PGT Roofing: The Pasadena Owner’s Guide
If you have a PGT roof window, skylight, or venting unit that’s failed, we can source and install the correct PGT-compatible replacement part in Pasadena, typically completed in one visit. Most PGT roofing component replacements run between $400 and $1,800 installed depending on the part, the roof pitch, and how much flashing work is involved. The most common way owners find us is the slow leak: a water stain on the ceiling that appears after the first real rain of the season, then widens through February.
PGT is best known in California for impact-rated windows and doors, but their roofing line, particularly their skylight and roof-window series, shows up on homes across Pasadena from Bungalow Heaven to Hastings Ranch. When a PGT roofing unit fails, it’s rarely the glass itself. It’s the seal, the flashing kit, or the hardware that connects the unit to the roof deck. That’s good news, because it means the fix is usually a component swap, not a full re-roof.
Which PGT Models This Applies To
PGT’s roofing products fall into a few families, and the replacement part has to match the specific series. The PGT WinGuard roof window line, for example, uses a different flashing profile than their standard venting skylight. The model number is printed on a label inside the frame, usually on the left side rail, and it looks like a short string of letters and digits, not a bar code. If the label has faded from sun exposure, which happens quickly on a south-facing Pasadena roof, we can still identify the unit by measuring the rough opening and checking the glass thickness against PGT’s spec sheets.
One compatibility gotcha we run into often: PGT flashing kits are not universal across their product lines. A flashing kit for a WinGuard roof window will not seat correctly on a PGT fixed skylight, even if the rough opening is the same size. That’s the kind of detail that causes a “repaired” unit to leak again the following winter. We match OEM PGT parts whenever they’re still in production. For older units where PGT has discontinued the part, we source quality aftermarket equivalents that match the original glazing dimensions and load rating. We also work with KraftMaid, Cambria, and Silestone on the interior side of these projects, which matters when a leak has damaged drywall or the ceiling around the skylight shaft.
Styles & brands we work with
Signs Your PGT Roofing Is Failing
- Water stain on the ceiling spreading outward from the skylight shaft. This almost always points to a failed flashing seal where the PGT curb meets the roof membrane, not a crack in the glass. The seal degrades under constant UV exposure and the temperature swings we get in Pasadena between August and January.
- Condensation between the glass panes. That’s a failed insulated glazing unit. The argon or krypton fill has escaped through a broken edge seal. You can’t wipe it away from either side because the moisture is trapped inside the unit itself.
- Visible cracks or chips in the outer glass layer. On impact-rated PGT units, the outer pane can take a hit from a roof tile during a Santa Ana wind event and crack without the inner pane failing. The unit still holds, but the structural rating is gone until you replace it.
- Hardware that won’t close, latch, or stay open. PGT roof windows use a specific hinge and crank mechanism. When the hardware wears out, the window won’t seal tightly, and even a small gap lets conditioned air escape and rain find its way in.
- A draft you can feel near the skylight on cold nights. This is the canary in the coal mine. The gasket between the sash and the frame has compressed and hardened. It may not leak visibly yet, but the seal is no longer doing its job.

AfterReplacement Cost & What’s Included
In Pasadena, PGT roofing part replacement runs $400 to $1,800 installed, with full roof or window replacement projects running higher, from $8,000 to $20,000 when the roof deck itself is involved. The spread depends on three things: which PGT part failed, whether the flashing kit needs to be re-formed to match an existing roof profile, and how much interior repair is needed if water got into the ceiling drywall.
| Part | Installed Price Range |
|---|---|
| PGT flashing kit replacement | $400 – $900 |
| PGT gasket and seal replacement | $450 – $1,100 |
| PGT roof window hardware (hinge/crank) | $500 – $1,200 |
| PGT insulated glazing unit replacement | $600 – $1,600 |
| Full roof replacement over PGT unit | $8,000 – $20,000 |
Every quote from us is a written, line-item price before any work starts. The price on paper is the price you pay at the end, no footnotes. That’s how Graham Stein runs things, and it’s how the whole crew works, from the first measurement to the final photo of the clean-up.
DIY or Call Us?
There’s a safe middle ground here. You can inspect the interior frame for the model label, check the ceiling for water stains after the first big rain, and take photos of any visible cracking or condensation. Those photos genuinely help us prepare before we arrive. What we don’t recommend is getting on the roof yourself. Pasadena roofs tend to be steep in the older Craftsman neighborhoods, and a failed flashing seal is often worse than it looks from the ground. Slipping on a terra cotta tile ridge is a life-changing injury, not a weekend project. If the PGT unit involves high-tension hardware or the roof pitch is anything beyond a mild slope, have a trained professional handle it, including the inspection. We’re happy to come out and look before you decide anything. Call (626) 714-2992 and we’ll set up a time.
FAQs
A PGT roof window or skylight in our climate typically lasts 15 to 25 years, with the edge seals and gaskets being the first things to go, usually around year 12 to 15. The intense Pasadena sun is harder on the seals than the glass. Call (626) 714-2992 and we’ll help you figure out what’s still under warranty and what’s worth replacing.
Gaskets and some flashing components can be re-sealed and re-bedded, which is a repair. But a failed insulated glazing unit or a cracked outer pane needs a full replacement, no way around it. When we inspect the unit, we’ll tell you which category you’re in before we recommend anything.
Most single-unit PGT part replacements are done in one day, including clean-up. The exception is when water damage has spread into the ceiling drywall around the skylight shaft, which adds a day or two for interior repair. We’ll tell you the timeline in the written quote, not in a follow-up call.
We stock the common items: flashing kits, gaskets, and hardware for the PGT series most often installed in Pasadena. For insulated glazing units, which are made to the exact dimensions of your unit, we order directly from the PGT spec sheet and install as soon as it arrives. Call (626) 714-2992 with your model number and we’ll check availability right then.
If your PGT roofing component has failed and you want a written price before anyone touches the roof, call (626) 714-2992 for a free estimate. We’ll measure, match the part, and tell you exactly what it will cost, before a single drop cloth goes down.
