AfterFast, Reliable Roof Installation Across Olympia Heights
Roof installation in Olympia Heights runs anywhere from $11,000 to $34,000 for a full tear-off and replacement, and most jobs take three to seven working days from tear-off to final county inspection. That range is wider here than in most of Florida because this part of Miami-Dade enforces the High Velocity Hurricane Zone code, which changes what materials can legally go on your roof and how many fasteners hold it down. Our crews know the Olympia Heights housing stock: dense streets of 1950s to 1970s CBS homes with flat and low-slope roofs, shared driveways, and county inspectors who need clear access to your curb. Call (743) 200-8347 and we’ll walk the roof with you, write the scope in plain English, and hand you a price before any work begins.
Why Mercer Roofing Is Olympia Heights’s Preferred Roof Installation Company
Mercer Roofing, a Roofing Company - Olympia Heights trusted by local homeowners, has worked on hundreds of Olympia Heights homes over the years, and the thing that keeps people calling is simple: our technicians send their name and photo before they arrive, then badge in at your front door with a photo ID. For a homeowner who is home alone, or a parent with young kids, that single step removes the biggest worry about a roof installation, which is the stranger in the driveway. We are part of the Threshold Group family, founded in 2000, and every technician is background-checked, identity-verified, and held to the Threshold Verified standard each independently owned location must meet.
Olympia Heights is a specific kind of job site. Most streets are lined with homes built between the early 1950s and late 1970s, and many still carry their original aggregate built-up roofs under one or two later cap sheets. We quote for what is actually up there, not what the paperwork says. When a tear-off on a 1962 CBS home off SW 24th Street near the Westchester edge revealed a 1990s torch-down cap hiding the original aggregate roof underneath, our crew knew exactly what that meant for disposal tonnage and scheduling on a street where parking fills early. We staged all tear-off debris inside one roll-off in the driveway and coordinated with the neighbor on the shared wall so the loudest work happened inside the county’s allowed hours. That is not a claim; that is how we run jobs here.
Roof Flashing Installation in Olympia Heights
Roof flashing installation in Olympia Heights means replacing the metal that seals the places where your flat roof meets a parapet wall, chimney, vent pipe, or the shared wall between two attached CBS homes, and it typically runs $600 to $2,800 depending on how many penetrations and linear feet are involved. Flashing on these older homes is often original, paper-thin, and corroded from decades of salt air and afternoon thunderstorms. When it fails, water gets behind the stucco and into the concrete deck, which is exactly the kind of slow damage that turns a $1,200 flashing job into a $9,000 deck repair.
Before any flashing goes down, our Roof Installation team checks what is underneath it. On HVHZ jobs, flashing has to meet Miami-Dade Notice of Acceptance requirements, which means the product itself must be approved for this wind zone and installed per the NOA’s fastening schedule. We do not reuse old flashing, even if it looks fine from the ground.
When Olympia Heights homeowners need new flashing
You need it when you see water staining on interior ceilings near a wall, when parapet caps are lifting, or when the sealant around vent pipes has dried and cracked. Homes with original built-up roofs from the 60s and 70s almost always need flashing work at the same time as a full tear-off, and it is cheaper to do it all in one mobilization than to pull it apart twice.
What flashing work costs with a tear-off
Bundled with a full roof installation in Olympia Heights, flashing replacement usually adds $800 to $2,200 to the job depending on how many curbs, walls, and pipes the roof has. We write that line item into the quote before work starts so the written price you approve is the price on your invoice.
TPO Roofing Installation in Olympia Heights
TPO roofing installation in Olympia Heights is the most common route we recommend for flat and low-slope CBS roofs, and a full tear-off plus new TPO membrane typically runs $13,000 to $27,000 for a 1,200 to 2,000 square foot home. TPO is a white, heat-reflective single-ply membrane that carries Miami-Dade NOA approvals, resists the UV degradation that shortens roof life in South Florida, and knocks down cooling costs on these older homes by reflecting sunlight that aggregate built-up roofs absorb.
A proper TPO installation here starts with a full tear-off to the concrete deck. We do not install over an existing roof, and in Olympia Heights that matters more than most places because an overlay hides what is underneath. Then we fix or replace spalled decking, lay the insulation and cover board, and mechanically attach or adhere the membrane per the manufacturer’s NOA. The seams are heat-welded, not glued, which is what gives TPO its strength against wind-driven rain.
Why flat roofs here need TPO, not shingles
Shingles need slope to shed water. Olympia Heights homes built in the 50s through 70s largely have flat or very low-slope roofs that pool water after a downpour. TPO is designed for standing water and high UV, which is why building codes in this HVHZ push flat-roof homeowners toward single-ply systems like TPO rather than shingle conversions that would require expensive re-framing.
What affects a TPO quote
The big variables are deck condition, insulation thickness, roof edge detail, and how many penetrations the roof has. A roof with five vent stacks and two parapet walls costs more in labor than a clean rectangle. We price it line by line and hand you the number before a single nail is driven.
Trusted Brands We Service in Olympia Heights
We install and service roofing systems from GAF, Atlas, and Tamko, and we keep local stock for the membrane and flashing systems most Olympia Heights homes use. That means when we find rotted decking or a failed parapet cap mid-job, we are not waiting a week on a distributor in Doral. Our relationship with these manufacturers also means the assemblies we install carry the Miami-Dade NOA documentation your county inspector will ask for. If you want a specific brand or system on your roof, say so at the estimate, and we will write that exact product into the quote.
Common Roof Installation Problems We See in Olympia Heights Homes
- Overlay-on-overlay roofs. Roofers in the 1980s and 90s often capped the original aggregate built-up roof with a torch-down layer instead of tearing it off. When we strip a cap sheet on a 1968 Olympia Heights home, the original roof is frequently still there underneath, which doubles disposal tonnage and can add $1,500 to $3,000 to a job that was quoted as a single-layer tear-off.
- Spalled and rotted concrete decks. Water that sat under an old membrane for years damages the concrete deck. A full tear-off frequently exposes deck sections that need patching or replacement before any HVHZ system can be installed, and that is a line item no honest roofer can price until the old roof is off.
- Access failures that stall county inspections. Miami-Dade inspectors can do drive-by checks on roof permits in Olympia Heights. If a shared driveway is blocked or the street is parked out, the inspection cannot happen, and the job sits. That is why we scope access before we quote, not after the dumpster arrives.
- Party-wall flashing failures. On attached CBS homes, the wall you share with a neighbor has flashing along its base that degrades with age. When it fails, water enters both homes. We coordinate with the neighbor, explain what we are doing and why, and replace that flashing as part of the installation so neither side inherits a leak later.
Pricing for Roof Installation in Olympia Heights, FL
Here are real Olympia Heights numbers. A full tear-off and re-roof on a 1,200 to 1,800 square foot flat-roof CBS home runs $11,000 to $22,000. A 2,000 to 3,000 square foot home runs $18,000 to $34,000. TPO systems land toward the middle and upper end; a modified bitumen system can come in slightly lower but carries a shorter service life in this UV environment. Roof flashing installation as a standalone job runs $600 to $2,800, and full TPO roofing installation runs $13,000 to $27,000 for typical Olympia Heights homes. Deck repairs, insulation replacement, and extra disposal tonnage from hidden overlay roofs are the three things that change a quote most. Every estimate we give is a written line-item price, and no work starts until you approve it. Call (743) 200-8347 for a free written estimate.

FAQs About Roof Installation in Olympia Heights
Miami-Dade County, not a city office. Olympia Heights is an unincorporated CDP, so roof permits are pulled through Miami-Dade County’s building department, and the inspector who signs off is a county inspector working under HVHZ rules. Every assembly on your roof has to carry a Miami-Dade Notice of Acceptance. We handle the permitting paperwork and schedule the inspection when the job is ready. Call (743) 200-8347 and we will walk you through what a permit costs for your specific roof.
Because what is under the top layer is not visible from above. Olympia Heights is full of 1950s – 1970s CBS homes that had overlay roofs done in the 80s and 90s, so a torch-down cap often conceals the original aggregate built-up roof beneath it. That doubles disposal tonnage, and tear-off frequently exposes spalled concrete decking that has to be repaired before any HVHZ system can be installed. We price honestly: the quote covers what we can see, and any change order is written and approved by you before we proceed. That written-price discipline is the whole point of how we work.
It can, and it should be figured into the quote, not discovered on day one. If a roof has no driveway space for a roll-off and the street parking fills early, material deliveries and debris removal require more handling, which costs labor. Shared driveways and party walls also add coordination time. We scope access during the estimate and price it honestly. That is why our written quotes for Olympia Heights homes sometimes look different from a quote for the same roof on a wide suburban lot in Pembroke Pines.
Any system carrying a current Miami-Dade Notice of Acceptance meets the legal requirement, which in practice means a single-ply membrane like TPO, a modified bitumen system, or a properly installed built-up roof. For most Olympia Heights homes, we recommend a TPO system from GAF, Atlas, or another NOA-approved manufacturer because it reflects UV, welds into a watertight monolithic layer, and holds up under standing water. Whatever system you choose, we install it exactly to the NOA fastening schedule so the county inspection passes cleanly.
We stage one roll-off in your driveway or the nearest legal spot, keep all tear-off debris inside it, and sweep for nails at the end of every day. On attached homes, we talk to the neighbor about the work before tear-off starts and run the loudest demolition inside the hours Miami-Dade County allows. Our technicians wear clean uniforms, show photo ID at the door, and send their name and photo ahead of the visit, so the people around you know exactly who is on the property and why.
