If you’re replacing a roof in Volusia County, one of the first questions you’ll ask is: which shingle brand is best? For most Central Florida homeowners, the real decision comes down to two names that dominate the asphalt shingle market — CertainTeed and GAF. Both make excellent products. Both are sold across Florida. So how do you choose?
At Affordable Roofing & Construction, we’ve installed roofs across Daytona Beach, Port Orange, New Smyrna Beach, Ormond Beach, DeLand and Deltona for over 20 years. This guide breaks down how these two brands compare on the things that actually matter for a Florida roof — wind resistance, heat, warranty coverage and cost — so you can make a confident decision.
First: The Shingle Line Matters More Than the Brand
Here’s the thing most homeowners don’t realize. The bigger difference isn’t CertainTeed versus GAF — it’s which product tier you buy within each brand. Both companies sell a “builder-grade” 3-tab shingle and a premium architectural (dimensional) shingle. In Florida, you almost always want the architectural line.
- CertainTeed Landmark — the workhorse architectural shingle. Their Landmark PRO and Landmark are extremely popular across Central Florida.
- GAF Timberline HDZ — GAF’s flagship architectural shingle and the best-selling shingle in North America.
These two lines are what most Volusia County homeowners are actually comparing, so that’s what we’ll focus on.
Wind Resistance — The #1 Factor in Florida
Living on the Central Florida coast means your roof has to survive hurricane-force winds. Both brands rate their premium architectural shingles for wind speeds up to 130 mph when installed correctly, which meets and exceeds Florida’s high-velocity requirements.
The key phrase there is installed correctly. A 130-mph shingle is only rated that high when it’s nailed properly, sealed, and paired with the right underlayment and starter strip. This is exactly why the brand on the wrapper matters less than the crew on the roof. GAF’s Timberline HDZ has a wider “LayerLock” nailing zone that makes correct nailing easier, while CertainTeed’s Landmark relies on a well-trained crew hitting the nail line. In both cases, proper installation is what earns the wind rating — and what an insurance adjuster looks for.
Heat & UV — Surviving the Florida Sun
Florida’s brutal summer sun is just as hard on a roof as any storm. Constant UV exposure and 95°+ heat break down asphalt over time. Both brands offer strong performance here:
- Algae resistance — Those black streaks you see on Florida roofs are algae. CertainTeed’s StreakFighter and GAF’s StainGuard Plus both fight this with copper-infused granules. Essential in our humid climate.
- Cool-roof / reflective options — Both brands offer lighter, reflective shingle colors that can lower attic temperatures and cut cooling costs. Pair this with good roof ventilation for the biggest savings.
Warranty Coverage
Both brands offer a lifetime limited warranty on their premium architectural shingles for owner-occupied homes. But there’s a catch homeowners rarely understand: a manufacturer warranty is only as good as the contractor’s certification.
Standard shingle warranties primarily cover manufacturing defects — not workmanship. To get the strongest, longest-lasting coverage, the shingles have to be installed by a manufacturer-credentialed contractor using a full matched roofing system (underlayment, starter, hip & ridge, and ventilation all from the same brand).
Where Affordable Roofing Stands: CertainTeed ShingleMaster
This is where we can offer Volusia County homeowners something most local roofers can’t. Affordable Roofing & Construction is a CertainTeed ShingleMaster™-credentialed contractor — and owner Vladimir Vladimirov holds dual CertainTeed Master Craftsman certifications (Shingle Quality Specialist and Roofing Contractor).
What that means for you:
- We’re trained and certified in CertainTeed’s full installation system — not just laying shingles.
- Our ShingleMaster credential lets us register your roof for extended, manufacturer-backed SureStart™ PLUS coverage that goes beyond a standard shingle warranty.
- You get a documented, code-compliant install that holds up to Florida wind ratings and insurance scrutiny.
To be clear: we install both CertainTeed and other quality shingle systems depending on what’s right for your home and budget. But if you want the strongest available warranty combined with a certified installation, our CertainTeed credentials are a real advantage.

Cost: Are They Priced Differently?
For comparable architectural lines, CertainTeed and GAF are priced very close to each other — the difference per square is usually small compared to the overall cost of a roof. In Volusia County, the price of your roof is driven far more by:
- The size and pitch (steepness) of your roof
- How many layers have to be torn off
- The condition of the wood decking underneath (rotted plywood must be replaced)
- The underlayment and accessories used

CertainTeed vs. GAF: Quick Comparison
- Wind rating (premium line): Both up to 130 mph, installed to spec — a tie for Florida.
- Algae protection: CertainTeed StreakFighter vs. GAF StainGuard Plus — both excellent.
- Ease of correct nailing: Slight edge to GAF Timberline HDZ (wide nail zone).
- Warranty upside with a certified installer: Edge to CertainTeed when installed by a ShingleMaster contractor like us.
- Cost: Roughly comparable for equivalent tiers.
The Bottom Line for Volusia County Homeowners
You genuinely can’t go wrong with either CertainTeed or GAF — both are top-tier brands that perform well in Florida. The single most important decision isn’t the brand; it’s who installs it. A premium shingle nailed wrong will fail in the first big storm, while a properly installed system earns its full wind rating and warranty.
As a CertainTeed ShingleMaster-credentialed, licensed and insured local contractor with 20+ years in Volusia County, Affordable Roofing & Construction gives you the best of both worlds: a great shingle and an installation that stands behind it. Every roof we install includes wind mitigation documentation (which can lower your homeowners insurance) and our 5-year workmanship warranty.
