ECO Window Systems Roofing: The Houston Owner’s Guide
If you have an ECO Window Systems roof window or skylight that’s leaking, cracked, or fogged between the glass, we stock the replacement glazing, flashings, and hardware to match it, and a full swap typically runs $600 – $2,500 installed in Houston depending on size and access. Most owners discover the failure after a heavy Gulf Coast rain, when a brown stain appears on the ceiling or water beads up on the windowsill, or they notice the glass has gone milky and won’t clear. You don’t need to replace the whole roof opening. You need the right part matched to your unit, and that’s a job we handle regularly.
We’re an independent Houston contractor, not affiliated with ECO Window Systems, but we source factory-spec and quality aftermarket components for their roof window lines and install them to hold up under Houston’s heat, humidity, and storm cycles.
Which ECO Window Systems Models This Applies To

ECO Window Systems roof windows are found most often on flat and low-slope roofs across Houston, from Meyerland ranches to newer builds in Katy and The Woodlands. The three things that matter for parts matching are the rough opening size, the glazing type, and the flashing kit profile. The size is stamped on the aluminum frame or on a label under the sash; common ECO window sizes run from 2×2 feet up to 4×4 feet, but we’ve matched units outside that range too.
One gotcha Houston owners run into: ECO’s curb-mounted and deck-mounted units take different flashings, and a deck flashing will not seal a curb-mounted window no matter how much sealant you apply. We see that mismatch fairly often after a previous repair. For the glazing itself, factory OEM is the safest match for warranty continuity, but for older units where the original glass is discontinued, we can source a high-quality aftermarket insulated glass unit with the same overall thickness and a low-E coating that actually handles Houston’s UV load better than the original on some older models.
Styles & brands we work with







Signs Your ECO Window Systems Roofing Is Failing
- Water staining on the ceiling or drywall around the opening. This usually means the flashing has pulled away from the roof membrane or the seal around the curb has cracked. In Houston’s heat, roofing sealants dry out and separate faster than in cooler climates, which is why we re-bed with high-temp rated sealant on every job.
- Condensation or fog between the panes. The insulated glass unit has lost its seal. Once the desiccant inside is saturated, the fog won’t clear on its own. The fix is a replacement glazing unit, not a repair.
- Visible cracks in the glass or frame. A hailstorm or a falling branch is the usual culprit. Even a hairline crack in the outer pane will let moisture into the air gap. The unit needs replacing before the next downpour.
- The sash won’t open, close, or lock. The operator mechanism or hinge has worn out, or the frame has shifted slightly as the Houston clay soil beneath the house moves. We can replace the hardware and re-align the sash without replacing the whole window.
- Drafts or a visible gap around the unit on a windy day. The installation was never fully sealed, or the foam backer rod has degraded. It’s a slow leak waiting to become a fast one.
Replacement Cost & What’s Included

For ECO Window Systems roof window parts in Houston, glazing replacement alone runs $600 – $1,400 for most standard sizes. A full unit swap with new flashing and re-sealing runs $1,500 – $2,500 installed, depending on whether it’s a curb mount or deck mount and how much of the surrounding roof membrane has to be lifted and re-sealed. If we’re pulling up roof material around the opening, the roof deck condition also factors in. Rotten sheathing is a separate fix, and we will show you exactly what we found before adding any work.
Every quote is written, line by line, parts and labor separated. The number we give you before work starts is the number on the invoice. That’s the Kingswell standard, and it applies to every roof window job we do in Houston, no exceptions.

You can safely check the model tag, measure the glass dimensions, and clear debris from the roof opening. What you should not do is get onto a Houston roof in July to unseal and re-set a roof window. The decking is hot, the slope is unforgiving, and a broken seal done halfway is a roof leak you won’t find until the next storm. We have the tools, the right flashing profiles, and the high-temp sealants this climate demands, and every technician shows up background-checked and in uniform.
If you know the part has failed, give us a call at (254) 527-5340. We’ll ask for the rough opening size and what you’re seeing, and we’ll give you a straight answer on what it costs before we ever set foot on the roof.
FAQs

A properly installed unit with intact flashing should give you 15 – 20 years in Houston, but the sealants around the flashing often need re-bedding at the 8 – 10 year mark because our summers bake them hard. The glazing unit itself can last longer, but once the perimeter seal starts wicking moisture or the roofing around the curb lifts, the clock moves fast. Call (254) 527-5340 and we’ll tell you honestly whether you need a re-seal or a full unit swap.
A fogged insulated glass unit cannot be economically repaired in place; once the seal has broken, the glass needs to be removed and the unit replaced. We stock replacement glazing for common ECO Window Systems sizes and can order odd sizes without sending you through a distributor. Estimates are free, and the price is written before any work starts.
A glazing-only swap takes one to two hours on site. A full unit replacement with new flashing and roof re-sealing usually takes a half day. If Houston weather forces a delay, we’ll tell you exactly when we’re coming back, and a real person answers our phone 24/7 if you need to check.
Our Houston crews carry the standard flashings, sealants, and glazing tape for common ECO Window Systems roof window sizes, plus replacement glazing for the sizes we see most often. If your unit needs an odd-size part, we order it and schedule the install the day it arrives. We also keep components for KraftMaid cabinet hardware, Cambria countertop repairs, and Silestone service work, so if you have multiple house projects, one call handles it.
