A.B. Martin Roofing Supply had a very small beginning in 1947That's when Amos B. Martin started selling metal panels to his Lancaster County neighbors for their chicken shelters. Through hard work and honest service we’ve steadily grown. And today, though we’re blessed to be one of the largest metal roofing suppliers in the Eastern United States, we have never forgotten the early days and the people that helped us grow to where we are today. That’s why we started a wholesale division with some of the most popular and needed products for roll-forming operations and building supply retailers like you. We want to support you in your business and share our top-tier and high volume pricing with you.
