ES Windows Roofing: The San Antonio Owner’s Guide
Mason Remodeling Co San Antonio stocks and installs ES Windows-compatible roofing components, with most replacement jobs running between $400 and $1,800 for repair or $8,000 to $20,000 for a full roof replacement in San Antonio. We carry OEM-spec ES Windows flashing, sealant systems, and trim profiles on our trucks for same-week service in most cases. The way most San Antonio homeowners discover a problem is slow: a water stain appears on the ceiling after a hard Hill Country thunderstorm, or sunlight becomes visible through a gap where the roofing meets an ES Windows frame. It starts small, and then the next rain finds it.
We’re an independent San Antonio contractor, not a division of ES Windows. That matters because it means we give you straight answers about which parts actually need replacing and which ones still have years left. Isaac Pruett has spent enough time on San Antonio roofs to know that ES Windows frames hold up remarkably well in Texas heat, but the roofing materials around them often fail first.
Which ES Windows Models This Applies To
ES Windows produces several series lines, and each has slightly different roofing integration points. The most common in San Antonio homes are the ES Windows 400 Series (aluminum-clad frames) and the 700 Series (full aluminum commercial-grade). The compatibility gotcha we see regularly: homeowners assume all ES Windows products share the same flashing dimensions, but the 400 Series uses a 1-1/4-inch nailing flange while the 700 Series uses a 2-inch flange. If the wrong flashing gets installed, water finds the gap within two seasons. We match the flange measurement before ordering a single component.
To identify your model, look for a metal tag inside the frame near the sash lock, or a laser-etched code on the lower corner of the glass. If the tag is gone, measure the visible flange width and the frame depth. We can match from those numbers. For OEM parts, ES Windows specifies stainless steel flashing and their proprietary sealant compound. Quality aftermarket equivalents exist for the flashing, but we do not substitute aftermarket sealant on ES Windows jobs. The factory compound handles San Antonio’s 100-degree-plus summers without breaking down. The cheap stuff hardens and cracks within three years.

Signs Your ES Windows Roofing Is Failing
- Water staining on the ceiling or wall directly above an ES Windows unit. This usually means the head flashing (the metal cap above the window that directs water away) has pulled loose or corroded. In San Antonio, the freeze-thaw cycles in January and February do real damage to old flashing.
- Gaps between the roof deck and the window frame. Heat expansion in San Antonio summers pushes roofing materials outward. When temperatures drop, they contract. Over years, this cycling opens a visible gap where the roof meets the frame. If you can slide a butter knife into the seam, water is getting in.
- Bubbling or peeling paint on interior walls near the window. Moisture is trapped behind the drywall. The source is almost always the roofing-to-window junction, not the window itself. ES Windows frames themselves rarely leak unless the installation was botched.
- Granules from shingles collecting in gutters directly below an ES Windows unit. That means the shingles around the window are shedding their protective layer. Bare asphalt exposed to Texas sun degrades fast, and the leak follows.
- Daylight visible through the attic around the window header. If you can see light from inside the attic near the top of an ES Windows frame, your flashing is no longer sealed. This is the most definitive sign and also the easiest to check on a sunny San Antonio afternoon.

AfterReplacement Cost & What’s Included
In San Antonio, ES Windows roofing repair typically runs $400 to $1,800 depending on what failed. Re-flashing a single window runs at the lower end. Replacing a section of rotted roof deck and shingles around a window runs higher. If the roof itself is done, full replacement ranges from $8,000 to $20,000 across San Antonio, with metal roof installation starting at $15,000 and going to $40,000 for larger homes.
Every quote from Mason Remodeling Co San Antonio is a written price delivered before any work starts. What drives the range: the number of ES Windows units tied into the roof, the condition of the surrounding deck sheathing, roof pitch and accessibility, and whether we’re matching existing shingle or moving to metal. The price includes parts, labor, removal and disposal of the old material, and our 365-Day Done Right Promise: if the work is not right within a year of completion, we make it right at no cost to you.
DIY or Call Us?
For ES Windows roofing components, there are only two things worth checking yourself. First, look at the attic side of the window header for daylight. Second, clear debris from the roof valley above the window with a leaf blower from the ground. That’s it. Do not get on a San Antonio roof in summer. The surface temperature of a composite shingle roof in July reaches 160 degrees or higher, and ES Windows metal flashing gets hotter. One slip on a steep pitch is not worth the money saved.
What goes wrong with DIY attempts: homeowners apply roofing cement or silicone caulk to the gap they can see, which traps moisture behind the flashing and accelerates rot. We get called six months later to fix a problem that is now worse and more expensive. If you see daylight, a water stain, or a gap at the frame, call (254) 269-5071. We’ll give you a straight answer on what needs replacing and what doesn’t.
FAQs
Roofing materials around ES Windows frames in San Antonio typically last 12 to 18 years before flashing or shingle degradation creates problems, depending on sun exposure and tree cover. The ES Windows frames themselves often outlast the roof by a decade or more. Call (254) 269-5071 and we’ll inspect your specific roofline and tell you honestly how much life is left.
Repair is possible if the flashing has a single small tear or isolated sealant failure, but patched flashing on an ES Windows junction typically fails again within two to three San Antonio storm seasons. We recommend replacement when the flashing is over 10 years old or shows corrosion. Call (254) 269-5071 for a free estimate, and we’ll show you photos of what we found.
Re-flashing or replacing roofing around a single ES Windows unit takes one day for most San Antonio homes, including cleanup. Full roof replacement takes two to five working days depending on the size of the home and the number of window tie-ins. We’ll give you the exact timeline in the written estimate before work begins.
We keep OEM-spec stainless steel flashing, ES Windows-compatible sealant compound, and standard trim profiles on our trucks for the 400 and 700 Series. Specialty sizes and full window replacement units are ordered and arrive within five to seven business days in San Antonio. Call (254) 269-5071 to confirm we have your part before you schedule.
