Owens Corning vs. CertainTeed vs. GAF: Which Brand Is Best for Pittsburgh?
CertainTeed, GAF, and Owens Corning are the three dominant asphalt shingle brands in the Pittsburgh market, and all three manufacture high-quality products. The critical difference is not the shingle itself — it's the warranty program available through certified installers. CertainTeed's SureStart PLUS covers both materials and labor. GAF's WindProven and System Plus offer competitive coverage. Owens Corning's Platinum Protection warranty is excellent for Duration shingles. In Pittsburgh, Pittsabana installs and certifies CertainTeed, giving access to the SureStart PLUS warranty unavailable through non-certified contractors.
Shingle Performance Comparison for Pittsburgh's Climate
All three brands manufacture architectural shingles rated for Pittsburgh's climate demands. Here's how the primary product lines compare on the specs that matter most in Western Pennsylvania.

- GAF Timberline HDZ: 130 mph wind | Class 4 impact | 210 lb/square | Scotchgard algae protection

Warranty Comparison: The Most Important Differentiator
Shingle warranties are complex, and the fine print matters significantly for Pittsburgh homeowners. Here's how each brand's warranty structure compares for certified contractor installations.
- CertainTeed SureStart PLUS (via certified installer like Pittsabana): 15 years full coverage (materials + labor) + lifetime limited shingle warranty
- GAF System Plus (via Master Elite contractor): 10 years materials+labor + lifetime shingle limited warranty
- Owens Corning Platinum (via Preferred Contractor): 10 years materials+labor + lifetime limited warranty
- Non-certified installation (any brand): Materials only — NO labor coverage. Installation errors are your cost.
- Bottom line: The installation certification matters as much as the brand
Why Pittsabana Chose CertainTeed for Pittsburgh Homeowners
Pittsabana evaluated all three major brands before selecting CertainTeed as our primary product line. The decision was based on warranty depth, product innovation for Pittsburgh's climate, and the factory training program that keeps our crews current.
- 15-year SureStart PLUS labor+materials warranty is the best available in the Pittsburgh market
- StreakFighter algae resistance is built in as standard — not a premium upgrade — critical for Pittsburgh's humid summers
- CertainTeed's factory training requires annual renewal — our crews use current installation techniques
- Max Def color technology delivers superior curb appeal that homeowners consistently notice
- Fewer than 15% of Pittsburgh roofers hold active CertainTeed certification — it's a genuine differentiator
Frequently Asked Questions
Is CertainTeed better than GAF in Pittsburgh?
CertainTeed and GAF are both excellent manufacturers. CertainTeed's advantage for Pittsburgh homeowners is the SureStart PLUS warranty (15 years labor+materials vs. GAF's 10 years), and Pittsabana's CertainTeed certification ensures warranty validity. The shingle performance difference is marginal — the warranty structure and certified installation are where CertainTeed wins.
Does Pittsabana install GAF or Owens Corning shingles?
Pittsabana's primary product line is CertainTeed because our CertainTeed certification activates the SureStart PLUS warranty — the best labor+materials warranty in Pittsburgh.
