Fast, Reliable Roof Replacement Across Ojus
Roof replacement in Ojus, FL typically runs between $9,500 and $26,000 for a full tear-off and re-roof on a mid-century CBS home, with flat built-up systems falling on the higher end due to multi-layer tear-off work. Most Ojus homes need permits pulled exclusively through Miami-Dade County’s building department, and every product installed must carry a Miami-Dade County Notice of Acceptance (NOA) because the community sits in the High Velocity Hurricane Zone. Our crews know the county’s inspection workflow, which means fewer delays between tear-off and final sign-off. Call (945) 303-9821 for a free written estimate on your Ojus roof replacement.
Why Tilehurst Roofing Is Ojus’s Preferred Roof Replacement Company
We’ve worked enough Ojus homes off NE 21st Avenue and around the Oleta River corridor to know exactly what gets uncovered when you peel back a roof that’s been patched since the Johnson administration. Homeowners around Ojus consistently tell us the same thing: other contractors no-showed for the estimate, pushed a cash deal at the door, or pulled permits through the wrong jurisdiction and left the job stalled for weeks. That’s precisely who we’re built for. Every Ojus roof replacement starts with a written price in your hands before a single nail is driven, and every job is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right for a full year after the job. Greg Holloway, who runs this location, insists on background-checked, uniformed technicians on every Ojus job so you know exactly who’s on your roof. When you call, a live person answers. Not voicemail. Not a callback queue. 24 hours a day, including evenings and weekends.
Reroofing in Ojus
Reroofing in Ojus means stripping one or more existing roof layers down to the decking and installing a new NOA-compliant system, because most homes here carry the original mid-century built-up roof plus one or two patch-over layers from the 1980s and 1990s. A homeowner needs reroofing, rather than another patch, when the existing roof has multiple active leaks, visible ponding after storms, or organic growth pushing through membrane seams. In Ojus, a full reroof on a typical 1,400 to 1,900 square foot CBS ranch runs $11,000 to $22,000 depending on how many layers come off and whether decking replacement is required. The tear-off phase on Ojus homes almost always takes longer than a newer-build tear-off because those extra layers were often nailed directly over failed membrane and rotted plywood.
County Permit and NOA Compliance
Every reroof in Ojus pulls its permit through Miami-Dade County’s unincorporated building department, not through a city hall. That means the inspector reviewing your job is applying HVHZ wind-load standards, the same code used for high-rise coastal construction. Out-of-area roofers who normally work in North Miami Beach or Aventura often misjudge the county’s queue times and re-inspection rules, which adds days or weeks to a job that should have been straightforward.
Mid-Century Tear-Off Reality
On a 1968 CBS home near the Oleta River, we were called in after the homeowner had been patching a flat built-up roof for years. The tear-off revealed three layers of old roofing over delaminated plywood decking and corroded metal flashing around the AC curb. This is the Ojus scenario we plan for: layered tear-off, deck replacement, and a new low-slope system staged over NOA-approved panels, all inspected by the county before we call the job done.
Flat Roof Replacement in Ojus
Flat roof replacement in Ojus usually means removing a built-up system of gravel and hot asphalt, or a failed modified bitumen membrane, from a 1950s to 1970s CBS home and installing a modern low-slope system engineered to shed water rather than hold it. Ojus homeowners need flat roof replacement when ponding water persists for more than 48 hours after a storm, when ceiling stains appear repeatedly under the same low spots, or when membrane seams have opened from years of thermal movement. Flat roof replacement in Ojus typically runs $13,000 to $26,000, driven by tear-off layers, decking condition, and the need to rebuild wooden crickets and scuppers to meet current drainage standards.
Ponding and Drainage Correction
Mid-century Ojus rooflines were never engineered to the slope or scupper standards required today. Intense summer convective storms dump inches of water in an hour, and flat sections hold that water until it evaporates, saturating membrane seams and eventually failing them. A properly staged flat roof replacement adds tapered insulation or sloped decking so water moves to scuppers instead of sitting there.
Salt Air and Fastener Corrosion
Ojus sits close enough to Biscayne Bay that salt-laden air accelerates rust on metal flashing and fasteners faster than communities just a few miles inland. We replace corroded flashing around AC equipment curbs, plumbing penetrations, and parapet walls with corrosion-resistant materials as part of every flat roof replacement, because those are the failure points that send water inside long before the membrane itself gives out.
Trusted Brands We Service in Ojus
We install full roof systems from three manufacturers that hold strong local reputations in South Florida’s hurricane market: GAF, Boral, and Atlas. Every product we pull for an Ojus job carries a current Miami-Dade County NOA, which is non-negotiable here because HVHZ inspectors check product approvals against the county registry. We stock common flashing, underlayment, and ridge components matched to these brands so the crew isn’t waiting on a regional supplier run when your tear-off reveals a surprise mid-job. The product fits the home and the code. Not just whatever happened to be on the truck that morning.
Common Roof Replacement Problems We See in Ojus Homes
- Ponding water on flat sections after summer storms. Mid-century Ojus rooflines lack the slope modern drainage standards require. Water sits, membrane seams fail, and the leak that finally gets noticed is usually weeks older than the stain on the ceiling.
- Corroded flashing around AC curbs and plumbing penetrations. Salt air off Biscayne Bay eats galvanized metal faster here than inland. We routinely find flashing so rusted it crumbles when touched during tear-off.
- Multiple layers of hidden roofing over compromised decking. Ojus homes built from the early 1950s through the late 1970s were often re-roofed over old systems rather than torn off. We’ve pulled as many as three layers off a single Ojus flat roof, with delaminated plywood underneath.
- Permit confusion in unincorporated county territory. Homeowners who assume their roof is permitted through a city building department get stalled when the county’s HVHZ rules apply instead. Knowing the county workflow is the difference between a roof done in two weeks and one stuck in re-inspection for two months.
Pricing for Roof Replacement in Ojus, FL
A full roof replacement on a typical Ojus CBS ranch runs $9,500 to $26,000. Reroofing with architectural shingles on a pitched section lands around $11,000 to $18,000, while flat built-up replacements run $13,000 to $26,000 because they usually involve multi-layer tear-off and drainage correction. What moves the number in Ojus specifically: how many layers come off, whether decking replacement is triggered by rot or delamination, and whether HVHZ re-inspection requires additional structural upgrades once the roof is open. We put the price in writing before any work starts, and any change triggered by hidden conditions gets priced and approved in writing before we touch it.

FAQs About Roof Replacement in Ojus
Ojus is an unincorporated Miami-Dade County community, so it has no city building department of its own. Every roof replacement permit runs through Miami-Dade County’s building system, which applies High Velocity Hurricane Zone code, the strictest in the U.S. This means all products must carry a county Notice of Acceptance, and inspectors enforce HVHZ wind-load and installation standards. Call (945) 303-9821 and we’ll walk you through the permit path before any work starts.
Two or three layers is common on Ojus homes built between the early 1950s and late 1970s. Many original built-up roofs were patched and re-covered rather than torn off, which is why tear-off on an Ojus flat roof takes longer and costs more than on a newer home. We’ll price the tear-off for what’s visibly there and write a clear allowance for what gets uncovered after the first layer comes off. Call (945) 303-9821 for a free estimate with the tear-off scope in writing.
Mid-century Ojus rooflines were built nearly flat without the slope or scupper sizing modern drainage standards require, so intense South Florida convective storms leave standing water that saturates membrane seams. Yes, a new roof can fix it by adding tapered insulation or sloped decking so water moves to scuppers instead of pooling. This is a standard part of how we stage flat roof replacements in Ojus. Call (945) 303-9821 to get your drainage correction priced in writing.
Yes, and it’s measurable. Ojus sits near the Oleta River watershed and Biscayne Bay, and salt-laden air corrodes galvanized metal flashing and fasteners noticeably faster than inland communities. We routinely replace rusted flashing around AC curbs, plumbing penetrations, and parapet walls during Ojus tear-offs because those corroded points are where leaks begin long before the membrane fails. Call (945) 303-9821 for a free inspection of your flashing condition.
We stop, document what we found, and bring you a written price for the additional scope before we touch anything. Decking damage from layered tear-off rot or delamination is common in Ojus’s vintage housing stock, and when the county re-inspects mid-project, additional HVHZ upgrades may be required. You’ll never get a surprise bill after the fact, because nothing extra gets installed until you’ve approved the number in writing. Call (945) 303-9821 for a free written estimate that includes a clearly scoped decking allowance.
