kahljorn: I can tell you from my own field research that removing a ladder can be very effective.

I was about 14 and babysitting my brother and his friend, 5 years younger. They were playing in the yard and I went inside to answer the phone. Just as I made it to the phone, I heard thumping overhead. I grabbed the cordless and ran outside and the idiots were running laps on a 2 story roof in August.

I screamed at them to get down and they made fun of me. I thought I was going to have a stroke, watch them fall to their deaths or both. Finally I ran over and took away the ladder they'd propped up to climb to the garage roof and from there to the house.

Funny how fast they wanted down then.

In retrospect I should have called the cops or something and put them through hell.
