Easy it is not! I do not fly mine any longer. The constant updates and risk make it not a pleasant activity any longer. A friend owns one of those aerial display companies - hundreds of drones under computer control. He gets less grief flying 100 drones or more than I get with one. I renewed my documentation earlier this year, but the constant changes in the rules make it tiresome. Insurance cover relies on correct documentation - yet completing it is always a best guess. The recent changes to bring in the lightweight drones that previously subject to some much scrutiny make it a continually evolving activity. Using them for business use is a risk. For some, perfectly workable - others find it a constant concern. The popular hobby drones oddly, would do what you want - but remember that to be compliant, what you want to do also needs two people. The popular first person view with the headset is what you would want the roof specialist to be looking at. However, the rules clearly make the use of real eye to drone contact required - at the same time?? In practice - one person would fly, the second person is the observer - that's two people to do it correctly. If, as loads of people do, you have a single pilot who uses the technology to fly the drone - and you crash into a neighbours property and do damage, your insurers might discover your transgression and duck out. The number of times I have looked from the drone in the sky, down to the controller and then been unable to find the damn thing again is not a rare thing.
