Largest Roofing Companies in the US
The largest roofing companies in the United States include national commercial roofing contractors such as Tecta America, CentiMark, Nations Roof, and Baker Roofing, alongside major roofing material manufacturers like GAF and Owens Corning. The roofing industry's most-cited annual ranking is Roofing Contractor magazine's Top 100, which ranks contractors by annual revenue. This page explains the largest national players and how the rankings work — and, for homeowners and building owners, how to find a top-rated roofer in your own city.
The US roofing market was valued at over $70 billion in 2025 and continues to grow, driven by aging housing stock, new construction, and extreme weather. Most of that work is performed by tens of thousands of regional and local contractors, with a small number of large companies operating nationally.

Largest Roofing Material Manufacturers
"Largest roofing companies" sometimes refers to the manufacturers that produce roofing materials rather than the contractors who install them. The biggest North American roofing manufacturers include:
- GAF — The largest roofing manufacturer in North America, known for asphalt shingles and commercial systems.
- Owens Corning — A leading manufacturer of shingles, insulation, and roofing components.
- CertainTeed — A major manufacturer of residential and commercial roofing products.
- Carlisle SynTec and Holcim Building Envelope (Elevate, formerly Firestone Building Products) — Leading manufacturers of commercial single-ply membranes including TPO and EPDM.
- IKO, Atlas Roofing, TAMKO, and Malarkey — Major shingle and roofing-product manufacturers.
How the "Top 100" Rankings Work
The industry-standard list is Roofing Contractor magazine's annual Top 100, which ranks roofing contractors primarily by annual revenue, along with breakdowns by residential, commercial, and re-roofing volume. Other organizations, such as the National Roofing Contractors Association (NRCA), publish industry data but not a single definitive "largest" ranking. Because revenue, acquisitions, and private-equity consolidation shift the standings every year, treat any specific rank as a snapshot in time.
Finding a Top Roofing Company Near You
For most homeowners and building owners, the best roofer is a highly rated local contractor — not necessarily a national giant. Large national companies excel at multi-site commercial portfolios, while local specialists often provide better pricing and service for a single home or building.
