Do I Have To Put Gutter On Level Or Slope. Pull the gutter down about 3 quarters of an inch lower than it originally was. Rain gutters have to slope down to the downspout for proper drainage. If the pitch is too gentle water will just fill up in the gutters until it overflows and a too sharp pitch isn t aesthetically pleasing.
This brings up another important rule to keep in mind. All guttering must slope toward the nearest downspout.
If they are bent out of shape carefully apply pressure to bend them back.
Most contractors tend to set the slop at one quarter inch per ten feet of guttering. Or you can slope the gutters down from each end toward a single downspout placed in the middle of the run. If gutters don t slope water gathers in them. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain.
