Mahan Slate Roofing has been in business since 1979 and has evolved into one of the premier slate and copper roofing companies in the New England region. We pride ourselves on our knowledge of slate and copper roofing, and continue to study and train to keep our skills current. To ensure we have the most current understanding of the industry, we work closely with The Slate Roofing Contractors Association, (where John Mahan is a current board member), The National Slate Association, The National Roofing Contractors Association and The North East Roofing Contractors Association.
