Where Are Roofing Shingles Made?
The vast majority of asphalt roofing shingles sold in the United States are manufactured domestically. The three largest manufacturers — GAF, Owens Corning, and CertainTeed — operate dozens of plants across the country, producing billions of square feet of shingles annually. This domestic production means shorter supply chains, faster delivery, and regional availability that keeps costs competitive.
- GAF is the largest US shingle manufacturer, with plants in over 20 states.
- Owens Corning operates major manufacturing facilities across the US and internationally.
- CertainTeed (a Saint-Gobain subsidiary) manufactures at multiple US locations.
- IKO and Atlas are additional major manufacturers with US and Canadian plants.
- Most shingles travel 200–500 miles from factory to your roof — regional production keeps shipping costs low.
The Big Three Manufacturers
GAF — headquartered in Parsippany, NJ, GAF is the largest roofing manufacturer in North America. They produce shingles at plants in states including Texas, California, Michigan, Georgia, Maryland, and many others. GAF’s Timberline series is the best-selling shingle in the US.
Owens Corning — based in Toledo, OH, Owens Corning manufactures shingles alongside their fiberglass and insulation products. Their Duration and TruDefinition lines are widely available. Plants operate across the US, including facilities in Texas, Georgia, California, and Minnesota.
CertainTeed — a subsidiary of French conglomerate Saint-Gobain, CertainTeed is headquartered in Malvern, PA. Despite the French parent company, their shingles are manufactured in the US at plants in multiple states. The Landmark series is their flagship product.
Why Manufacturing Location Matters
Supply chain speed: Regional manufacturing means your shingles don’t travel across an ocean. In most markets, materials arrive within days of ordering, not weeks.
Quality consistency: US manufacturing facilities operate under strict quality control standards. Each plant is audited regularly, and shingles are tested to meet ASTM standards and local building codes.
Warranty service: A domestic manufacturer with local distribution means warranty claims are handled faster. If you need a replacement under warranty, the supply chain is short and responsive.
What Shingles Are Made Of
Modern asphalt shingles are a layered product: a fiberglass mat core provides structural strength, saturated with asphalt for waterproofing, and coated with ceramic-coated granules for UV protection, fire resistance, and color. The raw materials — fiberglass, asphalt, limestone granules — are all domestically sourced in most cases.
Frequently Asked Questions
Are any roofing shingles made in China?
Very few asphalt shingles sold in the US are imported. The weight and bulk of shingles make overseas shipping impractical. Nearly all shingles on US roofs are domestically manufactured.
Which shingle brand is made in the USA?
GAF, Owens Corning, CertainTeed, Atlas, and TAMKO all manufacture in the United States. IKO manufactures in both the US and Canada.
Does it matter where my shingles are made?
For most homeowners, no — all major brands meet the same ASTM performance standards. What matters more is installation quality. A GAF-certified crew installing GAF shingles gives you the strongest warranty package, which is why Roofana uses GAF-certified crews exclusively.
