Correct Slope Of Gutters

Proper rain gutter slope.

Correct slope of gutters.

For gutter runs longer than 40 feet it s best to pitch the gutter down from the middle to a downspout at each end. Roof gutters need to be pitched toward the downpipes for the water to flow properly. The right rain gutter slope is subtle enough that you won t notice it from the street but also steep enough so that it easily sheds water towards your downspout. A correct gutter slope prevents standing water caused by rainfall from accumulating on your roof gutters.

The amount of collected water increases until it spills over the sides of the gutter. For water to drain towards your downspouts your rain gutters need to harness the power of gravity so that excess water flows downhill. To correct this yourself you ll need to measure from the peak to the downspout. Roofing and guttering experts recommend that gutters have at least a quarter inch of slope per 10 feet to avoid standing water on your roof gutters.

One of the biggest challenges involved in gutter installation is establishing the proper slope of the guttering. You want at least a quarter inch of slope for every 10 feet. The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it. If gutters don t slope water gathers in them.

From a distance gutters appear to parallel the roofline. But in reality they must be sloped ever so slightly so the runoff water can flow downhill to the downspouts. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain. Gutters need to be pitched toward the downspouts for the water to flow properly.

If there s standing water it s not pitched properly.
