CertainTeed Roofing Company in Jacksonville: What to Know First
We repair, replace, and inspect CertainTeed roofs across Jacksonville, and we’re an independent CertainTeed service provider, not a manufacturer-authorized dealer. Most repairs on CertainTeed shingle and flat systems run between $350 and $1,200, and full replacements typically land between $8,500 and $16,000 depending on the line and roof size. You’ll get a written price before any work starts. Every time.
This page is for Jacksonville homeowners who already have a CertainTeed roof and need straight answers on repair costs, failure patterns, and whether a patch job is worth it or a replacement makes more sense. If that’s you, call (904) 719-6346 and a live person picks up. No voicemail, no callback queue.
Key Takeaways:
- We work on all major CertainTeed lines: Landmark, XT 25, Highland Slate, Presidential Shake, and Flintlastic flat systems.
- Every job gets a written price before work begins. The number on paper is the number you pay.
- All work is backed by the 365-Day Done Right Promise: a written one-year guarantee with a free return visit if anything fails.
- Background-checked, uniformed technicians on every job. You’ll know exactly who’s on your roof.
How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes a solid product, but every roof system has weak points, and Jacksonville’s climate finds them faster than most. Here’s what we actually see on CertainTeed roofs in this city, and what we do about it.
- Landmark shingle granule loss on south-facing slopes. Jacksonville’s summer sun beats down hard on south-facing roof planes, and we regularly see Landmark shingles losing granules faster on those exposures than on north slopes. Granule loss exposes the asphalt mat to UV, which accelerates cracking. We inspect for bare patches, document them with photos, and if the decking is still sound, we can often replace the affected slopes rather than the whole roof.
- XT 25 sealant strip failure at eaves. The XT 25 line, which CertainTeed marketed heavily to Florida builders in the early 2000s, has a known issue with the thermal sealant strip letting go near the eaves after years of heat cycling. Wind gets under the tabs, and you end up with shingles flapping or tearing off entirely during a summer thunderstorm. The fix is resealing with a quality aftermarket adhesive or replacing the affected tabs, depending on how far the lifting has spread.
- Highland Slate ridge cap separation. Highland Slate is a heavier architectural shingle, and we’ve found that the pre-formed ridge caps CertainTeed supplies with this line can separate at the nail line when the decking expands and contracts through humid summers and dry winters. We replace failed ridge caps with properly nailed and sealed units, and we check the underlayment at the ridge before re-capping.
- Flintlastic seam splits on flat roofs. CertainTeed’s Flintlastic self-adhered modified bitumen is common on Jacksonville flat-roof additions and porches. The seams are the weak point. We see splits at lap joints where the membrane was installed over dirty or damp decking, or where a cheap primer was skipped. We cut out failed seams, re-prime the surface, and torch or cold-apply new membrane with proper overlap.
- Presidential Shake brittle tabs after impact. Presidential Shake is a thick, expensive shingle, but Jacksonville hailstorms and wind-driven debris crack those tabs just like anything else. The difference is cost: a Presidential Shake replacement runs higher per square than a standard Landmark job. We’ll give you a per-square price before we start so you know the math on replacing ten shingles versus three tabs.

Our CertainTeed Roofing Company Process
Here’s how a CertainTeed job goes from first call to final walkthrough, and why the process matters as much as the parts.
- 1
Call and schedule. A live person answers at (904) 719-6346. We book a visit window that works for you, and the technician shows up inside that window in uniform.
- 2
Inspection and diagnosis. We walk the roof, document what we find, and explain it in plain English. Flashing is the metal that seals transitions like chimneys and vents. Decking is the wood underneath your shingles. Underlayment is the waterproof layer between decking and shingles. Drip edge is the metal strip at the roof’s edge that keeps water from wicking back under the shingles. You’ll hear these words and know what they mean before we quote you anything.
- 3
Parts decision. For CertainTeed jobs, we check current manufacturing availability. Some older lines, like XT 25, are discontinued, so we source either remaining stock, a compatible CertainTeed replacement line, or a quality aftermarket equivalent. We’ll tell you which we’re using and why, and we won’t install a mismatch that voids the remaining manufacturer warranty.
- 4
Written price. The full scope and cost goes on paper before any work starts. No change orders at the door. No surprises after the tear-off.
- 5
Repair or replacement. The crew does the work, cleans the job site, and runs a water test on repairs where practical. Every nail gets checked. Every seam gets sealed.
- 6
Done Right Promise. You leave with the guarantee in writing: one full year, and if anything fails, we come back at no charge. If it’s not right, we’re not done.
What CertainTeed Roofing Company Costs in Jacksonville
Here are honest price ranges for the CertainTeed work we do most often in Jacksonville. These are ballpark figures; your actual quote depends on roof size, accessibility, and condition. You’ll get an exact number in writing before any work starts.
- Shingle repair (Landmark, XT 25): $350 to $700 for typical damage like loose tabs, small leaks, or granule loss on a limited area.
- Flashing replacement: $250 to $600 per penetration (chimney, vent pipe, skylight), depending on what’s rusted or pulled loose.
- Ridge cap replacement: $500 to $1,200 for a typical Jacksonville single-story home.
- Flintlastic flat roof seam repair: $450 to $1,100 depending on the length of the split and whether decking needs spot replacement.
- Full Landmark shingle replacement: $8,500 to $14,000 for an average 2,000-square-foot roof with tear-off.
- Full Presidential Shake replacement: $12,000 to $18,000 for the same footprint; the shingle is heavier and costs more per square.
What moves the price: the number of layers being torn off, whether decking is rotted, roof pitch and walkability, and whether you’re staying in Landmark or stepping up to a heavier architectural line. Call (904) 719-6346 for a free estimate. The number you get on paper is the number you pay.

AfterWhy Jacksonville Homeowners Call Brennan Roofing Co Jacksonville for CertainTeed Work
We’re not the only roofing company in Jacksonville, but we operate under a standard most don’t. It’s called The Garrison Standard, and it’s the same on every job: written price before any work starts, background-checked uniformed technicians who show up inside the promised window, and a full-year written guarantee on every repair and installation. That’s the 365-Day Done Right Promise, and it’s in writing, for one full year, with a free return visit if anything fails.
Travis Oakley runs the Jacksonville operation, and he grew up around construction before spending the better part of two decades working roofs up and down the Florida coast. He’s run flat membrane jobs on commercial strips near Regency Square and full tear-offs in Mandarin, and he’ll tell you what needs replacing and what doesn’t, with a dollar range attached, before he touches a nail. We also install GAF and Owens Corning lines, so if a CertainTeed product is discontinued or not the right fit for your home’s situation, we’ll tell you honestly and show you real alternatives.
Roofers who no-show, shift their price at the door, or leave nails in your flower bed give this trade a bad name. We don’t work that way, and we haven’t since the Garrison Partners family started in 2000. No urgency tactics. No low-ball bids that balloon later. Just a written number, a disciplined crew, and a guarantee we stand behind.
FAQs
In most cases, no. CertainTeed’s shingle warranties cover manufacturing defects, not installation or repair work. Using an independent contractor like us does not automatically void a CertainTeed warranty, as long as repairs are done correctly and don’t cause further damage. We’ll tell you honestly if a repair could affect your remaining coverage, and we’ll document our work so you have a record.
Sometimes, and sometimes not. If the line is still in production, like Landmark in common colors like Moire Black or Heather Blend, we can often match it closely enough that you won’t notice from the ground. If the line is discontinued, like XT 25, or the roof has years of sun fading, a perfect match isn’t realistic. We’ll tell you that before we start, and we’ll show you the closest available option. Call (904) 719-6346 and we’ll take a look.
Common CertainTeed lines and accessories are stocked by Jacksonville suppliers and usually available the same day or next morning. Discontinued lines like XT 25 may take longer, or we’ll recommend a compatible replacement. We’ll give you a realistic time frame when we quote the job, not after you’ve already signed.
It depends on age, decking condition, and the extent of the damage. A CertainTeed Landmark roof under 15 years old with localized granule loss or a few loose tabs is usually a repair. A roof over 20 years old with curling shingles, rotted decking, and leaks in multiple rooms is usually a replacement. We’ll walk the roof, document what we find, and tell you what we’d do if it were our house, with a written price either way.
Every repair and installation we do is guaranteed in writing for one full year. If the work fails within that year, for any reason related to our installation or materials we supplied, we come back and fix it at no charge. It’s not a verbal promise. It’s on paper, and it’s called the 365-Day Done Right Promise for a reason.
