A Century of GAF Roofing Shingles
GAF didn’t just join the shingle business. It helped invent it. According to GAF’s own history, the company introduced individually cut asphalt shingles in 1912, and today it’s North America’s largest roofing manufacturer.
7 Reasons Homeowners Choose GAF Roofing Shingles
Here’s why more Miami Valley homeowners pick GAF, with the rating, warranty term, or test behind each one.
Hail is hard on Ohio roofs. GAF shingles like Timberline® AS II and Grand Sequoia® AS earn the UL 2218 Class 4 rating, the highest impact rating for asphalt shingles, which can help with insurance discounts where insurers offer them.
Dura Grip™ adhesive seals each shingle to the one below. With LayerLock™ shingles and four qualifying GAF accessories, the WindProven™ limited wind warranty carries no maximum wind speed.
LayerLock™ mechanically fuses the shingle layers and adds the wide StrikeZone™ nailing area. GAF reports up to 99.9% nailing accuracy in controlled testing, which matters most when gusts hit.
StainGuard Plus™ protects against the blue-green algae streaks that age a roof early, backed by a 25-year limited algae warranty on qualifying products.
Timberline® shingles carry a UL Class A fire rating, the highest there is, a quiet benefit most homeowners never think to ask about.
These shingles work with matching leak barrier, roof deck protection, starter strips, ridge caps, and ventilation. Installed together, the system unlocks the strongest warranties.
GAF introduced individually cut asphalt shingles in 1912 and is North America’s largest roofing manufacturer today. That’s a long track record on real roofs.
Which GAF Roofing Shingles Fit Your Home?
GAF makes dozens of products, but most Miami Valley roofs come down to four choices. Here’s how we explain the lineup at the kitchen table.
Timberline HDZ®
GAF’s best-selling shingle and the right answer for most homes. LayerLock™ Technology, the wide StrikeZone™ nailing area, and WindProven™ eligibility in a classic dimensional look.
Timberline UHDZ™
A thicker shingle with a dual shadow line for deeper, richer dimension. A favorite for homeowners who want the roof to carry more of the curb appeal.
Timberline® AS II
Class 4 impact resistance from SBS-modified asphalt that flexes instead of cracking. Rated Good in IBHS lab hail testing, and a strong fit where hail claims are common.
Grand Sequoia®
Oversized, wood-shake character with bold shadow lines. The ArmorShield™ version adds Class 4 impact resistance for homeowners who want both looks and toughness.

GAF Roofing Shingles Work as a System
Tap a layer to see what it does. Top of the stack is the top of your roof.
Seal the peak and finish the look. GAF ridge caps are matched to your shingle color.
The weather surface: impact, wind, fire, and algae protection in one layer.
Lock down the first course at the eaves and rakes, where wind uplift starts.
A synthetic underlayment that adds a second barrier against wind-driven rain.
Self-adhering protection in valleys and along eaves, where ice dams form in Ohio winters.
Balanced intake and exhaust that keep the attic dry and help shingles last.
Shingles are only the visible layer. GAF roofing shingles reach their full potential when every layer underneath comes from the same system, which is also what qualifies a roof for GAF’s strongest warranties.
Why Installation Decides Long-Term Performance
Even the best shingle on the market can’t survive a bad installation. These are the details that separate a roof that lasts from one that leaks early.
- Nail placement. Nails belong in the manufacturer’s nailing zone, driven flush. High or overdriven nails are a leading cause of blow-offs.
- Starter strips at every edge. Without them, the first course has no sealant where wind uplift begins.
- Leak barrier in the valleys and eaves. That’s where water concentrates and Ohio ice dams form.
- Balanced ventilation. A hot, wet attic shortens the life of any shingle from underneath.
- A certified contractor. GAF’s enhanced warranties, like the Golden Pledge®, are only available through GAF-certified contractors.
Compare coverage options on GAF’s residential warranty page, then ask any contractor which tier they can actually register.
