Tri-State installs new copper roof on historic Ohio basilica.


We are proud to share this progress photo of The Basilica of Saint Mary of the Assumption in Marietta, Ohio.

Completed in 1909 as St. Mary Catholic Church, it was decreed the 76th basilica in the United States in 2013 in recognition of its historic significance and artistic splendor.

Experienced with the special challenges and responsibility of re-roofing and repairing treasured historic buildings, Tri-State was chosen to replace the 1992 asphalt shingle roof installation with a beautiful copper roof and built-in gutters.
