ES Windows Roofing: The Boca Raton Owner’s Guide
ES Windows roofing components in Boca Raton typically run $400-$1,800 for repair and $8,000-$20,000 for full replacement, with most common part failures resolved same-day when we stock the match. We carry ES Windows-compatible flashing, membrane transitions, and integrated window-to-roof seal assemblies on our trucks because Boca Raton’s driving rain and salt air degrade these interfaces faster than inland Florida markets. Most owners discover the failure after a storm when water tracks down the window jamb and pools at the sill, or when their energy bill jumps and the infrared camera shows thermal bridging at the roof-wall intersection.
Which ES Windows Models This Applies To
ES Windows manufactures impact-rated aluminum and vinyl window systems across several series, and the roofing interface parts vary by frame depth and installation method. The ES 5000 Series and ES 8000 Impact Series use a proprietary extruded sill pan with integrated weep screed, a channel that drains water to the exterior, while older ES 3000 units relied on a simpler flashing apron sealed with backer rod and polyurethane. The label is stamped on the top rail of the operable sash or fixed frame, usually a small aluminum badge with a six-digit serial prefix.
To identify the right roofing transition part, measure the frame depth from interior drywall to exterior stucco or siding. The 5000 Series runs 4-9/16 inches, the 8000 runs 6-9/16 inches for impact laminates, and the 3000 runs 3-1/4 inches. Order the wrong depth and the pitch of the roof-to-wall flashing changes, creating a lip that traps water. We stock OEM ES Windows sill pans and also source from Custom Window Systems and PGT for compatible aftermarket equivalents when the lead time on factory parts stretches past what Boca Raton’s afternoon thunderstorms allow. The aftermarket pans match the extrusion profile but use a heavier-gauge aluminum, 0.050 inch versus ES’s 0.040 inch, which we prefer for coastal exposure.
Signs Your ES Windows Roofing Is Failing

- Water staining on the interior drywall below or beside the window. This usually means the head flashing, the metal diverter that carries roof runoff over the window frame, has separated from the stucco or the sealant has hardened and cracked. In Boca Raton, the thermal expansion cycle from 95-degree afternoons to 72-degree air-conditioned interiors fatigues sealant in three to five years, faster than the manufacturer’s inland spec.
- Soft or discolored trim boards beneath the window sill. The weep screed is clogged with stucco debris or paint, so water that enters the frame cavity has nowhere to exit except through the fascia board. We see this most in Spanish River Land and Boca Harbour homes where painters have sealed the weep holes to “clean up” the line.
- Visible rust on the exterior flashing or exposed fasteners. ES Windows used zinc-coated steel screws on pre-2018 production, and the salt air in Boca Raton converts these to powder in four to six years. The rust expands, cracks the surrounding sealant, and opens a direct path for wind-driven rain.
- Window operation becomes stiff or the sash won’t lock. This is often misdiagnosed as a balance or hardware issue, but roof leakage into the frame swells the vinyl or corrodes the aluminum track. The frame goes out of square by as little as 1/8 inch and the sash binds.
- Mold or mildew odor concentrated near the window. Chronic moisture in the roof-wall cavity breeds mold on the OSB or plywood sheathing before it ever shows on the interior face. By the time you smell it, the sheathing is often punky and the repair scope has grown from a flashing swap to structural replacement.

AfterReplacement Cost & What’s Included
In Boca Raton, ES Windows roofing interface repair runs $400-$1,800 depending on whether we’re replacing a single flashing leg or rebuilding the entire sill pan with adjacent sheathing. A full roof replacement with ES Windows integration runs $8,000-$20,000 based on square footage, pitch, and whether the deck needs recovery or complete redeck. Here’s how the repair range breaks:
- Flashing replacement, sealant, and touch paint: $400-$650
- Sill pan replacement with weep screed cleaning: $800-$1,200
- Sill pan plus localized sheathing repair: $1,200-$1,800
Every quote is a flat written price with line-item scope before work starts, under Clause 1 of the Haven Standard. The price includes removal and disposal, new fasteners in 316 stainless for coastal corrosion resistance, and a photo record of the cavity condition before we close it up. Our 365-Day Done Right Promise covers the workmanship; the flashing material itself carries the manufacturer’s 20-year warranty against defects.
DIY or Call Us?

An owner can safely check the weep screed for blockage with a piece of wire and confirm the window label series from the interior. Do not attempt to remove or replace roof-to-wall flashing yourself. The work requires ladder positioning on a pitched surface, removal of stucco or siding that may contain asbestos in pre-1985 Boca Raton construction, and proper integration with the water-resistive barrier, the housewrap or felt layer behind the cladding. Get the sequence wrong and you channel water into the wall cavity instead of over it.
We carry ES Windows-compatible parts on our trucks for most common failures, and we pull permits when the repair exceeds 25 percent of the roof surface or involves structural sheathing, per Boca Raton building department requirements. Call (754) 254-8065 to schedule your free estimate. We’ll match the part, write the price, and show you the photo record before we leave.
FAQs
Flashing and sealant typically last 7-12 years in Boca Raton’s coastal environment, shorter than the 15-year inland rating, due to salt corrosion and UV exposure. The 316 stainless fasteners we install extend that by resisting the galvanic reaction that destroys standard hardware. Call (754) 254-8065 for an exact quote on replacement - estimates are free.
Spot sealant repair buys one to two years at most and we don’t recommend it as a permanent solution. The original sealant has already failed, and new sealant won’t bond reliably to oxidized aluminum or compromised housewrap. We replace the flashing leg and start with clean substrate so the new sealant achieves full adhesion. Call (754) 254-8065 for an exact quote - estimates are free.
A single flashing or sill pan replacement takes three to five hours, including stucco or siding removal and replacement. Full roof replacement with ES Windows integration runs three to five days depending on square footage and deck condition. We don’t start until the written price is signed, and no phase proceeds without sign-off on the photo record from the previous one. Call (754) 254-8065 to schedule your free estimate.
We stock compatible flashing, sill pans, and sealant assemblies for the ES 5000 and 8000 Series on our trucks, and we can source OEM ES Windows parts within 48 hours for older 3000 Series units or color-matched extrusions. Our inventory includes the heavier-gauge aftermarket pans we prefer for Boca Raton’s salt air exposure. Call (754) 254-8065 for an exact quote - estimates are free.

Grant Rowan’s first framing square came from his father at age nine, working on a 1960s Beverly Hills ranch house. Two decades in the field taught him that buildings fail at the interfaces, where the roof meets the wall and the window meets the flashing. His crews in Boca Raton document every phase before the next one begins, because “measure twice, document everything, then build” is the only way a project finishes within a few percent of the number the customer agreed to.
