Total Building EnvelopeThe Daimler/ Western Star Truck Plant project was the largest roofing job Flynn Portland has completed to date. This 484,000 square foot project came along with complications that stemmed from working on a building that had been expanded to over six times its size since its original construction in the 1960s. Flynn was tasked with this roofing job that was “well overdue” and was experiencing several leaks.
HUNDREDS OF THOUSANDS OF SQUARE FEET OF ROOFING
Aside from the sheer size of the project, Flynn was challenged with adding the weight of a new roof on an aging structure that was already stressed.
Crews had to build a load chart to ensure that materials were placed on structural girders in order to avoid putting stress on the building. Flynn began with preparing the existing metal panel roof system which needed to be sprayed with a urethane foam overlay while removing any loose foam and coating.
Crews were challenged by a thick green slime coating that had been applied to the original roof to mitigate leaks the client was experiencing. The simple task of walking across the roof was complicated by this coating and winter weather, and Flynn had to use 1,000’s of feet of catwalk to navigate the site safely. These catwalks had to be repositioned regularly, and pathways needed treading to help crew members safely maneuver around the job site.
