Venting bathroom into attic

bathroom

I have a new house with metal roof no plywood with Ridge vent and soffit venting and has cathedral ceiling. My electricians vented the bathrooms high up into the attic, is that ok?

Electricians are usually only responsible for supplying and installing the fan, not running the ductwork. That is usually done by the HVAC guy or at least another trade or individual. If the electrician has it there contract to run the ductwork fully, then it needs to go to the outside of the house. The water vapor from the bathroom will condense under the metal roof on cooler days and cause water damage elsewhere.
