CertainTeed, a leading North American manufacturer of sustainable building materials, is expanding its CoolStar Ultra commercial roofing portfolio with the introduction of Flintlastic SA Cap CoolStar Ultra, bringing Title 31 compliant, highly reflective cool roof technology to its industry-leading self-adhered low-slope roofing systems. A fire-resistant (FR) version of Flintlastic SA Cap CoolStar Ultra is also available for assemblies requiring high solar reflectivity in combination with a Class A fire rating and/or Class IV impact resistance.
CertainTeed previously launched Flintlastic GTA CoolStar Ultra and Flintlastic GTA-FR CoolStar Ultra, offering contractors and building owners torch-down solutions that meet Los Angeles’ Title 31 Green Building Standards Code (T31). With this latest expansion CertainTeed now extends CoolStar Ultra technology to customers who prefer self-adhered roofing systems, delivering greater installation flexibility while maintaining high solar reflectivity and long-term performance. These products are listed with the Cool Roof Rating Council (CRRC Product ID: 0668-0161 and 0668-0162).
“As demand grows for safer, faster-installed cool roofing solutions, we’re continuing to expand where CoolStar Ultra can be used,” says Liang Gwee, product manager of commercial roofing at CertainTeed. “By bringing CoolStar Ultra technology to our self-adhered systems, we’re delivering a high-reflectivity, Title 31 compliant solution that installs faster, eliminates flames and fumes, and provides the long-term durability and multi-ply protection customers rely on.”
S.A.F.E. Roofing with Flintlastic SA
Flintlastic SA systems are engineered with the S.A.F.E. roofing approach—Speed, Affordability, Fume & Flame Free, and Easy to Learn—helping contractors complete projects more efficiently without sacrificing performance.
Speed. CertainTeed commissioned an independent third-party comparison of labor efficiencies across multiple popular low-slope roofing systems, including multi-layer modified bitumen and single-ply. Results showed that a two- or three-ply Flintlastic SA system installed faster than traditional modified bitumen application methods and single-ply systems. Contractors can view the side-by-side time trial for additional insights.
Affordability. While material costs for multi-ply modified bitumen systems may exceed single-ply, labor efficiencies help offset those differences. When labor savings are factored in, installed costs are comparable, while delivering the superior protection of a multi-ply roof system.
Fume & Flame Free. Flintlastic SA eliminates the need for kettles or torches. Installation requires only a weighted roller to achieve a bond comparable to traditional modified bitumen methods.
Easy to Learn. CertainTeed Credentialed Contractors report faster skill acquisition with Flintlastic SA self-adhered installation compared to other roofing application methods.
Cool roofs help reflect sunlight and reduce heat absorption, mitigating the urban heat island effect, lowering smog formation, and decreasing peak electricity demand. CertainTeed’s expanding CoolStar Ultra portfolio supports building owners and contractors seeking durable, energy-efficient roofing solutions that comply with Title 31 in Southern California and beyond. In addition to Title 31 compliance,
CertainTeed’s existing CoolStar roofing products remain Title 24 compliant statewide across California
