Have the roofers plug one piece of equipment in at a time until the
gfci trips.
You will find out which tool has the leakage current to ground that way
and perhaps save them a nasty shock.

Our electrical wall plugs went dead suddenly when the roofing crew tried
to run its equipment off of our outside plug. Do we have to call in an
electrician? All of the switches in the circuit box are on. And
pressing the reset button in the electrical plug unit in the downstairs
bathroom doesn't have any effect. Thanks for any advice.

I tried turning the circuit breakers off and on without success. Then I
tried pushing the reset button of the GFCI box but the reset button
would not stay pushed in. Finally I went outside and unplugged the
equipment that the roofers had plugged into an outside box. Then I was
able to push in the GFCI reset button and now all of the wall plugs
work. Can anyone explain what was causing the circuit break? Thanks.
