Welcome to Part 2 of our series on GAF asphalt roofing solutions.
In Part 1, we covered the GAF Timberline HDZ shingle line, and in this installment of the series, we’re taking a look at Timberline UHDZ siding.
UHDZ stands for “Ultra High Definition Shingles,” and they’re truly a sight to behold. Coupled with GAF’s UltraMat high-performance fiberglass mat technology, these shingles are a premium product that Madison-area homeowners love.
The UHDZ line can also be upgraded to a GAF FORTIFIED Roof, adding an additional layer of strength to GAF’s already robust, durable asphalt roofing systems.
Before we dive in, here’s a quick visual comparison between Timberline’s HDZ and UHDZ lines …

BENEFITS OF TIMBERLINE UHDZ ROOFING INCLUDE …
- It is a premium laminate shingle, and is a heavier grade than the Timberline HDZ shingle
- GAF’s UltraMat high-performance fiberglass mat technology enhances the shingle at its core and is rated UL 2218 Class 41 for impact-resistance
- UHDZ’s patent-pending dual shadow lines for, “dramatic sunset shadows all day long” giving the roofing a beefier look. This is complimented by six attractive color blends (all shown below).
- This product can be used to comply with certain wind requirements for FORTIFIED Roof
WARRANTIES
GAF is well known for their outstanding warranties on their products. Here’s a quick overview of all the warranties included with the UHDZ line of asphalt shingles:
- StainGuard Plus PRO™ Algae Protection Limited Warranty
- WindProven™ Limited Wind Warranty
- Layerlock™ Technology
- DuraGrip Adhesive
If you’re interested in learning more about these warranties, you can find additional info on our GAF Roofing page, or get in touch with us anytime.
Note: When you have Legacy Exteriors install your new roof, these warranties are strengthened — at no additional cost — because we are GAF Master Elite, GAF President’s Club, and GAF FORTIFIED certified installers.
For example, as a GAF Master Elite contractor, we can offer 30 years of workmanship coverage when we install any qualifying GAF roofing system with Timberline UHDZ shingles, as well as register a Golden Pledge Limited Warranty. The Golden Pledge Warranty is the highest-tier residential roofing warranty GAF offers, delivering 50 years of 100% coverage for material defects, as well as 25 years of coverage against workmanship errors. In order to qualify for this, your roofing must be installed by a GAF Master Elite contractor, using only GAF Lifetime Roofing System components — as well as a mandatory post-installation inspection.
