I have a pvc hoop shed that sits against the rear of my main resin storage shed. The rainwater flows down the taut tarp of the hoop shed & gets into the main shed floor. What's the best method to divert the water away?
Hoop Shed: (older pic that still shows how hoop shed is flush to resin shed on one side and deer fencing on the other)
i would wedge a length of plastic gutter on a slight slope between the 2 sheds , making a small gap and encouraging the water to run into the gutter and into a down pipe directing it away from both sheds. You may have to experiment a little for the height of this
Since, you already have one tarp, why not have 2? Put another tarp over the gap by screwing the new tarp to the shed's sides after running over the ridge. Then, run it down the right side of hoops where you can wire tie it without puncturing the existing tarp.
Of course, you could get a bigger tarp. Run it over the ridge & even all the way down the shed sides & then repeat what you did on the hoops. Use the original tarp somewhere else, as a floor &/or doors for the hoop structure. Or. string it up to those posts on your right to double your home's size...kidding, who would live under a tarp when they have a shed.
Which, leads me to. Get or make a bigger shed.
Moving either shed makes the most sense to me. Both don't look that hard to move. If you don't want to do that maybe try bending a piece of aluminum on a brake and flash it against the shed and cut it under the blue tarp to catch the water. I would move one or the other shed.
