I will be insulating a crawlspace under a room in my house with tiger foam this summer, do I need to coat it to make it fire safe? Or cover it for a fire stop?
The easiest thing I would use is one on the paint on coverings, but if it is not needed I won’t use it.

Does drilling new screws into the roof rafters compromise the strength of the roof?

check the ESR
I'd say you have to cover that with a thermal barrier or at the very least an ignition barrier.
Call the company and ask for an ESR report. That explains exactly how the product is to be safely and legally used in buildings. I did a quick search and didn't find it pop up but maybe they have one, it cost $$$ so not everyone pays up or goes thru the effort.
Without an ESP allowing otherwise you must follow building code in your area, plastic building insulation in the word to look up.
