ECO Window Systems Roofing: The Los Angeles Owner’s Guide
We stock and install ECO Window Systems-compatible roofing parts across Los Angeles, with most replacements running $470 to $2,125 installed depending on the part, roof pitch, and accessibility. If you’re reading this, you’ve probably spotted water staining on a ceiling, felt a draft near a skylight flashing, or noticed granules collecting in your gutter after every rain. Most ECO Window Systems owners don’t discover a failed roofing component until water has already found its way into the sheathing, so let’s get you matched to the right part and on the schedule.
Penhallow Remodeling is an independent service provider. We’re not affiliated with ECO Window Systems, but we’ve worked on enough of their installations across the Valley, Westside, and South Bay to know exactly which components fail first and what it takes to make them right. If your ECO Window Systems skylight, roof window, or integrated flashing system is leaking or showing wear, call us at (936) 259-2607 and we’ll walk you through what you’re looking at before you spend a dollar.
Key Takeaways
- Typical ECO Window Systems roofing repair in Los Angeles: $470 – $2,125 installed.
- The failure is often the flashing, not the window unit itself, which changes the repair cost significantly.
- We carry common ECO Window Systems flashing kits and sealants on the truck for same-visit fixes.
- Every repair comes with our written 365-Day Done Right Promise. If it fails, we return at no charge.
Which ECO Window Systems Models This Applies To
ECO Window Systems manufactures a range of roof windows, skylights, and integrated glass roof panels, and the compatible part depends heavily on which series you have. The most common installations we see in Los Angeles homes fall into three groups: fixed skylight units, venting roof windows with manual or electric operators, and their proprietary curb-mounted flashing kits designed to tie the unit into composition shingle or tile roofs.
The quickest way to identify your unit is to look for the product label etched into the glass corner or printed on the frame’s interior edge. It will list a model number and series code. That matters because the flashing profile is not universal across their line. A flashing kit sized for their older curb-mount series will not seat properly on the deck-mount units they started shipping more heavily after 2015, and forcing it creates exactly the kind of seam failure that brings water into your attic. If you can’t find the label, measure the rough opening and the exterior curb height and call us. We’ll identify the unit over the phone in most cases.
For OEM versus aftermarket: ECO Window Systems’ own flashing and gasket kits are the safest path when they’re still available, particularly for units still under the manufacturer’s coverage period. For older discontinued series, we use a quality aftermarket flashing system with a self-sealing collar and heavy-gauge aluminum that holds up to Los Angeles’s UV exposure. Either way, we give you a written price before ordering anything so there’s no surprise on invoice day.
Signs Your ECO Window Systems Roofing Is Failing
- Water staining on the ceiling or wall below the unit. This is the one we hear about most. The stain is nearly always the result of a flashing seam that’s separated, not a cracked pane. Water travels along the top chord and pools near the drywall, which is why the stain is sometimes several feet from the window itself.
- Condensation between the glass panes. ECO Window Systems units are sealed with an insulating gas fill. Once the perimeter seal fails, that gas escapes and you get interior fogging that won’t wipe off. The window still functions, but the thermal performance is gone and the seal will only get worse.
- Draft or temperature change directly under the skylight. A failed gasket around the sash or frame lets conditioned air escape. In Los Angeles summers, you’ll feel heat radiating down through the opening. It means the operable unit isn’t closing tightly or the fixed unit’s perimeter seal has degraded.
- Granules from your shingles collecting in gutters near the unit. Not always a window problem, but if the granule loss is concentrated around the skylight or roof window, it’s a sign the flashing has been channeling water into the shingle course below and accelerating wear. The window likely needs reflashing before the shingle damage spreads.
- Visible rust or cracked sealant around the exterior curb. Older flashing kits use galvanized steel which eventually corrodes, especially within a few miles of the coast. Once the metal is compromised, the sealant bead can’t hold and water gets underneath during our winter rain events.
Replacement Cost & What’s Included
For ECO Window Systems roofing work in Los Angeles, plan on $470 to $2,125 installed. The bottom of that range covers a straightforward gasket replacement, re-sealing, or minor flashing repair on a single low-pitch roof. The top end reflects a full flashing system replacement or an operable roof window swap on a steep tile roof that requires additional safety setup and tile cutting.
What drives the number is mostly roof access and the condition of the surrounding shingles or tile. A one-story home with a gentle composition roof and easy ladder access stays on the low side. A two-story home in the Hollywood Hills with clay tile and a 45-degree pitch requires scaffolding, tile removal, and more labor hours, so the price moves accordingly. Every quote we give includes the part, labor, disposal, and our written workmanship warranty. No change orders mid-job, no surprise line items.
| Repair Type | Typical Installed Price (Los Angeles) |
|---|---|
| Seal / gasket replacement | $470 – $825 |
| Flashing repair or partial re-flash | $590 – $1,180 |
| Full flashing system replacement | $1,180 – $2,125 |
| Roof window / skylight unit replacement | $1,770 – $3,540+ |
The unit replacement number above is for the roofing component work. If you’re replacing the entire skylight unit including new interior trim and drywall, that crosses into window replacement territory and we’ll scope it separately. As with all our work, the written price comes before you commit, and the 365-Day Done Right Promise covers the repair in writing. We come back free if it fails within the year.
DIY or Call Us?
There are a few things you can safely do before calling us. Check the interior frame for moisture, look for visible light gaps around the sash, and snap clear photos of the exterior flashing from the ground or a ladder you’re comfortable on. That helps us quote the job faster.
What you shouldn’t do is climb onto a roof with a caulk gun. Roofing work on any pitch carries real fall risk, and the flashings around skylights are under tension from thermal cycling. If you mis-seat the flashing or use the wrong sealant, you’ll get the same leak plus a false sense that it’s fixed, and the water damage keeps compounding behind the drywall. This is one of those jobs where the repair costs less than the hospital visit or the future mold remediation. If you’re not sure whether you have a real problem, call (936) 259-2607 and describe what you’re seeing. If it’s simple, we’ll tell you so and you won’t owe us anything for the phone call.
FAQs
Most ECO Window Systems flashings last 12 to 20 years in Los Angeles conditions, though homes within a few miles of the coast often see the galvanized components corrode in 10 to 12 years due to salt air. Our UV exposure also hardens sealant beads faster than in cooler climates, so inspecting the flashing every five years is a smart habit. Call (936) 259-2607 and we’ll take a look during a broader roof assessment if you’re already having work done.
A leaking skylight can usually be repaired, often with a re-flash and new sealant rather than a full unit replacement. The window itself typically only needs replacing if the glass seal has failed, the frame is warped, or the operator mechanism on a venting unit is broken. We’ll always price the repair option first and tell you honestly when replacement is the better long-term value.
Most flashing replacements on a standard composition roof take a half day to a full day, including removing the old flashing, setting the new kit, re-sealing, and cleaning the site. Tile roofs add time because we remove and reset the surrounding tile course carefully. We’ll give you a defined arrival window before work starts, and you’ll know the total time commitment before we begin.
We keep common ECO Window Systems flashing kits, gaskets, and sealants on the truck for the most frequently installed series in Los Angeles. For older or discontinued models, we source the part from our local supplier network, usually within two to three business days. We’ll verify the part is correct and give you a written price before any order is placed.
If your ECO Window Systems roof window or skylight is showing any of the signs above, call us at (936) 259-2607. We’ll help you identify the part, give you a written price, and schedule the repair on a real arrival window. Give me the whole picture first, then we pick up the tools.
