My previous house had one under the toppest roof.
We left it there passing by a winter. In the next spring (no any insects there), My husband easily removed it. We bought a tele-pole (for cleaning window glass) from home deport. My husband stepped on the ladder and removed the nestle with the telepole.
If you don't want to take a safe risk, you can find someone from yellow book. The price is around $180 2 years ago.
