Impact
Class 3
GAF lists UL 2218 Class 3 for qualifying labeled packages. Laboratory classification does not mean hail damage is covered.
Surface
Time-release algae protection
Qualifying shingles carry StainGuard Plus algae protection; confirm the packaging and written coverage for the selected color.
Color collection
See the roof, not just the swatch.
Screen color is a starting point. Confirm current availability and review a physical sample outdoors against the home before ordering.

WindProven eligibility depends on using the required combination of GAF accessories and following installation requirements. Material, wind, algae, and contractor workmanship coverage are separate; compare the actual documents supplied with your proposal.
Confirm current regional supply and the exact product designation before ordering. Manufacturer photography shows product appearance and is not a Texas Professional Roofing project claim.

Three questions worth answering.
Is Timberline HDZ right for every roof?
No single shingle fits every property. Roof geometry, deck condition, ventilation, exposure, visual goals, budget, availability, and the complete installed assembly all shape the decision.
How should I compare the colors?
Use these images to narrow the field, then review a current physical sample outdoors and compare full-roof photographs on homes with similar exterior materials.
What belongs in the written proposal?
The exact shingle and color, accessory components, underlayment, starter and ridge materials, ventilation, flashing, deck allowances, fastening details, disposal, schedule, and applicable product and workmanship documents.
