Gutters For High Pitch Roof

Roof pitch is very important for right roof gutter sizing.

Gutters for high pitch roof. There are two factors that go into determining gutter position on the eave the pitch of the gutter and the roof slope. The steeper a roof s pitch the more windblown rain it can collect. What material your roof is made of can also play a role. 6 inch 7 960 square feet.

5 inch 5 520 square feet. The gutter slope also called the pitch is the amount the gutter tilts down to let rainwater flow out of it. Multiply the drainage area by the roof pitch factor and rainfall intensity to find out the adjusted square footage. 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. Both types of roofs have their own benefits and challenges but when you have a steep roof you need to pay particular attention to managing the flow of rainwater and snow on your roof. Even the type of gutter can matter too. If gutters slope too severely they don t hold water and water could splash over the sides in heavy rain.

A metal roof for instance causes the water to rush down a lot faster than an asphalt roof. Ranch house with roof of 5 12 pitch 48 feet long with a small gable extending out over a porch at one end.

It s usually expressed as a number that looks like a fraction such as 1 12 for a very shallow roof or 18 12 for one that s very steep. You can measure pitch with a 2 foot level and a tape measure. A roof with a high pitch is steeper.

The angle of a roof on a house is referred to as the roof pitch. For a 1 12 roof for every 1 foot it rises vertically it runs 12 feet horizontally. Gutters play an important role in keeping your home structurally sound by directing water away from the foundation of the home. If gutters don t slope water gathers in them.
