Until recently, only snow-belt states required drip edge to prevent issues with ice backup caused by melting snow, which exposed the flashing point—allowing water to penetrate the rafter tails, insulation, fascia and soffits.
More recently, many building code writers in the rest of the county—especially the south—have also adopted the drip edge requirement to help guard against wood rot. And Quality Edge brings smart, innovative perimeter flashing solutions to every project you deliver.
