[RE-wrenches] Bonding Metal Roofs Part II

[AE Solar]

Hey all,
I had started a thread about bonding to metal roofs in 2018 but can't
figure out how to respond via the archive. I know some things have changed
since then, so I'm circling back and starting a new thread.

In NY one of our inspection agencies (NYSERDA) requires bonding of metal
roof panels below the array, as well as within a 3' perimeter of the array.
S-5! in combination with Ironridge is now listed to bond the roof under the
array (so long as you hit every pan with an attachment) but this doesn't
solve the problem of trying to bond within the 3' perimeter. For installs
where we are only 18" from the ridge, this means we are required to bond
the adjacent roof as well.

Whenever possible we install Illsco SGB-4 lugs under the ridge cap. But
more and more we're finding roofs where the ridge cap feels inaccessible,
tricky, or where we simply don't want to get into roof warranty issues
associated with opening up a prior contractor's work.

Wondering if anyone else is coming up against this and what some possible
creative solutions might be. I don't want to walk away from potential
projects but...

As always, thanks for any thoughts
Adam
