Owens Corning Roof Installation in Orlando: What to Know First
Owens Corning roof installation in Orlando typically runs $8,500 to $16,500 for a full tear-off and replacement on a standard single-family home, with most jobs completed in two to four days once materials arrive. We’re an independent Owens Corning service provider, not a manufacturer-authorized dealer, which means we recommend what’s actually right for your house rather than what a corporate program tells us to push. If you’ve got an Owens Corning roof that’s reaching the end of its life, or you’re considering Owens Corning shingles for a new install, this page covers pricing, product lines, failure patterns, and what the process looks like from the first call to the final nail. Call (850) 757-3564 for a written estimate before any work begins. That’s how we do every job.
How Owens Corning Products Fail – and How We Fix Them
After nearly two decades in the trade, Grant Whitlock has seen certain Owens Corning failure patterns show up again and again across Orlando neighborhoods. Here’s what we actually find on local roofs, and what we do about it.
- Duration Series granule loss on sun-facing slopes. The Duration line (including Duration FLEX and Duration STORM) uses thick granules for impact resistance, but Orlando’s south-facing roof planes bake in direct sun for six to eight hours a day. We regularly see granule shedding that leaves the asphalt layer exposed, which accelerates cracking. When granule loss covers more than 30% of a slope, we don’t patch it, we plan a full roof installation of that section. Patching sun-baked shingles just moves the problem down the roof.
- Oakridge series nail-line blow-offs during summer storms. Oakridge is a solid budget-to-mid-range shingle, but its nail line sits higher than some competitor brands. When the original installer nailed above that line (a common occurrence on fast-tracked Orlando new-builds), the shingles let go during the afternoon thunderstorms that roll through Lake Nona and Winter Park between June and September. We inspect the nail placement before quoting any repair. If the original install missed the nail line, a repair won’t hold, and a new roof installation is the honest answer.
- Decking rot under Owens Corning shingle-over jobs. A lot of Orlando homes built in the 1990s and early 2000s have Owens Corning shingles installed directly over the original roof, a common practice at the time. The problem is that a shingle-over hides decking rot until it’s advanced. Florida humidity, combined with hidden leaks, turns OSB decking soft. We’ve pulled up Owens Corning shingles in Dr. Phillips and found decking you could push a screwdriver through. Any roof installation we do includes a full decking inspection, and we tell you before we touch a sheet what replacement decking will cost per panel.
- Plastisol flashing failures at penetrations. Owens Corning’s accessory line includes plastic plumbing boot flashings on many mid-tier installs. Orlando’s UV index chews through plastisol faster than metal, and we see cracked boots around vent pipes after six or seven years. The fix is a metal flashing replacement during the roof installation, not a smear of caulk. We default to metal because it outlasts plastic by a decade or more in this climate.
- Ice and water shield gaps at Orlando valleys. The Owens Corning WeatherLock system is a quality underlayment, but it’s only as good as the install. We commonly find valleys where the original crew cut corners and skipped the peel-and-stick underlayment entirely, trusting the shingles alone. That’s a leak waiting to happen when a tropical storm pushes water sideways. Our roof installations include WeatherLock or an equivalent peel-and-stick membrane in every valley and around every penetration, no exceptions.

Our Owens Corning Roof Installation Process
Every roof installation we run follows the same sequence, and you’ll know what’s happening at each step because we put everything in writing before the first shingle comes off.
- 1
The written estimate. We inspect the roof, check the attic, look at nail placement and decking condition, then hand you a price before any work starts. No vague numbers, no “we’ll see what we find.” Grant is known for straight talk on pricing, and the number on your estimate is the number on your invoice.
- 2
Materials decision. We review which Owens Corning line fits your home, whether that’s Oakridge for a budget-conscious replace, Duration for better wind and impact resistance, or Duration STORM if you want the strongest Owens Corning option. We also keep GAF and CertainTeed options in the conversation so you can compare what you’re actually paying for.
- 3
Tear-off and decking inspection. The old roof comes off, and we walk the decking with you if you want to see it. Any rotted or soft panels get replaced at the per-sheet price we quoted you before we lifted a shingle. No change orders that surprise you.
- 4
Underlayment, flashing, and install. We run peel-and-stick membrane in valleys and around penetrations, replace all flashing with metal where possible, and install the shingles to the manufacturer’s nail line and pattern. This is where the crew’s experience with Orlando’s wind and rain shows.
- 5
Cleanup and inspection. Magnets for nails, a walk of the property for debris, and a final look at every seam and ridge. We don’t leave until the ground around your house looks better than it did when we arrived.
- 6
The 365-Day Done Right Promise. We put the guarantee in writing. If something isn’t right within a year, we make it right. That’s not a slogan, it’s on paper.

Why Orlando Homeowners Call Mercer Roofing Co Orlando for Owens Corning Work
Most roofing companies can nail down shingles. The part that’s harder to find is knowing exactly who’s walking up your driveway. Before our technician arrives, we send you their name and photo. When they get to the door, they’re in a clean, marked uniform and they’ll show you a photo ID badge. Every one of our techs is background-checked and identity-verified under the Threshold Verified standard, part of the Threshold Group family that’s held every location to that bar since 2000. We answer the phone with a live person 24/7, not a call-back form. And since Grant and the crew work with GAF and CertainTeed alongside Owens Corning, you’ll get a recommendation that fits your roof and your budget, not a one-brand pitch.
A roof shouldn’t be a mystery – let’s talk about what’s actually up there.
FAQs
No. Owens Corning warranties apply to the materials, not who installs them, as long as the shingles are installed according to manufacturer specifications. As an independent Owens Corning service provider, we install to the manufacturer’s nail pattern, ventilation requirements, and underlayment specs so your material warranty stays intact. Call (850) 757-3564 and we’ll explain exactly how warranty coverage works for your specific Owens Corning line.
Most full roof installations take two to four days once materials are on site, depending on the home’s footprint, roof complexity, and whether decking replacement is needed. Weather plays a role too, Orlando’s afternoon storms can pause a job for a few hours. We’ll give you a schedule in writing before we start, and we’ll keep it updated if weather changes the plan.
If the shingles are less than 12 to 15 years old and the damage is localized, which usually means a single slope, a few missing shingles, or isolated flashing failures, a repair makes sense and we’ll cover it with a written guarantee including a free second visit if it fails. If the roof is 18-plus years old, has granule loss on multiple faces, or shows nail-line blow-offs, a new roof installation is typically the smarter money. We’ll tell you which is which without pushing you to spend more than you need to.
Not on our end. We give you a written price before work starts, and that price holds. The only variable is decking, and we quote you a per-sheet price before the tear-off so there are no surprises if we find rotted panels. If we find damaged decking, we’ll show it to you before replacing it.
Yes. A roof installation in Orlando requires a permit, and handling that is part of our process, including scheduling the required inspections. We don’t ask you to handle paperwork or make calls to the building department. We’ll tell you at the estimate what the permit fees and schedule look like for your specific property.
