I'd love to do this down here in Australia on my low pitch project coming up.

Hello. What exact liquid flashing product does Doug use? In Europe liquid flashing is pretty uncommon, but maybe would find something in my country. We basically use Siga tapes for all the joints ( but in my practise, in some exterior situations tapes failed and because of that I want to try liquid flashing)

lol ... when doug jumped up and down on the surface it didn't even move .. because he's only about 150lbs! Imagine Jordan jumping on that surface ... it would show on the richter scale.

Not the only one out there using Zip R on the roof. We just finished a 100 year old gambrel hip roof barn that the owners wanted insulated while maintaining the original interior. We staggered 2" foam sheets with 2" Zip R fastened with 6" head lock screws. Finished it out with 2"X4" purlins attached with 8" head lock screws followed by a standing seam metal roof.

Matt, if you haven't seen the independent testing on this system, I'd love to hear your perspective personally don't believe that the testing methodology would translate to real world applications, but I get more worried seeing it on rooftops.

how is he mitigating the agr's? That's what I want to know.

Great air barrier. Horrible moisture barrier

Thanks, the first time I heard of the zip R products, I thought the roof would be a great application. Would love to see an update on how this performed in a few years

This was way to brief. What's the whole build up here? How is he draining this? Edge detail?

Zip system specs say not to use on roofs with slope less than 2/12 .

3 inch nail schedule on edge with 6 inch schedule in field with 4 inch nails? Any particular type of nail? Adhesive to roof truss before placing panel? Thanks for showing.

Did the manufacture of the Zip system come out with updated installation instructions as I see some builders are covering fastener intrusion and some are not. Yes I did see the DuPont video but it wasn't produced by a independent tester so I am not sure what controls were used in their simulation.

I don't know if this would work where you have to consider snow load.

Do builders actually build anything? All they really do is hire people to build the project for them. They are not really builders more like worker and money managers. Nothing wrong with that, but they really need a new name like building quality control supervisors or something. The only builders are the guys wearing the tool bags with holes in their pants from moving material around and glue and paint on their shirts. It gets old hearing people ( especially homeowners) say that they are building a house when actually all they are doing going to the bank and filling out some paperwork and the hiring a guy (g.c.) who is hiring other guys (subs). And then they move in and tell everyone that they just built a house.

I would pay a lot for a complete builder’s manual containing your research and experience.

"off the reservation" not cool matt.

Insulate, insulate, insulate and air seal.

Is this assembly applied directly to roof joist framing?...or does it still require roof sheathing. Not 100% certain after watching the video
Mark Palmer Tuesday, February 6th, 2018
Have always thought this made incredible sense.
Maxima Tuesday, February 6th, 2018
Matt, several vids and internet articles on zip system leaking. Can you research and do a video?
EARL Tuesday, February 6th, 2018
Builders supporting builders. Love it. Great video as always

I hurried to click this one before it was gone lol
Matt Metcalf Tuesday, February 6th, 2018
Seems like you could get rid of the dens deck with this?
Nicholas Hartzler Tuesday, February 6th, 2018
Let me watch if before you remove this one!
