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.

How do you measure a roof of a building.

At this point you will also need to estimate or measure the overhang if you have one. Here we describe a basic measure for a ranch style home. 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. You ll need to figure out the vertical distance also known as the rise over a 12 horizontal segment also known as the run.

Measuring the area of your roof isn t the simplest process. The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials. This overhand measurement will need to be added to the measurement of the building. Once you have these measurements you will need to calculate the area of the roof and then you.

After this you will need to measure the length of the building from the ground. Record these values as roof rise over run with the vertical measurement listed first and the horizontal second. Measuring the amount of metal roofing you need is accomplished in various ways depending upon the style of your roof. 8 inches and you have an 8 in 12 pitch.

If this distance measures 4 inches you have a 4 in 12 pitch. Obviously you want to stay safe while still getting a close estimate. To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area. For example if your roof has valleys and dormers that will change the way you measure it.
