Skylight Not Sealed

My skylight isn’t just drafty: On windy days (like today) an almost-constant stream of random sediment “rains” in to the apartment. When it snows outside and is very windy, it also snows in my kitchen. And on windy spring days, I sometimes get flower petals! The last part is nice, but overall I would like to fix this, and the roofer who recently redid the roof claimed that he saw no problem with the skylight. Does anyone have any ideas about what I should do? (I live in a co-op.)
