Blue Frog. Nice idea, just not sure how you'd make sure you're always filming the gutter and not the edge or the roof. Maybe I'll give it a try. (BTW what happens if someone phones you whilst your phone is 18 ft in the air

)
Mirror, yes possibly, ladders, yes, although doesn't show the custy. I have been cold canvassing with my pole and camera and have now lost a couple of warm prospects because the image is so bad. This is a gimmick that will work brilliantly with a better camera.
BFG sounds great. Have you tried it? Is it a good clear image? Is there any chance you could email me a pic? If it will do the job I need then yes, instantly, I will buy it.
