For RoofReport I have used a Phantom 3 pro and my newer M210. I know of others that use their Mavic.
No thermal images for roof report needed, it's a measurement tool - everything you need to price replacing a roof. It's an awesome tool and I use it to gather info for roofing contractors- it saves them ALL KINDS OF TIME, not to mention not having to get up on the roof. All you need is the regular images from a 2D map, click the "generate" button and wait for your report.
