Leak Investigation Summary: <br />Based on our observations and water testing, the primary cause of leakage occurring along the ridge of the <br />1971 ice arena is due to the open gaps between the foam closure piece and metal panels at the ridge cap. The <br />previous attempts to stop the leakage by sealing around the foam closure piece and extending out the ridge <br />cap have failed. Other leakage may be associated with sealant failure at the metal seams and/or fasteners. <br />The metal roofs are in good physical condition with small areas of minor surface rust. A few of these areas <br />have been painted. We believe that the existing metal roofs can last another 15-20 years with recommended <br />permanent repairs and do not have to be replaced. We recommend performing long term repairs which <br />include removing the sealant from the roof fasteners, sealing the existing seams at the metal laps between <br />panels, installing spray foam at the ridge cap and eves to seal between the ridge cap and metal panels and <br />the metal panels and walls at the eves, and install an Elastomeric Roofing Membrane over the entire metal <br />roof area. This should extend the expected life of the building an additional 15-20 years with periodic <br />maintenance. <br />SBEC has recommended and performed these repairs on similar roofs and have been very successful in <br />extending the service life of the existing metal roofs and saving the owners substantial amounts of money. <br />The Transportation Building in Eden Prairie had the same repairs completed in 2005 and is continuing to <br />perform without any issues and is expected to perform as intended for many years to come. <br />Some of the water issues may stem from condensation due to occupancy, air flow and existing mechanical <br />systems. Our review does not include a study of the existing mechanical systems. These issues should be <br />looked at after the roof repairs have been completed to separate the water infiltration due to the roof itself, <br />and possible condensation issues. <br />Based on our observations and water test, we believe a large portion of water infiltration is related to the <br />performance of the existing roof components and repairs should reduce the moisture issues significantly <br />with completed repairs. <br />Remarks: <br />This is a summary of our visual inspection of the roof and wall systems on the 1971 original ice arena <br />building. We recommend repairing the defects identified in the above report and to perform roof inspections <br />once a year to extend the life of the roof systems. SBEC is currently obtaining estimated costs to perform <br />repairs on the defects identified. We will forward the cost estimates once we receive them and will meet <br />with the City of Elk River to go over the repair costs and discuss possible repair scopes and phased roof <br />repairs if necessary. <br />20 <br />
