   It's not only o.k., but a better choice- especially if some will be left uncovered for overnite or longer

   Isnt it amazing how some "contractors" will risk getting calls at midnight for a leaky roof instead of spending the extra $100 dollars or so for better underlayment?

   Hey, some guys on here use #0 for underlayment.

   Tell me that ain't a sight to see.Where is this division of labor to end? and what object does it finally serve? No doubt another may also think for me; but it is not therefore desirable that he should do so to the exclusion of my thinking for myself.

   Back in '89 I was framing in Coopersburg PA. We never felted any of our decking. The boss said that was a roofers job. Here it is the framers job.

   After we built about ten the ice hit and covered our decking and still no roofers or felt. Thyen starting in December when they finally came they just broke the ice off and laid shingles on the wet, frozen decking.

   But it is no better here, minus the ice of course. Most GC's try to pocket that extra money they save.

   I've seen some framers slide off a house that was steep when teh #15 felt ripped.

   For one thing, it's not 15 or 30#;  it's #(number) 15 or 30 unless you spec out the true 15 or 30 pound felt which is the commercial version and not readily available.

   #15 felt is pretty flimsy although I still see it used, usually by the low ballers.

   Tamko will warranty the #30.   You were probably talking to a minimum wage newbie.
