The challenge
Thousands of failed fasteners and a production line that could not stop for more than one planned weekend.
Our approach
- Engineer-reviewed zee framing over existing purlins
- Old roof left in place as debris barrier
- New insulation added in the retrofit cavity
- Exhaust stacks re-flashed with PVC-coated metal
