we used to have an electric wire on the ledges at work. if it's right on
the peak of your roof, then something that interferes with their landing
would work. a coiled wire or something, perhaps. I've seen them sitting
right on top of the fake owl downtown. Maybe you have to move the owl
periodically for that to work....

What is the best way to keep pidgeons from landing on my roof?
