all right so now we're going to hit the sidewall as we we were talking about on the end wall condition a sidewall is whenever your panels are running with the wall so in this case our ribs right here running right up against this wall so this would be a side wall so again we want to make sure that we get the right trim by using the right terminology now in this case we're going to show what kind of side wall trim date so what we're going to do on this particular detail is we're going to use an expose fastener installation and on the other side we're going to show an installation with hidden fastener okay so the trim that we'll be using today is this particular trim from American building components it'll close off the wall and protect the top of the panel so water can't run down the wall beneath the panel and into the roof okay so this this is just a 90 degree angle that's right and the ribs are going to fit in here that's correct and another term for this would be a step flashing so it's kind of like a step to water hits it comes off and off the roof all right well let's see how this thing goes together so as Jonathan just said we're going to install this step flashing here against the side wall the first thing that we're going to do is I'm going to let it run you can see that I'm letting it run past the end of the roof and pass the ridge line what I'm going to do is make marks on the reverse side of it so that we can take it to the table and finish it so that it closes off both the ridge and the eave so I'm going to make my mark marking this the end of the wall and the end of the panel so that I know where to cut and where to fold and I'll do the same thing at the top of the wall here now that the trim has been marked we can take you to the table cut it and bend it I've made marks on the reverse side of the trim so that I know where to cut it and where to bend it and I'm going to go ahead and start making those lines and tracing out my Bend and cuts this is the eave end and I'm going to remove some parts and fold down others and every one finishes trims differently so don't worry if you've got us if you've got a different idea that's not a problem I've made my cuts in my folds at the event to box off the detail along the end of the panel and what I'm going to do now is I'm going to finish the ridge I made my traces at the ridge I'm going to make a few cuts now so that this piece can fit underneath the ridge cap when it comes time to do the ridge and switch it over in this case if the ridge there's no need to box it because we'll be installing a ridge cap that will close the end of it off now we have the ridge end finished we have the eave end boxed off now we can go and install it on the project so let's just make sure that this fits we can see here that it fits nicely at the eave and up here at the ridge it fits nicely as well all the angles are good so I'm going to remove it apply tape seal to the nailing flange and then we can install it using an exposed fastener before we install it I want to point out that I've applied the tape seal to the reverse side of the nailing flange I'm going to remove the backer you'll see that the tape seal is about 1/2 of an inch in from the edge of the flange and I've done that so that when you tighten this to the roof deck the butyl tape doesn't squish out and become visible on the roof so make sure that you place it about 1/2 an inch back on your nailing strip so the trim piece is in place and using exposed fasteners I'm going to install it so something to be careful of when you put your first fastener towards the eave you want to make sure that you don't put your fastener so low down that your hanging over the eave trim you want to come up high enough that you grab the wood deck so I'm going to put the first fastener in so we've installed all the exposed fasteners you can see them running up the nailing strip and I just want to say one last thing now that this piece is installed you can see that the trim has been installed against new construction as I've said before this new construction would be covered in a house wrap such as Tyvek oftentimes if you're installing in a reroofing situation you're going to be coming up against vinyl siding brick wood in those instances the the best thing to do is to remove the siding and run the flashing up against the wall and replace the siding so that you have a watertight finish for this application we're going to use a hidden fasteners sidewall trim which is going to be this l-shaped trim attached to a Z trim so the first thing that we want to do is we need to figure out where to put the Z trim on the panel so I'm going to take my finish trim I'm going to put it against the wall I'm going to make a couple of marks on the panel and that way I know to set my Z trim about a half an inch back from my marks so this is the Z trim that you've been seeing throughout this project we're going to install it on the roof and then we're going to attach the sidewall trim to the Z using pop rivets and we always want to make sure that the paint side of the Z trim is facing out so that when you look at the roof you see panel Z trim all with the same paint we have the right length of z trim we've made our marks on the roof and I've applied butyl tape to the underside of the Z trim and just make note that I've left about a half inch gap between the tape and the leading edge of the Z so that when I fasten it down it doesn't squish out and become visible on the roof as I install the Z trim a quick note that you should back it up a little bit from the edge of the roof so that it doesn't get in the way when you want to bring your trim down so I'm going to go ahead and fasten this using pancake head fasteners making sure to thread the butyl tape as I go I can install these fasteners approximately every foot going up the z trim the Z trim is installed and I've made a mark in sharpie just to point out that I've placed the leading edge of the Z trim approximately one half of an inch back from the marks that I made on the panel and I do that because I don't want the edge of the Z trim to stick out when we install the sidewall flashing so by keeping it half of an inch back we ensure that it's going to be hidden so now we can go ahead we can put our sidewall trim up make our marks for cutting and folding and then we can install it so this is the sidewall flashing from American building components it's a standard El trim and this is the trim that we use most often in the concealed fastener or hidden fastener application so I'm going to put it up against the wall get it in place so that I can make my marks what I'm going to do is I'm going to mark the reverse side of it for the sidewall and I'm going to mark where it finishes at the end of the panel for bending down and here along the ridge I need to mark where to cut it so now that the trim has been marked we'll take it to the table and make our cuts and our bends and then we'll come back and install it so you can see here that on the reverse side of the trim I've made some pencil marks these are going to be my fold and cut lines I'm going to go ahead and I'm going to prepare the end of this so that it's boxed off nicely at the eave I'll finish the top at the ridge and then we can go ahead and install it we're going to go ahead and install the trim by attaching it to the Z trim using pop rivets before we do that though we need to apply tape seal to the top side of the Z so that we can install this for a weather tight finish so we're going to apply the tape seal to the top of the Z trim and I'm making sure to set it back about half an inch from the leading edge so that it doesn't squish out when I install the trim now I have the trim in place you'll note that the Z trim at the top you can see that it's well back from the leading edge and now I'm going to go ahead and use pop rivets to install this making sure that I drill my holes for the pop rivets in the outside flange of the Z trim and not behind as you're drilling the hole for your pop rivet you want to make sure that when you go through both layers of Steel the drill is going to want to pull you down you don't want to punch a hole in your panel so ease off a little bit as you feel yourself going through that second layer we're using standard 1/8 inch pop rivets that have been color matched by American building components to match their panels so we're going to go ahead and install that here making sure to grab both the Zee trim as well as the sidewall flashing and there you can see that the sidewall flashing has been secured to the Zee trim using the pop rivet I'm going to go ahead and install the rest of the pop rivets so that we can finish this off as a true concealed fastener installation all of the pop rivets have been installed so the sidewall trim is now ready to go we have a true concealed fastener installation I want to point out one thing when you're drilling the holes for your pop rivets metal shavings naturally you're going to fall on the panel and on the trim you want to make sure that you try and brush as much of that away as possible you can blow it away you can brush it away with your hand or a broom just to make sure that those shavings don't sit on the metal and rust so this sidewall like like all sidewalls and then walls you're going to be coming up against either new construction or an existing construction in this case new construction normally there would be a house wrap or a Tyvek on this for siding and wood it's best if you can go behind in the case of brick you would want to cut a reg let in the brick and insert the flashing into that regulat so that concludes this trim concealed fastener sidewall installation you you
