Rain gutters should slope between 1/3 inch and 3/4 inch per 10' towards the drain spout. Were you asking for the slope or are you asking how to achieve the slope? To achieve the slope: Lay out the pieces of gutter and fittings on the ground below where they are to be installed. Align them to correspond to the way they will fit when assembled under the eave of the roof. Use a long level to get the correct slope for each run of gutter. A slope of approximately 1in. for each 16 ft. of gutter is adequate to provide proper drainage. Good drainage is important. One easy way to accurately set the slope for proper drainage of gutter is to allow for a fall of 1-1/4 in. for each two 10 ft. lengths of guttering material. This can be calculated by marking the nailing position on the fascia of the house before attaching the gutter and then checking the fall with a level to be sure it is accurate. Locate the center of each span of gutter material. Mark this center location on the fascia of the house. Now take a chalk line and snap a line from the center position to the end of the run in each direction. Allow for 1 in. of fall each way. On an ordinary home installation, this fall of 1 in. in each direction from the center will provide adequate drainage. If the run is extremely long, allow 1 in. fall for each 16 ft. of gutter.
