Giải thích
A drip edge is metal flashing at the roof edge that guides runoff off the sheathing and fascia and into the gutter, preventing water from wicking behind the edge and rotting the wood. It does not change slope, is not primarily a fastener for underlayment, and does not ventilate the attic.
