Defending the Gable: Engineering Rake Edges Against Cyclonic Vortex Shedding

In sloped roof forensics, catastrophic storm failures follow a predictable aerodynamic path. Long before mid-slope field shingles lift or primary trusses deflect, structural damage almost universally originates at the perimeter boundaries—specifically, the sloping gable ends, known in construction engineering as the rakes. While horizontal eaves receive water discharge from downhill sheet flow, the sloping rakes …
