Sloping roof gutters.

To correct this yourself you ll need to measure from the peak to the downspout. If there s standing water it s not pitched properly. Get on a ladder after a rainstorm and look in the gutter. For spans longer than 40 feet it s wise to have a downspout on each end and start the high spot of the gutter in the center.

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. This means that your gutter should be a half inch lower in height at every 10 foot mark until you reach the downspout. For example if you have 30 feet of guttering the calculation is 1 4 x 3 0 75 i e.

This means the downspout end of the gutter should be set 3 4 of an inch lower than the other end. As a general rule gutter slope is set at 1 4 inch per 10 feet of guttering. Wrap the aluminum strip tight around the underside of the gutter. The standard slope for rain gutters is half of an inch for every 10 feet.

No matter your roofing system you ll need a system of roof gutters to help rain to drain away from your building. You want at least a quarter inch of slope for every 10 feet. Gutters need to be pitched toward the downspouts for the water to flow properly. One of the biggest challenges involved in gutter installation is establishing the proper slope of the guttering.
