Sandytoes,
Thank you for your discretion on not turning your post into a "woe is me" pity party. We ALL faced nasty damage, had a tree limb come down a few feet where it did, I may not be able to answer this question.
For your situation, when you replace the roof, the main thing to think about are "hurricane straps". They are worth more their weight in gold. If you don't use them, expect the same thing to happen.
As for the trees and chainsaws, we are all paying for that. If a neighbor hasn't offered it for free, no one coming any distance will do it for free. After a Hurricane, nothing is free but neighbor helping neighbor.
Borrowing a chainsaw is bad because if you hurt yourself or mash up the chainsaw, the chainsaw owner faces criminal and/or financial charges.
In my 30+ years here it never even occurred to me not to pay someone for their work.
These are realities of a hurricane. You cannot escape them.
But, remember above all Hurricane Straps! Cheap and effective!
