Armory_Building_Roof_Assessment_by_the_Granland_Company.pdf

This is a comprehensive roof assessment report prepared by the Garland Company for the County of Tuolumne, specifically focusing on the Armory Building located at the Tuolumne County Airport. The report documents a detailed inspection of the 12,000-square-foot roof section, conducted on October 15, 2020, revealing significant deterioration and multiple systemic issues requiring immediate intervention. The assessment recommends a complete roof replacement using a Garland SBS 2 ply membrane system, with an expected 30-year lifespan and a comprehensive waterproof warranty.

The proposed solution includes multiple budget options ranging from $300,000 to $260,000 for a full roof replacement, with additional recommended work such as removing existing roofing and insulation, installing new blocking and sheet metal components, and addressing structural damage discovered during the inspection. The report highlights extensive problems including water leakage, dry rot, damaged soffit and fascia boards, rusted gutters, compromised electrical conduits, and potential structural risks. Additional recommended work includes waterproofing exterior surfaces, asbestos testing, and potential removal of existing roofing materials, with separate budget allocations for testing ($1,000), removal ($60,000), and fascia/gutter replacement ($80,000).
