Lewisville TX Roofing: Nineties Shingles Under Denton County Hail

Lewisville was incorporated in 1925 and filled in slowly, in layers — after the dam closed off Lewisville Lake in the mid 1950s, again after DFW Airport opened in 1974, again around the mall that arrived at Round Grove Road and I-35E in 1989. That is a different history from the towns further north, and it produces a different roof problem. Lewisville is not a city of five-year-old subdivisions waiting for their first hailstorm. It is a city whose shingles have already been through several.

The census numbers make the point better than adjectives do. Of roughly 55,900 housing units, the largest single build decade is the 1990s. About 52 percent of everything standing here predates the year 2000 and about 70 percent predates 2010, while under one unit in ten went up in 2020 or later. Much of the recent jump in the city’s population came from annexing Castle Hills in November 2021 rather than from new construction. Put plainly: the median Lewisville roof is either the original covering or its first replacement, and it is old enough that its age is now part of the diagnosis.

That matters because asphalt does not fail on a schedule — it fails when age and weather meet. A shingle from a 1990s subdivision has spent a quarter century thermally cycling in Texas heat. Its mat has gone brittle, the sealant strips that bond one course to the next have dried, and its granule cover has thinned. A roof in that condition does not need a record hailstone to give up. An ordinary one will do it.

What Denton County Hail Actually Does Up Here

NOAA’s storm event records for Denton County are unusually blunt. Between 2015 and 2025 the county logged 379 separate hail events. Of those, 303 — four in five — produced stones an inch across or larger, which is roughly the size at which asphalt shingles start to bruise. A hundred and three reached 1.75 inches, sixty reached two inches or more, and the largest on the record measured 5.9 inches.

The season is narrow and predictable. Some 84 percent of those events fell between March and June, spread fairly evenly across March, April and May, with a much smaller second bump in September and November. That is the dryline doing its annual work: spring supercells firing along the boundary and dragging hail cores east across the northern metroplex.

Reports logged inside Lewisville itself follow the same pattern in miniature. Twenty-seven hail reports over that eleven-year window, twenty-two of them an inch or bigger. The largest measured three inches, on 11 June 2023. Before that: 2.75 inches in March 2017, two inches in March 2019, 1.75 inches in March 2016 and again in May 2024. This is not somebody else’s weather being borrowed to sell a roof — it is what has actually fallen on these streets.

The damage from all of it is mostly invisible from the driveway. A stone bruises the asphalt mat underneath the surface, knocks granules loose, and cracks shingles that still lie perfectly flat. Soft metal is the honest witness: gutters, flashing, ridge caps and turbine vents dent visibly when the shingles around them give nothing away.

Wind and Heat, the Two Quieter Problems

Hail gets the attention, but the same eleven years of Denton County records carry 153 thunderstorm wind events and fourteen tornadoes. Within Lewisville there are seven wind reports, topping out at an estimated 70 mph gust on 28 May 2024 and a measured 56 mph on 8 June 2025.

Straight-line wind works the edges of a roof — ridges, rakes and hips — where it lifts and creases shingles rather than removing them outright. A creased shingle usually flops back down and looks untouched, but it is no longer sealed to the course beneath it. The next rain arriving at an angle finds the gap. On an older roof whose sealant strips have already dried, it takes considerably less wind to do this.

Heat is the slow one. Summers here run in the 90s for weeks at a stretch, cycling an asphalt roof every day of the season, and the roof that has been baked all summer meets the following March in worse shape than its birthday suggests. This is genuinely a different job from the one our Katy crews do on the Gulf Coast, where hurricane and sustained wind exposure sets the terms. In Lewisville the recurring threat is a spring hail core landing on shingles that have already spent too long in the sun.

Repair It, Replace It, or Leave It Alone

Those are three genuinely different answers, and a Lewisville roof can honestly need any of them. A run of wind-lifted shingles along one rake and a cracked pipe boot on a house from the 2010s is a roof repair, and anyone converting that into a full tear-off is selling rather than diagnosing. A 1997 roof that has surrendered much of its granule cover across four or five hail seasons is a replacement conversation, where patching the one visible spot buys a season and quietly costs you the roof you may have been owed. Leaving it alone for another few years is also a legitimate verdict and one we give regularly.

What settles it is the condition of the mat, the age of the covering and how much of each slope is affected — none of which can be read from a photograph taken at ground level. That is why the roof inspection comes first, and why it is free. A slow leak stains a ceiling long before anyone thinks about the roof, so if you have a brown ring spreading in a bedroom, that is the call to make today rather than in spring.

In North Texas the Claim Is Half the Work

Our founder came out of the insurance industry, and that is the reason this company is built the way it is. We photograph what is genuinely on the deck, show you what it means, and work the roofing insurance coverage side alongside you rather than around you. When the honest finding is that there is no claim here, you hear it before anybody starts pulling shingles off.

Two practical notes for a city sitting where Lewisville sits. First, an inspection after a spring storm is worth doing even when the roof looks fine from the yard, because on a hail roof it almost always does. Second, a serious March or April storm brings crews from several states into these subdivisions within the week, so it is entirely reasonable to ask who is standing on your porch. Our hail damage assessment and wind damage assessment pages set out what we look for and how the process runs, and the storm and insurance section covers the rest.

Twenty-Six Miles Down the Sam Rayburn

Plainly: R&S has no office in Lewisville and we are not going to pretend otherwise. We serve Lewisville from our Dallas–Fort Worth office at 108 Belden Circle in McKinney — about twenty-six miles, most of it a straight run on the Sam Rayburn Tollway, which carries SH 121 from Coppell up through McKinney. Lewisville has always sat inside the territory that office covers.

Once we are in town the orientation is easy. I-35E, signed Stemmons Freeway, is the spine of the city. FM 3040 becomes Round Grove Road and runs east and west toward Flower Mound; FM 1171 becomes Main Street; FM 407 is Justin Road and gives up its state maintenance at I-35E. For landmarks rather than road numbers: Lewisville Lake and its dam, finished in 1955; the 2,600-odd acres of LLELA below it; Old Town with the MCL Grand on North Charles Street; The Vista at Round Grove and I-35E, which most people still think of as Vista Ridge Mall; and the three A-train stations at Old Town, Hebron and Highland Village/Lewisville Lake. Schools are Lewisville ISD. Most of the city sits in Denton County with a southern slice reaching into Dallas County, which matters mainly when an adjuster asks.

One more thing worth saying out loud, because it shapes who calls us here. Roughly 42 percent of Lewisville’s housing is multifamily and the city is close to evenly divided between owners and renters, so a large share of these roofs belongs to a landlord, an investor or an HOA rather than to whoever is living underneath. We are glad to have either conversation, and we will tell either party the same thing about the roof.
