Abstract
The overall objective of this project was to determine the behavior of aluminum standing-seam roofing over two annual cycles and to evaluate its capacity for long-term, trouble-free performance. The roofing system was installed on three warehouses at the Defence Construction Supply Center (DCSC) at Columbus, Ohio. Thermocouples and gage points were installed to measure surface and substrate temperatures, expansion, contraction, and lateral deflection. Measurements were taken at the time of installation and at six-month intervals for the next two years. Data indicated the roofing system expanded and contracted without restraint, performing as expected. Temperature measurements also indicated the system reacted to solar radiation and the ambient temperature as expected. Visual observation indicated that many important details of flashings and connections were deficient in design, fabrication or both. These should be corrected for the system to function properly.
