Field Test Results of Aluminum Standing-Seam Roofing

摘要

The 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 Defense Construction Supply Center at Columbus, OH. 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 6-month intervals for the next 2 years. Data indicated the roofing system expanded and contracted without restraint, performing as expected. Temperature measurements also indicated that the system reacted to solar radiation and the ambient temperature as expected. Visual observations 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.
