Vented Drip edge

Trapped moisture causes condensation. Condensation that forms inside an attic comes from the use of tubs, showers, washing machines, clothes dryers, dishwashers and boiling water. Moisture causes mold, mildew, and fungi. All this leads to dry rot, which spreads and damages any lumber that is affected. Condensation also causes rust; any uncoated metal will rust over time and eventually deteriorate to the point of failure.
