Gutter Pitched Roof

There are two factors that go into determining gutter position on the eave the pitch of the gutter and the roof slope.

Gutter pitched roof.

Get on a ladder after a rainstorm and look in the gutter. 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. By using a stainless steel micromesh filter that never rusts and stops everything except rain water from entering your gutters gutterglove makes sure that clogs and blockages can t form ensuring your home is protected from rain and water damage. A light rain or drizzle for example remain remain on a flat roof for a short period of time.

You can measure pitch with a 2 foot level and a tape measure. You want at least a quarter inch of slope for every 10 feet. The steeper a roof s pitch the more windblown rain it can collect. Generally a contractor that drains a gutter onto a lower roof will say that it is an industry standard whereas a contractor that rants against it will say that it s not best building practice.

Roof pitch is very important for right roof gutter sizing. So it s a matter of what the home inspector or contractor considers acceptable. If there s standing water it s not pitched properly. Gutters need to be pitched toward the downspouts for the water to flow properly.

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. Pitched roofs have peaks and valleys that direct water downward in very specific directions. Gutter can be run level for appearance but addition downspout will be necessary see section on proper gutter and downspout sizing.

Gutter should be pitched 1 16 or greater per foot for proper drainage. The amount of collected water increases until it spills over the sides of the gutter. There is no building code citation that forbids a gutter from draining onto a lower roof. To correct this yourself you ll need to measure from the peak to the downspout.

Flat roofs operate with the same basic principle but of course their lower angles mean that gravity isn t quite as effective in shedding water rapidly. Gutters should be placed below the extended roof line so that snow and ice can slide clear. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain. It depends on who you ask this question.

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. However for gutters to function correctly they require a slight slope called a pitch which causes rainwater to flow to the downspouts. The steeper a roof s pitch the more windblown rain it can collect.
