best possible match for your existing siding. When an acceptable match cannot be achieved, we document this finding thoroughly and can recommend a full-elevation replacement that creates a consistent appearance.
Thorough documentation is the foundation of any successful insurance restoration project. When we inspect a storm-damaged Northbrook home, we systematically photograph every elevation, document the location and density of hail impacts, measure the affected square footage, and assess corroborating damage on soft metals — gutters, downspouts, window wraps, and AC fins — that helps establish the storm date and severity. We produce a comprehensive damage report that your insurance company's adjuster can use to evaluate the scope of repairs. As restoration contractors, we perform this documentation as part of our free inspection service. We are not adjusters and we do not negotiate with insurers on your behalf, but our thorough documentation gives adjusters the information they need to assess your claim accurately.
Northeastern Illinois — and Northbrook specifically — sits in one of the most active severe weather corridors in the Midwest. Understanding the storm history and patterns that affect this community helps homeowners recognize when their siding may have sustained damage that warrants a professional inspection.
The most destructive hail events in the Northbrook area typically occur during the spring severe weather season, when cold air from Canada collides with warm, moist Gulf air over the Illinois plains. Supercell thunderstorms that develop along these boundaries can produce hailstones ranging from pea-sized (0.25 inch) to golf ball-sized (1.75 inch) and larger. Cook County and the north shore suburbs see multiple documented hail events most years during this window. Quarter-to-half-inch hail is sufficient to fracture older or UV-brittle vinyl siding, while golf-ball hail can puncture even newer installations and cause significant damage to fiber cement products.
Northbrook's position along the Lake Michigan shoreline corridor creates a complex wind environment during summer storm systems. Derecho-style events — lines of severe thunderstorms producing sustained damaging winds — can push through northeastern Illinois with wind gusts exceeding 60 to 80 mph, strong enough to peel siding panels from walls, drive debris through panels, and compromise trim and soffit systems. The mature tree canopy in neighborhoods like Shermer Estates and the areas surrounding Techny Road amplifies this risk, as downed limbs and trees become projectiles in high-wind events. Following major summer derechos, our teams typically respond to dozens of Northbrook properties within 24 to 48 hours of the event.
Northbrook's proximity to Lake Michigan extends its severe weather season well into autumn. Lake-effect moisture combined with early cold fronts can produce ice storms that coat everything in a half-inch or more of ice — loading tree branches until they snap and fall against roofs and siding, and creating freeze-thaw cycles that work moisture into existing cracks and gaps in the siding envelope. Properties along the Des Plaines River corridor and near the forest preserves are particularly exposed to ice-loaded tree failure. These events frequently cause siding damage that goes undetected until spring, by which point moisture has had months to work into the wall assembly.
Many Northbrook homeowners discover their siding was damaged in a previous storm only when water staining appears on interior walls — by which point remediation costs have multiplied significantly. A post-storm professional inspection is the only reliable way to assess the true condition of your siding and underlying wall assembly. Our inspectors look beyond surface appearance to assess the integrity of the housewrap, the condition of the sheathing, and any signs of moisture infiltration in the wall cavity. This is the only way to get ahead of the hidden damage that storm events leave behind.
Identifying hail and wind damage on siding requires knowing what to look for on different material types — and understanding the difference between cosmetic imperfections and functional damage that compromises your building envelope. Here is a practical guide to inspecting your own siding after a severe weather event, and knowing when to call for professional evaluation.
Vinyl siding is the most common exterior cladding on Northbrook homes, and hail damage on vinyl has a distinctive appearance that experienced inspectors identify immediately. Hailstone impacts leave circular cracks or spider-web fractures at the point of contact. On older vinyl that has become brittle from UV exposure, even smaller hailstones can cause punctures — actual holes that penetrate the panel completely and allow direct water entry into the wall cavity. Impact marks often align consistently with the storm's direction of travel, concentrating damage on the west or southwest elevation in typical Illinois storm tracks, while north-facing elevations may show less visible damage.
One important distinction: not all visible marks on vinyl are hail damage. Older vinyl develops chalking, crazing, and oxidation that can mimic impact marks to the untrained eye. The difference is that hail impacts cause a physical fracture of the material — you can feel the crack with a fingernail, and there is often a subtle deformation of the panel surface at the impact point. Our inspectors use a combination of visual assessment and hands-on examination to distinguish genuine hail strikes from weather-related surface wear.
Fiber cement and engineered wood siding handle hail differently than vinyl. James Hardie products are Class 4 impact-rated, meaning they are engineered to resist significant hail impact — but they are not impervious. Large hail (1.5 inch and larger) can cause chipping of the factory finish, hairline fractures in the cement board, and in severe cases, cracking through the full panel thickness. Damage to fiber cement is sometimes subtle: paint chip-off at the impact point that exposes raw cement board to moisture. Because fiber cement is moisture-sensitive at its edges and where the factory finish is compromised, even seemingly cosmetic paint damage can become a functional problem over time. LP SmartSide products can show edge separation and panel swelling at impact points where the protective coating is breached.
Wind damage typically manifests as lifted panels where the locking channel has been disengaged by uplift forces, cracked laps where wind-driven debris has struck at an angle, or complete panel blow-off on high-exposure corners and gable ends. Wind-lifted panels that fall back into position may appear undamaged from the street, but the locking channel engagement is compromised and the panel will lift again in the next wind event — meanwhile, rainwater is getting behind the panel every time it happens. Check your corners, rakes, and gable trim carefully after any wind event, as these are the highest-stress locations on a home's exterior.
One of the most important steps in any storm inspection is checking your soft metal surfaces — gutters, downspouts, window wraps, fascia, and AC condenser fins. Aluminum and galvanized metal surfaces dent cleanly and consistently from hail impacts, leaving a pattern of circular dents that correspond directly to the size and density of the hailstones that hit your property. If your gutters show consistent quarter-inch dents on a specific date following a known storm, that is objective evidence that your property experienced hail of that size on that date. This corroborating evidence supports your insurance evaluation and helps establish the storm as the cause of any siding damage found during inspection. If you see consistent denting on your soft metals, do not delay in scheduling a siding inspection — hail large enough to dent gutters is large enough to damage siding.
Not all storm damage is equal. Some hail impacts leave surface marks that are cosmetic — visible but not actively compromising the weather barrier function of the siding. Other impacts create functional damage: actual breaches in the siding panel that allow water intrusion, lifted panels that disengage the locking system, or cracks that propagate during freeze-thaw cycles. The distinction matters for insurance purposes and for understanding repair urgency. Our inspectors document both types of damage and clearly communicate which findings represent functional impairment versus cosmetic degradation. Either type may be covered under your policy, but functional damage requires faster response to prevent secondary damage to the wall assembly.
Navigating siding damage restoration alongside your homeowners insurance policy is a process with distinct steps. Here is exactly what to expect when you work with Allied Emergency Services after storm damage to your Northbrook home.
The moment you call us, the clock starts. Our teams respond to Northbrook within one hour for active damage situations. If siding panels are missing, cracked through, or otherwise allowing water intrusion into your wall system, our first priority is stabilization — securing loose panels, installing temporary water barriers where needed, and preventing further damage before permanent repairs begin. We document conditions on arrival with photographs and notes that establish the pre-repair state of your home.
Before any repair work begins, we conduct a systematic elevation-by-elevation inspection of your entire home exterior. We photograph each elevation at multiple angles, document the location and density of hail impacts, record measurements of damaged areas, and inspect all soft metals for corroborating hail evidence. We also check the condition of housewrap, sheathing, and trim at accessible areas to identify any pre-existing or storm-related substrate damage. This documentation forms the basis of your insurance evaluation package.
Once documentation is complete, we provide you with a detailed scope of work and materials specification. If you have not yet contacted your insurance company, this is the right time to file your claim and request an adjuster visit. We make ourselves available to be present during the adjuster's inspection, so we can walk through the documentation and ensure that all damage identified in our inspection is considered. We do not negotiate or settle claims — that is between you and your insurer — but we provide complete and accurate information to support an accurate assessment of your damage.
Once your claim is approved and materials are ordered, we schedule installation at your earliest convenience. Our crews are experienced with all major siding products and installation systems, working efficiently to minimize disruption to your household. We manage material delivery, protect your landscaping and adjacent surfaces during removal of damaged siding, properly dispose of old materials, and install new siding to manufacturer specifications — which is critical for warranty compliance and code conformance. For insurance projects, we work within the approved scope and communicate directly with you about any supplemental findings that arise during installation.
Before we consider any project complete, we conduct a comprehensive final walkthrough with the homeowner. We inspect every panel, every seam, every piece of trim, and every transition detail to ensure the installation meets our quality standards and yours. We verify that all locking channels are properly engaged, that all penetrations are properly caulked and sealed, and that the finished product presents the appearance and performance you expect. We leave your property clean and provide warranty documentation for all installed products. Our job is not done until you are completely satisfied.
Reviews represent typical customer experiences.
"After a major hailstorm came through Northbrook in late spring, I had no idea my siding had been damaged. Allied came out within the hour and showed me exactly what to look for — the cracks on the west elevation were subtle but real. They documented everything professionally, and my insurance company approved the claim without any hassle. New siding looks fantastic."
"Our home near Glenbrook North had an older siding profile that we were told was discontinued. Allied sourced matching panels through a specialty distributor and the repair on the north elevation blends in perfectly. They were honest with us throughout the whole process about what was achievable and what wasn't — refreshing to work with a contractor who doesn't overpromise."
"We had wind damage from a derecho that pulled siding panels off two corners of our house. Called Allied at 9pm and they had someone at our door within 45 minutes to assess and stabilize the damage. Full repair was done within a week, worked perfectly with our insurance claim, and the crew cleaned everything up completely before they left. Couldn't ask for a better experience."
