Owens Corning Roof Replacement in Miami: What to Know First
An Owens Corning roof replacement in Miami typically runs $8,400 to $18,600 for a standard single-family home, and the full job usually takes one to two days once materials arrive. We replace Owens Corning roofs of every configuration: full tear-offs, decking replacement, architectural shingle upgrades, and flat roof conversions. If you’re seeing granule loss in your gutters, curling shingles, or water staining on ceilings, call (850) 318-3769 for a written price before any work starts.
This page is for Miami homeowners who bought an Owens Corning roof and need to know what replacement actually involves here, where salt air, hurricane code, and afternoon downpours stress shingles differently than almost anywhere else in the country. Dylan Pace and the Crestview Roofing Co Miami team have replaced hundreds of Owens Corning systems across Miami, from Brickell condos to Kendale Lakes ranches, and the details below reflect what we actually see on the job, not what a brochure says.
How Owens Corning Products Fail – and How We Fix Them
- Duration Series granule shedding at the 8-year mark. The Duration line is a solid shingle, but in Miami’s UV index, the ceramic granules on south-facing slopes can start releasing around year eight or nine. You’ll see dark streaks in the gutter or a patchy “bald” look on the shingle face. That’s the fiberglass mat starting to show. Once granule loss is that visible, the shingle is no longer protecting the asphalt layer underneath. We don’t patch over this. We replace the affected slopes entirely, and if the north side is heading the same direction, we recommend a full replacement so you’re not paying for a second mobilization in three years.
- Oakridge lifting along the rake edge during wind events. Oakridge is a decent mid-tier line, but wind-driven rain in Miami finds it at the gable ends first. The sealant strip loses adhesion along the rake edge, the shingle lifts, and water rides the underlayment down into the soffit. We see this after every named storm, and the fix requires more than resealing. The correct repair is a full rake-edge rebuild with new starter course and a properly nailed drip edge. If the decking under the rake edge is soft, that section of plywood gets replaced before the new shingles go down. We document every step with photos so you see exactly what we found under the old roof.
- Supreme 3-tab failing early on low-slope sections. Owens Corning’s Supreme line is a 3-tab shingle, and 3-tabs have no business on a Miami roof below a 3:12 pitch. In a downpour, water backs up under the tabs and finds the nail holes. The result is a slow leak that rots decking from the inside. When we replace a Supreme roof on a low-slope section, we don’t put 3-tab back. We convert to a properly rated architectural shingle or, if the pitch is genuinely too low, a flat roofing membrane. The code and the climate both demand it.
- VentSure and WeatherMax underlayment failures after partial repairs. The underlayment is the layer under the shingles that does the real waterproofing, and Miami homeowners who had a patch job done in a hurry often see the seam tape on the old underlayment start to peel. We remove all old underlayment on every replacement and install fresh synthetic underlayment in full runs, not patched pieces, so there are no seams in the worst-wear zones.
- Decking rot along the Brickell corridor and coastal zones. Salt air and high humidity eat plywood decking faster than most people realize. We routinely find decking soft spots under Owens Corning roofs within six blocks of the water. When we pull the old shingles, every inch of decking gets inspected, and we test for delamination. If a sheet fails the screwdriver test, it comes out and gets replaced with H-clip-spaced CDX plywood, nailed to current Miami-Dade code. We don’t shingle over rot. That’s how you get a $20,000 failure disguised as a $9,000 replacement.
Styles & brands we work with
Our Owens Corning Roof Replacement Process
We’re an independent Owens Corning service provider. That means we’re not tied to a corporate installer network, and we don’t mark up materials the way authorized dealer programs often do. We install Owens Corning systems because they hold up in Miami when the right line is chosen for the right pitch and exposure, and we also work with GAF and CertainTeed when a different material spec makes more sense for your home.
- 1
Call (850) 318-3769 and schedule the inspection. A live person answers. You’ll get a date and a live trackable arrival time, so you know when Dylan Pace or one of our lead techs will be on your roof.
- 2
Full roof assessment. We walk the roof, check the attic for ventilation, test decking for soft spots, and document everything with photos. You see what we see, whether you choose to replace or not.
- 3
Written scope and line-item price. Before any work starts, you get a written proposal that lists the Owens Corning line we recommend, the underlayment spec, the fastener schedule, the decking allowance, and the exact dollar figure. The number on the page is the number on the invoice, guaranteed by The Relay Visibility Guarantee.
- 4
Tear-off and decking repair. Old shingles and underlayment come off down to the sheathing. Any rotted decking gets replaced and photographed. Drip edge and flashing, which are the metal strips that seal joints around chimneys, vents, and walls, get replaced or re-set to Miami-Dade code.
- 5
New Owens Corning system installed. Fresh synthetic underlayment goes down, then new starter course, shingles, hip and ridge caps, and ventilation. We nail to manufacturer spec and current wind code, which matters more in Miami than in almost any other market in the country.
- 6
Post-install photos and final walkthrough. You get before-and-after photos of the entire job plus a digital invoice sent by text. We walk the property with you, make sure the yard is clean and the roof is watertight, and then the 365-Day Done Right Promise kicks in. If anything we touched fails within a year, we come back and fix it at no charge. That’s a written guarantee on every job.

AfterWhat Owens Corning Roof Replacement Costs in Miami
Miami pricing comes down to roof size, pitch, material line, decking condition, and accessibility. Here’s what we typically see on Owens Corning replacements:
- 1,200 to 1,800 sq ft roof, Duration or Oakridge architectural shingles: $8,400 to $12,900.
- 2,000 to 3,000 sq ft roof, Duration architectural: $11,500 to $18,600.
- Decking replacement (when rot or delamination is present): $2 to $3 per square foot of replaced decking, added to the base scope.
- Flat or low-slope sections requiring membrane conversion: $6 to $9 per square foot of flat area, depending on membrane type and detail work.
- Skylight, chimney, or wall flashing replacement (when flashing is compromised): $85 to $250 per penetration, depending on location and complexity.
What moves the price more than anything is the condition of the decking and the number of penetrations. A clean 1,500 sq ft tear-off with no decking damage stays at the low end. A roof with three skylights, a chimney, and half the decking showing rot pushes higher, and honestly, that’s where the surprises live if your roofer doesn’t inspect before quoting. We inspect before quoting, and our written price reflects what we actually found. Call (850) 318-3769 for a free estimate and an exact number in writing.
Why Miami Homeowners Call Crestview Roofing Co Miami for Owens Corning Work
Owens Corning makes good shingles, but the company that installs them determines how long they last in Miami. We’ve built our reputation on what happens before and after the install, not just during it. Every job gets a written price before any work starts. Every job gets before-and-after photo documentation. Every repair and replacement is covered by the 365-Day Done Right Promise: if a covered repair fails within one year, we correct it at no charge. No negotiation, no fine print, no chasing us on the phone, because a live person answers our line 24/7. And when Owens Corning isn’t the right tool for a particular Miami roof, we install GAF or CertainTeed instead and tell you why. Every promise in writing, because a roof shouldn’t come with fine print.
FAQs
No. As an independent Owens Corning service provider, we install to manufacturer specifications, which is what the warranty requires. We don’t take shortcuts on fastener count, underlayment, or ventilation, because doing so would both shorten the roof’s lifespan and put your materials warranty at risk. What you do lose when a previous installer cut corners is the ability to claim against a warranty that was already violated by whoever did the original work. We’ll tell you if we find evidence of that during the inspection, and we document it in photos.
Most standard single-family replacements are done in one to two working days once materials are on site. Larger homes, steep pitches, multiple roof planes, or significant decking replacement can extend that. Miami’s afternoon storm pattern is a real factor, so we stage tear-off work so no exposed decking sits overnight without a waterproof covering. Call (850) 318-3769 with your square footage and we’ll give you a realistic timeline with your written estimate.
It depends on the age and spread of the failure. Isolated damage, like a handful of shingles lifted on one slope after a storm, is a repair. Widespread granule loss, curling at the edges, or soft decking under the shingles means replacement, and patching over that only moves the leak somewhere else. Our rule is simple: if the repair cost times two exceeds sixty percent of the replacement cost on a roof that’s already past half of its expected life, replacement is the honest recommendation. We’ll show you photos either way, and the written estimate is yours to keep whether you book the work or not.
Yes. Roof replacement in Miami requires permits, and we handle permit applications and inspections as part of the scope. Miami-Dade has some of the strictest wind codes in the country, and the inspection process exists for a reason. We build to code, we document the build, and we don’t pass the cost of a failed inspection on to you.
Not unless we find something hiding under the old shingles that no inspection could have caught, and we’ll tell you that before you commit. That’s the difference between a written price and an allowance guess. We inspect before we quote, we photograph everything, and we spell out exactly what decking, flashing, and ventilation work is included. If we open the roof and find rot we couldn’t have seen from the top, we’ll show you photos, give you a written change order, and nothing proceeds until you approve it. No arguments after the job, no surprise invoice. Call (850) 318-3769 for your free written estimate.
