Drip-Edge Details
To the Editor:
In the drawing showing the nailing
requirements for asphalt shingles (On
the House, 8/00), I noticed that you
show the felt underlayment installed
over the metal drip edge on the rake
edge of the roof. I believe that the
Uniform Building Code, and most manufacturers,
require the drip edge on the
rake edge to be installed over the
underlayment. Am I missing something,
or was it drawn wrong?

Harrison McCampbell responds: The
Uniform Building Code, like the CABO
code and the other model codes, simply
requires all flashing to be installed "as
per shingle manufacturer's printed
instructions." When you look at any
of the manufacturer's instructions or
recommendations, they may show metal
drip edge
