I have one up here that rocks.

That doesn't help you.
One word of caution. I got 2 estimates that were VASTLY different. (My estimates include fixing the mortor in my brick chimney. You could see between the bricks. Yikes. Also included is the detached garage.)
Estimate #1 = $14K
* Remove old roofing. Replace with the 30 yr stuff.
* Remove shingles from detached garage. Replace with rubber roofing. (pitch of roof too low for shingles)
* Tear down and rebuild chimney from roof up (the rest of the chimney is in the middle of the house and OK)
Estimate #2 = $8K
* Roof over old shingles with the 30 yr stuff.
* Remove shingles from detached garage. Replace with rubber roofing.
* Repoint chimney. (What's to repoint? There was no mortor there to repoint to.)
I went with the higher price for a job I considered to be done *right* vs a job simply *done*.
Just be sure you get detailed estimates or you might be comparing apples to oranges, and a seller is going to want to see only the lower cost, not the lower quality job.
