This guide compares six major shingle brands sold in Florida. All six make an architectural shingle with a lifetime limited warranty against manufacturing defects, and all six make an impact-resistant version.

What each brand is known for
GAF Timberline HDZ
GAF’s flagship architectural shingle. Its WindProven warranty has no wind speed cap and no named-storm exclusion, but only when the roof uses the required GAF accessories. GAF lists Timberline HDZ as State of Florida approved and Miami-Dade product control approved. The standard HDZ is rated UL 2218 Class 3 for impact; ArmorShield II is Class 4.
Owens Corning Duration
Known for the SureNail strip, a wide nailing zone that makes correct nailing easier. Duration carries a 130 mph wind warranty with a 4-nail install. Duration, Duration STORM and Duration FLEX are all covered by a current Miami-Dade Notice of Acceptance (NOA 26-0331.12). STORM and FLEX are the Class 4 versions.
CertainTeed Landmark
Landmark’s base wind warranty is 110 mph, and it rises to 160 mph when CertainTeed starter and hip and ridge are used. It includes a 25-year algae warranty and 10 years of SureStart coverage. ClimateFlex is the Class 4 version with the same warranty terms.
Atlas Pinnacle Pristine and StormMaster
Atlas builds Scotchgard Protector algae resistance into its shingles and uses a larger HP42 shingle size. StormMaster Shake is Class 4 with a 150 mph wind warranty and a Florida product approval (FL 16305). Read our Atlas shingles guide.
TAMKO Heritage and Titan XT
Heritage carries up to a 130 mph wind warranty with TAMKO’s high-wind application. Titan XT raises that to 160 mph with TAMKO starter and hip and ridge, and TAMKO lists Florida Building Code approvals for it. StormFighter FLEX is TAMKO’s Class 4 shingle.
IKO Dynasty and Nordic
Dynasty and Nordic both carry 130 mph wind warranties and use IKO’s ArmourZone nailing strip. IKO lists Miami-Dade product approval and Florida Building Code HVHZ approval for both. Nordic is the Class 4 version.
Is an impact-resistant shingle worth it in Florida?
Class 4 shingles are built for hail, which is less of a threat in Florida than wind. They still help against wind-blown debris, and some Florida insurers offer a credit for them. Get the discount in writing from your insurer before you pay extra.
