What is the proper gutter slope toward the downspout?

The proper gutter slope toward the downspout is crucial for ensuring effective water drainage from the roof through the gutters and down to the ground or drainage system. A slope of 1/16-inch per foot is the accepted standard because it allows for sufficient drainage without creating a situation where water flows too quickly, which can lead to splashing and insufficient water capture. This slight slope helps ensure that all water flows toward the downspout without pooling in any sections of the gutter.

Having a minimal yet effective slope is important for preventing issues such as clogs or overflow. If the slope is too steep, it can cause water to rush through the gutters too quickly, while a slope that's too minimal can lead to stagnant water, encouraging growth of debris and potential leaks or damage to the gutter system. Therefore, a slope of 1/16-inch per foot strikes the right balance for maintaining optimal gutter performance.
