Roof valley rain runoff solutions
Posted on 12/10/19 at 12:47 pm
Posted on 12/10/19 at 12:47 pm
Right now I only have gutters on the back and front side of the house but not to side. The rain from the roof valley in the corner floods the soil and has caused the water to run under my house(on beam).
This has added to the moisture problem for my floors. I'm trying to fix the rain from going under the house to prevent further problems.
What kind of DIY solutions do I have apart from installing gutter?
Is something like this to make it flood away from flower bed even a good idea?
I have so many issues to fix with my house
:lol:

Gutters with a down spout straight into a french drain will get it out of there best. You could install a rain collection bucket for now

Yeah that little piece of metal won't do anything. If you don't want to install gutters, then a rain barrel + hose is your best bet. Or regrade the ground by digging a swale away from that corner.

Pics of the ground and runoff area would help

It is in the corner of the house in the backyard. The rain barrel is a great idea for now. Noone could see it and doesnn't make it ugly looking or anything. Thank you

I will take pics when I get home

Post pic of the bed in question. You can probably do some hardscaping in that area that would allow the water to flow freely out into the yard. We do it all the time in landscape jobs where the homeowner does not want to add gutters. It’s an easy DIY and pretty inexpensive.

You need to contour the area so that the water drains away from the house. Do you have a gravel bed laid from the foundation out to about 2-3' from the house? That's a good place to start, then if needed, you can run a french drain from the corner beneath any landscaping beds that may be higher than the gravel beds.
Also, you can put up a partial gutter to divert the water away from that corner, if there is a nearby spot that has better contour/drainage away from the house.

The water from valley falls onto the bed and flows under the house like a creek

"The water from valley falls onto the bed and flows under the house like a creek"
Does it stay puddled under your house, or flow directly downhill?

It flows in different directions depending on the contour and stays as puddle for a day. The house is a cottage style that is 60 year old and the gradient is all messed up.
I'm trying to cut the water at the source and prevent the water from getting into the bed. Forgot to show that there is a concrete path around the flower bed. So there is no way to dig a trench without cutting into concrete.
I think i like the rain barrel with hose as an easy low maintainence option so far.

The rain barrel will overflow and the problem will still exist.
You need to put gutters on the house (maybe just a section? If the other parts drain okay) and run a downspout out away from the foundation area.

I'm getting estimate for the gutters for that section
Posted on 12/10/19 at 10:24 pm to glorymanutdtiger
I wouldn't think of much of anything else other than gutters in that type corner.
Just to give you an idea of how much water can come down a downspout of a gutter, consider this fact of mine:
I have one of those 55 gallon rain collectors on a downspout. This downspout handles about 1/4 of my roof (gabled roof) and the collector will go from empty to full with just about a quarter inch of rain.

Yeah it's a lot of water. 1 inch of rain on a 500 sqft section of roof equals ~42 cuft of water volume, or >300 gallons.

These calculations are correct - rain barrel collection will not be the solution to your problem b/c of the sheer volume of water flowing off the roof. Gutters, as others have mentioned that will allow you to divert water away from the house foundation, combined with additional diversion of the “guttered” water away from from the house, if needed, via French drain, graded swale, under ground gravity drains, even a sump pump — is going to be solution to your problem.
I use gutters, gravity under-ground drains and a couple sump pumps to keep water away from my house foundation (slab on grade). Perhaps outside of the gutters, much of this can be fairly “easy” DYI projects if you are so inclined.
It’s good that you know and understand you have an issue that you need to resolve as it relates to moisture under your home and the potential damage it can do, long term, to your wooden floors.

Gutters are pretty cheap honestly

Yep. Got an estimate and it was around 800$ for that section and more. it was cheaper to do more.
what about rain barrel with sump pump

A 55 gallon rain barrel will fill up in 30 seconds on a steady rain.

Why don’t you put in drainage and convey it under the house to a drain somewhere else?
