Comparing GAF HDZ to Other Shingle Types

I’ve seen my fair share of shingles over the years, and I can tell you that GAF HDZ shingles are in a league of their own. They blow traditional 3-tab shingles out of the water in terms of aesthetics and performance.

Even compared to other architectural shingles, HDZ® shingles stand out. The high-definition look is unmatched, and the advanced technology ensures they’ll stand up to whatever Mother Nature throws their way.

GAF HDZ Shingle Technology

Let’s get geeky about the technology behind these shingles – it’s seriously fascinating stuff.

LayerLock Technology Explained

LayerLock™ Technology is like the superhero of shingle tech. It fuses the common bond between overlapping shingle layers, creating a mega-shingle that can handle wind speeds up to 130 mph. That’s Category 3 hurricane-level wind, folks.

WindProven Limited Wind Warranty Details

Speaking of wind, the WindProven™ Limited Wind Warranty has your back. When you install HDZ shingles with the required number of nails and GAF starter strip shingles, you’re covered for winds up to 130 mph. That’s some serious peace of mind.

DuraGrip Adhesive for Superior Hold

But wait, there’s more. DuraGrip™ Adhesive is like the cherry on top of this shingle sundae. This proprietary sealant grips tight to your roof deck, keeping your shingles in place no matter what. It’s the unsung hero of GAF HDZ shingles.

GAF HDZ Shingle Warranty and Protection
