Identifying the Top Asphalt Shingle for Wind Resistance


When it comes to standing up against strong winds, the GAF Timberline HDZ shingle takes the lead in the asphalt shingle market. It offers an unparalleled wind protection warranty, covering unlimited wind speed for an impressive 15 years. This level of protection sets the Timberline HDZ apart as the industry benchmark.

To qualify for the warranty, GAF requires four nails per shingle. Additionally, four other GAF products must be used together. These extra items are vital parts of a full roof system. They guarantee the greatest strength and safeguard.

Other leading brands guarantee their shingles for wind speeds up to 110 mph. The other brands also offer the option to extend the guarantee to 130 mph by following special installation guidelines. The GAF Timberline HDZ shingle has a better wind resistance warranty. This warranty clearly outshines the warranties of other options. So, it is an ideal choice for homes in windy areas.

Infinite wind speed protection! If you are asking yourself why or how that is possible, we’ll explain in this next section.

The Engineering Behind GAF Timberline HDZ's Enhanced Wind Protection


The GAF Timberline HDZ shingle has exceptional wind resistance. GAF redesigned its popular Timberline HD line to achieve this. The first Timberline HD shingles were sealed together, but GAF found a problem. The main problem? The biggest issue was it only gave the installers a narrow area for accurate nail placement.

GAF developed the LayerLock Technology. The new HDZ shingles are mechanically fastened. So now the upper and lower parts of the shingle can’t separate. This solved the issue of the shingle separating. And by doing so also widens the nail zone. This is a win-win. The shingles will not delaminate and the installers have a wider area for nail placement. 

But wait…there’s more!

Ok, that was supposed to sound like one of those cheesy info commercials. Lol,  anyway back to these HDZ shingles. GAF also created a new sealant that gets added during the manufacturing process. It’s called Dura-Grip technology. It’s a modified bitumen sealant. It helps seal shingle the shingles together. Just below the wider nail zone.

Yep, you guessed it. The bottom of the wider nail zone is also used to hold the shingles together. Once the Dura-Grip sealant heats up, the new HDZ shingles bond together. Let us tell you, we’ve tried to pull them apart and it’s nearly impossible. This is why they won’t blow off.

By re-engineering the Timberline HD shingles into the new HDZ version, GAF enhanced the product's resilience to wind. They focused on improving the design. This ensured a broader and more forgiving area for nail placement. It significantly reduced the risk of shingle separation due to installation errors. GAF Timberline HDZ shingles are the top choice for wind protection. They dominate the market for asphalt shingles. This is because of their thoughtful redesign.
