Which Asphalt Shingle Has the Best Wind Protection?


With an unlimited maximum wind speed for a period of 15 years. The GAF Timberline HDZ shingle is the industry’s leading asphalt shingle in wind protection. GAF does require that the shingle have 4 nails and you must use 4 of their other qualifying products. You’ll need those products to do a complete roof system anyway. For reference, the closest brands have shingles that are guaranteed for wind speeds of 110 mph.  And they also offer 130 mph with special installation instructions.

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

Why Does GAF Timberline HDZ Shingle Have the Best Wind Protection?


It’s actually quite simple. GAF decided to re-engineer its most popular shingle line, the Timberline HD shingle. The old Timberline HD(high definition) was laminated together using a sealant. GAF found that this created problems. The biggest issue was it only gave the installers a narrow area for nail placement. The nail placement was critical as it penetrated both sections of the shingle helping keep it from coming apart. So if the installers didn’t have perfect nail placement the shingle could separate.

GAF developed the LayerLock Technology. The new HDZ shingles are mechanically fastened. So now the upper and lower part of the shingle can’t separate. This solved the issue of the shingle separating. And by doing so also widen 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 definitely 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.
