If you live in Texas, Oklahoma, Colorado, or any of the storm-prone states we serve, you’ve probably sheltered indoors during a hailstorm and wondered: how bad is it up there? The answer depends on three things — the size of the hail, how much of it fell, and what your roof is made of.
This guide covers everything homeowners need to know about hail damage on a roof: whether your roof is actually at risk, what damage looks like on different materials, which signs to check for yourself, and when to call a professional.
Will Hail Actually Damage My Roof?
Not every hailstorm damages a roof. Light hail — the kind that sounds loud but stays small — typically won’t create insurance-worthy damage on a well-maintained roof. The critical threshold is around 1 inch in diameter. Once hailstones reach roughly quarter size or larger, they carry enough mass and velocity to cause real structural harm to roofing materials.
That said, even sub-threshold hail can accelerate aging. Repeated impacts from smaller stones gradually strip granules from asphalt shingles, wearing down the UV protection layer and shortening overall roof life. So while you may not have a leak today, that cumulative wear matters — especially as the roof approaches the end of its service life.
A useful rule of thumb: if you’re seeing hail damage elsewhere around your property — dented gutters, dimpled A/C fins, damaged window screens, or dings on your car — there’s a very good chance your roof took a hit too. Hail doesn’t selectively miss roofs.
Hail Size and What It Does
The National Weather Service categorizes hail by both size and threat level. Here’s what each size category means for your roof.
Small hail (under 1″ / pea to dime size). This size typically appears in low-threat storms. On its own, it shouldn’t cause immediate structural damage, but if the storm dropped significant volume or your roof is already aging, a quick inspection is a reasonable precaution.
Large hail (1″ to 1¾” / quarter to golf ball size). This is the category where roof damage becomes reliably probable. Shingles lose granules, develop compressed dents, and can crack. Gutters and downspouts often sustain visible dents at this size. The damage is real even when it’s not immediately obvious — and it warrants a professional inspection.
Very large hail (1¾” to 2¾” / golf ball to baseball size). Damage at this size is hard to miss and often severe. Shingles crack and fracture, metal components dent significantly, and underlying roof deck layers can be affected. If your area received hail in this range, call for an inspection promptly — don’t wait for a leak to confirm what the storm likely already did.
Giant hail (over 2¾” / softball or grapefruit size). This is catastrophic hail. It’s rare, but when it occurs — particularly across the Texas and Oklahoma plains — it can destroy roofing systems outright. If you experienced this size of hail, prioritize your safety first, then call us immediately.
What Hail Damage Looks Like: By Material Type
Hail damage doesn’t look the same on every roof. Knowing what to look for on your specific material helps you make a faster, more accurate assessment.
Asphalt shingles. This is the most common residential roofing material and one of the most visible when damaged. Look for: circular impact marks or bruising in the shingle surface, granule loss creating bald or thin spots (check your gutters — granule buildup after a storm is a strong indicator), cracking or fracturing at impact points, curling or lifting at shingle edges, and exposed dark substrate where the granule layer has been knocked away. Dents in asphalt can look like random dark spots scattered across the field of the roof — not a pattern, not aligned with any seams.
Metal roofing. Metal is more impact-resistant than asphalt, but it still shows damage. Look for circular dents or dimples across panels and ridges, especially on softer aluminum systems. Steel panels are harder to dent but may show cosmetic damage that can compromise coatings over time. Impact marks on metal are often subtle — what looks like a scuff from the ground can be a genuine dent when viewed up close.
Tile roofing. Concrete and clay tile can crack, fracture, or break outright under large hail. Cracked tiles may not be visible from the ground and can allow water infiltration at the break point before any interior signs appear. A tile roof that “looks fine” from the street can have multiple cracked tiles that only become apparent with a close inspection.
Wood shake. Wood shake shingles can split, splinter, or crack at impact points. The damage often looks like fresh, lighter-colored splits against the weathered gray of the shake surface. Splits that run with the grain are often normal weathering; splits that cut across the grain at a single point are typically impact damage.
Beyond the Roof Surface: Other Damage to Check
A roof inspection after a hailstorm shouldn’t stop at the shingles. Several other components deserve a close look.
Gutters and downspouts. Gutters are among the clearest indicators of hail severity. Dents, holes, cracked seams, and knocked-loose sections all point to a significant storm. If your gutters are full of granules after a storm, that’s direct evidence your asphalt shingles took a beating. Damaged gutters also affect water drainage — a problem that compounds quickly.
Roof flashing. The metal flashing around chimneys, vents, skylights, and valleys can dent or separate under hail impact, creating potential water entry points even when the shingles themselves look intact.
Fascia and soffits. Hail can dent or crack these aluminum and vinyl components. Damage here is often visible from the ground and can be a useful proxy for assessing overall storm severity before a roofer arrives.
Interior Signs That Hail Damage Has Already Progressed
If hail damage goes unaddressed, it eventually works its way inside. Watch for these interior warning signs — especially if you’ve had a recent storm and haven’t had the roof inspected yet.
Water stains or discoloration on ceilings and upper walls can indicate active or intermittent water intrusion. The stain may not appear directly below the roof penetration point — water travels along structural members before dripping, so the visible stain may be feet away from the actual entry point.
In the attic, look for damp or compressed insulation, dark streaks on rafters or sheathing, or visible light coming through the decking. Any of these indicates the roof system has been compromised.
If you’re seeing interior signs, the roof has likely been leaking for some time. Don’t wait — call for an inspection.
What to Do After a Hailstorm
Don’t go on the roof yourself. Post-storm roof surfaces can be slippery, structurally unstable, or both. Hail damage assessment is best left to a professional with the right equipment and training.
Document what you can from the ground. Photograph dents in gutters, damaged window screens, dings on the A/C unit, and any visible shingle irregularities. This documentation supports your insurance claim.
Call your insurance company to report potential damage. Most homeowner’s policies have a window for storm damage claims. Acting quickly preserves your options.
Schedule a professional roof inspection. A trained roofing contractor can identify damage that isn’t visible from the ground, document findings in a format suitable for an insurance adjuster, and give you an accurate picture of what repairs are needed — and what they’ll cost.
At Roof Experts, our inspections are free. We’ll assess your roof thoroughly, document the damage, and walk you through your options without pressure. If there’s nothing to report, we’ll tell you that too.
