 Let me ask John a question. John, is this area where the runoff is very high, meaning it's the velocity of the water coming off, kind of bypasses that gutter guard? Sounds like I think it was a gutter helmet that I had on my house a long time ago is what it sounds like. But is it at a valley area that you're seeing the problem? I don't know what you mean by a valley. A valley is where two pieces of your roof come together at an angle.
