Call us at (214) 321-9341 for a no-obligation estimate and evaluation. Even if you are unsure, there is no cost for us to take a look at your roof, and in hail-prone North Texas it is smart to have it checked every couple of years.
GAF Timberline HDZ Is North America's Best-Selling Shingle
GAF Timberline HDZ is one of the most popular architectural shingles in North America, combining curb appeal with long-term performance. These laminated shingles are designed to mimic the look of wood shakes while offering the low maintenance of asphalt.
Key advantages homeowners notice:
- Attractive dimensional look that upgrades most three-tab or older architectural roofs.
- Strong fiberglass asphalt construction with a Lifetime Limited Warranty when installed as part of a qualifying system.
- LayerLock and StrikeZone nailing area technology, which improves install accuracy and wind performance.
- Impact-resistant options in certain Timberline lines for better hail performance.
For manufacturer detail, see GAF's official Timberline HDZ page.
We also install other GAF products including Royal Sovereign. Ask about ArmorShield, GAF's UL 2218 Class 4 impact-resistant shingle, which can be a smart upgrade in Dallas-area hail zones.

Timberline Roofs Tailored to North Texas Homes
North Texas weather is hard on roofs. We routinely see hail, high winds, intense summer heat, and occasional winter freezes. A properly installed Timberline roof, combined with the right underlayment, ventilation, and accessories, holds up better to these conditions. On many projects we also:
- Upgrade to impact-resistant shingles where appropriate.
- Improve attic ventilation for better shingle life and energy performance.
- Replace or upgrade flashing and critical details, not just the visible shingles.
