15. What are the top shingle manufacturers?

Some of the top shingle manufacturers in the United States are CertainTeed Roofing, GAF, IKO, Malarkey Roofing, Owens Corning, and Pabco Roofing Products. They all offer great products and have been producing shingles for many years. Some brands are more common in certain areas of the country. Some roofing contractors have certifications with certain shingle manufacturers and can offer extended warranties, that is why they recommend specific shingles.
