CertainTeed Flintlastic

SBS Modified Bitumen Roofing from a Trusted American Manufacturer

CertainTeed is one of the most respected names in American roofing, with over 100 years of manufacturing experience. Their Flintlastic line of SBS modified bitumen roofing products brings that heritage to the flat roof market, offering a range of system configurations designed for commercial and residential low-slope applications. Coastal Roofing and Waterproofing Inc. is an authorized installer of CertainTeed Flintlastic systems, serving Broward, Palm Beach, and Miami-Dade Counties with Florida roofing license CCC1330718.

Flintlastic systems carry Florida Product Approval FL2533-R34 and are available in HVHZ-rated assemblies, making them suitable for the most demanding Florida building code requirements.

Flintlastic Product Line

The Flintlastic family includes several distinct products, each engineered for specific installation methods and performance requirements:

Flintlastic SA (Self-Adhered) — This is the flagship product for many Florida installations. The SA system uses CertainTeed's self-adhering technology, which eliminates the need for open-flame torches or hot asphalt. The membrane has a pre-applied adhesive backing that is activated by peeling a release film and pressing the sheet into place. This makes installation safer, faster, and cleaner, with no fumes and no fire risk. The SA system is ideal for residential flat roofs and commercial projects where safety and speed are priorities.
Flintlastic GTA (Torch-Applied) — The GTA product is designed for torch-applied installation, where the bottom surface is heated with a propane torch to create a molten adhesive layer that bonds directly to the substrate or base sheet. Torch-applied systems create an exceptionally strong bond and are often used in commercial applications where maximum adhesion is required. However, torch application involves open flames and requires experienced installers — our team is fully trained in safe torch-applied methods.
Flintlastic FR (Fire-Rated) — The FR version is manufactured with fire-resistant additives that provide a Class A fire rating when installed as part of a complete assembly. This is important for buildings with specific fire code requirements, such as multi-family residential, commercial buildings with occupancy considerations, or properties near property lines where fire spread is a concern. The FR system maintains all the waterproofing and durability properties of standard Flintlastic while adding enhanced fire performance.

Self-Adhered Advantage — No Open Flame

The Flintlastic SA system's self-adhering technology is a significant advantage for Florida roofing. Traditional modified bitumen installation often involves torches or hot asphalt kettles, both of which carry fire risks — particularly on wood-frame buildings common in South Florida. The SA system eliminates these hazards entirely. Installation is also faster and produces no odors or fumes, making it ideal for occupied buildings, schools, healthcare facilities, and residential properties where disruption must be minimized.

Florida Product Approval FL2533-R34

CertainTeed Flintlastic systems carry Florida Product Approval FL2533-R34, which covers specific assemblies for Florida Building Code compliance. This approval documents that the system has been tested and approved for use in Florida, including wind uplift resistance ratings. For HVHZ applications in Broward and Miami-Dade Counties, we use specific Flintlastic assemblies that carry the additional Miami-Dade NOA certification required for those jurisdictions. We verify the correct approval numbers for your specific project before installation.

CertainTeed Flintlastic carries Florida Product Approval FL2533-R34, including HVHZ-rated systems for Broward and Miami-Dade counties.

HVHZ Rated Systems

Flintlastic systems are available in HVHZ-rated assemblies that meet the wind uplift requirements of Broward and Miami-Dade Counties. These assemblies typically use a mechanically attached base sheet — such as CertainTeed DiamondBase — followed by intermediate plies and a cap sheet, creating a multi-ply system with redundant waterproofing and enhanced wind resistance. The HVHZ-rated assemblies are engineered to resist the extreme wind uplift forces that the Florida Building Code requires for buildings within the High Velocity Hurricane Zone.

Cap Sheet Granule Colors

The granule-surfaced cap sheet is the visible top layer of the Flintlastic system, and it is available in several colors to complement your building's aesthetic. Standard color options include:

Slate Gray — A versatile dark gray that complements most architectural styles and hides dirt well.
Russet Brown — A warm brown tone that pairs nicely with stucco and earth-toned exteriors common in South Florida.
Mineral Gray — A lighter gray with subtle variation, offering a clean, contemporary appearance.

Lifespan and Warranty Options

A properly installed CertainTeed Flintlastic modified bitumen roof in Florida typically lasts 20 to 25 years. The SBS-modified asphalt provides excellent flexibility and weathering performance, while the granule-surfaced cap sheet protects the membrane from UV degradation. CertainTeed offers manufacturer warranty options that range from 10-year to 20-year system coverage, depending on the assembly configuration and installation method. As an authorized installer, we can help you select the warranty coverage that best fits your needs and ensure all installation requirements are met for full warranty validity.

Frequently Asked Questions

What is the difference between Flintlastic SA and GTA?

Flintlastic SA is a self-adhered membrane with a pre-applied adhesive backing — no torches or hot asphalt needed. It is peeled and stuck to the substrate, making it safer and faster to install. Flintlastic GTA is a torch-applied membrane that requires heating the bottom surface with a propane torch to create the adhesive bond. GTA creates an extremely strong bond and is often used in commercial applications. SA is preferred for residential and occupied buildings due to its safety advantages. Both products use the same SBS-modified bitumen chemistry.

Is Flintlastic approved for HVHZ in Florida?

Yes. CertainTeed Flintlastic systems carry Florida Product Approval FL2533-R34 and are available in HVHZ-rated assemblies with Miami-Dade NOA certification. The HVHZ assemblies typically use a mechanically attached base sheet (such as CertainTeed DiamondBase) with multiple plies and enhanced fastening patterns to meet the wind uplift requirements of Broward and Miami-Dade Counties. We verify the correct approval and assembly for your specific jurisdiction.

What colors are available for the Flintlastic cap sheet?

The granule-surfaced cap sheet is available in several colors, including Slate Gray (versatile dark gray), Russet Brown (warm brown that complements stucco), and Mineral Gray (lighter contemporary gray). These ceramic granules protect the membrane from UV degradation while providing a finished aesthetic. The color choice is primarily cosmetic — all colors provide the same UV protection and weathering performance.
