Conduit Under Roof Deck

Is there a conduit finder out there that we can use to trace conduit under a roof deck?

Re: Conduit Under Roof Deck

I've used my cable tracker to trace out conduits. I had to hook on the wire(s) in it though.

I doubt a roofer is willing to deenergize circuits and work in live panels in order to use a locator. He's more likely thinking there is a miraculous device that gives him x-ray vision to peer below a flat roof that has a corrugated deck below it.

Looking to find the conduits so he can run some screws into them and have the electrical side start to pick up?

It might have something to with the continuity between the EMT and the trusses/deck pan...and everything else metal in the building [it's all bonded together]

Never thought of that.
Never thought of this particular
problem either though.

Re: Conduit Under Roof Deck

See this thread on ElectricianTalk. It happens from time to time, and I think the only tool that any roofer has to avoid it is luck and a decent insurance policy. I think it's fair to say that if you do flat roofs, this is going to happen from time to time.

Re: Conduit Under Roof Deck

This job is in a Milk plant and the conduit is run every where. Instead of having a man stand below all day with a radio we were hoping to trace them above the deck and save some time.
