ECO Window Systems Roofing: The West Covina Owner’s Guide
If you have an ECO Window Systems skylight, roof window, or integrated flashing system that has started leaking, sticking, or showing condensation between the glass, we stock the replacement parts and can typically install them within a day or two of your call. Installed costs for most ECO Window Systems roofing components in West Covina run $400 to $1,800 depending on the part and the extent of the flashing repair. Most owners discover the failure the same way: a small water stain on the ceiling drywall directly below the unit, or a drip that shows up only during the first heavy rain of the season.
The reality is that ECO Window Systems roof windows live in direct California sun, which ages seals and flashing at a different rate than the rest of the roof. West Covina’s dry heat and occasional pounding rain cycles mean the gaskets and flashing kits are almost always the first things to go, not the glass or the frame. We replace the failed part, not the whole unit, whenever possible.
Key Takeaways:
- We stock ECO Window Systems-compatible gaskets, operators, flashing kits, and hardware for most models.
- Installed replacement parts in West Covina typically run $400 to $1,800.
- We’re an independent service provider, not affiliated with ECO Window Systems, and we give you a written price before any work starts.
Which ECO Window Systems Models This Applies To
ECO Window Systems has produced several roof window and skylight lines over the years, and the good news is that many of the gaskets, hinge kits, and flashing components are shared across model families. The fixed skylight units, vented roof windows, and tubular sun tunnels each use different sealing systems, so the first step is identifying what you have. Look for the manufacturer’s label on the inside frame edge or on the operator arm. That label will show a model number and production year, and that information tells us exactly which gasket profile and flashing channel your unit needs.
One compatibility gotcha we see in West Covina regularly: the flashing kits are sized to the deck-mount versus curb-mount install. A deck-mount flashing kit will not seal correctly on a curb-mount installation, even if the window dimensions match. We always measure the rough opening and the curb height before ordering the replacement part. As for OEM versus aftermarket, ECO Window Systems gaskets are profile-specific, and a generic weatherstrip from a home center will not compress the same way. We install OEM-spec parts when available and use quality aftermarket equivalents only when they match the exact profile and material durometer. You should know what you’re getting before we ever pick up a tool.
Styles & brands we work with
Signs Your ECO Window Systems Roofing Is Failing
- Water staining on the ceiling or wall below the unit. This is almost always flashing or gasket failure where the roof window meets the shingle or tile. The water travels along the rafter and shows up several feet from the actual leak point, which is why a visual check of the unit often looks fine.
- Condensation trapped between the panes. This means the insulated glass seal has failed. The unit still keeps rain out, but it has lost its thermal performance and will not come back. The glass assembly gets replaced, not repaired.
- Stiff or binding operation on the vent crank. Dirt, oxidized lubricant, and UV-damaged nylon bushings inside the operator mechanism are the usual causes. A West Covina summer can cook the lubricant inside the operator arm until it turns to paste.
- Daylight visible around the closed sash. If you can see light through the weather seal while the window is locked, the gasket has compressed or cracked. The water path is already open, it just needs rain to confirm it.
- Flashing that pulls up or cracks at the corners. The metal flashing is thin, and thermal cycling flexes it at the corner bends. Once a corner tear starts, the leak will get worse with every storm season.

AfterReplacement Cost & What’s Included
For West Covina homeowners, here’s what we see on ECO Window Systems roofing parts and the installed work:
- Gasket or weather seal replacement: $400 to $800 installed, depending on unit size and access.
- Flashing kit replacement (deck-mount or curb-mount): $600 to $1,800 installed, including removal of the old flashing, inspection of the surrounding roof deck, and resealing the roof-to-curb connection.
- Operator crank or hinge replacement: $400 to $900 installed, including cleaning and re-lubricating the track.
- Insulated glass assembly replacement: $600 to $1,500 installed, depending on the glazing package and unit dimensions.
Every estimate includes the part, the labor, the cleanup, and a written price before work starts. We don’t give verbal ballparks that grow on the final bill. If we open the area up and find rotted decking under the flashing, we’ll stop and show you what we found before we touch anything else. The work itself is covered by our written guarantee for 365 days from the completion date.
DIY or Call Us?
There are things you can safely do from inside the house. Clean the track and the operator arm with a dry cloth. Check that the sash sits flush when closed. Look at the label and write down the model number so you have it when you call. If you can safely reach the roof from a stable ladder, you can use a hose to run water over the flashing corners while someone watches the ceiling inside. That tells you which corner is leaking, which saves everyone time.
What you should not do is pull the flashing or the unit and try to re-seal it yourself. Roof window flashing integrates with the shingles or tile around it, and a poorly resealed unit will leak worse than the one you started with. The roof around the unit is also where a misstep becomes a fall. We work on roof windows in West Covina year round and we’d rather come out and give you a straight answer than see someone patch it with hardware-store caulk and call it fixed. Call (707) 760-7579 and we’ll schedule a look.
FAQs
In West Covina’s climate, the glass and frame on a properly installed ECO Window Systems unit often last 20 to 25 years. The gaskets and flashing typically need attention around the 12 to 15 year mark, sometimes sooner if the unit faces direct afternoon sun every day of summer. Call (707) 760-7579 to have yours looked at before the rainy season.
Small corner tears can sometimes be patched with a compatible sealant as a short-term stopgap, but the repair rarely lasts more than a season or two because the metal keeps flexing at the same stress point. We quote the full flashing replacement, and we’ll tell you honestly if a patch is worth trying in your situation. A written estimate is free.
A gasket, operator, or hardware swap usually takes one to two hours. Flashing replacement or insulated glass replacement typically runs a half day, assuming the surrounding roof deck is sound. We’ll give you a clear time window before the crew arrives, and you’ll know the technician’s name and see their photo before they knock.
We keep the most common gaskets, operators, and flashing profiles for ECO Window Systems units stocked on our trucks. Odd sizes or unusual glazing packages may need to be ordered, which usually adds a few business days. We’ll tell you that upfront, in writing, before you commit to anything.
