And lastly, there’s an app to help you measure the roof. The main goal of this one is to make sure you measure the roof safely without the need to climb it and do the measures “the old way”. It’s some kind of pocket roller that lets you measure roofs with a built-in cam.

The mechanic is simple: you’ll need to use the cam to add points and to make measurements. Make sure to align the screen line with the line of your roof to measure the slope. Then, the app will calculate the pitch number and display it in the corner of the screen.

The app fully relies on your phone’s accelerometer, and holding the phone in your hands may affect the numbers. Thus, it’s more convenient to use some kind of a stand to make sure the image is still. Don’t forget to measure all sides, and the app will show the total number of squares required to make a roof and buy material.
