What Does Metal Roofing Cost and Involve in Ojus?
Ojus Roofing typically runs $15,000-$40,000 for a full installation, with most residential jobs wrapping in 5-10 business days once materials arrive. Every panel and fastener must carry a Miami-Dade Notice of Acceptance (NOA) to comply with the High-Velocity Hurricane Zone.

How We Install a Metal Roof - Start to Finish
We break every metal roofing job into five clear stages so you know what’s happening and when you need to make decisions. Here’s how it works for a typical Ojus service area home.
Stage 1: Site assessment and structural verification (1 day)
We walk the roof, check the existing deck and framing, and verify whether your home’s structure can handle metal’s weight and wind-load demands. On the 1950s-1970s concrete-block ranches common in Ojus, we often find original built-up roofing over plank decking that needs reinforcement or full replacement. You’ll decide at this stage whether to strip to the deck or overlay, and whether to upgrade insulation while the roof is open. We pull preliminary measurements and photograph every penetration - vents, HVAC curbs, skylight wells - so the material order is exact.
Stage 2: Material selection and permit filing (3-10 business days)
This is where you choose your panel profile, substrate, and finish. We order only after you’ve signed off, since NOA-compliant metal panels are job-specific and non-returnable. While materials are fabricated, we file your permit through Miami-Dade County’s unincorporated office - not a city building department, because Ojus has none. County plan review for metal roofing typically takes 3-5 business days if the NOA documentation is complete; we’ve seen out-of-area contractors lose two weeks here because they submitted state-approved products that lack the county-specific certification.
Stage 3: Tear-off and deck prep (1-2 days)
We remove the existing roof system down to the deck, or to the substrate you’ve agreed on. Any rotted decking gets replaced. We install a high-temp underlayment rated for metal’s thermal conductivity, then apply sealants and flashing at all transitions. In Ojus, we pay particular attention to the low-slope sections common on mid-century ranches - these need extra waterproofing detail because standing water after heavy rains will find any gap.
Stage 4: Panel installation and fastening (2-4 days)
Crews arrive with your panels pre-cut to length. We install from eave to ridge, using the clip-and-fastener pattern specified in the product’s NOA - never generic screws, never field-drilled holes that void the wind warranty. Penetrations get custom flashings. You’ll want to be available on day one of this stage in case we find hidden damage or need to adjust a chimney or vent location.
Stage 5: Inspection and close-out (1 day)
Miami-Dade County inspects for proper fastening pattern, flashing detail, and NOA label verification on the materials. We don’t collect final payment until the inspection passes and you have your certificate of completion. Most Ojus jobs clear inspection on the first visit because we build to the NOA exactly, not to “how we’ve always done it.”
The Metal Roofing Options You’ll Choose Between
Roofing isn’t one product. Here are the decisions that actually change how your roof performs and what you pay.
- Standing seam vs. screw-through panels: Standing seam hides fasteners under vertical ribs - cleaner look, better wind resistance, 30-40% more cost. Screw-through panels (often called R-panel or 5V-crimp) expose fasteners and run 15-25% less, but the screws need re-torquing after the first few Miami heat cycles. For Ojus’s HVHZ exposure, we typically recommend standing seam on primary residences and screw-through only on detached workshops or carports where budget drives the decision.
- Substrate: Galvalume vs. aluminum vs. copper: Galvalume steel (zinc-aluminum coated) is the standard for Florida - strong, cost-effective, 40+ year lifespan if the coating isn’t scratched during install. Aluminum costs 20-30% more but won’t rust at cut edges, which matters if your roof has complex valleys or dormers. Copper is available but rare in Ojus; it’s triple the cost and develops a patina that not every HOA accepts.
- Finish: Kynar 500 vs. SMP polyester: Kynar 500 (PVDF) holds color for 30 years in South Florida UV and resists salt-air corrosion. SMP polyester fades faster and chalks, but costs 10-15% less. We default to Kynar on every Ojus job because the coastal exposure justifies it.
- Profile height: 1-inch seam height handles most residential wind loads. We spec 1.5-inch or 2-inch seams for homes with direct Biscayne Bay exposure or where the roof pitch is shallow enough to catch uplift.
- Insulation and thermal break: Metal conducts heat. We install a thermal break and reflective insulation during tear-off, which adds $800-$2,200 depending on roof size but drops attic temperatures 15-25 degrees. Most Ojus homeowners choose this once they understand the cooling-load impact.
What Metal Roofing Costs in Ojus, FL
Metal roof installation in Ojus ranges from $15,000 to $40,000, with most single-family homes landing between $22,000 and $32,000. Here’s what moves you through that range.
| Cost Factor | Low-End Impact | High-End Impact |
|---|---|---|
| Roof size and complexity | 1,200 sq ft, simple gable | 3,000+ sq ft, multiple hips/valleys |
| Existing roof condition | Single layer, sound deck | Multiple layers, rotted decking, structural repair |
| Material grade | Screw-through galvalume, SMP finish | Standing seam aluminum, Kynar 500, high-profile seam |
| Penetrations and details | Standard vents, no skylights | Skylights, chimneys, HVAC curbs requiring custom flashings |
| Insulation and ventilation upgrades | Basic underlayment | Full thermal break, ridge vent conversion, soffit vents |
Our written estimates include tear-off, disposal, deck repair up to 10% of surface area, underlayment, panels, fasteners, standard flashings, permit fees, and inspection scheduling. What typically isn’t included: structural truss repair, skylight replacement, gutter removal and reinstallation, and any electrical or HVAC relocation. We flag these possibilities during assessment so you’re not surprised.
What Ojus Homes Specifically Do to This Job
Ojus is unincorporated Miami-Dade County, which means no city building department exists to interpret your permit. Everything routes through the county’s central system, and the inspectors who sign off on your metal roof are the same ones working Aventura, North Miami Beach, and Sunny Isles Beach - a much broader territory than most contractors realize. We’ve seen crews from Broward County assume they can use the same products and methods that passed in Hallandale Beach, only to fail inspection because those materials lack the Miami-Dade NOA required inside the HVHZ.
The housing stock here is specific too: concrete-block ranches from the 1950s through 1970s, many with original flat or low-slope built-up roofs that have been patched repeatedly. When we strip these, we often find plank decking that’s never seen proper ventilation, and rafters spaced wider than modern code allows. Metal roofing on these structures demands careful load calculation and often supplemental framing - not because metal is heavy, but because the wind uplift forces in HVHZ are, and the original builders didn’t design for them.
Moisture is the other Ojus factor. The shallow water table and porous Miami Limestone beneath these homes mean any roof leak reaches interior fast. We see more ceiling damage from slow drips here than in areas with deeper drainage, which is why we spec full ice-and-water shield at valleys and penetrations even though Ojus never freezes. The limestone doesn’t absorb runoff; it channels it sideways. Your roof has to be the complete barrier.

Frequently Asked - Metal Roofing in Ojus
Most residential metal roofing jobs in Ojus take 5-10 business days of actual construction, plus 3-10 days for permit approval and material lead time. Call (844) 665-0162 and we’ll check current material availability for your specific panel choice.
Yes. Because Ojus is unincorporated Miami-Dade County, your permit pulls through the county Building Department, not a city office. The permit covers structural load, wind resistance, and NOA verification. We handle filing, fees, and inspection scheduling as part of our project management.
Existing gutters usually need removal and reinstallation because metal roofing adds thickness and changes drip-edge geometry. Ojus Sliding & Patio Doors and skylights can stay if they’re in good condition and properly flashed to the new panel system, but we recommend replacing units over 15 years old while the roof is open. We’ll assess both during your estimate.
Not when installed with proper underlayment and attic insulation. The thermal break and insulation package we spec for Ojus homes absorbs impact noise effectively. In 15 years of South Florida installs, we’ve had zero callbacks for noise complaints.
Material warranties run 20-40 years depending on the substrate and finish manufacturer. We work with GAF, CertainTeed, Owens Corning, and other roofing partners whose metal products carry specific NOA-backed wind warranties for HVHZ. Our workmanship warranty covers installation defects for the period specified in your contract. We’ll review both warranties line by line before you sign.
