In structural failure analysis of steep-slope roofing systems across coastal peninsulas, one component fails out of sight long before the shingles themselves degrade: the mechanical fastener. A standard architectural shingle relies on an array of 4 to 6 pneumatic nails driven into a structural deck to secure against cyclonic uplift forces. However, across coastal zones—such …
