Outlets not working after replacing roof

Hi everyone, we just recently replaced our roof and afterwards, 3 out of the 6 outlets stopped working upstairs. I bought a circuit tester to find out if something like a neutral or hot wire came loose. For the outlets that were not working, it showed up the wiring was correct. What's weird is when I have the circuit tester plugged in, and then plug in an alarm clock in the other socket, it switched from correct wiring to hot/grd reversed. When I try this in an outlet that's working, it stays correct wiring on the circuit tester. Any ideas? I'm trying to avoid calling the electrician. Last time I did it was a stupid GFCI that tripped 2 rooms away and I threw away 50 bucks for the service call.

Check for a loose wire where you plugged in the clock.

An analog multimeter would be better to test. Circuit testers can give misleading readings. In addition to checking for loose wires move any backstabs to the screws.

You have an open or very close to open neutral. The slightest load will cause it to open. The part I'm concerned about is what the roof has to do with it.

Was sheathing replaced ?
The wiring shouldn't really be near the roof but if it is.... possibly a nail went thru a cable severing the neutral.

I was thinking the hammering on the roof caused a wire to come loose.

I'm with Pete on this one . Wiring should not be attached to roof trusses but I've seen it done.
