AfterFast, Reliable Roof Installation Across Westgate
A new roof on a Westgate home is rarely a simple swap. Most of the houses here were built between 1950 and 1975 as concrete block, single-story CBS structures with flat or very low-slope roofs. Those roofs now sit squarely in Palm Beach County’s hurricane corridor, and any permitted replacement has to meet current wind-mitigation code. Mercer Roofing handles the full scope: structural inspection coordination, deck fastening upgrades, hurricane-strap retrofits, and installation of a membrane or shingle system that passes inspection and earns the insurance credit. Call (743) 200-8347 for a free, written estimate.
Why Mercer Roofing Is Westgate’s Preferred Roof Installation Company
Westgate is its own place, with its own permit path and its own set of roof problems. Palm Beach County Building Division, not a city hall, reviews every Westgate re-roof permit, and they enforce wind-mitigation details that homeowners in incorporated cities like West Palm Beach or Lake Worth often never see. We know those details because we work them every week. Our Roof Installation crews understand what a 1960s CBS parapet wall does after sixty years of South Florida rain, and we write quotes that include what the inspector will actually require, not just what makes the number look low.
Every one of our technicians is background-checked and identity-verified under the Threshold Standard. Before a technician arrives at your Westgate door, you receive their name and photo. They arrive in a marked uniform with a photo ID badge. That standard applies to every visit, no exceptions. Our clients across Westgate tell us that one detail is why they chose us over the lower quote. Founded in 2000 and part of the Threshold Group family, we answer the phone with a live person 24/7. Grant Whitlock leads our team, and our 365-Day Done Right Promise covers the work: if it’s not right within a year, we make it right.
TPO Roofing Installation in Westgate
TPO Roofing Installation is the most common full replacement we perform on Westgate flat and low-slope CBS homes. TPO is a heat-welded single-ply membrane that reflects UV instead of absorbing it, which matters here where the sun punishes roofs year-round. A typical TPO installation on a Westgate home runs $8,500 – $14,000, depending on square footage and whether parapet nailers need rebuilding.
The job is more than rolling out a membrane. On most Westgate homes, we strip the old tar-and-gravel or modified bitumen layers down to the deck, then inspect what’s underneath. That inspection often reveals the real cost driver: rotted wood nailers along the parapet walls. We replace the decking, install new fasteners to the Palm Beach County wind-mitigation schedule, set the insulation and TPO membrane, and finish with new metal flashing and drip edge. The county’s structural inspection is part of the job, and we build the work to pass it.
When full TPO replacement beats another patch
Westgate roofs get patched for years. We see them with three or four accumulated membrane layers and tar repairs around every penetration. At some point the patch cycle stops being cheaper. If the underlying membrane is oxidized and cracking, if ponding water sits for days after a storm, or if a recent insurance inspection flagged the roof’s condition, full TPO replacement is usually the right financial move.
What a compliant TPO quote includes
A quote from us lists the deck fastening schedule, the hurricane-strap retrofit if required, the membrane thickness and brand, the insulation type, and the flashing scope. A cheap quote omits the structural items because the roofer doesn’t plan to do them. When the county inspector checks the roof and finds the deck wasn’t fastened to current code, the owner pays for a second tear-off. We quote for the job that passes the first time.
Shingle Roof in Westgate
Shingle Roof installation in Westgate is less common than TPO because so many of the homes carry flat or very low-slope decks, but a fair number have gable additions or were re-framed to pitched roofs over the years. For those homes, architectural shingle installation runs $9,000 – $16,000 depending on roof size, pitch, and deck condition.
We install GAF, Atlas, and Tamko architectural shingles in Westgate. These are rated for high wind, which matters here. The county requires a specific nail schedule and, on many Westgate homes, hurricane straps or clips connecting the rafters to the walls. We install the full system: synthetic underlayment, ice and water shield at the eaves and valleys, new flashing at every penetration, and ridge venting. The shingle is only the top layer. What’s under it determines whether the roof survives the next named storm.
Decking repair before the shingles go down
On Westgate homes with pitched sections added decades ago, the original decking is often thin plywood that’s softened from years of trapped moisture. Code requires solid decking before shingles can be fastened. We replace soft sheets, re-nail the entire deck to the wind-mitigation schedule, and document every step for the inspector.
Wind-rated shingle installation
Not every shingle on a Westgate home is installed to its wind rating. A shingle with a 130 mph rating only performs to that spec when the fastening pattern, starter strip, and underlayment are correct. We install to the manufacturer’s high-wind spec, because in this part of Palm Beach County the wind rating is the point of buying the shingle in the first place.
Trusted Brands We Service in Westgate
We install and repair roofs using manufacturer-recognized brands, including GAF, Atlas, and Tamko. These are the systems we trust on Westgate homes because their high-wind ratings hold up in a coastal environment where salt air and UV oxidation work against every component. We don’t stock every brand on every truck, but our supply chain reaches Westgate quickly, and we order materials to match the exact scope on your written quote. You’ll know the brand, the product line, and the wind rating before any material is ordered. No work starts without a written price.
Common Roof Installation Problems We See in Westgate Homes
- Ponding water on flat roofs. Westgate sits on a nearly zero-grade plain with no drainage relief. After a heavy wet-season downpour, water sits on flat membranes for days. It accelerates oxidation, finds the smallest seam gap, and slowly rots the wood nailers underneath. A proper installation builds in positive drainage slope and tapers insulation to move water off the roof instead of holding it.
- Rotted parapet nailers hiding under old membranes. On these CBS flats, the low slope traps rainwater against the parapet wall cap. Water wicks into the wood nailers for years without anyone seeing it. When the membrane comes off, the wood often crumbles. Palm Beach County’s structural inspection won’t pass a deck with rotted nailers, so the rebuild becomes mandatory. This is the single biggest cost surprise in Westgate roof replacement.
- Deck fastening that doesn’t meet current wind-mitigation code. Homes built before modern hurricane codes typically don’t have the deck nailed at the current fastening schedule. The county requires verification or upgrade as a condition of the permit. A quote that doesn’t include this work is quoting for a roof that won’t pass inspection.
- Salt-air corrosion on flashing and drip edge. Westgate sits just a few miles inland from the Atlantic. Salt in the air attacks metal flashing and drip edge faster than in central or north Florida. Undersized or unrated flashing fails years before the membrane or shingle warranty ends. We spec heavier-gauge, corrosion-resistant flashing on every Westgate job.
Pricing for Roof Installation in Westgate, FL
Flat-roof TPO replacement in Westgate runs $8,500 – $14,000 for a typical 1950s – 1970s CBS home. Shingle roof installation on pitched sections runs $9,000 – $16,000. The two biggest cost variables are square footage and what the tear-off reveals: rotted parapet nailers, compromised decking, or missing hurricane straps all add scope.

FAQs About Roof Installation in Westgate
Westgate is an unincorporated Palm Beach County CDP, so every permitted roof replacement runs through the Palm Beach County Building Division, not a city building department. That division enforces current wind-mitigation compliance, including deck fastening schedules and hurricane-strap retrofits, as a condition of the permit. Many of Westgate’s 1950s – 1970s CBS homes predate those codes, so the upgrade gets triggered on nearly every full re-roof. Incorporated neighbors like West Palm Beach and Lake Worth sometimes follow different permit tracks with different enforcement. Call (743) 200-8347 and we’ll walk you through what applies to your specific home.
Yes. On a permitted Westgate roof replacement, Palm Beach County requires a structural inspection after the old roof is stripped and any decking, nailer, or strapping upgrades are complete, before the new membrane gets set. That inspection checks the deck fastening, parapet condition, and hurricane-strap retrofit. We schedule the inspection, do the work to pass it, and document everything for your insurance file.
Look for three line items the cheap quote usually omits: deck fastening to the county wind-mitigation schedule, hurricane-strap or clip retrofits, and parapet nailer replacement. If those aren’t listed, ask whether the roofer plans to do them before inspection. If the answer is vague, you’re looking at a quote for a roof that won’t pass. Our written quote lists all three as applicable, plus brand, product, and wind rating. Call (743) 200-8347 for a free written estimate you can compare line by line.
Only when installed to the manufacturer’s high-wind specification. The shingle itself may be rated for 130 mph, but that rating depends on the correct nail schedule, starter strip placement, and underlayment. On a Westgate home in the Atlantic hurricane corridor, a shingle installed any other way won’t perform to its rating. We install to the high-wind spec because the wind rating is the only reason to choose an architectural shingle in this climate.
After a storm, the insurance adjuster asks for evidence that the roof met current wind-mitigation code. If the deck fastening wasn’t upgraded, the straps weren’t installed, and the inspection records don’t exist, the claim can be reduced or denied. We provide documentation of every structural upgrade and the passed inspection with each completed Westgate roof. That paperwork is part of the roof, and it’s part of what you’re paying for.
