ES Windows Roofing Nationwide

ES Windows Roofing: The Los Angeles Owner’s Guide

If you have an ES Windows roof window, skylight, or roof-integrated glazing system and a part has failed, we stock ES Windows-compatible roofing components and install them across Los Angeles, often within the same week. Installed replacement work typically runs from $470 to $2,125 depending on the part and the access, and we give you a written price before any work starts. Most owners discover a failure the same way: a water stain on the ceiling after rain, a crank that suddenly spins without moving the sash, or a latch that no longer seals tight against the curb. The part that failed is usually not the glass. It is the flashing, the gasket, or the hardware around it, and those are replaceable without tearing out the whole unit.

Which ES Windows Models This Applies To

ES Windows builds several roof-facing product lines, and the part you need depends on which one is installed. Their operable roof windows and fixed skylights use a modular curb-mount or deck-mount frame, and the gaskets, hinges, and operators are series-specific. Before you order anything, open the sash and look for a small metal or foil tag on the frame edge. It will list a model prefix and a production date. That prefix is the single most useful piece of information you can give us, because a hinge for a 2009 unit will not always fit a 2018 unit even when both look identical from the ground. Glass size alone is not enough. We carry OEM ES Windows hardware where it is still available and high-quality aftermarket equivalents where the OEM part has been discontinued. For gaskets and weatherstripping, aftermarket EPDM profiles matched to the exact channel dimensions frequently outlast the original material, especially in Los Angeles sun exposure. We also carry flashing kits, curb assemblies, and insect screens sized to the original rough opening. One compatibility note that catches people off guard: ES Windows curb heights changed on some roof window lines around 2015. If your unit dates from before that and you are replacing the curb rather than the hardware, the new curb may sit slightly taller or shorter. We measure before we order, every time.

Signs Your ES Windows Roofing Is Failing

• Water staining on the ceiling below the unit. This usually means the flashing or the gasket between the glass and the frame has degraded, not that the glass itself is cracked. The fix is often a flashing replacement and new gasket, not a full unit swap.
• The sash crank spins freely or binds. The operator mechanism or the hinge arms have worn out. These are serviceable parts, and replacing them restores the window to proper function without touching the glass or the roof membrane.
• Condensation between the glass panes. The insulated glass unit seal has failed. In Los Angeles, the temperature swings between coastal fog mornings and hot inland afternoons accelerate this failure. The glass unit gets replaced while the frame stays in place.
• Daylight visible around the closed sash. The gasket or weatherstripping has compressed or cracked, usually after years of sun exposure on the south-facing slopes common in Los Angeles. The seal can be replaced as a standalone part.
• The latch no longer pulls the sash tight against the frame. Latch wear is a mechanical problem, not a structural one. New latch hardware is a quick, predictable replacement and we keep common sizes on the truck.

Replacement Cost & What’s Included

In Los Angeles, a single ES Windows roof window or skylight part replacement typically lands between $470 and $2,125 installed. The range exists because of a few real variables: how steep the roof is, how many stories the home has, whether the part is OEM or aftermarket, and whether the flashing needs to be reworked. A gasket or latch replacement sits at the lower end. A full curb and flashing replacement on a two-story home with a steep roof runs toward the top. The line-item quote you get from us shows the part cost and the labor separately, and that number does not change once we start. If we open the roof and find the curb is in worse shape than expected, we stop, take photos, and get your sign-off on the difference before any additional work happens. Our workmanship on ES Windows roofing replacements is covered by the 365-Day Done Right Promise. If the part or the install is not done right, we make it right.

DIY or Call Us?

You can safely do some diagnosis from inside the house. Close the sash and run your hand along the gasket. If the rubber feels brittle or has visible cracks, that is likely the culprit. Check the crank mechanism with the sash open; if the operator gears slip, that is a hardware replacement. What you should not do is get on the roof to remove flashing or a curb without experience. Roof work on any sloped surface carries real fall risk, and getting the flashing lap direction wrong will redirect water under your roofing rather than over it.
