It's ridiculous that the company that did the roof (and ridge vent) did
not tell the association that the ridge vent is absolutely useless
without a low vent to allow air in. As wind flows over the ridge, it
creates a negative pressure to draw attic air out. Without a way for
new air to get in, the air just sits in the attic. I would seek out a
professional to draft a position letter that you can send to the
association to have them consider retrofitting gable end vents. If they
don't consider doing it in all the units, at least you can make a
better case for allowing YOU to have it done near your own unit.
