How Do You Measure A Roof Of A Building

You ll need to figure out the vertical distance also known as the rise over a 12 horizontal segment also known as the run.

How do you measure a roof of a building.

The next step is to measure the pitch also referred to as the roof slope of the roof deck. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. One way to get an estimate is to take the square footage or meterage of the building and multiply it by the slope factor pitch of your roof. Measuring the area of your roof isn t the simplest process.

Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof. After this you will need to measure the length of the building from the ground. At this point you will also need to estimate or measure the overhang if you have one. 8 inches and you have an 8 in 12 pitch.

This overhand measurement will need to be added to the measurement of the building. Measuring the amount of metal roofing you need is accomplished in various ways depending upon the style of your roof. Here we describe a basic measure for a ranch style home. Obviously you want to stay safe while still getting a close estimate.

Record these values as roof rise over run with the vertical measurement listed first and the horizontal second. The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials. Once you have these measurements you will need to calculate the area of the roof and then you. If this distance measures 4 inches you have a 4 in 12 pitch.
