Hail damage and windows: what Dallas homeowners should know

Dallas gets hit with hail more often than most people expect. The National Weather Service has the DFW metro in one of the most active hail corridors in the country, and the storms that roll through between March and June are not messing around. Baseball-size hail is not a once-in-a-generation thing here. It happened in Plano in 2024 and in North Dallas the year before that.

If you own a home in the DFW area, your windows will eventually take a hit. Here is what that looks like, what to do about it, and how to protect yourself going forward.

How hail actually damages windows

Hail does not just crack glass. It can damage windows in several ways that are not always obvious from inside the house:

Cracked or shattered glass

This is the one everyone notices. A large enough hailstone -- anything above about 1.5 inches in diameter -- can crack standard dual-pane glass on impact. Bigger stones shatter it outright. Single-pane windows and older annealed glass break more easily than modern tempered units.

The crack pattern tells you something. A starburst or bullseye pattern radiating from a single point is a classic hail impact. A long diagonal crack that runs corner to corner is more likely thermal stress or frame movement, which is not storm-related.

Failed seals

This one is sneaky. A hailstone can hit a dual-pane window hard enough to shock the hermetic seal around the edges without visibly cracking the glass. The seal fails, the argon gas inside leaks out, and within a few weeks or months you see fog between the panes. The window looks fine from the outside, but the insulating value is gone.

If your windows started fogging after a hailstorm, that is probably not coincidence. Document the timeline and include it in your insurance claim.

Frame and hardware damage

Vinyl and aluminum window frames can dent, crack, or deform from direct hail impacts. On vinyl windows, look for white stress marks or hairline cracks along the frame edges. On aluminum, look for dents and pitting. Damaged frames may not seal properly when the window is closed, leading to air and water leaks.

Also check the screen frames and hardware. Screens often take the worst of it because they are the outermost layer. Bent screen frames, torn mesh, and broken screen clips are all common after a DFW hailstorm.

Water intrusion

Cracked glass, failed seals, and damaged frames all let water in. In Dallas, the rain that follows a hailstorm can push water through compromised windows and into the wall cavity. Once moisture gets behind the drywall, you are looking at potential mold growth and rot in the rough opening framing. This is why temporary repairs matter -- even taping plastic over a broken pane buys you time.

What to check after a hailstorm

Walk every window in your house, inside and out, within a day of the storm:

Look at the glass from the outside for cracks, chips, and impact marks. Check at an angle with sunlight behind you -- small cracks are easy to miss head-on.

Look at the glass from inside for fogging or condensation between the panes. This may take a few days to appear, so check again a week later.

Run your hand along the frame edges and feel for dents, cracks, or rough spots that were not there before.

Open and close every window. If one suddenly sticks, does not latch, or has a gap when closed, the frame may have shifted from impact.

Check the screens. Even if the glass is fine, mangled screens need replacement and should be included in your claim.

Photograph everything. Date-stamped photos from the day after the storm are the single most useful piece of documentation in an insurance claim. See our [insurance claims guide](/guides/insurance-claim-window-damage-dallas) for the full process.

Repair vs. replace after hail damage

Not every hail-damaged window needs full replacement. Here is how we decide:

**Replace when:** The glass is cracked or shattered. The frame is dented, cracked, or warped. The seal has failed and the window is fogging. The window was already old or underperforming before the storm. In these cases, patching does not make sense -- you are better off getting a new unit that will perform correctly for the next 20+ years.

**Repair when:** Only the insulated glass unit (IGU) is damaged but the frame and hardware are in good shape. In this case, we can replace just the glass panel for about 40 to 60 percent of the cost of a full window replacement. The frame needs to be structurally sound and the sash dimensions need to match an available IGU -- but for newer windows (under 10 to 15 years old) this is often a good option.

**Replace the screen when:** The screen frame is bent, the mesh is torn, or the clips are broken. Screens are inexpensive and easy to replace, but they should be included in your insurance claim because the adjuster will count them.

Impact-rated windows: are they worth it in Dallas?

After going through one or two hailstorms, a lot of Dallas homeowners ask us about impact-rated windows. Here is the honest answer.

Impact-rated (also called impact-resistant) windows use laminated glass -- two layers of glass bonded to a plastic interlayer, similar to a car windshield. When a hailstone hits laminated glass, it may crack the outer layer, but the interlayer holds the pane together. No hole, no flying glass, no water intrusion.

Standard dual-pane tempered glass can withstand hail up to about 1 to 1.25 inches in diameter. Impact-rated glass is tested to withstand large missile impacts (a 9-pound 2x4 launched at 34 mph, per the Miami-Dade protocol) and will shrug off hailstones that would destroy a standard window.

The cost premium is real: impact windows run 30 to 50 percent more than standard windows of the same style. For a full-house project, that could be an extra $3,000 to $8,000.

Is it worth it? If your home faces west or northwest (the typical storm direction in Dallas), if you have had hail damage before, or if you are in a hail-prone area like Plano, Frisco, Allen, or McKinney -- it is a solid investment. You avoid the hassle and deductible cost of future claims, you get better noise reduction, and some insurance carriers offer a premium discount for impact-rated windows.

For homeowners on a tighter budget, a middle-ground approach works well: install impact glass on the west and north sides of the house (where storms hit first) and standard Low-E glass on the east and south sides. We do this split approach on a lot of DFW projects and it makes good financial sense.

Dallas neighborhoods and hail risk

Hail does not hit every part of Dallas equally. Based on recent storm patterns and claim data, these areas see the most frequent window damage:

**Plano, Allen, and McKinney** sit right in the corridor where supercell thunderstorms track through Collin County. The 2024 Plano hailstorm was one of the costliest single-event hail disasters in Texas history.

**North Dallas and Far North Dallas** (near the 635/75 interchange north to Addison and past) get clipped by storms that form over Denton County and track southeast.

**Richardson and Garland** catch storms that drop down from the north and northeast, especially in late spring.

**Preston Hollow, Lakewood, and East Dallas** are not immune. The 2019 tornado that tore through North Dallas touched these neighborhoods with hail and wind damage that is still being repaired on some homes.

**Frisco and Prosper** have seen increasingly frequent hail events as development has expanded north. New construction with builder-grade windows is particularly vulnerable.

No matter where you are in DFW, if you have lived here more than five years, you have probably been through at least one bad hailstorm. The question is whether your windows are ready for the next one.

What to do now

If your windows were damaged in a recent storm, call us at (945) 229-0300. We will inspect the damage, help you decide what needs replacement vs. repair, and walk you through the insurance claim process if you are filing one.

If your windows survived the last storm but you are thinking about upgrading to impact-rated glass before the next one hits, we can give you a free estimate that shows the cost difference and the long-term math. No pressure, no storm-chaser tactics -- just honest numbers from a crew that lives and works in Dallas and deals with this weather every year.
