I am in the process (day1 of 2) of getting a new roof. I have a whole house fan - Louvered ceiling type. House was built in 1968 so I have no spec on that fan. It has (or had after they ripped it out) a roof ventilator with fan. The roofers removed the “mushroom” bowl shaped thing on roof and disconnected the fan from electricity.
They are telling me I don’t need it anymore because they are putting on a ridge vent. Currently I had this ventilator and 5 turtle type vents.
Are they correct not to put the mushroom ventilator back and hook it back up?
