Will a very heavy rain overflow LeafProof®?
No. When properly installed, LeafProof® will handle the heaviest rainfall ever recorded in one hour in America (11 inches). Rainfall this heavy is an extremely rare and dangerous occurrence. (If it is raining this hard, you will not be concerned about your gutters, you will be wondering if there is any room on the “ark”) In fact, most gutter systems will overflow between 3 to 4 inches per hour. Therefore, manufacturers that advertise their gutter cover can handle 21 inches of rain an hour are misleading because most gutters cannot handle this amount of rainfall.
