Let me qualify what I'm about to say by stating that I have not been in a tree for over 2 years using a rope, I'm a landscaper by trade and training with some aboriculture training thrown in. I am most DEFINATELY not an expert on climbing trees and/or removing those that need climbing to accomplish that goal.
When I'm in a tree, normally I'm not worried too much, I know my system, I know I've checked it over and I trust my equipment, because that is what it is made for.
However I have had the daylights scared out of my (and my professor was worried too, I might add) when in my arboriculture class my feet were knocked off of the trunk of the sycamore tree I was in. I was only about 10 off of the ground and was cutting off a limb (the tree was to be removed). The limb was tied at the tip and at the trunk, and when I cut the limb, it swung back and knocked my feet off of the tree. Didn't hurt, but it sure made me think twice about any future rigging I did. This was a controlled environment, and a "hands-on" instructional period.
If something can happen in this type of environment, it CAN and probably *WILL* happen to someone untrained.
I have been in numerous trees since that fine fall day, and I personally don't think I have enough experience and/or knowledge to attempt a removal of this type. Too much at risk between the house and the power line, not to mention personal injury. It's not worth it.
My advice, if you are not willing to call someone with the training, experience, and equipment, would be to take anything valuable out of the the front rooms of the home, move the bedrooms to the back of the house and check to make sure your homeowner's insurance policy (do you even have insurance?) is up-to-date and covers storm damage. And when the wind is blowing real hard, find a friends house to stay at.
As an aside, and completely off of the removal subject, anyone else think that if the tree is truly dead that the brick wall around it might have something to do with it?
