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

[Nick Soleil]

OK, even though the solar racking manufacturers do not detail nailing the 
flashings to the roofs in their installation manuals and on-line videos, Oatey 
does publish a document which says "One nail or staple in each bottom corner is 
appropriate."

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.
