Abstract
This paper uses finite element analyses to examine the change in wind resistance due to two application methods. These are the standard diagonal installation, where the shingles are installed diagonally up the slope with four nails in each shingle, and the racking method, where the shingles are installed in a zig-zag fashion, that often results in one layer being fastened with four nails per shingle, and the next layer having three nails per shingle. The finite element analysis results are testing using our wind tunnel. Other new tests for shingles are discussed, including digital fluoroscopy to investigage blistering, compared to the blistering test proposed in European shingle standards.
