GAF Timberline HDZ® Shingles
Installed in Tulsa, Broken Arrow & NE Oklahoma
GAF's #1-selling architectural shingle. Two color collections (High Definition® and Bold Definition), Class 3 impact resistance, algae protection, and eligibility for GAF's no-maximum-wind-speed warranty.
The Oklahoma verdict
Timberline HDZ is rated UL 2218 Class 3 (it survives a 1.75-inch steel ball dropped from 20 feet). That handles most Tulsa-metro storms well. If your neighborhood has taken hail two or more times in the last five years, we usually suggest stepping up to a Class 4 version of the same look.
Compare it with our Class 4 cost-vs-savings math and the hail-damage checklist.

Frequently asked questions
Is Timberline HDZ impact resistant?
Timberline HDZ carries a UL 2218 Class 3 rating. That is one step below the Class 4 rating most insurers look for when offering a hail credit. If a discount matters to you, ask us about the Class 4 version of the same look.
What is the wind warranty on Timberline HDZ?
15-year WindProven™ Limited Wind Warranty with no maximum wind-speed limit (requires LayerLock® shingles plus GAF starter strips, roof-deck protection, ridge cap and leak barrier or attic ventilation). Wind warranties from every manufacturer depend on using the brand's starter strips and hip & ridge, which is how Maxx Roofing installs every roof.
How much does a Timberline HDZ roof cost in Tulsa?
Price depends on roof size, pitch, layers to remove, decking condition and the accessories (underlayment, ice & water shield, ventilation) the system needs. We give a written, line-item estimate after a free on-roof inspection, and 9 out of 10 roofs we replace are paid through an insurance claim.
