Ultra-heavy-duty shingles with deeper shadow lines.
The Timberline UHDZ® is GAF's most premium standard architectural shingle — heavier, thicker, and engineered for homeowners who want a substantial, dimensional look without stepping up to designer pricing.
What makes UHDZ different.
The UHDZ takes everything that makes the Timberline HDZ® great — LayerLock™, the StrikeZone™ nailing area, WindProven™ eligibility — and adds thicker, ultra-dimensional tabs that throw deeper shadow lines and create a more upscale appearance from the curb.

The shadow lines you notice from the street.
If your home has steep visible slopes, dormers, or front-facing gables, UHDZ's deeper definition makes a real difference. Most homeowners can spot the upgrade from across the yard — and so can buyers if you ever sell.
