During a reroof I had a turbine unstalled in the garage roof along the
southern California coast. It had been about 10° warmer than the
patio slab prior to the turbine and after installation it has been
about 10° cooler. It was surprising to me to find that much
difference. Ensure that the outlets for tools are wired separate from
the lights in the woodshop.

I have a question about venting a garage roof.
I am turning my detached garage into a woodworking shop. I am adding heat
and ac and will thus insulate. I know that a building with an attic space
needs to be vented. However, can I insulate right onto the roof, in other
words, put the insulation right between the joists and right up against the
roof sheeting? Or do I need to make an attic space and vent the roof?
Thanks
