At RoofCrafters, with 30 years of experience installing various shingles, we understand the confusion and want to help. We won't provide biased opinions, just facts. Both Landmark Pro and Timberline HDZ shingles offer distinct features and benefits that might suit your home. Our job is to point them out, assisting you in choosing the shingle that best meets your needs.

In this article, we aim to provide you with an in-depth comparison of CertainTeed's Landmark Pro and GAF's Timberline HDZ shingle. You'll learn about the background of Certainteed and GAF and why it matters, the similarities and differences between Landmark Pro and Timberline HDZ shingles (including features, benefits, and drawbacks), and the warranties each brand offers for their shingles/what they cover.

CertainTeed vs. GAF: Background & Size

 

When choosing the right shingle for your roof, understanding the background and size of the manufacturer is crucial. In this section, we'll closely examine CertainTeed and GAF, the two brands behind the Landmark Pro and Timberline HDZ shingles. But before we dive in, acronyms like HDZ need context to be useful, right?

For clarification, the HDZ in the Timberline shingles stands for High Definition, and the Z stands for LayerLock Technology. Glad we got that cleared up! Also, their order doesn't imply ranking—just because CertainTeed is listed first doesn't mean we rank them higher.

CertainTeed boasts over a century of industry presence, making it a well-established brand. They offer a variety of exterior and interior building products, including roofing, siding, fence, decking, railing, trim, insulation, gypsum, and ceilings.
