In order to know how crazy you are before you go walking around on a roof, you must first put a pitch gauge on the slope. This drill is mandatory for most, if not all carriers. Some adjusters like the old school Johnson tool, while others prefer newer, digital versions.

& Tool 750 Pitch and slope Locator
Adjuster X Recommended
This gauge is durable, doesn’t need batteries and is always accurate. Your grandpa probably used one of these 50 years ago when he was an adjuster and he was probably a badass, just saying.
Digital Pitch Gauge
The digital pitch gauge offers precise digital pitch readings and also looks cool in roof edge photos.
