I often use the PVC vent pipes already sticking out of my roof to mount light antennas on.
Like this person did with their homebrew TV antenna.

that must be in very low wind area
Ok i remember now, it was in the handbook, but it was talking about how you can load up your rain gutter on your house and use it as a loop antenna on 20m/40m. But to be safe, power levels need to be kept at 100w or less do to the chances of rf heating and starting a fire. I would think the same applies to an antenna touching the house as wellI read somewhere, i think the arrl handbook that high rf power can be a fire hazard if the antenna is in contact with a wood frame structure. ????, you Might wanna look into that
At what wattage would a guy need to start worrying? Thay is the question.If you're only running 100 watts, I wouldn't worry about it.
1kw thru insulated wire no problem. The issue is why have the antenna just draped over the roof when there are better options? Also i bet at even 100w your gonna have serious antenna tuning issues, reflect etc. Also your radiation pattern and angle are gonna be terrible. I urge you to explore the many different alternativesAt what wattage would a guy need to start worrying? Thay is the question.
