I think I had Owens Corning used on the barn re-roof. They used some sort of underlayment that was not felt. I had used felt when I did the roof back when I built the barn. I would have to look for the receipt but it was those fancier shadow shingles with a higher wind rating and longer warranty. I also asked for starter shingles which they do not normally use, they just like hacking off regular shingles. Kind of funny how contractors do not like to follow product line start to finish. That said I did not use starter shingles when I did the roof myself but I was using 20 year shingles.

In lots of areas the trend is to use a self adhesive 'rubberized' underlay, the best I believe, being Grace Iceshield, but other brands are out there.
Those underlays are self healing (pull out a nail and the hole closes up) sort of a soft non cured rubber.
For my 2 cents, those underlays far outperform any felt paper you can find.
I did my roof this summer, covered the whole thing with the underlay and then had all the time in the world to shingle over the underlay.
As the factory tech rep remarked; The underlay is the sealant and the shingle is for wear resistance.
The underlays, by nature (soft sticky) can not stand up to weathering so a regular shingle needs to protect the underlay.
Regular shingles have 2 basic binders. Paper mulch, tar impregnated being the most common and some fiberglass type binders.
The paper mulch type being old newsprint stands to reason that as the tars dry out the shingle shrinks, curls and sheds the granules that act as the protection.
I expect my roof to now outlast me!
(at my age that won't be hard! LOL)

I'm a building material distributor and we got out of the Tamko shingle line. I guess it was because they couldn't supply the volume we needed and they didn't stand behind their so called warantee.
We move approx. 50,000 sq of Certainteed shingles a year and have for many years now. They are real good on their warantee claims if needed and now the Max Def pro is selling BIG! Lifetime shingle . . . .Good Luck, John
