If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain.

My gutter guy runs level all the way until 2 4 feet from the end then gives it 1 8 1 4 downward into the downspout. Multiply the drainage area by the roof pitch factor and rainfall intensity to find out the adjusted square footage. Since gutters settle as screws and brackets loosen it s a good idea to periodically check the pitch of the gutters and adjust them if needed. The rule of thumb for this slope is a vertical 1 2 inch for.

If gutters don t slope water gathers in them. Steeper pitches require less clearance. The amount of collected water increases until it spills over the sides of the gutter. This is essential for proper roof gutter sizing.
