AfterFast, Reliable Roof Installation Across Ojus
Roof installation in Ojus runs $7,500 to $18,500 for a typical single-family home, depending on the roof’s footprint, slope, and how many old layers need to come off first. We’re Mercer Roofing, and we’ve been working on Ojus rooftops long enough to know that what gets installed here has to meet a standard most of Florida doesn’t face. Ojus sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone, which changes everything about the products, fasteners, and paperwork your roof requires. Call (743) 200-8347 and we’ll give you a written price before any work starts.
Key Takeaways
- Every roofing product installed in Ojus must carry a Miami-Dade Notice of Acceptance (NOA) – this is non-negotiable and code-enforced.
- Most Ojus homes are post-WWII concrete block (CBS) construction with flat or low-slope roofs, which affects tear-off and decking decisions.
- Salt-laden air near the Intracoastal corrodes flashing, drip edges, and fasteners faster than inland areas.
- Insurance-driven replacement, not storm damage, is the most common reason Ojus homeowners call us.
- Mercer Roofing sends every technician’s name and photo before the visit, and each one arrives badged and background-checked under the Threshold Verified standard.
Why Mercer Roofing Is Ojus’s Preferred Roof Installation Company
Ojus homeowners call us because we speak the language of Miami-Dade code without making it sound like a seminar. Our Roof Installation crews know what a NOA-approved underlayment looks like, which fastener schedules the inspector checks, and how to document work so a Citizens Property Insurance renewal goes through without a fight. We’re not a truck that shows up from three counties away hoping to figure it out on your rooftop. We work Ojus regularly, and we know what these flat roofs and low-slope CBS homes hide under the old layers.
Every Mercer Roofing technician is background-checked, identity-verified, and dispatched under the Threshold Group quality framework. Before anyone steps onto your property, you’ll have that person’s name and photo. At the door, they’ll present a photo ID badge. That’s the Threshold Verified standard, and it’s the reason homeowners who’d otherwise hesitate to open the door choose us. Grant Whitlock leads our team with one rule: protect the person behind the door as much as the roof above it.
We answer the phone with a live person, 24/7. Not a callback form. When you call about a roof installation in Ojus, you get a human being who can schedule your free estimate and put a written price in your hands before any work begins.
Shingle Roof in Ojus
Shingle roof installation in Ojus means working with architectural asphalt shingles that carry a Miami-Dade NOA, typically rated for wind uplift pressures that inland Florida never has to consider. It’s the most common roof type we install on pitched sections of Ojus homes, and we use manufacturer-recognized brands including GAF, CertainTeed, and Atlas. A full shingle roof on a typical Ojus home runs $8,500 to $14,000 depending on square footage, the condition of the existing decking, and how many layers of old material need to come off first.
What a Shingle Install Includes Here
We strip the existing roof down to the deck, replace any water-damaged or deteriorated sheathing, and install a NOA-approved synthetic underlayment. In the valleys and around penetrations, we lay ice and water shield before the shingles go down. The fastener schedule matters in Ojus – Miami-Dade inspectors check nail patterns against the NOA, and we install to that standard from the first shingle, not as an afterthought.
When Ojus Homeowners Choose Shingles
Pitched roof sections, garage roofs, and additions on CBS homes are where shingles make the most sense in Ojus. They’re cost-effective, easy to repair if a branch comes down in a storm, and widely accepted by insurance carriers when properly documented with an NOA. If your existing shingle roof is 15 to 20 years old, your carrier may be sending letters – and that’s usually when we get the call.
Standing Seam Metal Roof in Ojus
Standing seam metal roof installation in Ojus is the strongest answer to this neighborhood’s specific storm and wind-load requirements. The interlocking panels resist uplift from hurricane-force winds better than almost any other system, and when installed with stainless steel fasteners rated for the High Velocity Hurricane Zone, they hold up against the salt-laden air that eats standard metal components within a decade. A standing seam metal roof on an Ojus home typically runs $14,000 to $22,000, with the final number driven by roof size, panel gauge, and how much decking work the old roof left behind.
Salt Air and Fastener Selection
This is where a cheap quote falls apart in Ojus. Standard galvanized fasteners and thin flashing corrode quickly a few miles from the Intracoastal. We install stainless fasteners, and we specify flashing and drip edge that can take the salt exposure without rusting through at the seams. The NOA documentation for a metal roof here matters too – your insurance carrier wants to see that every component, not just the panels, is approved for Miami-Dade.
What a Standing Seam Install Includes
We remove the old roof completely, inspect and repair the decking, install a NOA-approved high-temperature underlayment, then set the standing seam panels with a mechanically seamed or snap-lock profile depending on your roofline. Every penetration gets a metal-fabricated boot, not a rubber collar that the sun and salt degrade in a few seasons. The finished roof gets documented with the NOA paperwork your carrier will ask for.
Trusted Brands We Service in Ojus
We install and repair roofing systems from GAF, Atlas, and Tamko, and we stock the NOA-approved accessory lines those brands specify for Miami-Dade. That means when an Ojus homeowner needs a specific underlayment, a particular self-adhered membrane, or the right corrosion-resistant flashing, we aren’t waiting on a distributor in another county. Our Ojus customers get faster turnaround because the materials their roofs legally require are already on our racks. And because the work carries a manufacturer-recognized system, you’re not piecing together a roof from mismatched lines that a manufacturer will refuse to stand behind.
Common Roof Installation Problems We See in Ojus Homes
- Non-NOA products from out-of-county contractors. A roofer who works mostly in Broward County can legally install products across the county line that will never pass a Miami-Dade inspection in Ojus. We’ve torn off roofs here that were only a few years old because the underlayment didn’t carry an NOA, and the homeowner found out when an insurance inspection flagged it.
- Flat-roof membrane failures at flashings and penetrations. Ojus’s intense afternoon convective storms push driving rain sideways, and built-up or torch-down roofs that weren’t seated properly at the edges leak at the flashing points first. We see it constantly on the older CBS homes that dominate this area.
- Corroded drip edge and fasteners from salt air. Living within a few miles of the Intracoastal means metal components rust faster than the roof itself wears out. On a 1958 CBS home near NE 12th Avenue, our crew tore off three layers of torch-down modified bitumen and found the original drip edge and fasteners rusted through from decades of salt exposure. We replaced the damaged decking, installed a NOA-approved self-adhered underlayment and ice and water shield, and set a standing seam metal roof with stainless fasteners rated for HVHZ. The homeowner walked away with the NOA documentation and a roof-condition certification that kept their Citizens policy active.
- Decking rot hidden under multiple layers of old roofing. Because so many Ojus homes date from the late 1940s through the 1970s and have had multiple overlays added to the original built-up roof, the deck underneath is often compromised. We include deck repair in our quotes, not as a surprise change order, because we know what’s under these roofs before we start.
Pricing for Roof Installation in Ojus, FL
A shingle roof installation on a typical Ojus home runs $8,500 to $14,000. A standing seam metal roof runs $14,000 to $22,000. The final number depends on your roof’s square footage, the slope, how many old layers need removal, and how much decking has to be replaced once we get everything stripped. Ojus pricing runs about 12 to 18 percent higher than comparable work in Broward County because NOA-compliant materials cost more and the inspection process is stricter. What you’re paying for is a roof that actually passes inspection and satisfies your insurance carrier. Every Mercer Roofing quote is written, and no work starts until you’ve seen it.

FAQs About Roof Installation in Ojus
Because Ojus sits entirely inside Miami-Dade County’s High Velocity Hurricane Zone, every roofing product installed here must carry a Miami-Dade Notice of Acceptance. A Broward approval is not sufficient, and any contractor who tells you otherwise is setting you up for a failed inspection and a denied insurance claim. Call (743) 200-8347 and we’ll show you the NOA paperwork for every product in your quote.
Miami-Dade’s post-Andrew insurance market means carriers routinely drop or surcharge Ojus homeowners once a roof hits 15 to 20 years old, even when the roof shows no visible damage. The insurance company is not judging how the roof looks; they’re judging the statistical risk of a claim on an aging roof in a hurricane zone. We’ve helped many Ojus homeowners get a roof-condition certification and replacement documentation that kept their Citizens policy active. The best move is to call us before the cancellation letter arrives.
Salt-laden air from the Intracoastal and the Atlantic accelerates corrosion on metal flashing, drip edges, and fasteners. A roof that would last 25 years inland may start showing rust at the metal components within 10 years a few miles from the water. That’s why we specify stainless fasteners and corrosion-resistant drip edge on Ojus installs, and why those components appear in the written quote instead of a cheaper alternative that will fail early. Call (743) 200-8347 for an exact quote on your home.
A compliant Ojus quote includes NOA-approved underlayment, the correct fastener schedule for the HVHZ, corrosion-resistant flashing and drip edge, deck repair, and the documentation your insurance carrier needs. A cheap quote might omit NOA-compliant materials, use standard galvanized fasteners, skip the underlayment replacement, or fail to include deck evaluation. Those omissions don’t make the roof cheaper – they defer the cost until an inspection fails or a carrier drops you. Every Mercer Roofing quote is written and includes everything the job requires.
Yes. Architectural shingles from manufacturers like GAF and Atlas carry NOA approvals and can meet HVHZ wind requirements when installed with the correct underlayment and fastener schedule. We install architectural shingles regularly on Ojus homes and provide the documentation your carrier will request. Call (743) 200-8347 for a free estimate on a shingle roof that passes Miami-Dade inspection the first time.
