T-Style Perimeter Edge Flashing
Until recently, snow-belt states were the only ones that required drip edge.
That’s because ice backup caused by melting snow exposed the flashing point – allowing water to penetrate the rafter tails, insulation, fascia and soffits. Because of concerns regarding mold, however, many building code writers in the rest of the country – especially the south – have also adopted the drip edge requirement.
