The argument is simple: sequencing the roof first, with the roofing company and the solar crew sharing one calendar, deletes a four figure removal and reset bill before anyone incurs it. Panels and their conduit stay energized in daylight even when the house breaker is off, so disconnecting, lifting or removing modules belongs to a licensed electrician or the solar contractor, working alongside the roofing crew. SquareDash looked at this in April 2026 and put the extra cost of removing and reinstalling panels at $3,000 to $6,000 when a roof needs replacing within five to ten years of the solar install.
