Will it work on my roof?
Free is for thin coverings like slate. Pro is for every roof covering. What matters most is the distance from the sensor to the rafter nail — on some thicker free jobs, magnets can bridge the gap until Pro ships.
Always check the in-app guide for the covering in front of you.
