I have 5 inch "K-style" vinyl gutters on our house. To keep leaves and fir
needles out of the gutters, I have vinyl screens covering the top of the
gutters. They generally work well, except on the front and back of the
house where the roof valley's are.

The valley's channel a larger volume of water into one spot, and in some
of
the significant rain storms, there's so much flow it overflows the gutter
at the point going all over the yard and down the side of the house.

To make matters worse, the valley's also collect larger amounts of fir
needles which get washed down and pile up on top of the gutter screen.
This
basically builds a ramp for the water to come down the valley and straight
over the top of the gutter.

I could probably remove the gutter screen in that spot and collect more
water, but it would also allow debris to get in and clog up the gutters.

Any tips on what I can do to solve the problem? (Replacing the gutters is
not an option at this point).

Thanks,

Anthony

My father's house had the same issue. When it rained hard, the water
would flow down the 'valley' and totally overshoot the gutter. It was like
having a firehose squirting water on the porch. What we did was to take a
chunk of aluminum sheet (old snow shovel) and cut it into a rectangle about
12 inches by 6 inches. We then made a 3 inch cut (to the center) right at
the half way point of the 12 inch side. We folded it 90 degrees along the
12 inch axis, and then on the 'outside' of the "L" shape, we then created 3
inch flanges at 90 degrees as well. This gave us an "L" shaped piece of
metal, with 6 inch sides and a three inch flange to insert underneath the
shingles. We got some roofing tar and cemented the thing in place. When it
rained after than, the water would hit the upright three inch flange and be
redirected 90 degrees. This allowed the gutters to work properly and we had
no more problems.
