ES Windows Roofing: The Dallas Owner’s Guide

If you’ve got an ES Windows roof assembly that’s failing, you’re probably looking at installed replacement costs between $400 and $1,800 in Dallas, depending on whether we’re swapping a single flashing component or rebuilding the full roofing system around your ES Windows unit. We stock ES Windows-compatible roofing parts on our trucks, and we can usually get your replacement scheduled within a few days once we confirm the exact model. Most Dallas homeowners discover the problem the same way: a water stain on the ceiling after a hard rain, a visible gap where roofing meets the window frame, or deteriorated sealant you can spot from the ground with a pair of binoculars.

You should know who is coming, what it costs, and what happens if something goes wrong, before we ever pick up a tool.

Which ES Windows Models This Applies To

ES Windows manufactures impact-rated aluminum window and door systems commonly paired with integrated roofing assemblies on modern Dallas homes, particularly in newer construction where window walls meet rooflines directly. The roofing components we handle include the head flashing, sill flashing, jamb flashing, and the integrated drainage channels that sit above and below the window unit itself. If you’ve got an ES Windows sliding glass door or a fixed window assembly that ties into a flat or low-slope roof, that junction is where most failures start. Look for a small metal tag or sticker on the interior frame: ES Windows stamps their units with a serial number and model designation on the top or side jamb. That number tells us the series, the year of manufacture, and what flashing profile was originally specced. Measure the rough opening width in inches, and note whether your roof pitch is flat, low-slope, or standard shingle; ES Windows pairs different flashing kits depending on the roof angle. We’re an independent service provider, not affiliated with ES Windows directly, which means we stock both OEM parts and quality aftermarket equivalents, and we’ll tell you honestly when the aftermarket version is actually better. Some of the original ES Windows flashing extrusions use a proprietary alloy that’s hard to source, so we keep a running inventory of the common profiles and fabricate what we can’t buy.

Signs Your ES Windows Roofing Is Failing

  • Water staining on the ceiling or wall directly below the window. Dallas gets intense, wind-driven rain in spring and fall, and the junction where an ES Windows unit meets roofing is the most common entry point. If the stain appears after a storm with high winds, not just heavy rain, the flashing has likely lifted or separated.
  • Visible gaps or lifted edges in the metal flashing above the window. Texas heat cycling expands and contracts aluminum, and after enough 100-degree summers, factory sealant dries and cracks. You’ll see daylight through a gap that should be closed, or a piece of flashing that’s bowed outward.
  • Crumbling or missing sealant beads around the window-roof junction. ES Windows factory installations use a specific elastomeric sealant. When it fails, it looks chalky, cracked, or peeled back from the metal. Recaulking alone won’t fix this once water has gotten underneath; the flashing itself needs to be pulled and reset.
  • Condensation between the glass panes. This one fools a lot of Dallas owners into thinking the window itself is bad, when the real issue is that roof drainage has been dumping water onto the top of the frame. Persistent moisture works into the glazing seal, and suddenly you’ve got fog you can’t wipe off.
  • A rust line or drip stain running down from the top of the window frame. This tells us the galvanized or aluminum flashing has been compromised long enough that the frame itself is now weeping. By the time you see this, water has been moving through the assembly for at least a season, and the repair usually involves more than a simple part swap.

Replacement Cost & What’s Included

In Dallas, ES Windows roofing repair runs $400 to $1,800 installed, with the spread driven by access, roof pitch, and how much surrounding roofing material we have to remove to get to the flashing. A single-piece head flashing replacement on a one-story with a standard shingle roof usually lands at the low end. A full junction rebuild on a two-story with a flat roof, custom-fabricated flashings, and new underlayment pushes toward the high end. Here’s how it breaks down:

  • Flashing component replacement (single piece): $400 – $800
  • Full ES Windows roofing junction rebuild (flashing, underlayment, sealant, re-roofing the tie-in): $900 – $1,800

Every job includes the parts, labor, disposal of the old materials, and our walk-through afterward. You get a written price before we start. It’s not a ballpark number we whisper at you; it’s the price. And our 365-Day Done Right Promise covers the work. If the junction fails within a year of completion, we come back and fix it at no cost to you. Isaac Pruett walks every job himself before the first tool goes up, because flashing that looks fine on a drawing can be hiding a problem you only see standing on the roof looking down.

DIY or Call Us?

You can safely do one thing: look. Stand back with binoculars or get out a drone if you have one, and check whether the flashing is lifted, the sealant is cracked, or there’s visible rust. Taking a few phone photos before you call helps us quote faster. What you shouldn’t do is climb onto the roof yourself, especially a low-slope or flat roof where the ES Windows junction sits in a valley or right at the edge. Falls are the most common way Dallas homeowners end up in the ER over a roofing issue, and working on flashing while leaning over a roofline is not a weekend project. A wrong fix here, like slapping roof cement over a lifted flashing, traps water behind it and turns a $600 job into a $1,500 one. If you’re not sure what you’re looking at, call (432) 302-8761 and describe what you see. We’ll tell you whether it warrants a service visit, and the estimate is free either way.
