CHA has worked on multiple projects at the historic Fort Vancouver National Site in Washington State. The Artillery Barracks (1904) at the Fort Vancouver National Site and a significant example of the military architecture of the era. CHA was engaged for the replacement of roofing surfaces on the main roof and various porch roofs, requiring a high level of care and consideration to protect the building’s historic integrity.
Upon our inspection in 2007, we found poor flashing caused of a number of failures and water intrusion facilitated construction of new roof. Removal of the roofing system also uncovered failures in the built-in gutter system, which lead to new gutters on the entire building. Historic slate shingles were considered on the main roof, but composition roof with a similar look to slate was chosen in response to budget constraints. New metal roofing, the original material on the porch roofs, restored the porches back to their original design intent. New flashing was detailed at all roof penetrations to mitigate water intrusion and existing ventilators were prepped, painted and re-set on the new roof.
In 2008, The Vancouver National Historic Reserve Trust commissioned Carleton Hart Architecture to assess the exterior envelope condition of the Post Hospital Building 614 for purposes of submittal to the 2008 Save America’s Treasures program.
