ES Windows Roofing: The Tampa Owner’s Guide

If you’re reading this, you’ve likely got an ES Windows product on your roof or upper-wall opening and something has failed: a flashing detail pulling away, a glass seal fogging where it meets the roof deck, or a leak that shows up at the ceiling line every time a summer storm rolls through Tampa. ES Windows roofing refers to the integration of ES Windows’ impact-rated glass units with the roof structure, typically found on second-story eyebrow windows, clerestories, or skylight-adjacent openings in Tampa homes. In Tampa, owners with this setup usually reach us after noticing water staining along the interior wall, condensation between glass panes, or a draft audible during the wind events Florida is known for. The cost to repair or replace ES Windows roofing components in Tampa ranges from roughly $400 for a flashing reseal to $2,500 when the surrounding roof deck and original window unit both need attention. Most jobs are completed within one or two days once the right part is in hand.

Which ES Windows Models This Applies To

Before we order anything, we confirm which ES Windows series you’re working with, because the flashing kits and installation collars differ between lines. ES Windows produces three main series: the ES-700 Series for standard residential use with a shallower frame depth, the ES-900 Series designed for coastal wind zones with deeper extrusions, and the ES-1000 Series for large-format openings where the window carries structural load that a roof cut once handled. Each series uses a different aluminum profile depth, and that measurement determines which roof curb, sill pan, and head flashing will actually fit. You can usually find the model etched into the corner of the glass itself or on a small factory sticker inside the frame. If the sticker is gone, we measure the frame depth and the glass thickness on site; that’s been the most reliable way to match parts on older Tampa homes where paperwork has been lost through two owners and a hurricane season. For a roof-integrated unit, we strongly recommend OEM parts from ES Windows when the frame itself is being replaced, but aftermarket flashing kits and sealants from GAF and similar roofing-material makers often perform equally well where the failure is purely at the roof-to-window joint. One compatibility gotcha we see on Tampa homes: a unit installed before the 2012 code cycle often has a narrower flange than current ES-900 replacements, so a straightforward swap sometimes requires building up the roof curb by a half-inch. That’s a known issue we check for before we quote it.

Signs Your ES Windows Roofing Is Failing

• Water stain at the ceiling line in the room below. In almost every case in Tampa, this means the head flashing above the window has lifted or the sealant bead has dried in the heat. Rain gets behind the flashing and travels down the sheathing until it finds a drywall seam to show itself.
• Fog or condensation trapped between the glass panes. The insulated glass unit seal has failed, usually after ten or more years of direct Florida sun. The frame can be fine while the glass itself needs replacement; we often reuse the frame and install a new sealed unit.
• Draft you can feel with the window closed. This points to a failed weatherstrip where the sash meets the frame, or a gap that opened at the roof curb from normal thermal movement. It worsens in summer when the aluminum frame expands.
• Daylight visible through the flashing joint at the roofline. This is a mechanical failure, not a cosmetic one. The head flashing has pulled far enough that water and pests both have an entry point.
• Soft spot where the ceiling meets the window well. By the time surface softness shows up, water has been sitting on the subfloor or strapping for a while. In Tampa, this is often a slow leak from a torn sill pan at the lower edge of the unit.

Replacement Cost & What’s Included

Roof repair for an ES Windows integration runs $400 to $1,800 in Tampa when the scope is flashing, sealant, and roof-deck remediation. A full ES Windows unit replacement that includes cutting the old frame free, rebuilding the curb if needed, and tying the new unit into your roof with new underlayment runs $800 to $2,500 depending on the series and the glass configuration. Tile roof repair on the same detail sits between $600 and $2,500 because we’re often hand-trimming clay or concrete tile around the curb and resetting them with new fasteners. The wide range accounts for what we find only after the first layer is off: a second-story eyebrow window over a steep compound roofline is different from a clerestory with a flat deck behind it. Every quote we write is a fixed number with parts and labor separated on the page, and it doesn’t change when we find the half-inch flange issue we mentioned above. That’s the point of writing it down before we start: nobody is guessing mid-project, and you know the cost before the first tool comes off the truck.

DIY or Call Us?

For this particular job, the honest answer is that most owners should call us. The glass itself is laminated and heavy; a failed insulated unit on a second-story roof opening is not something to muscle up a ladder past pool decking. The more serious hazard is the work at the roofline: if your roof pitch is steeper than 6 in 12, or if we’re looking at a tile roof with glass below it, a good outcome depends on fall protection, a helper, and a very specific order of operations for lapping the underlayment. If you’d still like to know what’s happening before we arrive, you can safely check a few things from the inside: feel for drafts at the lower corners on a windy day, look for new staining after a storm, and take a photo of the unit from the yard with your phone zoomed in so we can see which series we’re matching. What we’d rather you not do is climb up with a caulk gun and seal over failed flashing; that hides water and gives it more time in the wall. Call us at (850) 779-4017 and we’ll walk you through what we’re seeing before we schedule a free estimate.
