Roof Executive Summary: <br />Roof Areas A, B, C, F & G consist of a fully adhered single ply "EPDM" roof system with tapered <br />insulation installed in 1997. Drainage on all roof areas is accomplished with interior drains and/or <br />scuppers. The roofs are generally in fair condition and have many high level deficiencies that will or have <br />let water into the roof system or building interior. These defects should be repaired immediately by a <br />qualified roofing contractor to minimize the potential of further water infiltration. These roofs should <br />perform as intended for another 5 + years with annual roof repairs. <br />Roof Areas D & E consist of a metal roof installed in 1971 (See separate investigation report performed <br />by SBEC). <br />Roof Area H consists of a single ply "TPO" roof with tapered insulation. (Roof not included in <br />investigation). SBEC did observe temporary rubber repairs at the roof scuppers which do not meet <br />standard roofing practices. The repairs should have been made using "like" materials and properly heat <br />welded. The "TPO" membrane appears to be adhered to the existing scuppers. The existing scuppers do <br />not appear to be coated to allow the "TPO" membrane to be properly heat welded to the scuppers. We <br />were advised that the original roofing contractor had implemented the rubber repairs at the scuppers. The <br />contractor should return and provide proper heat welded "TPO" repairs at the scuppers at no cost to the <br />City of Elk River. We also observed some areas where the membrane has become un-adhered at the <br />perimeter wall. These areas should be monitored to determine if the condition worsens with time. SBEC <br />would be willing to meet with the original roofing contractor to discuss our findings.
