[RE-wrenches] Reroofing grandfathering

[Mac Lewis]

Hi Howie,

I would ask the AHJ and indicate you are simply reinstalling the system,
not reengineering anything.

I wouldn't take it for granted that the mounting hardware will be usable,
or cost effective to reuse. It's often seized, cross threaded, dirty etc.

There will be a lot of these coming up...

Good luck
