How to Spot Hail Damage on a Roof in Plano Without Climbing Up

On the afternoon of April 11, 2016, a supercell crossed North Texas and reached its peak strength over Collin County. The National Weather Service in Fort Worth later recorded a 5.25-inch hailstone from that storm, the largest on record for its forecast area, and reported that about 80% of homes in Wylie were affected, with damage topping $300 million. Nobody needed a checklist that night.

Most hail days in Plano look nothing like that. The stones are smaller, the storm passes in minutes, and the next morning the roof looks unchanged. That is when knowing how to spot hail damage on a roof matters, because the damage that shortens a roof's life is usually subtle and scattered. This guide covers the checks you can make safely from the ground, in the order that makes sense after a storm.

Key Takeaways

• The size of the hailstones that fell in your yard is the first and most useful clue to whether the roof was hurt.
• Gutters, downspouts, vents and the AC condenser dent before shingles visibly fail, so soft metals are the easiest evidence to read from the ground.
• Fresh asphalt granules collecting at downspout outlets after a storm point to impacts on the slopes above.
• Hail bruises are dark, roughly round marks scattered at random; wear, blistering and foot scuffs tend to follow patterns.
• Walking a wet or freshly hit roof is the riskiest part of checking it; binoculars and a phone zoom do most of the work.

The Hailstones in Your Yard Are the First Clue

Hail size is the best early predictor of roof damage, so measure it before it melts: set a few of the largest stones beside a coin or tape measure and photograph them. The National Weather Service size chart translates common comparisons into inches: a quarter is one inch, a ping pong ball is an inch and a half, a golf ball is an inch and three quarters, and a baseball is two and three quarters.

Size matters because shingles respond to it. The National Weather Service treats one inch as the line for severe hail, and engineering work on roof damage has long held that stones below that size rarely cause functional damage to a sound shingle on their own. Once stones reach golf ball size, the odds of bruised or fractured shingles climb quickly, especially on slopes facing the direction the storm came from.

Note the time the hail fell, too. Plano sends severe weather alerts through NOAA Weather Radio, its Outdoor Warning System and Wireless Emergency Alerts, and an alert's timestamp helps match your photographs to a specific storm later.

Keep Your Feet on the Ground for Every Check

A roof inspection by a homeowner should happen from the lawn, the driveway and the attic hatch, not from the shingles. Roofs after a storm are wet, littered with loose granules and debris, and often steeper than they look from below, particularly on two-story homes. A fall from an eave costs far more than any hail repair, and walking on bruised shingles can crack them further.

You lose very little by staying down. A pair of ordinary binoculars and the zoom on a modern phone camera will show dented vent caps, missing granules and damaged ridge caps from across the street. Work each side of the house in turn, and check again in low morning or evening light, when small pits cast shadows that flat midday sun hides.

Soft Metals Show Dents Before Shingles Do

Thin metal parts of a house record hail better than anything else. Aluminum dents at impact energies that may not visibly mark a shingle, so clean gutters after a storm are reassuring and dented ones are a reason to look harder at the roof above. Walk the perimeter and check:

• Gutter tops and faces: round dents along the front lip or the face of the gutters and downspouts, often in a line where stones bounced off the roof edge.
• Downspouts: dimples on the side facing the storm, which you can run a hand over at ground level.
• Air conditioner condenser: flattened or crushed fins on top of the outdoor unit, one of the most reliable ground-level indicators.
• Roof vents and pipe caps: dents in turtle vents, turbine vents and ridge vent covers, visible through binoculars.
• Window wraps, screens and painted trim: dents, tears and paint chips on the same side of the house.

Direction is evidence too. If dents cluster on the north and west faces, the slopes facing that way took the heaviest hits; study those first.

Granules at the Downspouts Mean the Shingles Were Hit

Asphalt shingles are topped with ceramic-coated mineral granules that shield the asphalt from sunlight, and hail knocks them loose. After a storm, look at the splash blocks, the ground under each downspout outlet and the edges of the driveway for small piles of coarse, dark, sand-like grit. A heavy wash from one or two downspouts points to the slopes draining into them.

Small hail is not harmless to granules either. Research from the Insurance Institute for Business and Home Safety, published in Frontiers in Materials, found that repeated sub-severe hail, stones under an inch, accounted for most granule loss in their tests and could add up to more loss than a single two-inch impact. Shingles that had weathered and taken those smaller hits were roughly ten times more susceptible to damage from a later severe storm.

Some shedding is normal on a brand-new roof as excess granules wash off. What matters is a sudden, larger amount appearing right after the hail.

Hail Bruising Looks Random, Wear Looks Patterned

A hail bruise on an asphalt shingle is a roughly circular spot where granules have been knocked away, exposing darker asphalt or the mat underneath. Fresh hits often look darker and slightly shiny compared with the surrounding shingle. Through binoculars you are looking for those dark spots scattered without any order across a slope.

Other conditions get mistaken for hail, and pattern is the giveaway:

• Blistering: small raised bubbles or pits from trapped moisture or heat, usually spread evenly across sun-facing slopes.
• Normal aging: gradual, even granule loss, curling tabs and cracking, worst on the oldest or most exposed faces.
• Foot traffic and tool marks: scuffs in lines near ridges, vents or satellite mounts where someone walked.
• Wind damage: creased, lifted or missing tabs, typically along rakes, ridges and edges rather than in the middle of a slope.

Hail ignores those patterns. Genuine damage shows up as random impacts across a slope, concentrated on the side facing the storm and usually matched by fresh dents in the metal on that side.

The Attic and the Rest of the Lot Fill In the Picture

The attic tells you whether hail has opened the roof, not just marked it. From the hatch, with a strong flashlight in daylight, look for pinpoints of light through the decking, damp sheathing and wet insulation, and check ceilings again after the next rain.

Outside, walk the fence line, siding, patio furniture and any vehicles left out. Collateral damage confirms hail size and direction. Photograph each item with something for scale and keep the images with your hailstone photos.

Write It Down Before the Door Knocks Start

After hail moves through Collin County, door-to-door roofers tend to follow within days, and a written record with dated photographs gives you something solid to weigh against their claims. The Texas Department of Insurance advises homeowners to get more than one bid, check references, avoid paying in full up front, and walk away from any contractor offering to waive a deductible, which is illegal under Texas law.

When the ground checks add up to likely damage, the next step is a close look by someone who belongs on the roof. Our storm and hail damage roof repair work starts with marked and photographed impacts, and a roof inspection from Roofing Plano Texas gives you a written summary you can keep whatever you decide.

Hail Damage Questions Plano Homeowners Ask

Can a roof have hail damage that is invisible from the ground?

Yes. Small bruises and fractured shingle mats are often impossible to see even with binoculars, which is why soft-metal dents and granule washout are used as indirect evidence. When those clues are present, only a close inspection confirms the shingles' condition.

How soon after a storm should I check for hail damage?

Check the same day or the next morning if you can. Hailstones melt, the next rain washes granule piles away, and fresh bruises weather into something harder to tell from older wear.

Is pea-size or penny-size hail worth worrying about?

A single storm of small hail rarely causes functional damage to a sound asphalt roof on its own. The IBHS research suggests repeated small hail still strips granules and makes shingles more vulnerable to the next big storm, so it is worth noting each event even when the roof looks fine.

Do dented gutters mean the roof is damaged?

Not automatically. Gutters dent at lower impact energy than shingles fail, so dents mean hail was big enough to be worth a closer look, not that the roof needs replacing. They are most telling when they line up with granule loss and condenser damage on the same side of the house.
