PGT Roofing: The San Antonio Owner’s Guide
If you’re dealing with a failing PGT roofing component in San Antonio, we stock the parts and can typically complete the install for $400 to $1,800 depending on the part and scope. Most PGT roofing issues we see around Bexar County are discovered after a storm rolls through or when a homeowner notices water staining on a ceiling. The good news is that PGT parts are widely available, and our crews carry the most common replacement parts on the truck. We’ll match your PGT model, give you a written price before any work starts, and stand behind the repair for a full year.
This page covers PGT roofing specifically. Mason Remodeling Co San Antonio is an independent service provider, not affiliated with PGT. We also stock parts for KraftMaid, Cambria, and Silestone if you’re working on other areas of the home.
Which PGT Models This Applies To
PGT primarily manufactures impact-rated windows and doors, but many San Antonio homes have PGT skylights, roof flashing components, and the integrated roofing seals that come with those window systems. The parts we most often replace include skylight flashing kits, curb-mounted skylight gaskets, impact window roof flashing, and the weather stripping that seals the joint where a PGT window meets the roofline.
Here’s the compatibility gotcha we see constantly: PGT changed their skylight flashing dimensions between their older 2000-series and newer 5000 and 7000 series models. A flashing kit labeled for the 2000 series will not seat properly on a 5000-series curb. The curb height and screw hole spacing are different by roughly three-quarters of an inch. Before you order anything, check the etched label on the inside frame of your skylight or the aluminum tag on the window sash. That tag has your exact model number. If it’s worn off, take two measurements: the rough curb opening width and the curb height above the roof deck. We’ll match those numbers rather than guess.
OEM versus aftermarket matters here. PGT’s own flashing kits are engineered to the exact thermal expansion rate of their frames, which matters during San Antonio’s 100-degree summer afternoons followed by 60-degree nights. Quality aftermarket kits exist and can save 20 to 30 percent, but cheaper generics often fail at the corner welds within two or three seasons. We’ll tell you plainly which aftermarket lines we trust and which ones we won’t install on a PGT opening.
Styles & brands we work with
Signs Your PGT Roofing Is Failing
- Water staining on the ceiling near a skylight or roof window. The gasket between the glass unit and the aluminum frame has lost its compression. Sun exposure in San Antonio breaks down that gasket material faster than the national average, usually around the 8 to 12 year mark.
- A drip or water trail on the interior drywall below a roof-mounted PGT window. The flashing has pulled away from the roof deck. This often follows a windstorm or HVAC vibration loosening the fasteners. Flashing that was sealed with caulk alone, rather than a proper step-flashing system, is the usual culprit.
- Condensation between the panes of a PGT skylight. The insulated glass unit’s seal has failed. In San Antonio’s humid climate, this shows up as fogging that won’t wipe away. The glass unit gets replaced, not just the seal.
- Visible cracks or lifting at the flashing corners around the roof opening. Repeated thermal cycling from our hot afternoons to cool nights causes aluminum flashing to expand and contract. Corners are the first place that stress shows. Once a corner lifts, water follows within a single storm season.
- Soft spots on the roof deck when you’re in the attic near a PGT opening. This is the late-stage version. Water has been getting past the flashing and soaking the decking. The good news is the repair can still be straightforward if caught before the structural framing is compromised.

AfterReplacement Cost & What’s Included
For PGT roofing-related parts in San Antonio, installed pricing typically falls between $400 and $1,800. A skylight gasket replacement on a curb-mounted unit runs $400 to $800. Full flashing kit replacement with roof deck inspection sits between $700 and $1,500 depending on roof pitch and access. A complete PGT skylight glass unit replacement runs $900 to $1,800.
What drives the range? Roof access is the big one. A single-story walkable roof keeps us on the lower end. A steep second-story pitch in a neighborhood like Terrell Heights requires safety staging and takes longer, which costs a bit more. The part itself also matters: OEM PGT flashing costs more than a trusted aftermarket kit, but you get the exact expansion-matched fit.
Every quote we write in San Antonio includes the part, all labor, removal and disposal of the failed component, and our written workmanship guarantee. That guarantee runs 365 days from the completion date, in plain language. If the repair fails within a year, we come back and make it right at no charge. No dispute process. No conditions.
DIY or Call Us?
We’ll be honest with you about this. There are things you can check yourself, and there are things you should leave alone. You can safely check the interior ceiling for water stains, look for visible flashing lifting from the roof edge with binoculars from the ground, and note the exact model number on your skylight or window tag. That saves time when you call.
What you shouldn’t do is get up on a San Antonio roof in July to remove flashing yourself. The roof surface gets hot enough to cause second-degree burns through denim, and a fall from even a single-story roof changes your life. More practically, resealing flashing with a caulk gun from the home center may buy you a month, but the problem underneath keeps leaking. We see it constantly: a homeowner spends a weekend up there, then calls us anyway when the stain spreads. Save yourself the Saturday. Call (254) 269-5071 and we’ll do the full diagnosis, written quote, and repair correctly the first time.
FAQs
Expect 10 to 15 years from PGT flashing kits and gaskets in San Antonio’s climate before the heat and UV exposure start breaking down the materials. We see earlier failures on west-facing roof openings that get the full afternoon sun. If you’re past year 12 on original PGT components, start watching for the symptoms listed above.
Yes, in most cases. If the glass is intact and it’s the gasket or flashing that failed, we repair those individually without touching the glass unit. If the insulated glass seal has failed and you’re seeing fogging between panes, the glass unit itself gets replaced, not the whole skylight frame. Call (254) 269-5071 and we’ll tell you which situation you’ve got based on the symptoms.
Most flashing or gasket replacements take our crew two to four hours on site. A full glass unit replacement on a curb-mounted PGT skylight is usually a half-day job. If the roof deck underneath has water damage, we’ll add the decking replacement time, which can push the job into a full day.
We stock the most common PGT flashing kits and gaskets on our trucks for the 5000 and 7000 series models. Specialty sizes and full glass units are typically available to us within a few business days from our San Antonio suppliers. When you call for an estimate, the person on the phone can confirm what we’ve got on hand against your exact model number.
If you’re ready to price this out, call (254) 269-5071 for a free estimate. You’ll get a written price before any work starts, and the crew that arrives will have been introduced to you by name and photo before they ever pull in the driveway. Know who’s coming, know what it costs, know it’s covered – that’s the whole job before the job starts.
