You need to do some research. If there is actual airflow through the roof/ceiling then there also will be water - or the potential for it and that’s very bad! I’d wander around with a lit candle on a windy day and see if there is any flicker of wind. If so get to the outside of the area and inspect it very carefully so that you can seal up any suspect areas. Too few people know that you need to inspect and reseal at least a couple of times a year. I do it every few months and rarely fail to find something to address. Catch it early!!
