This can make it even safer to do your measuring and it also removes a level of guessing to your calculation. Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark.

Note the vertical distance on the tape measure and write this value down. 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. The google maps area calculator is not 100 accurate.

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. 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. Measure the vertical distance from roof to level. Hold the 0 mark of the tape measure against the roof.

To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area. It is often compared to slope but is not exactly the same. The first of which is that you don t even have to go up on the roof. First measure 12 inches from one end of the level and make a.
