Never Clean Your Gutters AgainGutter Guard Installation in Eldora, IA

Valleys deliver more water than anywhere else

Where two roof planes meet, everything landing on both of them funnels into one channel and arrives at the gutter as a jet. The flow at the bottom of a valley can be several times what the rest of the run sees, and it is concentrated into a couple of feet of gutter. That is a hard place for a guard. A mesh that keeps up easily along a straight run can be overrun at a valley outlet simply because more water is arriving than the openings can pass. It is also where debris concentrates, since the same funnelling that gathers water gathers leaves. Handling it well usually means a diverter or splash guard at the valley to break up the flow and spread it along the gutter instead of dumping it in one spot, and sometimes a different guard treatment for that short section. What does not work is ignoring the valley and assuming a product rated for a whole house applies evenly to every foot of it.
