Selling Shingles on Beauty and Performance
Installation confidence for your crew, color options, and warranty benefits for your customers

When it comes to residential roofing, the balance between curb appeal and durability is a concern for most homeowners. GAF Timberline HDZ® shingles represent a legacy of relentless innovation, delivering the peak performance and dependability customers trust. One trusted brand appeals to even more homeowners now by offering two distinct color collections (US Only) to complement any home.
For those who prefer the classic Timberline® look, the High Definition® colors use patented shadow bands to create exceptional depth and dimension. However, for homeowners looking to make a bolder statement, GAF now offers the Bold Definition collection. These shingles are bursting with rich tones and striking contrasts, curated to deliver distinct looks that stay in style. Inspired by current shingle trends, this collection features four new vibrant colors:
- Chestnut Valley
- Cliffside
- Midnight Mesa
- Sierra Sand
Customers can select from these two color collections, in a wide variety of shades, to complement their home and curb appeal. Plus, with more than just aesthetics, Timberline HDZ® shingles offer your customers peace of mind with industry-first technologies and powerful warranties.
