Do not leave raw indoor hardware exposed on a roof and hope paint later fixes it.
Check
Check if rods, nuts, washers, strut, and clamps are all exterior-rated.
Look for pitting, red rust, thread loss, or staining.
Confirm rooftop/environment exposure.
Replace hardware before loading worsens.
Protect cut ends and touch-up coating where approved.

Say this to your foreman
The rooftop hanger rods at [location] are already rusting/pitting. I checked the support material. Do you want exterior-rated hardware installed before this line stays permanent?
