Why Mercer Roofing Co Orlando Is Fern Park’s Preferred Roof Installation Company
Fern Park homeowners keep calling us for one reason that has nothing to do with shingles: they know who’s coming to the door. Before any technician arrives, you get their name and photo sent to you. When they ring the bell, they’re in a clean uniform with a photo ID badge. Every tech is background-checked and identity-verified under the Threshold Verified standard, held by every independently owned Threshold Group location since 2000. If you’re home alone with kids, or you’re an older homeowner who doesn’t love the idea of a stranger walking the property, that badge at the door is the whole point.
Our work in Fern Park is backed by the 365-Day Done Right Promise. If the roof isn’t right within a year, we come back and make it right. No fine print, no arguing. We also put a written guarantee on every installation, and the written price you approve before we start is the price you pay at the end. Grant Whitlock leads our team, and he’s built the whole operation around one rule: treat every Fern Park home like someone’s going to be standing at the window watching us work. Because they usually are.
Styles & brands we work with






TPO Roofing Installation in Fern Park
TPO Roofing Installation in Fern Park is a common job because so many of the original ranches here have flat or nearly flat sections over enclosed carports, Florida rooms, and additions. TPO is a heat-welded single-ply membrane that reflects heat well, which matters on a Fern Park roof that gets hammered by the afternoon sun from April through October. A straightforward TPO replacement over a carport or small flat section in Fern Park typically runs $4,500 to $7,500 depending on square footage and decking condition.
How TPO Handles Fern Park’s Ponding Problem
Low-slope roofs in Fern Park pond water after heavy summer storms, and ponding is what kills flat roofing faster than anything else. TPO seams are heat-welded, so they resist the standing water that tears apart older modified bitumen and built-up roofs. When we install TPO on a Fern Park ranch, we also check slope and add tapered insulation where water tends to sit.
Roof-to-Wall Flashing on Enclosed Carports
Nearly every enclosed carport in Fern Park has the same hidden issue: the original roof-to-wall flashing was never tied into the home’s main drainage plane. When we install new TPO, we cut back the drywall or stucco at that transition, install proper step flashing and counterflashing, and only then lay the new membrane. Skipping that step means the new roof leaks into the wall within a year or two.
Shingle Roof in Fern Park
A Shingle Roof in Fern Park is the standard choice for the pitched sections of mid-century ranches and split-levels, where architectural shingles shed rain quickly and hold up to the intense UV exposure that breaks down cheaper 3-tab products. A full tear-off and shingle replacement on a typical 1,400 to 1,800 square foot Fern Park ranch usually lands between $9,500 and $14,500, and the job includes new underlayment, flashing, and ridge vent.
Architectural Shingles on Older Ranch Framing
Fern Park homes built in the 1950s and 1960s often have 2×4 rafters that were fine for the original lightweight shingles but deflect under the weight of modern architectural shingles. Before we lay anything, we check the framing at the eaves and ridge. If the rafters are undersized or the decking has rotted at the low edges, we price the reinforcement before the first nail goes in so you never get surprised mid-job.
Decking Replacement and Code Upgrades
Replacing a roof on a 1950s Fern Park home almost always triggers a code-mandated decking upgrade. Older homes often have 3/8-inch plywood or skip sheathing that doesn’t meet current nailing requirements for high-wind zones. We inspect every sheet, mark the rotted or undersized sections, and give you a written per-sheet price for replacement before we order materials.
Trusted Brands We Service in Fern Park
We install and service shingle and membrane systems from CertainTeed, Owens Corning, and IKO, among other manufacturer-recognized brands. That matters for Fern Park homeowners because a manufacturer warranty is only as good as the installer’s certification, and we do the work to the spec those manufacturers require. We keep common parts for these systems in our local supply chain, so if you need a section of CertainTeed Landmark or an Owens Corning Duration bundle matched after a storm, we can turn that around fast. If we see a product failing repeatedly in Fern Park’s specific conditions – high heat, heavy afternoon rain, oak leaf debris – we’ll tell you before you spend money on it.

AfterCommon Roof Installation Problems We See in Fern Park Homes
- Clogged scupper drains on flat carport roofs: Oak leaves and pine needles pile up in the scuppers, backing water up against the wall and into the top plate. We clear and re-flash every drain as part of a TPO or flat replacement.
- Undersized 2×4 rafters on original additions: Older enclosed porches and carports were built light, and modern shingle weight causes visible deflection. We inspect and reinforce these sections rather than shingling over a structural problem.
- Holes left from old HVAC and swamp cooler mounts: Decades of rooftop equipment replacements leave unflashed penetrations that leak slowly into the ceiling. We close and flash every one during installation.
- Valley flashing pulled away from the underlayment: On Fern Park’s many L-shaped ranches and split-levels, the valley intersections collect debris and the flashing separates over time. We replace valley metal and underlayment before the new shingles go on.

FAQs About Roof Installation in Fern Park
On most Fern Park ranches, that original built-up or modified bitumen roof over the carport is at the end of its life and gets replaced with a fully adhered TPO system. We also re-flash the roof-to-wall transition, which on older Fern Park homes was often never properly tied into the house’s main drainage plane. The scupper drains get cleared and re-sleeved so oak leaves can’t back water up against the wall. We price all of this in writing before we start, so the carport isn’t a surprise line item. Call (850) 757-3564 for an exact quote on your specific roof.
The afternoon storms from June through September dump intense rain in 20 to 40 minutes, which overwhelms the flat and low-slope sections on older Fern Park ranches. Water ponds on the nearly flat roof, and if the scupper drains are clogged with oak leaves, the water backs up against the wall flashing and finds a seam. The original built-up roofs on these homes were never designed for that volume of standing water, and the seams fail at the low points exactly where water sits. If you’re seeing leaks after storms, we can inspect and tell you whether it’s a repair or the roof is done. Estimates are free.
Yes, a permit is required for any full roof replacement in Fern Park, and once a permit is pulled, the inspection will likely require decking upgrades on a 1950s home. Many original Fern Park ranches have 3/8-inch plywood or skip sheathing that doesn’t meet current high-wind nailing requirements, so the inspector will flag it. We handle the permit, the inspections, and any code-required upgrades, and we price those upgrades into your estimate before work starts. You’ll know exactly what the permit triggers before we commit to anything.
You can keep the decking only where it’s structurally sound and meets current code for nail-holding and thickness. On many original Fern Park ranches, the decking is 3/8-inch or thinner, water-damaged at the eaves, or rotted around the low edges where water ponds. We replace the bad sheets and keep the good ones – and we show you exactly which sheets we’re replacing and what each one costs, in writing, before we order materials. Nobody should tell you “we’ll see once we tear it off” and leave you holding a bill. Got a Fern Park roof with questionable decking? Call us at (850) 757-3564 and we’ll walk the roof first.
Fern Park’s heat index and intense UV exposure break down the asphalt compounds and granule adhesion in shingles faster than you’d see in a drier climate, so we typically advise 30-year architectural shingles rather than cheaper 3-tab products that start curling within a decade here. The summer humidity also keeps roof surfaces damp longer after rain, which accelerates algae growth on north-facing slopes under oak canopy. The shingle brands we install – CertainTeed, Owens Corning, IKO, and others – all have formulations designed for high-heat, high-humidity environments, and we match the product to the specific exposure on your Fern Park house.
