ES Windows Roofing: The Dallas Owner’s Guide
If you’re looking for an ES Windows roofing part in Dallas, we keep the common failure points on hand and can match most models same week. Installed replacement typically runs $400 – $1,800 depending on what let go, and the honest answer is that ES Windows parts aren’t carried by most big-box stores or generic roofing suppliers in Dallas anymore, so a company that actually knows the line saves you days of dead-end phone calls.
How owners usually find out: a drip starts near the window header after a hard north Texas storm, or the flashing pulls loose where the window meets the roof deck and you can spot daylight from inside. Sometimes it’s quieter than that, a musty smell in the wall cavity before you ever see water. By the time it’s visible, the part has usually been failing for a while.
Key Takeaways:
- ES Windows used matched flashing profiles that generic replacements don’t replicate cleanly.
- We stock the common ES Windows roofing parts on the truck for Dallas jobs.
- Written price before we touch anything, and a 365-Day Done Right Promise on every install.
Which ES Windows Models This Applies To
ES Windows produced several roofing and roof-window lines that show up in Dallas homes built between the late 1990s and roughly 2015. The parts most homeowners call about are the perimeter flashing kits for the ES Sloped and ES Vertical series units, plus the compression gaskets on the operable sashes. The compatibility gotcha nobody tells you: a flashing kit that fits a 2006 ES Vertical 48 will not seat correctly on a 2012 ES Vertical 48 because ES changed the outer frame profile by 4mm that year. Close enough isn’t close enough here. If you can’t read the glass etching or the data plate inside the frame, measure the visible glass width and the frame-to-frame dimension, and we can usually pin the series down from the numbers alone.
The OEM-versus-aftermarket call matters with ES Windows. OEM flashing is engineered for the exact frame profile and carries the original fit tolerance, but the lead time from the factory can test a homeowner in a Texas July. Quality aftermarket flashing can work if the fabricator has access to the actual extrusion profile data, not an off-the-shelf bend. We keep both options open, and we’ll tell you straight which one makes sense for the age of the unit and the condition of the roof deck around it. ES Windows also built exterior-integrated roof glazing for sunrooms and covered patios, and those call for a custom curb and cap assembly when the original curb rots. We’ve done that on homes near White Rock Lake where the original installers sealed the curb with something that gave up years ago.
Styles & brands we work with
Signs Your ES Windows Roofing Is Failing
- Water staining at the top inside corner of the window. This is nearly always flashing or gasket failure, not the glass itself. The sealant bead at the frame-to-roof junction dries and cracks in Dallas’s heat and UV, and water follows the gap in around the frame horns.
- Condensation that won’t wipe off between the glass panes. The insulated glazing unit’s edge seal has failed. It isn’t just a cosmetic thing: once that seal goes, the argon leaks out and the window loses its thermal performance. Condensation on the room-side surface is a humidity issue; between the panes means the unit is done.
- Flashing that pulls away from the shingles or roof membrane. Dallas’s freeze-thaw cycles and those spring hail storms work the metal loose from the deck. If you can flex the flashing by hand, water has a standing invitation.
- Soft drywall or staining in the ceiling below the window. This means water has already traveled down the framing and found the ceiling cavity. The window flashing failed weeks or months before you saw the mark.
- Operable sash that’s suddenly hard to open or close. The frame has flexed, usually from roof deck movement or failed flashing letting water soften the surrounding lumber. Forcing the sash just bends the hinge hardware, and hinge replacement on ES Windows roof units isn’t a cheap fix.

AfterReplacement Cost & What’s Included
In Dallas, you’re looking at $400 – $1,800 installed for the typical ES Windows roof window repair. The spread comes down to what failed. A compression gasket swap on a 48-inch unit might run $400 – $600. A full perimeter flashing replacement with roof deck repair runs $900 – $1,800 depending on how much of the surrounding decking has to come out and how far the water traveled. If the curb itself is rotted and we have to rebuild it, that’s a bigger job, and we’ll show you the number before anything gets pulled apart.
| Repair Type | Typical Installed Range in Dallas |
|---|---|
| Compression gasket replacement (per unit) | $400 – $600 |
| Flashing replacement, standard pitch | $800 – $1,400 |
| Flashing + roof deck repair | $1,200 – $1,800 |
| Full curb rebuild and re-flash | Quoted after site inspection |
Every one of those numbers is a written price before we start, not a range we’ll expand after demo. The price includes the part, labor, sealant, roof membrane repair where needed, and cleanup that leaves your place the way it should’ve been left the first time. And if the work fails inside a year under the 365-Day Done Right Promise, we come back and fix it at no charge. That’s in writing, not in the fine print of a handshake.
DIY or Call Us?
Fixing ES Windows roofing components isn’t a job we hand to a homeowner. The flashing sits at the point where the roof meets the window, and a bad seal there doesn’t fail quietly. The work demands a correct flashing profile, the right membrane underlayment, and often ladder work on a pitch where one wrong move sends you into a hospital. We’d rather see you spend your Saturday on something that doesn’t involve a roofing harness. What you can do safely is identify the part, check the model number, and help us understand the failure. That’s useful.
The honest view from the ladder: I’ve fixed neighborhood-advised “silicone fixes” that lasted two weeks and made the real repair twice as expensive, because silicone prevents the right sealant from bonding. Give us the details, and we’ll bring the part. Call (940) 204-5368 and Trevor or someone on the crew will tell you what to look for before we ever schedule a visit.
FAQs
The glazing unit itself can go 20 to 30 years, but the perimeter flashing and gaskets typically start showing real fatigue after 10 to 15 years of Dallas heat, hail, and freeze-thaw cycling. If your unit is approaching that age and you see staining or condensation between panes, you’re on the clock. Call (940) 204-5368 and we’ll give you a straight answer on what needs replacing now versus what can wait.
Sometimes, if the metal is still sound and the issue is a failed sealant bead, a clean re-seal buys you a couple of years. But if the flashing is dented from hail, lifting from the deck, or corroded at the corners, re-sealing is a waste of money. We’ll tell you which situation you’re in before we quote, and either way the estimate is free.
Most flashing and gasket replacements take one day from ladder to cleanup, assuming the roof deck under the flashing is in acceptable shape. If we find rot underneath, we’ll add the deck repair to the written scope and let you know how that changes the timeline. Call (940) 204-5368 for specifics on your unit.
We keep the common ES Windows perimeter flashing profiles and gasket sets on the truck for the series most common in Dallas. If your unit needs a part we don’t stock, we’ll tell you the lead time honestly before you commit to a dime. Call (940) 204-5368 and we’ll check availability while you’re on the phone.
Give you a number before I pick up a tool, that’s the only way I know how to start. If your ES Windows unit is leaking or you suspect the flashing is done, call (940) 204-5368 today and we’ll schedule a free estimate with a written price. We also stock and install parts compatible with KraftMaid, Cambria, and Silestone when the job calls for it. We serve Dallas and nearby areas, and we’ll leave your roof better than we found it.
