“I was installing metal roofs on a dairy barn in Southside Virginia that had been converted into an apartment. They were very nice — rustic and beautiful. While installing a sheet of 40-year metal on the lower portion of the roof, my coworker drilled the colored wood screw into the metal, then a loud pop came from the screw and was glowing red.”
“He looked down at his drill like, WTH? Smoke started coming from the ventilation fans on the upper roof above us, and the whole structure ended up being burnt beyond repair. It was a total loss.
Upon inspection by us and the fire marshal, we learned that the electrician (from another company) had majorly messed up. They’d installed the breaker box wrong and ran his wires directly below the old roof along the rafters, violating building codes. It took about 30 minutes for the fire department to arrive at the remote location of the barn. We where just watching this poor woman’s investment burn uncontrollably.”
