Question
Greetings Carlo,  What is the easiest and least expensive way for me to kill a tree that towers over my garage, and appears to be lifting it by the roots?  I would appreciate any information.  Betty

Answer
That's a tough question...

Assuming that you kill the tree, you'll still have to have it removed.
That is going to cost you money.
How long has this tree been living there for?
If the roots are doing all of that, I would assume that the tree was already there before the garage was built.
It is part of the story of your place.
Why not to try to work around it, and save both, the garage and the tree?

Maybe, if you could send me pictures, I woud be able to help you.

Keep in touch.

Carlo
