so ive been doing residential and light commercial roofing for about 12 years and one of my guys suggested we start using a drone for inspections instead of suiting up and climbing every time. i got a mini 3 pro a while back for personal stuff but never really thought about using it professionally until now.

the thing is most of our roofs are pretty straightforward gable or hip stuff, maybe 6/12 to 9/12 pitch, so climbing isnt usually a big deal. but we do get the occasional commercial flat roof or steep metal roof where a drone would genuinely save time and reduce risk. my question is whether the image quality is actually good enough to spot things like lifted flashing, cracked caulk around penetrations, granule loss on asphalt shingles ? the kind of stuff you need to see up close.

also not sure if i need to bother getting part 107 for this since im technically using it for my own business inspections and not selling inspection services specifically. anyone been down this road already

part 107 question ? yes you need it if youre using it commercially even for your own business, doesnt matter if youre not selling it as a standalone service. the FAA doesnt care about that distinction. got caught on this a few years back and its not worth the headache.

on the image quality thing, the mini 3 pro is honestly fine for general condition assessments but if you really need to pick out hairline cracks in caulk or early stage granule loss you're going to want something with a better zoom. a lot of guys doing this professionally run something like the Mavic 3 Enterprise or the Autel EVO II Pro just for the variable aperture and the optical zoom range. the mini 3 will get you maybe 4x digital zoom which gets soft pretty fast. for the obvious stuff ? missing shingles, standing water on flat roofs, damaged flashing that's visibly lifted ? it works totally fine though.

we do commercial roof surveys with a P4P v2 and honestly it replaced probably 60% of our ladder time on flat roofs. steep residential is still a climb for us because the angles are awkward to get close enough without risking the drone, especially near ridgelines and HVAC units. but for a big warehouse roof or a school building its night and day for efficiency. we can do a full condition report with photos and a rough thermal overlay if we attach the right sensor, way faster than walking the whole thing.
