One of the gutter problems that I encounter most often is where the gutter has sagged on the NON spout end . It doesn’t take a lot of sag to make the gutter virtually useless. Think about it: If your gutter is let’s say 20 feet long with only one spout. The spout side of the gutter will give the gutter a bit more support in terms of stability..sorta like an extra crutch.. It makes sense that over the years the non spout end of the gutter will sag to a certain degree, especially if it sits packed with debris for months at a time. Remember that it doesn’t take many degrees before water and debris begin pooling on the wrong end. No es bueno porque nunca que agua fluye cuesta arribe.
