ECO Window Systems Roofing: The Dallas Owner’s Guide
If you have an ECO Window Systems skylight, roof window, or integrated flashing kit that’s leaking, cracked, or failing at the seal, we stock compatible replacement parts in Dallas and can typically have the work done in one visit. Installed pricing for ECO Window Systems roofing repairs in Dallas runs $400 – $1,800 depending on whether we’re replacing flashing, a pane, or the full curb assembly. Most owners discover the failure the same way: a water stain on the ceiling after a hard north Texas thunderstorm, or a skylight that fogs between the glass panes and won’t clear.
Which ECO Window Systems Models This Applies To
ECO Window Systems builds several roof window and skylight lines, and the parts are not all interchangeable. The fixed skylight units and the venting roof windows use different hinge assemblies, and the flashing kits are cut to match specific roof pitches – a flashing kit for a 3:12 pitch won’t seat right on a 6:12 Dallas roof. Before we order or pull a part, we check the identification label on the inside of the frame, which lists the model number, glass spec, and production date. If that label is faded or missing, we measure the visible glass and the curb dimensions to narrow it down. For ECO Window Systems specifically, we’ve found that aftermarket flashing kits from generic suppliers often sit 3 – 5mm proud of the original curb, which is enough to break the seal under Dallas heat cycling. OEM flashing or a supplier we’ve verified against the original spec is the safer call. We’re an independent service provider, not an ECO Window Systems dealer or affiliate, so we’ll tell you straight when OEM is the only sensible option and when a quality equivalent will hold up just as well.
Styles & brands we work with







Signs Your ECO Window Systems Roofing Is Failing
- Ceiling stain or drip below the skylight. Most of the time this isn’t the glass – it’s the flashing or the curb seal. Dallas gets intense UV exposure, and the rubber gasket between curb and frame dries out and cracks faster here than in cooler climates.
- Fog or moisture between the glass panes. The insulated glass unit has lost its seal. You can’t wipe this away; the condensation is inside the sealed space, and the pane needs replacement.
- Visible cracks in the outer pane. Hail does this. Even a small crack compromises the glass’s structural integrity and will spread with every temperature swing, which Dallas gets daily in spring and fall.
- Condensation on the interior frame in the morning. That’s usually a thermal bridge forming at the frame edge, which means the weatherstripping or the frame seal has degraded. Left alone, it leads to wood rot in the curb.
- Difficulty opening or closing a venting roof window. The crank mechanism and hinge arms on ECO units wear unevenly when the unit isn’t operated regularly. Forced operation tends to bend the arm, and then the window won’t seat flush when closed.

AfterReplacement Cost & What’s Included

For ECO Window Systems roofing work in Dallas, plan on $400 – $1,800 installed. A flashing replacement or single-pane swap lands at the lower end; a full curb rebuild with new insulated glass runs toward the top. Here’s the breakdown we give every homeowner before work starts:
- Flashing kit: $150 – $450 in parts, plus 2 – 4 hours of labor
- Insulated glass unit: $300 – $900 depending on size and coating
- Crank and hinge assembly for venting units: $120 – $350
- Curb rebuild (rot or structural damage): adds $500 – $900 in framing and sealing
You get a written price before we start – not a range, a number. The labor includes old-part removal, new-part installation, resealing, and cleanup. If the repair fails inside 365 days, we come back and fix it at no charge. That’s the Done Right Promise, and it’s on every invoice.
DIY or Call Us?
You can safely do two things before calling: check the interior frame for water trails that tell you where the leak enters, and photograph the ID label so we can pull the right part the first time. What we don’t recommend is climbing onto a Dallas roof to inspect or reseal flashing yourself. Roof pitch, heat-slicked shingles, and the tension involved in removing a mounted skylight make this a job for someone who does it regularly. We’ve also seen homeowners buy a “universal” flashing kit online, spend an afternoon fitting it, and then call us anyway when the first storm finds the gap. Give you a number before I pick up a tool – that’s the only way I know how to start. Call (940) 204-5368 and we’ll tell you what we think it needs and what it’ll cost.
FAQs

Most ECO Window Systems roof windows last 15 – 20 years in north Texas, though the gaskets and flashing typically need attention at the 10 – 12 year mark because our heat and hail age rubber faster than temperate climates. The glass itself can last decades if the seal holds. Call (940) 204-5368 and we’ll assess yours.
Yes, in most cases. If the glass is intact but the flashing or gasket failed, we repair just that component. If the insulated glass unit has fogged, the pane gets replaced, not the whole skylight. Full replacement only makes sense when the curb framing has rotted or the frame itself is bent from hail impact. We’ll give you a written quote either way.
Most flashing, gasket, and pane replacements take one visit of two to four hours. If we need to rebuild the curb, the job may take a second visit to allow the framing repairs to settle before we mount the unit. We’ll tell you the timeline before we schedule, and the price won’t change after we start.
We stock the most common ECO flashing kits, gaskets, and crank assemblies on our trucks and can order specific insulated glass units within three to five business days. For older or discontinued series, we source OEM parts through our supplier network or match a verified equivalent that meets the original spec. Call (940) 204-5368 with your model number and we’ll confirm availability on the spot.
