At the rake (gable) edge of a shingle roof, the drip edge should be installed:
a.Over the top of the underlayment
b.Under the underlayment
c.Only where gutters are present
d.Behind the fascia board only
Giải thích
At rakes the drip edge is installed over the underlayment, while at the eaves it goes under the underlayment; this layering directs water off the edge correctly. Restricting it to gutter locations or behind the fascia does not meet the requirement.
