[RE-wrenches] Flashings- to nail or not to nail

[North Texas Renewable Energy Inc]

We not only use roofing nails at the bottom corners of metal flashing but
sealant around the top and side edges of the face down side. It keeps
potential water seeping from uphill away from the lag penetration[s]. We
also seal around every shingle edge we pull up or trim off around the
flashing.
In the words of Mark Graham Assoc. Executive Dir of the National Roofing
Contractors Assoc emphasized in his presentation at the AEE conference in
Feb, anything less "...is installing roof leaks."
Yep, it's more work than slapping down L-feet, about 5 minutes per standoff
start to finish, but metal flashed standoffs are the only way we'll attach
PV on 3-tab asphalt roofs. It's often as time consuming finding the rafters
as it is mounting the footings and flashing.

  HI Wrenches:
      My crew wants to nail all the flashings on our footings, but I am
resisting.  Do you guys have any strong feelings about that.
