ECO Window Systems Roofing: The Woodland Hills Owner’s Guide
ECO Window Systems roofing components, particularly the integrated flashing kits and seal assemblies that connect skylights to roofing membranes, typically cost $400 – $1,800 installed in Woodland Hills, depending on whether you need a seal replacement or full flashing replacement. Most owners discover the failure the hard way: a water stain on the ceiling, a drip during December rains, or visible cracking in the rubber gasket around the glass unit. We stock ECO Window Systems-compatible flashing, gaskets, and sealant on our trucks because these parts fail predictably in Southern California’s UV-heavy climate, and we can usually complete the swap the same day we diagnose it.
Here’s the thing about ECO Window Systems roofing components: when they fail, it’s rarely the glass. It’s the interface between the window or skylight and the roof itself. The sun bakes the rubber and silicone gaskets until they shrink, crack, and lose their seal. Then the first real rain finds every weak point. If you’re seeing water, you’re already past the “wait and see” stage.
Which ECO Window Systems Models This Applies To
ECO Window Systems manufactures a range of roof-adjacent window products, from fixed skylights to vented roof windows, and the compatible parts vary by series and glass thickness. The most common units we service in Woodland Hills are the standard residential skylight line with 1-inch insulated glass, which uses a specific gasket profile, and the vented units, which add a hinge and crank mechanism to the mix. Flashing kits are sold in two pitch ranges: low-slope (2:12 to 6:12) and steep-slope (6:12 to 20:12), and using the wrong pitch flashing is the single most common installation mistake we correct. A flashing kit designed for steep roofs will not lap correctly on a low-slope Woodland Hills ranch, and the seal will fail within a season or two.
To identify your unit, look for the serial plate on the interior frame or the etched logo on the lower corner of the glass. The plate will list the series number and glass dimensions. If the label has faded from sun exposure (common here), measure the visible glass width and length in inches, then check whether the unit is fixed or vented. With those two data points, we can confirm part compatibility before we arrive. OEM gaskets and flashing are still available for most ECO Window Systems models produced in the last 20 years; for older units, quality aftermarket equivalents from GAF’s accessory line perform identically and cost about 15% less. We’ll tell you which we’re using and why, every time.
Styles & brands we work with
Signs Your ECO Window Systems Roofing Is Failing
- Water stains on the ceiling or drywall around the skylight shaft. This means the flashing or gasket has already failed and water is traveling down the roof deck. The stain often appears weeks after the rain because water moves slowly through insulation before hitting drywall.
- Visible cracks in the rubber gasket around the glass. Southern California sun degrades EPDM rubber and silicone gaskets in roughly 8 – 12 years, faster if the unit faces west. Once you can see cracks from inside the house, the seal has lost most of its compression and is no longer watertight.
- Condensation between the two panes of glass. This means the insulated glass unit’s internal seal has failed. It’s not a roofing failure per se, but it signals the window assembly is aging, and the external gasket is likely near the end of its life too.
- Daylight visible through gaps around the flashing from the roof side. Flashing can lift over time as the roof membrane expands and contracts through summer heat and winter cool. If you’re on the roof and can see a gap between the flashing and the shingles, water is getting in.
- Rust streaks or pitting on metal flashing components. Coastal-adjacent moisture and winter rain cycles cause galvanic corrosion where dissimilar metals meet. Once the flashing corrodes through, replacement is the only fix.

AfterReplacement Cost & What’s Included
In Woodland Hills, the installed price for ECO Window Systems roofing work breaks down like this:
| Service | Price Range |
|---|---|
| Gasket replacement (fixed skylight, single unit) | $400 – $700 |
| Flashing replacement (standard roof slope) | $600 – $1,200 |
| Flashing replacement (steep slope or two-story access) | $1,000 – $1,800 |
| Full skylight replacement including flashing and gasket | $1,500 – $2,500 |
Every quote includes the parts, labor, roof access setup, and cleanup. What drives the range is access: a single-story ranch in Woodland Hills with a walkable pitch keeps costs at the low end. A two-story home with a steep tile roof pushes it higher because we need more time for safe staging and careful tile work around the flashing. The price we write down is the price you pay. No change orders, no “we found something unexpected” add-ons. If we find additional damage while the job is underway, we stop, show you what we found, and put the new scope in writing before continuing. And like every job we do, the work is covered by our written guarantee for 365 days from the completion date.
DIY or Call Us?
You can safely do the diagnostic part yourself: check the serial plate, measure the glass, look for visible cracks in the gasket from inside the house. You can also put a bucket under a drip and call us the next morning. What you should not do is get on a roof in Woodland Hills with a tube of silicone and try to re-seal a flashing assembly. Roof work on any pitch carries real fall risk, and a bad sealant job can trap water behind the flashing and accelerate rot in the roof deck. That turns a $600 gasket replacement into a $6,000 structural repair.
If you’ve confirmed the gasket or flashing is the problem, or even if you’re not sure, call us at (831) 290-6866 and we’ll come take a look. We’ll put the diagnosis and the price in writing before any work starts.
FAQs
In Woodland Hills, expect 8 – 12 years from the rubber gaskets and 15 – 20 years from metal flashing before UV exposure and temperature cycling cause failure. West-facing units degrade faster. If your skylight is past year ten, an inspection is worth scheduling. Call (831) 290-6866 and we’ll check it.
Small sealant failures can sometimes be patched to buy a season or two, but by the time water is visible inside your Woodland Hills home, the flashing is usually corroded or the gasket has lost compression. Patching a failed assembly is a temporary measure at best. Full replacement is the reliable fix.
Gasket replacement takes one to two hours. Flashing replacement takes three to four hours for standard access. Full skylight replacement with new flashing typically runs a half day. We’ll give you a time window before the job and the technician’s name and photo before they arrive.
We stock common gasket profiles, standard flashing kits in both pitch ranges, and compatible sealant from GAF and CertainTeed. If your unit needs a less common part, we order it and schedule the install within a few days. We also stock compatible parts for KraftMaid cabinetry, Cambria and Silestone surfaces, and GAF, CertainTeed, and Owens Corning roofing materials.
If your ECO Window Systems roofing component has failed, don’t wait for the next rain to confirm it. Call (831) 290-6866 today. We’ll identify the exact part, give you a written price before any work begins, and make sure the fix is done right the first time. Tell me what you need done. I’ll tell you what it takes and what it costs. Then we get to work.
