Hi, Wayne! Welcome to our forum!
I'm an adjuster, too (inside). As a pro, your needs are different from those of hobbyists. You need to develop a high degree of piloting skill, such that your stick movements become innate--like the subtle balance adjustments you "automatically" make while riding a bike. This takes practice, practice, practice. You need to not only read, but to internalize your manual. Don't be embarrassed to use prop guards. A prop strike usually means a crash, which usually means a damaged drone. Time is money. A crash will cost you both time and money, and maybe a client as well. It may be wise to have a second drone for immediate back up.
Roof inspections can be tricky. Often they have tree branches and/or power lines which can be in your way. Wind damage and large hail strikes may be easy to spot, but small hail strikes can be difficult to document using only a drone.
Also, beware of liability claims--a neighbor of the insured can claim that you peeked in her window, and file suit against you. You'd probably win out, but defense in court can be costly.
Good luck in your new endeavor. Glad to have you with us.
