Answer:
I destroy your home from the inside out.
I am constantly overlooked by everyone but everyone has me.
What has roots that nobody sees and is taller than trees. Up up up it goes and yet never grows?
I cannot be other than what I am, until the man who made me dies. Power and glory will fall to me, only when he last closes his eyes.
When you stop and look you can always see me. If you try to touch you cannot feel me. I cannot move but as you near me I will move away from you.
The answer I give is yes, but what I mean is no. What was the question?
