I’ve only used felt paper as a roofing underlayment (except vallies). I’ve been seeing material like palisades underlayment. I’m writing a bit for a roof job in the next couple of days and am looking into what is available. I’ed like some feedback from those who have looked into it and/or have used these underlayment beside felt. thanx

Insurance industry research shows that stout roofs, strong windows, and metal connectors can help protect houses from high wind, hail, and hurricanes.

The new ones are well worth using and no roof should be without an underlayment.

One thing I learned at the last JLC Live event I went to that I'm not sure we've talked to death YET here:
Q: Some manufacturers specify Button cap nails for their synthetic underlayment... but button cap staplers - OK or Not OK?
A: From Titanium UDL, the one who says "No Staples" every 9" across their product - Button Cap staples are not OK. The reason they give is that staples have square edges, where nails have round edges. The square edges may cut the plastic when stressed.Rebuilding my home in Cypress, CA

i guess I don't understand your question.
It tis trye that for any underlayment from tarpaper on up that the square edges of the metal caps are more likely to tear it out in high wind. The original fasteners were tin tabs with a roof nail thru them, then we started stapleing them, but a tin tab is flexible so it was rare for them to cut the paper.Then Simplex came out with a ring nail in a square cap that was hell on your fingers, but held pretty good. Then the caps became round, which was better, and they had a compression shape to them.Then finally the ring nails went into plastic caps, and recently there are guns that will shjoot them. Whew! We've finally arrived, with a way to keep it on the roof for up to six months and do it easily!

I've not heard of that particular product in the other reviews and discussions. Do you have a link to that product? There may be someone here who has first hand experience with it.

I just had mine done with Titanium and it did a very good job. (given that it rained a month here with just the underlayment on). Pretty light and easy to install. I seem to remember it being a LITTLE more than the felt paper, but less than the ice/water shield. (although you do still need that for certain spots on the roof).
