Lewisville sits in one of the more punishing exterior-durability zones in North Texas. The Lake Lewisville corridor and the I-35E/121 growth belt see a specific combination of stressors that don't line up neatly with generic "home maintenance" advice written for other parts of the country: violent spring hail events, straight-line wind gusts from squall lines rolling off the Metroplex, summer roof-deck temperatures that swing 60-plus degrees between a 100°F afternoon and a cooled night, and expansive clay soil that shrinks and swells with every wet-dry cycle. None of that is exotic to a Denton County homeowner — it's just the weather — but it means an exterior inspection here has to look for different failure patterns than the same checklist would in a coastal or northern climate.
Hail is the big one. Denton County sits inside a corridor that gets hit by significant hail almost every year, and Lewisville has taken direct hits in multiple recent storm seasons. Hail damage doesn't always look dramatic. A bruised shingle mat, a cracked window screen, or a dented gutter downspout can sit quietly for a year or two before it turns into a leak, and insurers care a great deal about when damage occurred and whether it was reported inside the claim window on your policy — which is usually one year in Texas. A twice-a-year self-inspection, done in spring before storm season and again in fall, gives you a documented baseline so you're not guessing whether last week's hail did anything or whether it's just cumulative wear.
The other regional factor that trips people up is foundation movement. Lewisville's soils are a mix of expansive clay and fill in many subdivisions, and North Texas doesn't get steady rainfall — it gets drought stretches followed by heavy rain. That cycle moves foundations more than most homeowners expect, and foundation movement shows up first at the exterior: siding that pulls away at a corner, brick that cracks in a stair-step pattern, or a door that suddenly binds. None of this is hurricane country and none of it is salt-air corrosion country, so skip any checklist that spends time on those things — what actually matters here is hail impact, wind-driven water intrusion, UV and thermal cycling on siding and trim, and soil-driven movement at the foundation line. This guide covers those five categories in the order most homeowners can realistically walk through in under an hour.
Not every failed item is an emergency, and treating all of them that way just leads to inspection fatigue. A reasonable way to triage: if water is actively getting into the house right now — a stain that's growing, a drip, a gap you can see daylight through — that's an active leak and it gets a tarp or temporary seal today, not next weekend. Everything else falls into two buckets: things to document and monitor, and things to get a professional opinion on before your next storm season.
For anything storm-related, photograph it the day you find it, with a date-stamped phone photo and, if you can, something in frame for scale (a coin or tape measure works fine). If a hailstorm or wind event happened recently and you're not sure whether the damage predates it, that documentation is what your insurance adjuster will actually want to see — memory and guesswork don't hold up nearly as well as a photo with a date. Keep a simple folder, digital or physical, and add to it every time you do this checklist, even when nothing looks wrong. A "nothing changed" entry is still useful if a dispute ever comes up about when damage occurred.
For foundation-related findings — new cracks, sticking doors, gaps at the slab — the right move is almost never to fix the cosmetic symptom (patching a crack, planing a door) without understanding the cause first. Foundation movement in expansive clay is often manageable with consistent watering and drainage correction, but sometimes it isn't, and you won't know which situation you're in without measurement over time. A foundation repair company that does soil-moisture and elevation monitoring is the right first call, not a general contractor.
Some things are genuinely fine to leave for your twice-a-year walkthrough, and some things shouldn't wait. Call a professional promptly if you see: multiple areas of granule loss or bare shingle mat on the roof, especially after a hail event; any active water intrusion or a ceiling stain that's spreading; horizontal foundation cracks or cracks wider than about a quarter inch; more than one or two doors or windows newly sticking at the same time; or storm damage to gutters, siding, or roofing that you suspect might be within your insurance claim window.
It's also worth getting a professional roof and siding inspection after any hailstorm large enough to make local news or dent your car, even if you can't see obvious damage from the ground — some hail bruising on shingles is genuinely hard to spot without walking the roof or checking it up close. Alpine Exteriors and other licensed local contractors can typically do that kind of storm-damage assessment quickly, and a written inspection report is useful documentation whether or not you end up filing a claim. If you do decide to file, most Texas homeowner policies have a one-year window from the date of loss, so don't let a "we'll get to it eventually" roof inspection turn into a missed claim.
One honest caveat: not every contractor who knocks on your door after a storm is working in your interest, and Denton County sees a wave of traveling storm-chase crews every spring. It's reasonable to ask for a local business address, verify Texas contractor licensing where applicable, and get a second opinion before signing anything, particularly for a full roof replacement. A legitimate local company, Alpine Exteriors included, should be comfortable with you getting a second inspection.
How often should I actually walk through this checklist?
Twice a year is a reasonable baseline — once in early spring before hail season ramps up, and once in fall after summer heat has had months to work on caulking, sealant, and roofing materials. Add an extra pass any time a significant hail or wind event hits your specific neighborhood, since storm cells in North Texas are often narrow enough that one side of Lewisville gets hit hard while another sees almost nothing.
Does minor hail damage really need to be fixed right away?
Not always. A few bruised shingles or a small ding in a downspout usually isn't an emergency by itself. The risk with hail damage specifically is that it's cumulative and it starts a clock on your insurance claim window, so the priority is documenting and getting it evaluated promptly, even if the actual repair can be scheduled for a more convenient time.
My house is only a few years old — do I still need to worry about foundation movement?
Yes, and sometimes newer construction is more exposed to it in the first several years, before soil around the slab has settled and landscaping has matured enough to regulate moisture. Denton County's clay content is high enough that even well-built newer homes can show early sticking doors or hairline cracks, particularly after their first serious drought-to-downpour cycle.
Can I do a full inspection myself, or do I need a professional every time?
The ground-level and attic checks in this guide are safe and reasonable for most homeowners to do themselves — you don't need to get on the roof. Getting on the roof itself, or making a final call on structural cracking, is where it's worth bringing in someone with the right equipment and experience, both for safety and because roof and foundation assessments genuinely benefit from seeing hundreds of similar houses in the same soil and climate conditions.
A self-inspection catches a lot, but it's not a substitute for someone who walks Denton County roofs and foundations every week and knows what normal wear looks like versus what a storm did. If your checklist turned up anything you're unsure about — or if it's just been a while since a professional has actually walked your roof — Alpine Exteriors serves Lewisville and the rest of Denton County alongside our work across Dallas, Fort Worth, Plano, Frisco, Arlington, Irving, and McKinney. Reach out for a straightforward exterior inspection, no pressure to sign anything on the spot, and a written summary you can keep in your own storm-documentation folder either way.
