The roof is asphalt, but I've never found a decent standoff solution to keep the wire off the roof and soffits. I also assumed the unun would be much better off at ground level for better counterpoise options.What kind of house you got mister? Shingle roof or metal? If it was me, I'd get some wire the color of the roof or close to it and string it along in whatever shape you can get and put the balun under the soffits and run colored coax down the wall to the radio room.
