ES Windows Roofing: The Orlando Owner’s Guide
We stock and install ES Windows-compatible roofing components across Orlando, with most installed jobs landing between $600 and $2,500 depending on the failure and the series you’re running. Most owners find us the same way: a Florida afternoon storm rolls through, water starts streaking down an interior wall near a picture window, and suddenly that “maintenance-free” ES Windows skylight or roof-integrated glazing unit isn’t so maintenance-free. We carry the common replacement gaskets, flashing kits, and glazing panels on our trucks, so if your part failed the way most do, we can usually get it addressed the first visit.
Key Takeaways
- ES Windows roof-integrated units fail most often at the gasket and flashing lines, not the glass itself.
- Installed replacement work in Orlando runs $600 to $2,500, with most jobs under $1,800.
- We’re an independent installer, not an ES Windows dealer, so we’re free to use the part that fits your unit best rather than whatever one brand pushes.
Which ES Windows Models This Applies To
ES Windows builds roof-integrated glazing across three general lines: fixed skylight units, operable venting skylights, and structural glass roof panels used in sunrooms and covered patios. The fitting challenge is that ES Windows has used at least three different gasket profiles since the early 2000s, and the profile is not stamped on the frame the way it is with some European manufacturers. You’ll need to measure the gasket channel width (usually 4mm, 6mm, or 8mm) or bring us a small section of the old gasket. We match by that measurement plus the frame edge profile, not by the model name alone.
On the parts themselves, there’s a real OEM-versus-aftermarket conversation. ES Windows-branded gaskets and flashing kits carry a premium, and in our experience the aftermarket EPDM gaskets from US suppliers hold up at least as well in Orlando humidity. We’ll quote both options when both exist. For glass roof panels, we always go OEM or a verified structural equivalent because the tolerance on load-bearing glazing is not something you gamble with.

Signs Your ES Windows Roofing Is Failing
- Water staining on the ceiling below the unit. This is the classic first sign. It almost always means the gasket has compressed or the flashing seal has pulled away from the roof membrane. By the time you see the stain, water has been traveling along the frame for weeks.
- Condensation between the glass panes. That means the sealed glazing unit has lost its inert gas fill. The glass itself is fine, but the thermal performance is gone. Here in Orlando, that means heat gain and humidity problems, not just aesthetics.
- Visible cracking or flattening of the rubber gasket around the frame. Florida sun bakes EPDM. Once the gasket loses its rebound, it stops sealing. You’ll see hairline cracks that widen under finger pressure.
- The unit won’t open or close smoothly, or the crank spins without engaging. This is a mechanical failure in the operator mechanism, not a seal problem. ES Windows venting units use a geared operator that can strip over time, especially if debris from nearby oak trees sits in the track.
- Drafts or whistling through the frame during storms. The gasket has failed enough to allow air movement. It’s not just noise; it’s the first path for wind-driven rain.

AfterReplacement Cost & What’s Included
In Orlando, ES Windows roofing replacement work breaks down roughly like this:
| Service | Typical Installed Cost |
|---|---|
| Gasket replacement (single skylight) | $600 – $1,200 |
| Flashing repair or replacement | $800 – $1,800 |
| Glazing unit replacement (sealed glass panel) | $1,500 – $2,500 |
| Full unit replacement (fixed skylight, mid-size) | $1,200 – $2,500 |
The variance comes down to access. A single-story roof with a 4/12 pitch is a quick job. A second-story unit with a 6/12 pitch and tile roofing around it takes longer, plain and simple. Every quote includes the part, the labor, the roof membrane patching if required, and cleanup. The written price you approve is the price on the invoice, no change orders mid-job. That’s The Relay Standard we’ve run under since 2005. And every repair carries our 365-Day Done Right Promise: if the repair fails inside a year, we return and make it right, backed in writing, no argument.
DIY or Call Us?
There are two things an owner can safely check: first, whether the weep holes in the frame are clogged with Central Florida pollen and leaf litter (clear them with a toothpick), and second, whether the fasteners holding the interior trim ring are loose (a snug-but-not-tight re-torque with a hand screwdriver will sometimes stop a minor interior condensation path). What you should not do is get on a roof with a caulk gun and start fixing flashing. The pitch, the heat, and the unpredictability of a failing roof edge make that a job for someone with roofing experience and the right fall protection. Silicone over failing flashing is a band-aid that buys you a few months and makes the eventual proper repair take longer. If you see water or seal failure, call us at (850) 809-0306. We’ll get eyes on it, quote it in writing, and you can pay from a link when the job is done.
FAQs
In Orlando’s UV and humidity, ES Windows gaskets typically need replacement every 8 to 12 years, while the glazing units and frames themselves can last 20 to 30 years with proper gasket maintenance. The unit isn’t the problem; the rubber around it is. Call (850) 809-0306 if your gaskets are showing cracks, and we’ll get you a free estimate.
Gaskets can sometimes be spot-patched with the right EPDM splice product, but in our experience a spliced gasket in full Orlando sun gives you maybe another year before it fails elsewhere on the frame. For flashing failures, replacement is the only repair that holds. We’ll tell you straight if a repair will hold or if you’re better off replacing the part now. Call (850) 809-0306 to discuss your specific unit.
Most gasket and flashing jobs are done in a single visit of three to five hours, including roof cleanup. Glazing unit replacements are usually scheduled in two trips: one to measure and order the panel, a second to install, with the install taking half a day. Call (850) 809-0306 and we’ll give you a realistic timeline for your situation.
We carry common gasket profiles and flashing kits on our trucks, and for the glazing panels we use a local Orlando glass fabricator who can turn a sealed unit in three to five business days. We’re an independent installer, not an ES Windows dealer, so we source whatever fits your unit correctly. Call (850) 809-0306 to check availability for your model.
