GAF Timberline HDZ Mission Brown Algae Resistant Laminated High Definition Shingles (33.33 sq. ft. per Bundle)

Mission Brown reads deeper than mid-tone neutrals, which helps traditional brick and stone elevations feel grounded without jumping to near-black charcoal caps.

Within Timberline HDZ, the product story is still the laminated architectural platform documented on the HDZ specification sheet, including line-level UL Class A fire classification and UL 2218 Class 3 impact resistance language.

Bundle math for HDZ is commonly quoted around 33.33 square feet per bundle with three bundles per square; use that as a planning anchor, then reconcile to bundle text and site measurements before purchasing.

Algae-resistant labeling matters for merchandising and homeowner confidence; StainGuard Plus-related warranty content applies to eligible packages as described in GAF warranty literature, not inferred from color names alone.

Installation discipline is where contractors earn margin: straight lines, consistent exposures, and careful handling around hips and ridges reduce rework and callback risk.

LayerLock and StrikeZone are line features; they support training and QC narratives, but they do not replace correct flashing sequence or compatible underlayment selection.

For coastal or high-wind jurisdictions, escalate beyond marketing copy to the manufacturer’s wind-related installation instructions and any locally required product approval listings applicable to the project.
