We installed gutter helmet on our eavestrough to help with leaves and snow sliding off the steel roof. Basically a contoured cap that directs snow and debris off the roof and directs light and moderate flows of water into the eavestrough below. So far the eavestrough haven't bent in the 5 years they've been up, but the installers extended the eavestrough under the eave of an adjoining roof for the dormer over the front door creating a short length that water never runs into. Sounds innocent enough, until the birds started nesting there. Now from nest season until the hatchlings leave, the wall below is splattered with bird droppings. I can't get in to clean the nest material out because there is less than 1/2" between the lip of the eavestrough and the lowest edge of the gutter helmet.
