I'm hesitant to comment behind some of these posts, especially the last by LouNY and that of Airbiscuit directly above. However, if I'm not mistaken that's aluminum roofing (?) which will make it even more difficult to get off without damaging. You might consider using that for siding, where a few holes won't matter as much; then invest in some new steel roofing material.
My brother just moved back to Maine after living in Phoenix for 20+ years, and it's taking him some time to get accustomed to people who are willing to help just because they're neighbors. I can't imagine being in your situation without somebody offering to help. Heck, every store that I go into has a jar out asking for help for somebody who needs it, whether it's a kid with cancer, somebody with an unexpected illness, or a family who's provider died unexpectedly.
