The Storm Passed. Your Roof Might Not Have.
What You’ll Learn Minnesota summers have a way of reminding you who’s in charge. One afternoon, it’s 85 degrees and clear; by evening, a fast-moving cell has pushed through Eden Prairie and dropped hail the size of marbles across the southwest metro. Most homeowners walk outside afterward, look around the yard, pick up a few branches, and go back inside. The roof, if it crosses their mind at all, gets a quick glance from the driveway before they decide it looks fine. That glance from the driveway is almost always wrong. Hail damage to an asphalt shingle roof doesn’t look like a hole. It doesn’t look like a missing shingle. More often, it looks like nothing at all from 20 feet below. In most cases, it is a network of small impact craters that have knocked the protective granule coating off the shingle surface, exposing the asphalt mat beneath to UV degradation and moisture infiltration. Left alone, that damage doesn’t stay invisible. It accelerates. If a significant storm has moved through your area in the last six months and you haven’t had your roof inspected, there’s a reasonable chance you’re sitting on a claim you don’t know about yet. What Hail Does to a Shingle To understand why hail damage is hard to spot and easy to underestimate, it helps to know how an asphalt shingle works. The granules embedded in the surface aren’t decorative. They’re a UV barrier. They protect the asphalt mat below from the sun’s breakdown of the petroleum-based material that holds the shingle together. When hail knocks those granules loose, it creates what roofers call “soft spots” in the shingle. The asphalt mat is now exposed. It starts to dry out, crack, and curl. In Minnesota, where temperature swings between summer highs and January lows can exceed 100 degrees Fahrenheit over the course of a year, that exposed mat deteriorates faster than it would in a milder climate. Freeze-thaw cycling does the rest. A shingle that looks functional in October can be cracking by March. By the following spring, you will have water entry. What makes this particularly consequential for Eden Prairie homeowners is timing. If you miss the insurance claim window (most policies require you to file within one year of the storm date, though policies vary), you’re looking at paying out of pocket for a replacement that could have been fully or mostly covered. Signs You Can See from the Ground You don’t need to go up on the roof to get a preliminary sense of whether your home sustained significant damage. Several reliable proxy indicators suggest a closer look is warranted. Start with your gutters and downspouts. After a hailstorm, granules shed from impacted shingles collect in gutters in significant quantities. If you scoop out your gutter and find what looks like coarse black sand, that’s granule loss. Some granule shedding is normal in aging shingles, but a large accumulation after a specific storm event is a different story. Look at soft metal surfaces around your property. Air conditioner fins, gutter aprons, metal flashing, mailboxes, and window screens all register hail impacts as small circular dents. These don’t lie. If your AC unit looks like it was used for target practice, your roof was in the same storm. Wooden surfaces, particularly fence rails, deck boards, and wood fascia, show fresh impact marks in the form of circular, splintered indentations without weathered edges. If those marks look fresh and unweathered, they happened recently. None of these observations definitively confirms roof damage, but any one of them is sufficient justification to schedule a professional inspection before the insurance clock runs down. What a Real Inspection Covers There is no substitute for a trained eye on the roof surface. From ground level, satellite imagery, or a drone image, you cannot reliably assess shingle-level hail damage. The defining characteristic of a legitimate hail impact on an asphalt shingle is a soft, spongy indentation where the granules have been displaced and the asphalt mat has been disturbed. You find this by walking on the roof, running your hand over the surface, and knowing what healthy shingle resistance feels like compared to compromised shingle resistance. A thorough inspection should cover the entire roof surface on all slopes, all ridge caps and hip caps (which receive the most exposure), all flashing points around chimneys, skylights, and pipe penetrations, and all valley areas. A contractor who spends eight minutes on your roof has not inspected it. The inspection should also document everything photographically. If you’re filing a claim, your adjuster will want photographic evidence of impacts in multiple locations across multiple slopes. Date-stamped photos taken during a professional inspection are far more useful to your claim than photos you take yourself from the edge of a ladder. How the Insurance Claim Process Works Filing a hail damage claim is not complicated, but there are ways to make it harder than it needs to be. The most common mistake homeowners make is calling their insurance company before they’ve had a contractor inspect the damage. The sequence matters. Get your inspection first. A contractor who regularly works with storm claims will document the damage in a format useful to an adjuster, note the storm date, and confirm whether the damage meets the claim threshold. You go into the insurance call knowing what you have, which is a better position than calling to say, “I think maybe there might be damage.” Once you file, your insurer will send an adjuster to assess. Having a contractor present during the adjuster visit is not required, but it is smart. An experienced roofing contractor can identify specific impact points, reference storm data for your area, and ensure the adjuster’s scope of work reflects the actual damage rather than the minimum defensible assessment. In Minnesota, most policies cover hail damage under the dwelling coverage portion of your homeowner’s insurance, subject to your deductible. Whether you receive replacement cost value or actual cash value (which accounts for depreciation)
