CertainTeed Roof Installation in Orlando: What to Know First
CertainTeed roof installation in Orlando typically runs $9,800 to $18,500 for a full tear-off and replacement on an average single-family home, with most jobs completed in two to four days once materials are on site. We’re an independent CertainTeed service provider, which means we install the shingle you choose and stand behind the labor ourselves, with a written price before any work starts. This page is for Orlando homeowners who already know CertainTeed’s reputation and want straight answers about cost, timing, and what actually happens on install day.

Call (850) 757-3564 and you’ll get a live person, not a voicemail. We’ll talk through your roof, your neighborhood, and what a CertainTeed install looks like at your address.
How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes a solid shingle. But every product line has patterns we see across Orlando roof installations, and knowing those patterns before the first shingle comes off changes how we quote the job.
- Landmark series granule loss after year 12. The Landmark architectural shingle is the most common CertainTeed line we tear off in Orlando. By year 12 or so, Central Florida’s UV load starts wearing the granule coating down, especially on south-facing slopes in neighborhoods like Conway and Belle Isle. You’ll see granules in the gutters and a patchy, lighter color on the roof. The fix during installation is a full deck inspection and new underlayment, because once the shingles are gone we often find the real problem is the old felt underneath, not just the shingle.
- Presidential Shake weight stress on older decking. CertainTeed’s Presidential Shake is a heavy, luxury shingle. On Orlando homes built before the 2002 Florida Building Code changes, the decking wasn’t always rated for that weight. We’ve opened roofs in Winter Park and found plywood that flexed under the load. Before installing Presidential Shake, we check decking thickness and rafter spacing and flag any reinforcement the job actually needs. That conversation happens in writing before we order materials.
- Northgate and XT 25 sealant strip breakdown. The older 3-tab lines like XT 25 and Northgate use a thin thermal sealant strip that loses adhesion after enough Florida heat cycles. When that happens, shingles lift in wind before they’re technically “worn out.” On a re-roof, we don’t reuse or patch over these – we tear off and install to current wind code, which matters in Orlando where summer squalls can hit 60 mph with no warning.
- Flashing failures around Orlando’s stucco chimneys. CertainTeed shingles rarely fail at the field; they fail where the roof meets something else. Stucco chimneys in Orlando hold water, and the step flashing and counterflashing from original installations is often corroded or installed with the wrong lap. During installation we replace flashing with new metal sized to the actual gap, not whatever was there before. It’s the difference between a roof that lasts 20 years and a ceiling stain after one wet season.
- Ventilation mismatches in 1980s and 1990s Orlando builds. A lot of CertainTeed failures we see aren’t the shingle’s fault at all. Homes in areas like Azalea Park and Pine Hills built during those decades often have ridge vents that were installed for looks, with intake vents that never got cut. The attic cooks, the shingles bake from below, and the manufacturer warranty gets denied because the ventilation wasn’t to spec. We correct the intake/exhaust ratio during every CertainTeed install, and we document it with photos.

Our CertainTeed Roof Installation Process
Here’s how a CertainTeed roof installation goes when you call Mercer Roofing Co Orlando.
- 1
Call and talk to a person. You call (850) 757-3564, tell us what you’re dealing with, and we schedule a roof inspection. You’ll know exactly who’s coming before they arrive, name and photo, and they’ll be in a marked uniform with a photo ID at your door.
- 2
Inspection and written scope. Your technician checks decking, flashing, ventilation, and drainage specific to CertainTeed installation requirements. We look at what’s under the shingles, not just what’s on top.
- 3
Written price before any work starts. You get a line-item quote covering tear-off, decking repairs (if any), underlayment, flashing, shingles, and disposal. No number changes mid-job unless we find something structural we couldn’t see, and even then we stop and get your approval in writing first.
- 4
Parts decision: OEM vs. quality aftermarket. For CertainTeed, we install CertainTeed shingles. For the components CertainTeed doesn’t manufacture, like underlayment and flashing, we use code-compliant materials matched to the shingle warranty. We’ll explain the trade-offs in plain English before you decide anything.
- 5
Installation and cleanup. Tear-off, deck repair, underlayment, shingles, flashing, ridge vent or cap, site cleanup with a magnet sweep for nails. We do a final walk-around with you and answer any question.
- 6
Written guarantee on the work. Every installation is covered by our 365-Day Done Right Promise. If it’s not done right within a year, we make it right. That’s in writing, not a handshake.

AfterWhat CertainTeed Roof Installation Costs in Orlando
Here are real numbers for Orlando, not national averages that don’t account for our wind codes, humidity, and labor market.
- Landmark architectural shingle, full tear-off: $9,800 to $14,200 for a typical 1,800 sq ft single-story home.
- Landmark Pro / upgraded architectural: $11,500 to $16,000 same footprint, depending on steepness and decking condition.
- Presidential Shake or luxury lines: $16,000 to $24,000 and up. The decking reinforcement conversation usually happens here, which adds to the number.
- Roof-over (shingles installed over one existing layer, where code allows): $6,500 to $9,000. We rarely recommend this in Orlando because the existing deck and underlayment likely weren’t built for a second roof, and you lose the chance to fix what’s underneath.
What moves the price: roof pitch, number of stories, decking repairs, chimney and skylight count, and whether we need a permit expedite. What doesn’t move the price: any change order we didn’t put in writing and get you to sign off on first. Call (850) 757-3564 and we’ll get you a real number.
Why Orlando Homeowners Call Mercer Roofing Co Orlando for CertainTeed Work
Most roofers in Orlando can install a CertainTeed shingle. What they don’t all do is tell you who’s showing up, what it’ll cost, and what happens if the work isn’t right. We were founded in 2000 and we’re part of the Threshold Group family of home-service companies. That means every technician who walks your property is background-checked, identity-verified, and badged under the Threshold Verified standard. Their name and photo come to you before they arrive, and they’ll present ID at the door before stepping one foot on the property.
We install CertainTeed, GAF, and Owens Corning. If your home already has a CertainTeed roof and you want to stay with the brand, we’ll do exactly that. Grant Whitlock, our owner, learned the trade at Los Angeles Trade-Technical College and has put in nearly two decades of hands-on work. He’s the one who made the rule that every price goes in writing before a nail gun comes out. A roof shouldn’t be a mystery, let’s talk about what’s actually up there.
FAQs
No, provided the installation meets CertainTeed’s published installation specs for Florida wind zone and the system is registered properly after completion. We follow those specs and photograph the process, so if a warranty claim ever comes up, you have documentation, not a he-said-she-said. Call (850) 757-3564 to talk through your specific warranty situation.
Most single-family CertainTeed tear-offs and installations in Orlando take two to four days once materials are delivered. Larger homes, steep pitches, or significant decking replacement can push that to five or six days. We’ll give you a written schedule with your quote.
If the roof is under 10 years old and the damage is localized, like wind-lifted shingles from a summer storm, repair usually makes sense. If you’re past year 12 with widespread granule loss, lifting shingles, or water stains in the attic, replacement is usually the better money. We’ll tell you which one we’d choose if it were our house, and we’ll put the reasons in writing.
We install genuine CertainTeed shingles on CertainTeed jobs. For components CertainTeed doesn’t make, like underlayment and flashing, we select materials that meet the same code and warranty requirements. You’ll see every line item on your written quote before work begins.
Only if we discover something structural that couldn’t be seen during inspection, like rotted decking under an old leak. In that case, the work stops, we show you photos, explain what’s needed, and get your written approval before continuing. We don’t surprise you at the end with an adjusted invoice.
Call (850) 757-3564 to schedule your free CertainTeed roof installation estimate in Orlando. You’ll talk to a live person, get a written price, and know exactly who’s coming to your door before they arrive.
