The pitch of gutter heading towards a downspout can also cause overflow if it s too steep. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain. If the gutter is tilting away from your house it could be causing an overflow particularly during heavy storms. For gutter runs longer than 40 feet it s best to pitch the gutter down from the middle to a downspout at each end.

Or you can slope the gutters down from each end toward a single downspout placed in the middle of the run. For a 1 12 roof for every 1 foot it rises vertically it runs 12 feet horizontally. And the roof slope. 5 inch 5 520 square feet.

Multiply the drainage area by the roof pitch factor and rainfall intensity to find out the adjusted square footage. To ensure that gutters drain properly make certain they slope inch for every 10 feet toward a downspout. If a roof s various drainage areas call for different size gutters go for the biggest one k style. Gutters keep your home structurally sound as well as ensure that water does not reach the foundation of your home.

Then use the chart below to see what size gutter you need. If gutters don t slope water gathers in them. Gutter should be pitched 1 16 or greater per foot for proper drainage. Hold one end of the level against the roof level it and then measure the distance between the roof and the underside of the level at its midpoint which gives you a 12 inch run.

Gutters should be placed below the extended roof line so that snow and ice can slide clear. Gutter can be run level for appearance but addition downspout will be necessary see section on proper gutter and downspout sizing. The angle of a roof on a house is referred to as the roof pitch. 2 your gutters aren t positioned correctly.

However if they are not functioning properly they can cause rainwater to fall to the downspouts. The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it.
