How can I stop particles from entering building with high ceilings?

I have been struggling for quite a long while now when it comes stop the weather particles from entering my building.I had discovered an odd situation that I hope someone will be kind to help me to figure how to solve. Okay, the situation I discovered is that when I enter my building, it seems that the particles from the rain or snow and such will enter the rooms ONLY with the high ceilings in them. The rooms with the lowered ceilings seems to work as I want them to work, with no particles entering in. I did discover that in the rooms with the high ceiling is if I place a lower ceiling as high as the balcony, the particles will not enter the area. If I happen to remove the lowered ceiling I added, the particles will start again. Another odd part is, if I go up top of the balcony, the particles will again stop. I can even walk under a balcony and the particles will not go under them but will go around them. How can I get it to where the particles will not enter with the high ceilings?

Check the speed of the particles and the thickness of the colliders on the roofs. Some of the particles might be too fast and they pass through without causing a collision PrepaidCardStatus

BUMP Does any one have any solution to my issue yet?

Thank you for the kind response and most grateful. I have checked into that part already. I do not realize that I had forgotten to mention that the system is attached to the players camera as well. Sorry for missing that part.
