GAF Timberline UHDZ vs. HDZ

The Timberline® UHDZ™ Shingles by GAF are a premium upgrade over the Timberline HDZ® Shingles, offering enhanced curb appeal with their ultra-dimensional look and 10% Time-Release Algae-Fighting Technology. While pricier, they provide thicker construction and longer warranty coverage against algae discoloration. Both shingles are easy to install and offer stylish options, but the choice ultimately depends on the homeowner's preferences and budget.
