ECO Window Systems Roofing: The Fort Lauderdale Owner’s Guide
We stock and install ECO Window Systems-compatible roofing components in Fort Lauderdale, with typical roof repairs running $400-$1,800 and full replacements at $8,000-$20,000 depending on square footage and decking condition. Most ECO Window Systems parts we carry are available same-day from our Fort Lauderdale warehouse, and we quote every job in writing before any work starts. Homeowners usually discover the problem after a hard rain: water staining the ceiling near a window-to-roof transition, or a draft they can’t trace to the sash - the flashing detail where ECO Window Systems windows meet the roofing plane has separated or the membrane has cracked under South Florida UV.
Which ECO Window Systems Models This Applies To
ECO Window Systems produces several product lines common in Fort Lauderdale homes built between 2005 and 2020, and the roofing interface parts vary by series. The Impact Plus and Classic Series windows use a 2-inch nailing flange with an integrated drip cap, while the Architect Series carries a 3-inch flange and a separate aluminum head flashing. Check the etched code in the glass corner or the sticker on the frame edge - the first three digits tell us which flashing profile and membrane width you need.
We source OEM ECO Window Systems flashing kits when they’re available, but we’ve also vetted aftermarket equivalents from MFM Building Products and Grace that meet Miami-Dade wind uplift standards and carry comparable 10-year material warranties. The aftermarket route typically saves 15-20% on parts without sacrificing performance, and we list both options in our written quote so you can choose. One compatibility gotcha: the Architect Series head flashing looks identical to a generic 3-inch profile but has a slightly deeper receiver groove; forcing a standard piece causes a bow that voids the seal within two rainy seasons.
Signs Your ECO Window Systems Roofing Is Failing

- Water stains on interior drywall below or beside the window. This usually means the head flashing has lifted or the membrane has lost adhesion at the roof-to-wall transition. In Fort Lauderdale’s salt-air environment, the butyl sealant ECO Window Systems used on pre-2015 installs tends to harden and crack after 8-12 years.
- Visible gaps or daylight between the window frame and siding/stucco. The sill pan or jamb flashing has shifted, often from thermal cycling in our summer heat. Water follows the path of least resistance and pools behind the exterior finish.
- Musty odor or mold spotting on the window sill or nearby baseboard. Chronic moisture intrusion from a failed flashing detail, not window leakage. The roofing membrane behind the window is the culprit, and replacing the window itself won’t solve it.
- Exterior caulking that keeps cracking or pulling away within months of reapplication. The structure is moving because the flashing isn’t managing water load correctly; caulk becomes a band-aid on a drainage problem.
- Bubbling or delamination of exterior paint or stucco near the window head. Water is exiting through the wall face instead of the weep holes, a clear sign the head flashing is dumping behind the cladding rather than onto the roof plane.

AfterReplacement Cost & What’s Included
For ECO Window Systems roofing interface repairs in Fort Lauderdale, most jobs fall between $400 and $1,800 installed. A localized flashing replacement on a single window runs $400-$800; if the roof membrane behind the window is compromised and needs partial redecking, expect $1,200-$1,800. Full roof replacements start at $8,000 and climb based on square footage, pitch complexity, and whether we find compromised decking.
Every quote breaks out parts, labor, and disposal separately. We pull permits when required by Fort Lauderdale building code, and our workmanship carries the 365-Day Done Right Promise: if it’s not done right, we make it right, backed by The Haven Standard, not a handshake. Under Clause 1, the price is written before anyone starts. No change proceeds without a signed change order. You’ll receive a documented photo record of the existing condition, the repair in progress, and the finished detail - standard on every visit, not an upgrade.
DIY or Call Us?

An owner can safely check the window label, measure the flange width, and photograph any visible gaps or staining from ground level or a secure ladder. What you shouldn’t attempt: peeling back roofing membrane, disturbing the sealed joint between window flange and house wrap, or working on a roof pitch steeper than 4:12 without proper fall protection. The membrane-to-flashing bond is a system; disturbing one element without replacing the adjacent components creates a leak path that may not show for months.
We’re an independent service provider - not affiliated with ECO Window Systems - and we’ve handled enough of these interfaces in Fort Lauderdale’s climate to know where the shortcuts fail. If you’re seeing any of the symptoms above, call (754) 254-7676 and we’ll schedule a free estimate with a written line-item quote. Measure twice, write it down, then say it once.
FAQs
The flashing and membrane interface typically lasts 12-18 years in South Florida’s UV and salt-air exposure, shorter if the roof faces west or lacks overhang protection. Call (754) 254-7676 for an exact assessment - estimates are free.
Spot repairs with compatible sealant work for minor adhesion failures under 2 inches, but any lifted membrane or cracked sill pan requires full replacement to maintain the wind-uplift rating. Call (754) 254-7676 for an exact quote - estimates are free.
A single-window flashing replacement takes 3-4 hours; partial roof redecking behind the window runs a full day. We schedule only what we can finish, and we protect the opening with a weather barrier if we need to return. Call (754) 254-7676 to check availability.
We stock compatible flashing profiles, membranes, and fasteners for the Impact Plus, Classic, and Architect series at our Fort Lauderdale warehouse. OEM-specific color-matched trim pieces may need 2-3 days to order. Call (754) 254-7676 to confirm availability for your model.
