GAF is North America's largest roofing manufacturer, and its shingles are what Lightning installs on most New Jersey homes. Here's what you actually need to know.
The main lines
- Timberline HDZ — GAF's flagship architectural shingle. Excellent value, strong wind performance, wide color range. The right choice for most NJ homes.
- Timberline UHDZ / AS II — upgraded architectural options with enhanced durability and impact resistance.
- Designer shingles (e.g., Grand Sequoia, Camelot, Slateline) — premium looks that mimic wood shake or slate for high-end curb appeal.
Colors
GAF offers a deep palette — from classic Charcoal, Pewter Gray and Weathered Wood to Hickory and Slate. The right color depends on your siding, your neighborhood, and resale appeal. A good contractor will show you real samples on your home, not just a brochure.
Why GAF certification matters
Anyone can buy shingles, but GAF only lets certified contractors offer its strongest warranties. A GAF-certified roofer (like Lightning) is trained and vetted, which means a better installation and access to enhanced manufacturer warranty coverage you can't get from an uncertified installer.
The system, not just the shingle
A GAF roof is a system: starter strips, leak barriers (ice-and-water shield), underlayment, the shingles, ridge cap, and ventilation — all working together. Installing the full system correctly is what unlocks the long warranties and the real performance. Learn more on our roofing page.
