ES Windows Roofing Nationwide

ES Windows Roofing: The Fort Lauderdale Owner’s Guide

We stock and install ES Windows-compatible roofing components in Fort Lauderdale, with most replacement jobs running $400-$1,800 installed depending on the component and access. Same-day availability is common for the hardware, flashing, and seal assemblies we carry on our trucks. Most ES Windows roofing failures show up first as a drip line inside the window frame after a hard rain, or as a draft you can’t trace to the sash itself - the roof integration point, not the window glass, is where the water finds its way in.

Which ES Windows Models This Applies To

ES Windows produces impact-rated window and door systems across several series - the ES 100, ES 200, ES 300, and the ES Impact line - and each integrates with roofing differently at the head flashing and saddle detail. The critical match point isn’t the window model alone; it’s the roof-to-wall transition profile ES specified for that installation year, which changed in 2018 when Florida Building Code 7th Edition tightened water-resistive barrier requirements.

To identify your part, check the etched label in the glass corner for the series prefix, then measure the head flashing exposure above the frame - pre-2018 units typically show 2 to 2.5 inches, while post-2018 units run 3 to 4 inches to accommodate the secondary drainage plane. The OEM part carries an ES Windows part number stamped on the aluminum extrusion edge; aftermarket equivalents from Knight Wall or MFM Building Products match the geometry but vary in alloy thickness. We stock both and will show you the spec sheet before quoting - under Clause 1 of the Haven Standard, the price is written before anyone starts.

Signs Your ES Windows Roofing Is Failing

• Water stains on the interior drywall above or beside the window frame. This usually means the head flashing has separated from the roof membrane or the saddle flashing has backed out. In Fort Lauderdale, the thermal cycling between 90-degree afternoons and 75-degree evenings loosens mechanical fasteners faster than in inland climates.
• Visible gaps or lifted edges where the window head meets the soffit or fascia. The sealant bead has failed or the counter-flashing was never properly embedded. We see this often in Victoria Park, where the mature oak canopy traps humidity against the wall plane and accelerates sealant degradation.
• Musty odor or mold spotting in the window track or on the sill. Water is entering behind the window unit and pooling in the rough opening. The ES Windows weep system can’t evacuate water that’s coming from above - the roof integration, not the window drainage, is the problem.
• Increased cooling load or drafts even with the window locked. The roof-to-wall air barrier has compromised. Spray foam or fiberglass in the header cavity has compressed or gotten wet, and conditioned air is escaping through the gap.
• Exterior trim or siding swelling near the window head. Chronic moisture intrusion has saturated the substrate. On older Fort Lauderdale homes with stucco exteriors, this often means the lath behind the stucco has begun to rust - a repair that grows exponentially if the roof integration isn’t fixed first.

Replacement Cost & What’s Included

The range reflects real variables: a single first-story unit with vinyl siding and good attic access sits at the low end; a second-story stucco wall with a 6/12 pitch and no walkable roof sits at the high end. Every quote we write lists the part by name, the labor hours estimated, and the material brand - no bundled charges. The work carries our 365-Day Done Right Promise, and you leave with a documented photo record of the before condition, the opened cavity, and the finished detail.

DIY or Call Us?

There’s a short list an owner can safely check: confirm the weep holes at the window sill aren’t blocked with debris, verify the exterior sealant bead is continuous, and look for obvious fastener pop at the head flashing. These checks cost nothing and sometimes reveal a simple maintenance fix.

Everything else - removing roofing material to expose the flashing, cutting stucco or siding, re-integrating the water-resistive barrier - involves fall risk, structural exposure, and the real possibility of turning a $600 flashing job into a $4,000 wall repair. The head of an ES Windows unit is structural; if you disturb the fastening pattern without knowing the span rating, you’ve compromised the impact resistance the window was certified for. We carry the OEM and aftermarket parts on our trucks, we pull the permit if the repair triggers one, and we write the price before anyone picks up a tool.
