Underlayment

tomstruble

ive used titanium udl for some metal roofs ive done its strong,lightwieght and stays cool its got a really nice grippable surface and goes on quickly
There are some synthetics that are approved for staples Sharkskin is one [i think]

Way back in the day we used felt on the walls too, now Breathable house wraps because it is better.
I am led to believe the Synthetics Under layments breath too and as roofing goes its evolution and it is a easy up-sell as I think it is so much quicker to install that the cost difference is a good trade.
Part of my typical presentation, "No, we don't use felt anymore, evolution as we feel synthetics are a better product."

I won't use anything but Shinglemate, which is a fiberglass injected felt. The organic felts just don't hold up. Shinglemate is the same price as 30# and my customers like the free upgrade. I have used a product called palisade underlayment which I liked. http://www.sdp-products.com/HTML/feltfree.html

I won't use 15# felt on anything. It is an inferior product.

I use 30# felt because it holds up better for safety for the workers and because no one else is using it, so it is one more item to differentiate my company versus the other bidders trying to do things as cheaply as possible.

The last time I checked, Shingle Mate was about double the price, so I will check again to see if it is true that it costs the same as 30#. One better upgrade to differentiate myself with.

Ed,

Shinglemate is $41.50 per 4SQ roll here, and 30# felt is actually a bit more as it is $21.00 per roll for 2SQ. Go figure.

I don't like 30 # because it will buckle up if it absorbs humidity. It could lift up the shingles and lead to wind damge.

I am working on an estimate right now to replace a 6 year old roof that has frequent wind damge and it has 30# felt paper.

I have heard that so often about the 30# buckling, but we do not run into that problem.

I tarp up any exposed felt every single night though, so no rain or condensation ever has the chance to permeate the material, prior to installing the shingles.

I use the synthetics and have had no problems with it, I have seen it on the roof all winter at times and the building would be nearing finish and still have snow on it. No problems.

I have been using Perm-felt synthetic for awhile. Im paying about $14 per square. I love the 4' wide rolls by 10sq rolls . Saves a ton in labor when you only have a three man crew. I dont believe any felt is better than others once the roof has been shinlged but its code so I feel if im goin to use it, use the best. Also if I had to I would feel comfortable leaving it exposed over night.

try out the palisade or titanium udl. Both are great. I Especially like the titanium and both right around $100 for a 10sq. Roll
