GAF and Owens Corning are the two biggest roofing shingle brands in the United States — together they control over 80% of the residential roofing market. If you're getting a new roof, your contractor will almost certainly offer one of these two. So which one should you choose?
The short answer: both are excellent. The longer answer depends on your climate, your budget, which brand your roofer is certified to install, and what warranty coverage matters most to you. This guide breaks it all down.
Find verified, top-rated roofing contractors in your city who are certified to install both brands.

GAF is the largest roofing manufacturer in North America, headquartered in Parsippany, NJ. Their flagship product — the Timberline HDZ — is the best-selling roofing shingle in the USA. GAF offers shingles across three tiers: Good (3-Tab), Better (Architectural), and Best (Designer/Premium).
GAF's Master Elite program is their elite contractor certification — only about 3% of US roofing contractors qualify. A Master Elite roofer can offer the Golden Pledge warranty: 25 years of workmanship coverage plus a lifetime shingle warranty. This is one of the strongest workmanship warranties in the industry.
💡 GAF Pro Tip: Always ask if your contractor is Master Elite certified. A standard GAF contractor can only offer a System Plus warranty (10 years workmanship). The Golden Pledge requires Master Elite status.
Owens Corning (OC) is GAF's biggest competitor, known for their iconic pink fiberglass insulation and a strong shingle lineup. Their flagship architectural shingle is the Duration Series, featuring their patented SureNail Technology — a woven fabric strip in the nailing zone that creates a much stronger attachment to the roof deck.
OC's top tier is the Platinum Preferred Contractor designation. These contractors can offer OC's best warranty: a 50-year transferable system warranty covering both materials and labor. On paper, this is longer than GAF's Golden Pledge — but the Platinum Preferred network is smaller, so finding one in your area may be harder.
💡 OC Pro Tip: If you're in a high-hail state (TX, CO, MN, IL), ask specifically about the Duration Storm (Class 4 impact rating). It may qualify you for a homeowner's insurance discount of 15–30%.
At comparable price points, both brands perform extremely well. GAF's Timberline HDZ uses LayerLock technology and weighs slightly more than standard shingles. OC Duration uses SureNail with a reinforced nailing strip. Independent tests show both hold up well in severe weather — this category is essentially a tie at the architectural level.
✅ Winner: Tie. Both brands offer comparable quality at similar price points. The specific product line matters more than the brand.
Both brands rate their flagship shingles at 130 mph wind resistance when properly installed. However, OC's SureNail technology is specifically engineered to reduce blow-offs during installation — the woven strip gives nails a better grip even if placed slightly off. GAF's LayerLock also provides strong adhesion but doesn't have the same nailing-zone reinforcement.
✅ Winner: Owens Corning — slight edge in high-wind environments due to SureNail technology.
This is where things get complicated. GAF's Golden Pledge (Master Elite required) offers 25-year workmanship + lifetime shingles. OC's Platinum Preferred warranty goes to 50 years on the full system. On paper OC wins on duration — but both require using certified contractors, and finding a Master Elite (GAF) or Platinum Preferred (OC) contractor in your city affects which warranty you can actually access.
✅ Winner: Owens Corning (50-yr system warranty) — but GAF is close and Master Elite contractors are more widely available.
GAF has the larger certified network. Master Elite contractors number in the tens of thousands across the US. OC's Platinum Preferred network, while high-quality, is smaller. In most major cities you'll find both — but in smaller markets, GAF contractors are easier to find.
✅ Winner: GAF — larger Master Elite network means more access to the best warranty options in more zip codes.
GAF offers 300+ color and style options across their lineup, including designer shingles that mimic slate, wood shake, and tile. OC's palette is strong at 200+ options but narrower at the premium tier. For homeowners with specific aesthetic requirements, GAF has more choices.
✅ Winner: GAF — more options, especially in premium/designer lines.
Owens Corning wins here — their Duration Storm is rated Class 4 (the highest UL 2218 impact rating), specifically designed for hail-prone markets. GAF also offers impact-resistant options (Timberline ArmorShield II), also rated Class 4. If you're in TX, CO, MN, or IL where hail is frequent, both brands have competitive options.
✅ Winner: Tie — both have Class 4 impact options. Ask your contractor which is more available in your market.
⚠️ The most important factor: Neither brand matters as much as the contractor installing it. A GAF Timberline installed by a mediocre roofer will fail faster than an OC Duration installed by a Platinum Preferred pro. Always verify your contractor's certification and check their Google reviews before signing.
| Product Tier | GAF Option | OC Option | Installed Cost (per sq ft) |
|---|---|---|---|
| Good (3-Tab) | Royal Sovereign | Supreme | $2.50–$3.50 |
| Better (Architectural) | Timberline HDZ | Duration Series | $3.50–$5.00 |
| Best (Premium) | Camelot II / UHDZ | Duration Designer | $5.50–$9.00 |
| Impact-Resistant | ArmorShield II | Duration Storm | $4.50–$6.50 |
Find top-rated certified contractors in your city — compare quotes and choose with confidence.
Find Roofers in My City →For most homeowners in most climates, you cannot go wrong with either brand at the architectural (dimensional) shingle level. The real decision should be based on which brand your best local contractor is certified to install at the highest tier — because that determines your warranty coverage more than the brand name on the shingle.
If you're in a hail or high-wind state, give OC Duration Storm a close look. If you want the widest contractor network and the most color options, GAF is the safer bet. Either way, get at least 3 quotes from certified contractors before signing.
