Owens Corning vs. GAF: A Comprehensive Comparison

Owens Corning and GAF stand as two giants in the roofing industry, competing alongside other reputable names like CertainTeed, Malarkey, Atlas, IKO, and TAMKO. While GAF claims the title of the world’s largest roof and waterproofing manufacturer, Owens Corning stands out for its exceptional quality and durability. Let’s take a look at how they stack up, head to head in the places that matter:

  • Shingle Quality 
  • Price
  • Shingle Variety
  • Warranty 

Shingle Quality

High-quality shingles excel in critical areas such as wind and storm damage resistance, fire resistance, layers of material, and shingle weight. Both Owens Corning and GAF shingles boast a commendable wind resistance of up to 110 mph, with the potential to reach 130 mph through upgraded installation techniques. Both brands also secure a Class A fire rating, signifying top-tier fire resistance.

When it comes to shingle material layers, Owens Corning offers a competitive four to five layers, outperforming GAF’s three to four layers. While the weight of a shingle is often debated among professionals, Owens Corning takes the lead, with most products weighing more than 250 lbs per square, providing enhanced protection against wind and hail.

What this means for your home is that the wind can blow, the heat can blaze, but an Owens Corning shingle is going to protect all the things you love under one roof.

Owens Corning sets itself apart as a premium shingle brand, offering top-quality products that reflect its slightly higher price point. GAF, known for its affordability, shines in this category with more cost-effective options. Whether comparing 3-tab, architectural, or designer shingles, GAF generally proves to be the more economical choice. However, the price difference between the two is not overly significant that it outweighs the value of either.
