New color options expand design possibilities for asphalt shingles

Learn how a new color collection and proven technologies  give homeowners and contractors more design flexibility with Timberline HDZ® shingles. 

The Timberline HDZ® shingle continues to anchor the GAF residential roofing portfolio as its best-selling product, reflecting the company’s ongoing emphasis on both visual design and long-term performance. With the introduction of the new Bold Definition color collection, the product line now offers homeowners more ways to enhance curb appeal while maintaining the durability and reliability associated with the Timberline HDZ ® name. 

According to Ashley Alfonso, Senior Residential Product Manager at GAF, the expanded color selection responds to growing interest from both homeowners and contractors seeking greater aesthetic flexibility. “We wanted to give both homeowners and contractors a real choice in aesthetics backed by the Timberline HDZ® name, which has stood the test of time after over a decade in development and over six on the market,” Ashley said. 

While the new colors broaden design possibilities, the product continues to prioritize performance. Timberline HDZ shingles are backed by the WindProven™ Limited Wind Warranty, which provides an industry-first 15-year infinite wind speed protection when the shingles are installed with four qualifying GAF accessories, starter strips, roof deck protection, ridge cap shingles and either a leak barrier or attic ventilation. Together, these components help strengthen the overall roofing system under severe weather conditions. 

Additional protection comes from the StainGuard Plus™ Algae Protection Limited Warranty, which uses time-release technology to guard against discoloration caused by blue-green algae. Ashley noted that the coverage helps preserve a roof’s appearance over time, describing the algae technhology as “important to homeowners, as it helps prevent algae-staining, so your roof will continue to look beautiful over time.” 

The shingles also carry a Lifetime† Limited Warranty against manufacturing defects and meet UL 2218 impact testing standards with a Class 3 impact rating, which can provide added protection in hail- and storm-prone regions. 

At the same time, GAF continues expanding the visual palette available to homeowners. The established High Definition® color collection includes nine widely available shades such as Barkwood, Charcoal, Hickory, Hunter Green, Mission Brown, Pewter Gray, Shakewood, Slate and Weathered Wood, with additional regional options offered in select markets. 

Building on that foundation, the new Bold Definition color collection introduces deeper tones and stronger contrasts designed to enhance roof visibility and architectural character. Available nationwide, the collection includes Chestnut Valley, Cliffside, Midnight Mesa and Sierra Sand. 

“The High Definition® look is what GAF is known for; the look homeowners and contractors know and love,” Ashley said. “We wanted to continue innovating to give homeowners that extra wow factor with the Bold Definition colors, allowing their roof to be the star of the home's curb appeal.” 

The shingles also incorporate LayerLock® Technology and the StrikeZone™ Nailing Area, which expand the fastening zone to support faster installation and improved nailing accuracy. 

Together, the expanded color collections and engineered installation features reflect a continued focus on helping homeowners choose roofing systems that combine visual appeal, installation efficiency and long-term protection.
