A drip edge at the eaves and rakes of a shingle roof functions primarily to:
a.Direct water away from the fascia and into the gutter, protecting the roof edge
b.Increase the slope of the roof
c.Hold the underlayment in place during high wind
d.Provide attic ventilation at the edge
Explanation
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.
