Best Answer

To prevent dead birds, leaves or other objects from entering the storm leader and causing a blockage and risking the building to collapse from the weight of water accumulation.

Also a dome type cover is the best choice as the beehive type even with debris around the base will still allow drainage from the top of the dome
