ECO Window Systems Roofing: The Long Beach Owner’s Guide
Roofing components built for ECO Window Systems skylight and roof-window frames typically run $400 – $1,800 installed in Long Beach, depending on whether you need a flashing kit, a replacement sash, or a full frame reseal. We keep common ECO Window Systems-compatible roofing parts on hand in our Long Beach shop and can usually get a technician to your home the same week. Most homeowners discover the problem after a rainstorm, when they notice a water spot spreading across the ceiling below the unit, or when a musty smell settles into the room and won’t leave.

Roofing parts fail differently than the window itself. The glass and frame can be fine while the flashing underneath quietly separates, or the curb starts to crack, and suddenly water has a path into the house. Because Long Beach gets salt air year-round and intense UV exposure through the summer months, the gaskets and sealants around roof penetrations age faster here than they do inland. Graham Stein and our crew have pulled apart enough of these units in neighborhoods like Belmont Shore and Bixby Knolls to know exactly where the weak points are on ECO Window Systems installations.
Which ECO Window Systems Models This Applies To

ECO Window Systems manufactures fixed skylights, venting skylights, and roof windows in a range of deck-mount and curb-mount configurations. The roofing components we replace fall into three groups: the perimeter flashing kits, the curb assemblies that elevate the unit off the roof deck, and the gasket seals between the glass sash and the frame. Your specific model number is printed on a sticker inside the frame, visible when you open the vent or remove the interior trim ring. Take a picture of it before you call us. It saves a trip and helps us bring the right part on the first visit.
One compatibility gotcha we see regularly in Long Beach: ECO Window Systems flashing kits are matched to specific roof profiles. A flashing kit listed for a standard composition shingle roof will not seal correctly on a Spanish tile roof in Naples or a low-slope modified bitumen roof near the coast. We measure the roof pitch and the existing curb dimensions on site before recommending a replacement. When an OEM ECO Window Systems part is backordered or discontinued, we offer quality aftermarket equivalents from manufacturers we have tested on local installations. We tell you which one we’re using and why, and the price reflects the difference, not a markup for ambiguity. This is an independent Elmstead Remodeling Long Beach service. We are not affiliated with ECO Window Systems, but we have installed and repaired their products across Long Beach for years.

Signs Your ECO Window Systems Roofing Is Failing
- Water staining around the interior drywall. This tells us the flashing or curb seal has separated and water is traveling along the frame. The stain may appear inches from the unit because water follows the rafter before it drips.
- Condensation between the glass panes. The seal around the sash has failed, not the roof flashing, but both need attention. A fogged unit will not dry out on its own and the thermal performance is gone.
- Daylight visible through the frame corner. Open the vent and look where the sash meets the frame. If you see a sliver of sky, the gasket has compressed or torn, and the next rain will find it.
- Musty smell that gets worse after rain. Moisture has been getting in long enough to soak insulation or the ceiling cavity. This is the point where a small flashing repair becomes a bigger drywall and insulation job if it is ignored.
- Granules from the shingles collecting in the gutter directly below the unit. This points to water running under the shingles near the flashing, lifting them, and sending mineral granules down the roof slope. It is a sign the seal was compromised some time ago.

AfterReplacement Cost & What’s Included

Expect to pay $400 – $1,800 in Long Beach for installed roofing components on an ECO Window Systems unit. The low end covers a straightforward flashing kit replacement on a standard composition shingle roof with no curb damage. The high end reflects a full curb rebuild plus new flashing on a tile or low-slope roof where we remove and re-bed tiles. Skylight replacement, if the sash itself is gone, falls under our window replacement pricing at $4,500 – $15,000, but roofing-specific work on the ECO unit almost always lands in that $400 – $1,800 range.
Every quote is written, with the part number, the labor, the sealant product we plan to use, and the full price before any work starts. That written number does not change once our crew arrives. If we open the roof and find rot in the curb that was not visible from the outside, we stop, show you what we found, and write a new number before touching anything else. No surprises on the invoice. The 365-Day Done Right Promise covers the completed repair. If the flashing leaks or the seal fails within a year of our work, we come back and make it right.
DIY or Call Us?
There are things worth doing yourself, and there are things that require a ladder, a roofing membrane, and the judgment to know when a curb is rotted beneath the surface. Working on a roof in Long Beach with marine air and morning condensation makes surfaces slick, and a damaged curb can look fine from the outside while the structural wood underneath is soft. Falling through a skylight curb is a real injury risk. We recommend owners do no more than clear debris from around the unit and photograph the model label. Leave the flashing, the sealant, and the curb work to a trained professional with fall protection and the right sealants for coastal conditions.
Safety on a roof is not about being cautious at the edge. It is about knowing what the deck feels like underfoot before you commit your weight. That takes experience. Call us at (562) 512-7086 and we will send a background-checked, uniformed technician to look at it. The estimate is free.
FAQs

Flashing kits and curb assemblies typically last 12 – 20 years in Long Beach, but the gasket seals around the sash often need replacement in year 8 – 12 because salt air and UV exposure shorten their lifespan. Coastal homes in Naples or Belmont Shore tend to need seal service sooner than homes further inland. Call us at (562) 512-7086 if your unit is in that age range and you want a condition check. It is free to have us look.
Sometimes, yes. If the separation is limited to one corner and the metal is intact, a proper cleaning and a marine-grade sealant can buy you a few years. If the flashing has lifted along more than one edge or the curb shows signs of rot, a full replacement is the honest answer. We will show you the condition before we give you a price, and that price is written down before the work begins.
Most flashing and curb replacements on ECO Window Systems units in Long Beach are completed in four to six hours, including cleanup and a photo of the finished work. If we need to re-bed tiles or replace decking beneath the curb, plan for a full day. Your written quote includes the time estimate, and we respect that schedule.
We stock common flashing kits, curb assemblies, and sash gaskets for ECO Window Systems units in our Long Beach shop, along with quality aftermarket equivalents for discontinued OEM parts. When we need to order a specific part, we give you the timeline before any work is scheduled. Like the cabinets from KraftMaid and the countertop materials from Cambria and Silestone we use in other projects, we only install parts we can name and stand behind.
Free Estimate: Call (562) 512-7086. A live person answers, 24/7, and we will schedule a technician to inspect your ECO Window Systems roofing in Long Beach. The price we write down on day one is the price on the invoice when we’re done.
