Roof Eval 2012 Clinic Visual inspection.pdf

This is a Roof Inspection Report (Limited Visual Inspection) dated December 13, 2012, for the Western Oregon Service Unit Chemawa Health Center Clinic (Building #-022) in Salem, Oregon, conducted by A-Tech/Northwest, Inc. for the Portland Area Indian Health Service.

The facility contains approximately 20,142 square feet of single-ply roofing and 4,362 square feet of metal roofing across six roof sections (A, B, C, D, E, and F). The single-ply roofs (Roofs A and B) consist of Duralast hybrid PVC membrane over polyisocyanurate insulation and plywood decking. Roof A is ten years old with an expected life of twenty years; Roof B is five years old (from a 2007 dental addition project) with an expected life of fifteen years. The metal roofs (Roofs C, D, E, and F) are thirty-five years old standing seam construction with an estimated remaining life of five to ten years. The report notes that both single-ply and metal roof systems are currently performing well with manageable conditions, though several maintenance and repair items require attention. Priority 2 (Potentially Critical within one year) repairs include general maintenance and inspection of thru-wall overflow scuppers flashing on the single-ply roofs. Additional repairs needed include replacement of pipe flashing boots on metal roofs, inspection and repair of areas where sharp metal contacts the single-ply membrane, gutter cleaning, and electronic roof moisture study (RMS) testing every five years. Budget estimates for 2013 repairs total $2,500 (labor and materials), with single-ply roof replacement estimated at $180,000 and metal roof replacement at $84,000. The report recommends in-house visual inspections twice annually and professional independent inspections every other year, with the next RMS inspection scheduled for 2016 or 2017.
