Investigation of the Corrosion of Aluminum Standing-Seam Roofing at an Army Facility

摘要

An investigation was conducted to determine the extent of corrosion of an aluminum standing-seam roofing system exposed to weathering over a period of nearly three years. The aluminum roofing was installed on three large warehouses at an Army facility in Columbus, Ohio. A high performance elastomeric sealant was used in forming the standing seams of the roofing system. The roof slope, about 5 percent, was less than that usually recommended for unsoldered standing-seam roofing. The roofs were located in a region having a high level of acid rain.
