Our History

About Us: A.B. Martin

It was a small beginning in 1947 when Amos B. Martin began selling metal panels to his Lancaster County neighbors for their chicken shelters.  Fast-forward 75 years and A.B. Martin Roofing Supply is one of the fastest-growing building supply companies in the Northeast.  Over 19 million feet of metal panels come off our machines each year.


Today, A.B. Martin is your one-stop-shop for all things building related.


Serving Pennsylvania, New York, Maine, Vermont, New Hampshire, Connecticut, Massachusetts, Rhode Island, New Jersey, Delaware, Maryland, Virginia, West Virginia, and the surrounding states.
