Any experts on roofing who can tell me if this looks like a good quote?  I;m sure it does but are those good "coil fasteners", and does a city require a permit for this, I dont think so, and my biggest question here is, is there a potential problem with overlay versus total replacement?  House was built 1952, roof is about 20 years old, my intent is to sell either now or in 2 years. Currently a rental, I want to get it FHA ready.  Any FHA requirements on overlays vs total replacement?  Thank you for any information you might be able to share.  I researched FHA roof requirements, there is no mention of overlay vs replacement.

We try to leave your house and yard cleaner then when we started. Magnets are rolled through the yard, flowerbeds & driveway by the crew to pick up any roofing nails. If the job takes two days, we clean up most the first day. The second day will be the final clean up. We typically have one crew member cleaning up throughout the day to minimize the amount to clean at the end of the day.
