Rainwash off roof corner raping flowerbed underneath

[Fried Chicken]

In lieu of text I'll post pictures:







Exists there some sort of diverter or something to distribute the water as it comes rushing down from the roof?

I wouldn't even know what to look for "roof corner water diverter"? Posting now as I start researching options.

Gutter

Other than a gutter. Even a gutter here probably wouldn't handle the niagara river that flows when it rains

A gutter would alleviate most of the erosion . Only other thing would be to put pavers down where the majority of the water hits the ground . And getting the water away from the foundation is always a good idea

I have a roof with large valleys and gutter.
Heavy rains run over the gutter and dig holes in the ground.
I've since filled the holes with decorative stone and all is well.

Anyone have any experience with something like a Rain Diverter?

Thought of doing this but the location is inconvenient and the intensity means it's not in one spot.

You probably should install gutter and then something like this. As @SS396driver said you should try and get water away from the foundation.

Hey Steve, what is that thing called? Can it be installed without a gutter?

Water around the foundation isn't an issue here, and not this spot as it gets the brunt of the sun.

You can buy flashing and cut yourself, install under shingles without gutter.

I have these on my valleys. They work well. That being said, they are worthless without a gutter. allowing water to run freely off of a roof and down the foundation opens the door for much larger problems.

From what I see in your photos, I'd have to disagree. I can see mold/mildew on the brick 4' up the side of your house.
What is this? A sprinkler head, or maybe a ant trap?

I have a similar situation on my old farmhouse. Literally all the rain that falls on half the house runs down a single valley. I've been here 30 years and have yet to find a solution. I tried a gutter, but when there's a gullywasher, it just runs over. I have plastic tubing over the end of the downspout that runs away from the house... but none of that really helps at all. Now the wood facia behind the gutters on the house are rotted.

How about, since it is a garden area, you put/build a nice rainwater catchment in that corner?
I was going to make a ferrocement container years ago, but never got around to it. You can get creative and make something really nice-looking for the garden

I have the book and highly recommend it.

Or, maybe a nice little fish/frog pond?

It sounds like you just need larger gutters? Standard size I think is 4" but I have seen them up to 8"
Also as mentioned above a rain diverter to distribute the water away from the corner of the gutter where they can better catch it.

What I should have done is never put up the gutters (never had any before since 1900 when it was built) and built the ferrocement container.

We had similar issues at work with one of our out buildings. The installed 8" K gutter and larger down spout. Looks a bit oit of place, but no amount of rain has come over the gutter since it was put up.
