Eave Trough (Gutter?) Pitch

[PJB12]

Hi All,

I removed some eaves troughs, which I think are also called "Gutters" for painting. The drip edge extensions were touching the tops of the troughs, making it all but impossible to reach in for cleaning maple leaves out. I wish to lower the troughs for access, so I puttied the old screw holes closed.

Checking on line for proper pitch for the trough revealed many answers. 1/16" per foot, 1/8", 1/4 and even 3/8" per foot.

What's the correct pitch per foot or meter?

Thanks For Helping!
Paul

As on flat roofs, if the gutters are dead flat, they will automatically drain, so first checking the level of the fascia will determine the pitch you'll need to overcome.

The minuscule amount of moisture, in a dead flat gutter, will simply evaporate.

Thanks for explaining, Snooyb.
