howdy folks, Kirk and Jay here with Kirk Giordano plastering, today I'm gonna explain something
that most of you probably won't ever need to know, but you GC's-"general contractors" and roofers, pay attention guys.
This is a third time we got beat up this month with goofy stuff happening on roofs
and walls. If you can get in here, you see this piece of metal guys this piece of metal is on
top of the wood but there's nothing protecting the membrane of the roof there's a torch down.
now technically, they should have a saddle in here the saddle goes under here and comes out and goes over this
part that protects the roof now we're in San Francisco, we're about three-four stories high
and we are facing south. Right now it's kind of a chilly day but we're gonna get some high winds
in the winter probably 80-90 mile an hour winds here with the rain, it's gonna cause the rain to
go upwards, so everything has got to be protected. well. Now the fella says, a couple people said to
me already at least three times this month, it's getting old, they say, well can we use a peeling
stick like okay, there's a lot of peeling sticks, there's a Fort-a-flash, that's a fort-a-fiber,
they got straight flash peel and stick. I said no you can't use that because on a roof, it can get
baked with the Sun and a peel and stick like one of these will last about 30 years maybe, but then
they start pulling away water moisture gets in it. I mean, I won't be around in 30 years, but metal is
what is code. So you got to go with metal guys, the metal lasts forever, I know I've got a hundred and
twenty-year-old house in the metal on my window frame is still intact, so guys when you're doing
your roofs sheet metal guys, contractors, make sure you do the right saddles I got four of
these, that's why I'm pushing this issue and then they say well gee, what about this, and caulking it?
Caulkings are pretty good guys, but they have a specific reasoning behind them, I'm going to show
you what that reasoning is, because again this is a really busy job guys, we're, fortunately, the
scaffold set well. They got a few other things going on and as we go, we correct what we can,
the roofers coming back later today to do that, and he says, "Kirk, can't you do it," I said man, doing you a
favor because you'll learn from this job, not to do it on the next job and get sued. But if you get sued on
this, you're going to drag me into it. Now as far as framing to you guys you don't want to, the same thing
as they did there, you don't want to put your crown mold or any of that right into the wood these guys
did it and then they put a caulking on top. Wrong guys! That's not what caulking is made for, okay,
what I did is I just went home. This was Friday we were here. It's Monday morning now about 8 o'clock
in the morning, and I just took my Sawzall, and I cut it right here, that way we can waterproof it
properly. I mean these moisture barriers, barriors guys, I can't stress enough how important they
are, they've got a lot of issues going on, but I'm gonna try one out of time. okay, now that I cut all
this here now what we can do is put our moisture barrier under it, and again this is two layers
so it's just say for example that's, okay that's for example guys, I'm gonna put another one now,
remember I cut this I still got to cut this nonsense off, but for the sake of showing you
guys what caulking is really used for. I'm gonna do this right here and then I'll fix up my own
little work soon enough, okay, here's what caulking is for guys now that that's on we have a moisture
barrier under these two layers of sixty-minute paper can you use peeling sticks absolutely but
that's another story. Okay, now that we've got this on, unlike here where they caulk this, to the frame
that's wrong! It will leak! It's just a matter of time, if it leaks then we all got to come back and
fix it. and we're three stories high which means, scaffold has to be set again, there could be a
$90,000 mistake that's a $90,000 boo-boo guys, All right now, here's what caulking is for, and there's
a lot of caulking guys. I'm using a Sikaflex-one-A, What does that technical name? means, that's just a
polyurethane adhesive sealant. Now that's what that stuff is for. Another thing guys, just to prove
a point. When I get to job sites in the future, and I walk them, I'm gonna send the contractor this
video, when it's got roof details like this and say, make certain that it's done this way. All your
window sills should be cut, so we can slide paper underneath it. Not right to it and caulk it that's
not the proper procedure. When you have a wall like this where it's old and it's dried out,
not a big deal we put four layers over that, that way we're certain it's not going to leak lastly I've already
gone through two rolls of this stuff here it's a peel and stick, they have it in 30-mil and 50-mil. So
you can get thick stuff or the thin stuff. Here's another thing what we're doing because
these are arches their radius details, they're all over this job and they're beautiful, very beautiful
their radius details here, they had this was done really nice by them they had their peel and stick
here, and what we have done is we put two more layers up as high as we can get it, which is about
here that is that works but we go the extra mile guys, then I after we fish our paper underneath
we put another piece on top, and go as high under here as possible, they are going to put a trim board
here, so we're stuccoing right to here and to here, and here, and then he puts this trim board
here, that's another topic for another day. When you have these details here guys what I've done
is I've reflashed their flash, I've counter flashed they're flashing and then I'm gonna put because
it's an inner detail here and when we got here it was kind of kooky, we took our paper here went to
hear it and fished it back and now I'm gonna put another piece right on top guys, you cannot be too
secure with a roof that's four stories high. How many boxes of caulking do I have for this? I have
two cases and they're like two-three hundred bucks a case, that's cheap compared to coming
back a second time. I found this in the trash can which means this is what they used and this isn't a
bad caulking guys this is a forty-year plus, but it's not the proper caulking for a roof detail,
garbage for a roof, but it has its great purposes you use a polyurethane caulking for stuff like
this. because it's an adhesive sealant, guys. That's pretty important for moisture barriers, anyway what
we're doing next is of course we've got a drip these put as a J flashing on them and as we
do that, i'm putting another barrier on top of the paper because these are going to get hard hit hard,
with high winds of 70 to 100 degrees, everybody's heard that all saying,
"The coldest winter I ever spent was the summer in San Francisco," I'll tell you, it's true, because I'm cold right now and
it's summertime. Anyway guys thought we'd show a few details in regards to roof flashing counter
flashing. Caulking and moisture barriers because they're pretty important guys if the job leaks,
it's no fun for nobody. Anyway we thank you folks for watching and as usual, we'll see you guys on the next one.
