Start your free trial. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches. It is often compared to slope but is not exactly the same. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Measuring for a metal roof begins with getting a ladder. To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. If the pitch of the roof is not that steep you won t have to worry too much about following.

The first of which is that you don t even have to go up on the roof. If your roof features any architectural elements like hip ridges valleys or dormers don t forget to find the length and width of these areas as well. First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials.

Make sure to document the number of chimneys. You will need to go up on top. The roof area for a hip end is the same as for a gable end the intersection is equivalent to a hip slightly conservative so there is usually no need to consider triangles when measuring a roof. To begin with you re going to go to the app on your mobile device or you will need to go to google earth on your laptop or desktop computer.

You should do this with someone that can hold one end of the tape measure so you can go to the other ends. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Measure any additional structures separately.
