Every asphalt and fiberglass shingle manufacturer that I've run
across - maybe about half a dozen of the most common shingle
manufacturers - requires an underlayment or the warranty is voided.
Just the opposite of what you're saying. These include Tamko,
Certainteed, GAF, Elk, Owens Corning, IKO, Atlas, etc.



So how come each-and-every new home I see being built near my place
has the shingles nailed right over top of the bare plywood?



Wonder what a fire inspector or home insurance agent would comment about
this.


I'm not either but I know it's been a common practice, by builders, for at
least forty years.


Odd, I don't think I've _ever_ seen it done without the felt up in PA or
down here in TN.


Neither of my houses in NY (built in '68) or VT ('86) originally had felt
under the shingles. The NY house was a mass-built "starter house". The VT
house certainly wasn't. I have no idea what's under the shingles on this
house (AL - '07), but I think it does. At least the houses in the development
built after we moved in, do.
