GAF has recently introduced Timberline® UHDZ™ Shingles, a premium upgrade of their best-selling Timberline HDZ® Shingles. These new shingles bring all the benefits that homeowners love about Timberline HDZ® Shingles, but with enhanced features like improved aesthetics and advanced algae-fighting technology. If you’re trying to decide which option is best for your project and budget, here’s a quick comparison of what each product offers.

Boost Curb Appeal

Both Timberline® UHDZ™ and Timberline HDZ® Shingles offer a stylish, wood-shake appearance that enhances a home’s curb appeal and can increase its value. The new UHDZ™ Shingles, however, take it a step further with a unique Dual Shadow Line feature. This feature creates an ultra-dimensional, deeply defined look that’s visible throughout the day, thanks to the “sunset shadow effect.” Additionally, the UHDZ™ Shingles are thicker, which adds to their dimensional appearance.

Comparing Costs

While Timberline HDZ® Shingles are more budget-friendly, offering high quality at an affordable price, Timberline® UHDZ™ Shingles provide extra features that justify their slightly higher cost. Homeowners who understand the difference between the two might find the additional investment in UHDZ™ Shingles worthwhile.

Warranty Benefits

Warranties provide peace of mind, and both Timberline HDZ® and UHDZ™ Shingles come with impressive coverage. When installed with the required combination of four qualifying GAF accessories, both shingles offer a 15-Year WindProven™ Limited Wind Warranty*, which has no maximum wind speed limitation.

Timberline® UHDZ™ Shingles also include a 30-year StainGuard Plus Pro Limited Warranty against blue-green algae discoloration**. This is due to the shingles featuring 10% more GAF Time-Release Algae-Fighting Technology than the HDZ® version. However, Timberline HDZ® Shingles still come with a competitive 25-year StainGuard Plus Limited Warranty against algae discoloration***.

Design Choices

Both shingle lines come in a variety of attractive colors. Timberline HDZ® Shingles are available in options like Charcoal, Birchwood, Hunter Green, and White. Meanwhile, Timberline® UHDZ™ Shingles are offered in Pewter Gray, Charcoal, Barkwood, Slate, Weathered Wood, and Shakewood. Although the UHDZ™ Shingles offer a similar color range, the HDZ® Shingles have a slight edge in terms of more color choices.

Smooth Installation Process

Both Timberline HDZ® and UHDZ™ Shingles are designed for easy and efficient installation. Thanks to GAF’s LayerLock® Technology and the StrikeZone® Nailing Area, crews can quickly and accurately install these shingles, ensuring a seamless process regardless of the product chosen.

Which Shingle Is Right for You?

The final decision on shingle style and color will ultimately be made by the homeowner, but with this comparison in mind, contractors can guide their clients to make the best choice for their roof. Understanding the differences between Timberline HDZ® and Timberline® UHDZ™ Shingles allows you to provide valuable insights to your customers.
