The standard slope for rain gutters is half of an inch for every 10 feet.

Use a measuring tape to determine the length of the gutter. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain. If gutters don t slope water gathers in them. The amount of collected water increases until it spills over the sides of the gutter.

Multiply the number of feet by 1 16 inch to determine the total slope the gutter requires. Rain gutters should be attached to the fascia and run the entire length of the roof ending with a downspout. The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it.
