I built a 8-sided screened gazebo attached to my low deck. It sits on a yard with a fairly steep slope. When it rains, the water runs off the roof and is causing erosion and a small gully down the sloping lawn. I've thought about putting a border of small shrubs/flowers with mulch around the base to absorb the water or a border with gravel, but I'm concerned that the mulch or stones will just wash away as well.
I've considered a rain gutter to channel the water down the back side. But I can't seem to find gutter parts that have 22-degree corners and something "low profile" that doesn't cover the decorative ends of the rafters. Standard gutters look too big and seem like overkill for the need.
Any ideas?? Thanks!!
