Need to ventilate roof over screened in porch?
I am building screened in porch. The roof will be rafters, with an enclosed ceiling underneath and insulation between the rafters (radiant barrier faced foam). Question is do I need to ventilate this roof? Soffits are no problem, but at top I’d need to use something like cor-a-vent roof-to-wall vent, but not sure it’s necessary since it isn’t going to accumulate moisture like a roof over a conditioned space.
Thanks

There should be some ventilation -- some moisture will get in there. Soffit vents, and maybe some sort of small jury-rigged "gable end" vent. The "ridge" vent would be overkill.
