So I’ve had a first and would like some input. I’ve been in this business a good amount, handyman, electrical and machinery troubleshooting, as well as volunteer fireman for many years but haven’t experienced this. I was inspecting a roof deck from the attic and the nails weren’t there and scorched sheathing where they were along the top 1/3 of the roof. There was snow and ice on the roof, so I wasn’t to examine the roof.
My thoughts move to lightning passing through the shingles and zapping the nails. Has anyone ever heard or experienced this?
