Hello Kevin,


You mean aluminum gutters, right?

To ensure that gutters drain properly, make certain they slope (1/2 inch for every 10 feet) toward a downspout. For gutter runs longer than 40 feet, it?s best to pitch the gutter down from the middle to a downspout at each end. Or you can slope the gutters down from each end toward a single downspout placed in the middle of the run. Determine what works best for the house?s orientation.

I don’t believe there is an “proper” slope.


I think everyone has their own ideas on what works and what does not work. Down here, I find a lot of 'flat' gutters which drain well, and we are talking 40', 50' and longer gutters. As long as it is not reverse sloped it drains well.

Not until you get leaves in it does a problem come up, and the solution is not sloping the gutter but keeping the leaves out.

Thus, I would say the "proper" slope for a gutter is 'as long as it is NOT reverse sloped'.
