Underlayment

user182

What synthetic underlayments do you recommend?

Have you used Rooftop Guard? I used it on one job, I liked it.

Deck Armour is priced too high, but I like the fact that it can breath. Rooftop Guard is a vapor barrier.

Our policy is to shingle whatever we tear off the same day. We don’t use tarps because they can blow away.

However I’m wondering if we used synthetic underlayment if it would be safe to leave it over night. What do you think?

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.

What type of underlayment do you include as a standard feature with every proposal that you make?

My standard is 15 lb felt paper.

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...

15 # paper is about $5.8 per square including tax.

I’ve never seen one of those guns for cap nails used. How dependable are they?

ronbryanroofing

Very. Caps are pre bound 100 count I believe, staples like a gun. Its slide, shoot slide shoot not bang bang like a roofing gun. It will but the staples sometimes bend over. 700-800 square with them and not one jamb. I personally have never slap stapled myself to the deck but I have seen others and this with the slide and shoot smoothes the Tryflex then secures. I generally dry in top down and I can run out a new roll of Tryflex alone- flat and straight. Pretty little spots "shoot here" down the middle and I don't have to worry it will blow off like felt. May look a little bumpy but smoothes out flat.
I'd like to think I am a gadget guy and this is a good one.

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 .

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.

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.

If I decide to include better paper with every job I would choose Roofers Select over 30 lb.

Have you found that customers appreciate the better quality paper?

Or does it just make your price that much more than the other guys and it doesn’t help close any more sales?
