I have it in my mind that they want to go after me if im disturbing their nest. Maybe they arent the vicious critters im thinking of.

They can be very aggressive. Spray first, preferably before getting on the roof. The last thing you want is to be dancing around on top of the roof while being stung. A fall from the roof wouldn't be pretty.
