Does anyone have any guttering options that they know of for the plastic corrugated roofing material? I'd like to be able to direct the runoff rather than having it just drip onto the ground below, but the end of the material is about 8" away from the back of the last purlin. Anybody have any tips? Here's a pic of my setup that kind of shows the situation. You can't really see it, but to the left of the tree, above the top of the fence is the end of the roofing. I guess I'm mainly wondering whether or not there is a gutter that's made specifically for this stuff. Thanks!
