Our home faces down a hill. The flat roof drains at the back, on the uphill side. I’ve got flexible tubing directing drainage around the house to the street, but it’s unsightly and often in the way. I’m not willing to re-“grade” the roof so that it drains closer to the front of the house, but I had the idea that I could run PVC drainpipe from the existing downspout back through the space between the roof and the ceiling, out the side towards the front.
I realize this would be unorthodox, but would it be problematic/crazy/illegal/a code violation?
Thanks

Why don't you just bury the flexible corrugated pipe beneath the ground and run it to daylight down the hill?
That means some shovel and or trencher work, but you keep the water where it is suppose to be; outside the house structure.
Just be sure to put strainer caps on the exposed daylight end to keep unwanted quest from building nest in the drain pipe.

So you want to take the water that you've paid good money to keep out of the house and bring it back inside? Tough to keep leak free. Consider Dave's suggestion, except use rigid pipe underground, not flex.

This is a GREAT idea! Have you ever heard the soothing sound of water racing through plastic pipe, gurgling over your head while you're *trying* to sleep?
Oh.
On second thought, maybe it's NOT such a good idea after all. <G>
Guess you'll be digging a bit of a ditch to route your downspout underground a ways?

Unorthodox, to say the least.
As the previous posters mentioned, bury a 4" or 6" (depending on drainage volume) pipe underground and run it to the low end of grade away from the house.
On a side note...is this the only leader pipe draining the entire roof?
If there are others, find out where they drain....street? drywell?
Can you tap into that system?
It will require some research....make sure the current system can handle the additional load.

Unorthodox ways of doing things usually are problematic/crazy/illegal/a code violation. That's why they are unorthodox. I would bury the pipe as others said.
