CGI Roof Replacement & Installation in Mangonia Park: What to Know First
CGI roof replacement and installation in Mangonia Park typically runs $9,800 to $34,000 depending on roof size, material choice, and decking condition, with most full tear-offs completed in 2 to 5 working days. We’re an independent CGI service provider, not a manufacturer affiliate, which means we choose the best fixing method for your home without brand politics. If your CGI roof is leaking, lifting, or showing age, call (561) 928-0302 and a real person answers.
This page is for Mangonia Park homeowners who own a CGI roof system or are considering one for a replacement. Ed Winslow’s name is on the business, and he’s been roofing in Palm Beach County since before half the subdivisions off Australian Avenue were built. We’ll walk through what fails, what it costs, and what we do differently.
How CGI Products Fail and How We Fix Them
CGI builds strong roofing systems, but Mangonia Park’s heat, salt air, and summer downpours expose every weak point. Here’s what we see most often:
- CGI metal roof seam separation after thermal cycling. CGI standing-seam panels expand and contract with Mangonia Park’s 30-degree daily temperature swings. Over a decade, the fasteners at panel laps work loose, and water creeps under the seam. We remove the affected panel, inspect the underlayment, re-seat seams with the correct OEM clips, and re-torque to spec.
- CGI tile roof underlayment failure from trapped moisture. South Florida humidity doesn’t just sit on top of the roof; it works up from the attic side. CGI concrete and clay tile installations fail from the bottom when underlayment was installed over damp decking. We strip tiles, dry the deck, replace underlayment with a modern synthetic rated for 130+ mph uplift, and reset tiles in a staggered bond.
- CGI shingle granule loss on western-facing slopes. Homes along 45th Street and Australian Avenue get brutal afternoon sun. CGI’s asphalt shingle line loses granules faster on west exposures, and when granules go, the mat beneath starts degrading. We replace those slopes with impact-resistant CGI shingles and inspect the rest of the roof for early-stage cracking.
- CGI flashing failures at parapet walls and skylights. Any Mangonia Park home with a flat or low-slope section has parapet flashing, and that’s where CGI systems leak first. The original flashing gets brittle from UV exposure, and the sealant breaks down. We fabricate new flashing on-site, re-bed it in polyurethane sealant, and run a water test before we pack up.
- CGI panel or tile damage from falling palm debris. Mangonia Park’s mature sabal palms drop fronds heavy enough to crack tile corners or dent metal panels. We insist on decking inspection under any cracked area, because water stains often travel further than the visible damage.
Our CGI Roof Replacement & Installation Process
Here’s how a CGI roof job goes when you call Winslow Windows & Doors:
- 1
The call. You dial (561) 928-0302. Ed or a member of the team answers live, no call center. We ask what you’re seeing, when it started, and get a sense of urgency.
- 2
The inspection. We come to your Mangonia Park home, walk the roof, document everything with photos, and check the attic. You get a written report with exact findings, not a summary over the phone.
- 3
The parts decision. For anything structural or warranty-critical, we use OEM CGI components. For non-structural items like sealant, fasteners, or underlayment, we use tested aftermarket materials that match or exceed spec. We explain every choice so you can check it yourself.
- 4
The work. Background-checked, uniformed technicians arrive on the scheduled day. We protect your landscaping, strip the old system, repair or replace decking, install the new CGI roof with the right underlayment and flashing, and clean up the same day.
- 5
The test. We hose-test flashings and low-slope areas, walk the final installation with you, and hand you the job sheet.
- 6
The guarantee. Every CGI roof we install carries our workmanship warranty plus the Done Right Promise. If it’s not right, we come back. That’s not a slogan; it’s the standard Ed set when he put his name on the truck.
What CGI Roof Replacement & Installation Costs in Mangonia Park
CGI roof replacement in Mangonia Park is priced per square (100 square feet) and depends on the material line, tear-off needs, and decking condition. Here’s a realistic breakdown for typical Palm Beach County homes:
- CGI asphalt shingle roof: $9,800 to $16,500 for a 1,500-2,200 sq ft home, tear-off and haul-away included.
- CGI standing-seam metal roof: $18,000 to $34,000 depending on panel gauge, seam type, and roof complexity.
- CGI concrete or clay tile roof: $16,500 to $29,000 including underlayment replacement, which is mandatory for any tile reset in Mangonia Park.
- Decking replacement (if rotten): Add $2.50 to $5.25 per square foot of damaged area.
What moves the price? Roof slope and access, number of penetrations like skylights and vents, and whether the existing decking passes inspection. We give you a fixed line-item estimate before we start, and the price we quote is the price you pay. No change orders sneaking in at the end of the job.

Why Mangonia Park Homeowners Call Winslow Windows & Doors for CGI Work
A lot of roofing companies will install CGI products. Few know the material the way we do, and fewer still operate like we do. Ed has been installing impact-rated exterior systems since 2011, and CGI roofs are a big part of that. When a CGI roof leaks, we don’t guess; we diagnose the actual cause and explain it in plain English before we ever put a ladder against your wall.
The difference is accountability. The Done Right Promise means if we don’t do it right, we make it right, no argument. We answer calls live, 24/7, because roofing problems in Mangonia Park don’t wait for business hours. And because we’re independent, we don’t push you toward the one brand we’re incentivized to sell. If a PGT, CWS, ES Windows, or ECO Window Systems component is the right fit for your home’s openings while we’re doing a full exterior, we’ll tell you that. Most Mangonia Park homeowners just call us because we’re the one down the road, with a published address and a license number you can verify.
FAQs
No, as long as the installation uses CGI-approved components and follows the manufacturer’s installation guidelines, your CGI material warranty remains intact. That’s why we use OEM CGI parts for anything structural and document every step of the job. If you ever need to file a manufacturer claim, you’ll have the paper trail.
Most CGI roof replacements take 2 to 5 working days from tear-off to final inspection, depending on roof size, material type, and how much decking needs repair. Weather is the wild card; a week of afternoon thunderstorms will stretch the timeline. We’ll give you a schedule before we start and call you the night before each workday. Call (561) 928-0302 for a timeline specific to your roof.
In many cases, yes, if the damage is localized and the underlying decking is still solid. We’ll always show you photos and give you an honest repair-versus-replace recommendation. When a repair makes sense, we do it and warrant the work. When it doesn’t, we’ll tell you that too, and explain exactly why replacement is the better long-term decision for your Mangonia Park home.
