AfterPGT Roof Replacement & Installation in Mangonia Park: What to Know First
PGT roof replacement and installation in Mangonia Park typically runs $9,800 to $24,500 depending on roof size, material choice, and whether we’re replacing decking or just the surface layer. Most PGT-adjacent roofing work here is completed in 3 to 5 working days once materials land. We quote the full job upfront, in writing, with no change orders unless you ask us to change the scope.
This page is for Mangonia Park homeowners with PGT-branded exterior products who need a roof torn off and rebuilt, or a new roof installed over a fresh build. If you own PGT windows or doors and the roof around them is failing, you need a roofer who understands how PGT products integrate with flashing, underlayment, and load paths. Call (561) 928-0302 and you’ll get a live person, not a voicemail tree.
How PGT Products Fail - and How We Fix Them
PGT makes excellent windows and doors, but several of their lines have known interaction points with roofing that we see again and again across Mangonia Park homes. Here’s what actually goes wrong and what we do about it.
- PGT WinGuard frame-to-deck flashing separation. The WinGuard line is built for impact, but the aluminum frame has a shallow flange that roofers often under-flash. In Mangonia Park, where afternoon thunderstorms roll through most summer weeks, that gap becomes a water channel within one season. We pull the old flashing, inspect the frame for corrosion, and install a stepped flashing detail that overlaps the WinGuard flange by a full inch.
- PGT 5500/7700 series perimeter rot from trapped moisture. These vinyl lines hold up well, but the rough opening around them is where roof leaks concentrate. By the time a Mangonia Park homeowner sees the ceiling stain, the sill has usually been sitting wet for months. We don’t just patch the decking around the frame; we expose the opening, dry it out, replace any compromised wood, and re-seal with a membrane that extends past the frame corner.
- Roof-to-wall transition failures against PGT sliding glass door tracks. Homes with PGT SGD-series sliders built on slabs often have the roof terminating directly above the door track. When the step flashing at that transition fails, water rides the track straight into the wall cavity. The fix is a full re-flash of that transition with a custom pan, not another bead of caulk.
- Improper aftermarket flashing kits on PGT casement hinges. We see roofers use generic Z-flashing around PGT casement windows with the hinge mounted high. That spot takes the most water in a Mangonia Park downpour. We fabricate the flashing on site so the hinge throw isn’t obstructed and the seal is continuous.
- Underlayment breakdown accelerated by Mangonia Park’s humidity cycle. Synthetic underlayment can delaminate faster here than in drier parts of Palm Beach County because of the constant wet-dry cycle. When we strip a roof, we look at what’s under it. If the underlayment has failed, we replace it with a high-grade synthetic rated for high-humidity, high-heat exposure before the new roof goes on.
Our PGT Roof Replacement & Installation Process
Every PGT roof job in Mangonia Park follows the same sequence. No shortcuts, no surprises.
- 1
Call and schedule a site visit. You reach a live person at (561) 928-0302. We set a time that works for you, and the tech shows up in uniform with a background check already on file.
- 2
Full roof and perimeter inspection. We inspect the entire roof surface, the decking from inside if the attic is accessible, and every penetration around PGT windows, doors, and sliders. We document everything with photos and show them to you on the spot.
- 3
Written line-item quote. You get the full scope in writing: materials, labor, decking replacement if needed, flashing work around every PGT product, disposal, and any permit fees. No verbal estimates, no “we’ll figure it out later” language.
- 4
Material selection and scheduling. We go over shingle, tile, or metal options with real pricing, not brochure language. Once you approve the quote, we order materials and set a start date. Permits get pulled and inspections get scheduled as part of the job.
- 5
Installation day. The old roof comes off, the decking gets inspected and repaired, underlayment goes down, the new roof goes on, and every PGT perimeter point gets flashed and sealed correctly. The crew cleans up daily; we don’t leave nails in your driveway.
- 6
Final walkthrough and warranty. We walk the roof with you, show you the flashing, point out the tie-ins around your PGT products, and hand you the warranty paperwork. If anything’s not right, it’s covered under the Done Right Promise.
What PGT Roof Replacement & Installation Costs in Mangonia Park
Straight numbers, because you asked. For a typical Mangonia Park single-family home:
- Asphalt shingle tear-off and replacement, 1,800 sq ft: $9,800 to $14,600
- Full PGT perimeter re-flashing during roof replacement (windows, doors, sliders): $1,200 to $3,400 depending on count and condition
- Decking replacement per 4×8 sheet (if rot is found): $85 to $140 per sheet, installed
- Tile roof replacement, 1,800 sq ft: $18,000 to $24,500
- Metal roof installation, 1,800 sq ft: $15,500 to $22,000
What moves the price: roof pitch, number of PGT penetrations, how much decking is rotted, and whether your existing flashing was done right the first time. Most houses in Mangonia Park need at least some decking replaced, because the humidity here eats plywood faster than people expect. Call (561) 928-0302 for a free estimate, and we’ll give you the real number for your roof.
Why Mangonia Park Homeowners Call Winslow Windows & Doors for PGT Work
My name is Ed Winslow. I grew up in Mangonia Park, not far from the old Mangonia Park Town Hall, and I still live close enough that I run into my customers at the hardware store on a Saturday morning. That changes how we work. When a neighbor’s roof is leaking, I’m not a ticket number in a call center; I’m the guy who shows up with a crew and makes it right.
We’ve been doing this since 2011. Every roof job gets the Done Right Promise: if it’s not done right, we make it right. Every technician who steps onto your property is background-checked and in uniform. We answer the phone 24/7 with a live person. And because we’re an authorized installer for PGT, CGI, CWS, ES Windows, and ECO Window Systems, we understand how a roof ties into the rest of your exterior, not just where to nail shingles.
FAQs
In most cases, PGT’s warranty covers the product itself, not the installation or the flashing around it. A roof replacement done by a contractor who damages a PGT frame or fails to re-flash it properly can void the product warranty on that unit. We handle every PGT perimeter point with the same care we’d use installing the window new, and we document the work so your warranty stays intact.
PGT doesn’t manufacture flashing kits for roof work, so every roofer uses fabricated or aftermarket materials. The difference is in how it’s done. We fabricate on site to match the exact profile of your PGT frames, which is why our flashing holds up through Mangonia Park storm seasons instead of failing in year two.
If your PGT windows are approaching the end of their service life, doing both at once saves money on flashing and labor, because we only have to open each perimeter once. If the windows are still in good shape, we can replace the roof and re-flash every PGT unit without touching a single frame interior. We’ll tell you honestly which makes sense for your situation. Call (561) 928-0302 and we’ll look at it together.
Most roof replacements on PGT-equipped homes take 3 to 5 working days from tear-off to final inspection. Permitting in Mangonia Park can add 3 to 10 business days before we start, depending on the time of year. We handle the permit paperwork so you don’t have to figure out Palm Beach County’s requirements on your own.
No. The quote we give you is the price you pay unless you ask us to do additional work. If we find rotted decking, we show you the rot before we touch it and you approve the extra sheets at the per-sheet price already listed in your quote. No surprises on the invoice, ever.
Call (561) 928-0302 to schedule your free estimate. Ed’s name is on the business, which means your roof is his responsibility long after we’ve packed up the truck.
