Weird that the inspectors don’t know; ventilation is pretty well the only thing explicitly in the model code as far as sloped roofing goes, and my experience has been that they enforce it enthusiastically as it doesn’t require them to actually go on the roof and look at anything!
Florida goes it’s own way on building codes, but they still kinda keep pace with the IBC, and it says:
Section 1203.2 Attic spaces
The net free ventilating area shall not be less than 1⁄300 of the area of the space ventilated, with 50 percent of the required ventilating area provided by ventilators located in the upper portion of the space to be ventilated at least 3 feet (914 mm) above eave or cornice vents with the balance of the required ventilation provided by eave or cornice vents.
That said, if you have a lot of wind-blown rain and/or a lower slope roof, ridgevent may not be the best idea, and some low profile roof vents or an attic fan (best plan) might be a better way to meet code. This will also be easier for your roofer to accomplish at this point, so you might get more cooperation there…
