Corrosion of galvanized steel roof deck <br />Corroded roof deck was located on the outside of the building roof. An investigation of <br />the underside of the decking in these areas did not reveal any corrosion. This issue <br />should be remedied prior to the re-roofing of the facility. Because the corrosion is <br />primarily limited to complete deck panels these could be replaced with the surrounding <br />corroded areas being painted with a galvanic paint. Painting of the entire area may also <br />be an option but more research should be conducted to assure the correct method of <br />repair is specified. <br />The above pictures note the extent of corrosion on the roof exterior and some previously <br />patched roof deck. <br />
