Membrane and shingles

“

- [Instructor] Chapter 6-03, we've got the membrane and the shingles to put on though. This is the waterproof element of the deck. Now I could've easily added this to the other one but I thought it would be useful to put this in separately. I've made all the pieces and arrayed the shingles. So it's not necessarily going to be a long process but the waterproofing is going to be the most important part of this deck. We've got the insulation and the stiffness. That's gone in with the boards. We obviously need things to fix too. We haven't battens in this, this is a shingle roof. So not a cedar type shingle but the asphalt shingle. It's very popular in the states. So if we come down to the roof deck breather membrane, this is our, sort of, layer of Gore-Tex as it were. This is going to be Tyvek, made by DuPont, who make Gore-Tex as well. So this is just going to be a thin little layer. This just gets wrapped over the roof. I think it's also called house wrap, that sort of stuff. We'll just drop this into place here. So this is going to act as our breather membrane. So any water moisture either gets through the asphalt shingle. That's not going to be penetrating this. But water vapor will be able to come through this roof from the inside. Okay, so that's the way that the breathe membranes work. And then if we go up to the As for asphalt shingle array and then we just drop this in, so pop it there. You kind of line it up from this corner. So if we just put that onto the top there and then that should be enough. It just, sort of, lifts up a little bit because we have got a few layers of this. That should be fine for now, you can readjust if you want. But now we've got the shingles on the breather membrane on our OSB. So we need to fix this down to this and manufacturers recommend, sort of, between four and eight nails per these things. They often use those, sort of, compressed air guns to fire these things into place. Very important that you don't hit a point where the seam is. Otherwise, you may have to rip it out and start again. So you can't have a little hole under there. Every hole needs to be under one of these, sort of, flaps. Okay and they are just thin bits of asphalt cut to shape. They've all marked up with various positions and also the Tyvec will have lots of different lines on it so that you can line these things up as well. So that's that, we've got the OSB, the insulation, another layer of OSB, then more insulation underneath. We're going to have another layer of OSB under here. And then we have our vapor barrier, battens, and then our timber finish. Okay so the whole process is going to be quite a few things because there's never just one thing. There's always, always lots of different bits. Okay so next up, we're going outside to deal with this thing, this is the soffit. And I'll see you in the next exercise.
