Why do you need two electricians for a week? My rooftop solar array went up in an afternoon. They had three labourers. The (singular) electrician came in separately and worked for under and hour.

reroofing means disassembling and reassembling. You need to deconstruct, put the new roof on, then add the solar back.

The quoted cost of wasn't for the re-roofing, it was in addition to the re-roofing:

Since all of the scaffolding or whatever is already up for the roof work, if anything the solar ought to be cheaper, in that scenario.
