15 # paper is about $5.8 per square including tax.How much is the 15# felt paper over there? We are very fond of Grace Tryflex Synthetic. About 15-16 dollars a square and shoot it down with button caps (I have a couple Bostich Guns for it) and sleep well at night- tomorrow you get to straight shingle.
We rip the big ones one day and shingle the next. !5 years ago we would do it all in a day...
I’ve never seen one of those guns for cap nails used. How dependable are they?How much is the 15# felt paper over there? We are very fond of Grace Tryflex Synthetic.

Our policy is to shingle whatever we tear off the same day. We don’t use tarps because they can blow away. We generally do the same although there are instances where we rip the whole roof and dry in what cannot be completed, in those instances we use synthetic underlayment .
However I’m wondering if we used synthetic underlayment if it would be safe to leave it over night. What do you think?
I was called to a custom home last november where the builder went bankrupt, 20% of the roof was completed and all the rest was exposed. We went in and dried in the roof with Triflex synthetic as to stop the OSB sheets from totally failing.
We had another nasty winter with snow and high winds and the synthetic is still holding up quite well.
I’ve got a couple cedar shake tear off jobs lined up that require plywood laid over the roof boards and I’m thinking about getting the plywood down before we get the rooftop delivery. In that case it might make sense to use a high grade underlayment so it could be left exposed overnight.
Maybe I could start selling synthetic underlayment as an upgrade and tell the customer that one benefit is it can be left exposed overnight and it won’t leak.I dont usually push the synthetics , however in the past few years I have been noticing an increase in customers requesting it be installed with their roof installations.
If I decide to include better paper with every job I would choose Roofers Select over 30 lb.My standard is 30# I don't use synthetics yet, but if I did I'd have to lower my installation rate because those 10 square rolls go down quicker.
Felt paper and tarps are not water tight and I won't leave them exposed over night. I have said it 1000 times: A dry in, isn't dry. We shingle what ever we tear off that day. Or the guys get to listen to me scream and yell the next day.
I'll do 30# or the Certainteed fiberglas felt for the same price.
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 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.
