Here’s one for you roofers and or gutter installers out there.
What do you do to control water runoff when two large roof planes meet in a valley? A large volume of water collects in this valley during heavy storms, and it overshoots the 4″ gutters on the inside corner.
I don’t think even 6″ gutters would catch the valley runoff, but I’m open to arguement.
The code requires installing an approved material to slow the spread of fire between floors and adjacent vertical and horizontal cavities — here are the allowed materials and required locations.

Blue Thumb,
I bend up a little piece of flashing that slides under the valley and turns the water so it runs into the gutter.

So it's like a diverter at the end of the valley? Do you have the dimension and how it is installed? A pic would be nice.
No pics. About 3" high with 5" sides. Depends on the sizes of valley and gutter. Sometimes screw them to the top of the gutter itself. Cut a pretty on top.

You mean you sometimes screw it on the outside lip of the gutter to act as a stop?
I have that same problem with my valley in very heavy rain only which doesn't happen that often. Below is a slab patio so I just let the run off pour onto the slab.

I bend a piece of aluminum flashing into an "L" shape. This piece sits on top of the outside lip of a "K" style gutter. You can screw it on top with self tappers, or pop rivet it on top. Attaching it in this manner hides the fasteners from view.

Take a look at this............from a post above.

If you cut the flashing with a bit of "flair" and prior to putting it up on the gutter, it might appear to resemble "elephant ears".
I dont have any pictures handy, but I make two 45 degree miters rather than one 90 degree miter at inside corners where water jumping the gutter is a potential problem. This creates a triangle of gutter at the bottom of the valley and it looks kind of cool also. I've done it with both ogee and half round gutter.

Valley Runoff
My new house has a standing seam roof. How can I divert the water flowing down the valley between two roof lines so that it ends up in the gutter rather than overshooting it?
What the heck are elephant ears'?
Thanks,
Richard

Essentially just a L shaped piece of metal. I would attach it to the outside of the gutter as shown in the above link. Attaching it on the roof seems like an opportinuty for ice daming.
