ES Windows Roofing: The Woodland Hills Owner’s Guide

If you’ve got an ES Windows product with a failed roof flashing, curb, or seal assembly, we stock and install compatible replacements in Woodland Hills, with most jobs running $400 to $1,800 installed depending on the part and access. Most owners find us because water started showing up where it shouldn’t be, or because a skylight or window roof curb cracked after one of our valley heat waves and a cold snap followed right behind it. Here’s the full picture so you know exactly what you’re dealing with before you spend a dime.

Which ES Windows Models This Applies To

The roofing components that fail on ES Windows products aren’t the glass. They’re the metal or membrane curb, the flashing skirt, and the sealant bed that ties the unit into the roof deck. These are similar in function across ES Windows’ fixed and operable roof systems, but the dimensions and mounting patterns change by unit size and glass package, which is why measuring before ordering matters. Look for the manufacturer label on the frame, typically etched into one corner or printed on a sticker behind the interior trim ring. You’ll see a series code and dimensions in millimeters. That code, not the year of install, is what tells us the correct flashing profile. ES Windows makes their curb extrusions to tight tolerances, and a “close enough” universal curb will leave you with gaps that show up as leaks within a year or two. For owners deciding between genuine ES Windows replacement parts and quality aftermarket equivalents, the rule is simple: if the part is structural or waterproofing, go OEM or manufacturer-matched. If it’s a trim ring, insect screen, or interior diffuser, a well-made aftermarket part is fine. We keep both on the truck for common Woodland Hills units.

Signs Your ES Windows Roofing Is Failing

• Water staining at the ceiling corners or around the drywall opening. This usually means the flashing skirt has lifted or the sealant bed has dried and cracked. In Woodland Hills, the dry heat cycles bake sealant faster than you’d expect, which is why we see this on units only six or seven years old.
• Visible cracks in the curb or flashing skirt. ES Windows aluminum curbs expand and contract with temperature. Over enough 90-degree summers and 40-degree winter mornings, stress cracks form at the screw points. A cracked curb isn’t a sealant repair; it’s a replacement.
• Daylight visible through the corner seams from inside. This is the clearest sign the curb-to-flashing interface has opened up. It’s also the one that most often gets ignored because it looks small, while water wicks through and rots the decking below.
• Condensation between the roof glass and the ceiling diffuser. This typically points to a failed interior seal, not the roof flashing itself. The glass unit has lost its seal and is cycling humidity. Replacing the roof flashing won’t fix it; the glass panel or its edge gasket needs attention.
• Drafts or temperature swings directly under the unit. An open gap in the roof curb lets conditioned air escape and outside air in. Your energy bill will tell the story before your eyes do, especially on Woodland Hills afternoons where every cooled cubic foot counts.

Replacement Cost & What’s Included

For ES Windows roofing repair or replacement in Woodland Hills, you’re looking at $400 to $1,800 installed. The spread comes down to three things: which part failed, how hard the roof is to access, and whether we’re repairing a sealant bed or swapping a full curb assembly. A simple flashing reseal with the right commercial-grade sealant usually lands near the bottom of that range. A full curb replacement with new OEM flashing, re-bedding, and clean-up of the surrounding roof membrane runs toward the top. Every quote from us is written and line-itemed before work starts, so you’ll see exactly what the parts cost and what the labor costs. The number we write is the number you pay. We back the work with our 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, on every repair.

DIY or Call Us?

You can safely check a few things yourself: look for daylight at the corners from inside, photograph the curb from a ladder at the eave if you have a safe vantage, and note whether the stains are growing after rain. What you shouldn’t do is get on the roof with a tube of sealant and start caulking over failed flashing. Roof work on a pitched Woodland Hills hillside is where we see homeowners get hurt trying to save a few hundred dollars, and a bad patch job hides the real failure until the decking is gone. If the part is failed, not just dirty, the fix is always a proper replacement or re-flash, not a bead of silicone. Call us at (341) 217-2776 and we’ll come look, quote it in writing, and tell you straight whether it’s a repair or a replacement.
