1. Regional Microclimate Dynamics & Severe Storm Exposure in Boise
The Treasure Valley experiences intense wind patterns resulting from severe atmospheric pressure gradients between the high desert of Eastern Oregon and the Rocky Mountains. Wind gusts accelerating out of the Boise Foothills and across the open plains of South Meridian and Kuna regularly exceed 60 to 70 MPH. These powerful aerodynamic uplift forces get beneath loosened shingle edges, peeling entire courses off the roof deck. Once the structural underlayment is torn away, torrential rain saturates the plywood sheathing, causing rapid delamination and creating immediate entry points into living spaces below.
