How to tell the pitch of my roof.

This is not difficult and is a. For a roof with the ridge above one wall the span is the same as the run. This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout. Roof pitch is simply the slopecreated by the rafter.

The pitch determines what type of roofing materials you can use safely how well rain runs off the roof and the estimated lifespan of your roofing system. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. The hip roof is another simply formed and easily built roof that efficiently sheds water. If you want to know how to find the pitch of a roof then start with a calculator.

The slope is the same as the pitch. No wonder it was the favorite roof type for the prairie school architects. This is the amount your roof inclines in a 1 foot span or the pitch of your roof. The 7 means that the roof rises 7 for every 12 it runs.

For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. Divide the slope by two to get the pitch. Place the end of your level the 0 inch point of your 12 marking against the roof surface. It is practical when there is not a pitch tool or angle tool available.

Contractors determine the roof pitch by measuring the vertical rise for every 12 inches of the roof. Here s an easy safe way to determine the pitch from inside your attic. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Roof pitch calculator is determined by the number of inches it rises vertically for every 12 inches it extends horizontally.

Roof pitch is often expressed as a ratio between rise and run in the form of x 12. Also referred to as roof slope or roof slant so what does the 7 12 in the example to the right mean. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. In this way it speaks to the horizontal plane tying the house to the earth.

This roof unlike the gable has a pitch on all sides so that it acts to cradle and hold down the house. Slopes range from low about 2 12 slope to severe slope about 12 12 slope. Hold the level straight and level bubble centered and then measure the vertical distance down from the your 12 mark on the level down to the roof. It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof.
