Rain Gutters Too Level

The pitch of gutter heading towards a downspout can also cause overflow if it s too steep.

Rain gutters too level.

Gutters should slope an inch or two for every 40 feet. Too much slope and the water can rush too quickly down the downspouts potentially causing erosion with even a moderate rainfall. Simple settling of the home over time can create a difference from the original slope of the installation. If the gutter is too level it will hold a lot of run off water and risk becoming too heavy for the supports to handle.

Get on a ladder after a rainstorm and look in the gutter. The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it. The gutter hangers are the way you mount the gutter system to your home so they need to be spaced properly. Multiply the number of feet by 1 16 inch to determine the total slope the gutter requires.

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. If there s standing water it s not pitched properly. Gutters need to slope towards the downspouts in order to function properly.

The most common gutter problem is blockage. If the gutter is tilting away from your house it could be causing an overflow particularly during heavy storms. Typically a section of five inch gutter that is one foot long can hold up to 1 2 gallons of water whereas a section of six inch gutter that is one foot long can hold up to two gallons of water. Avoid hanging the gutter hangers too far apart.

They must also remain free of clogs holes and sags. If the water doesn t drain to these downspouts it may end up pooling and causing damage somewhere else at your house. If you leave too much space between the hangers the rain gutters will actually sag causing the water to pool instead of flowing through. You want at least a quarter inch of slope for every 10 feet.

Your gutters aren t positioned correctly. 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. How to check a gutter s slope to check the slope of your gutters you ll need a ladder tall enough to safely get to your gutter and a one gallon bucket of water. The amount of collected water increases until it spills over the sides of the gutter.

For your gutters to work properly they should slope down 1 2 inch 1 3 cm toward the downspout for every 10 feet 3 0 m by code. Excessive wind water and debris can knock the gutters out of this alignment. Next place a ladder at the left side of the house and measure from the roof down to the gutter. That said gutters need to be completely level from front to back or water could spill over either edge.
