" This is where our clapboards come together with the shingles and with our arched top window. Let's talk about the window first."

" Yeah. Okay."

" How do you go about trimming out a round top window like this?"

" Well, the first piece is just a flat casing that I got off from someone by a 10."

" Yeah."

" With a template."

" Yeah."

" I took the template to a local lumberyard. They've got a nice shop set out down there."

" And they cut this piece here off in 2 pieces."

" So it makes sense not to try to do everything yourself especially if you're working with we're just gonna have a profile like that. Okay. And you're ready to pick up a lot of time on it. You're ready for this final piece here or the next to the final piece."

" Let's just bring this down to the bottom here and pre-drill this holes 'cause we don't want to be splitting this wood at this point in time."

" What do you do when you get to end? There is a miter."

" When we pull the joists together, we'll go down to a 4-penny nail."

" Okay."

" The same purpose. Final blow on that."

" It's a nice detail."

" It is. It is real nice."

" Now for something like this to last, you got to make sure you don't get any water in behind it, and this is where flashing comes in."

" Correct."

" Now is this like a window flashing that's on here already?"

" That is exactly what that is. That's a 3 quarter-inch window flashing."

" This is zinc."

" And that basically goes over that freeze board as we call it."

" That's right."

" Which is a 1 by 6 that will give us the transition between the clapboards and the shingles. "

" Yeah."

" Now the rest of the window trim will actually be flapped using sheet lead."

" That's right. We're gonna switch over to lead right at this point here."

" Because it is contoured at the top and the zinc is not pliable. You can't shape it."

" Yeah."

" Lead, you can, is easy to shape."

" The main reason is that you can buy sheet lead in a roll and you can cut the pieces you need and fit it around curves or scallops or whatever the details might be, and all of this lead gets hidden behind shingles and clapboards. There are tiny bit of it which is actually exposed to the weather, but it prevents any wind-driven rain from getting in behind the window trim and into the."

" Exactly."

" Into the side wall. And you don't have to worry about lead contamination when you're putting just such a tiny amount of lead."

" No."

" Here. I'll hold it for you."

" Thank you."

" Now there you're just tacking it on with a galvanized nail."

" Right."

" With any exposed nails, you'll use copper, right?"

" That's correct."

" Yeah."

" We'll just get some here."

" Okay. Now the entire side wall here in the gable end is gonna be done in scalloped shingles. "

" That's correct."

" Which you've pretty cut, but our starter course is just regular square cut."

" Right. Okay. Now we're ready."

" Now, Riley, how did you cut all these scalloped shingles? "

" We just made a template out of one of them and ran them off through the table saw at 4 and 3 quarter inches, and then took this off with a jigsaw."

" Riley, why do you make them all what was it? 4 and 3 quarters?"

" 4 and 3 quarters. Well, let's just say the uniform length to get them right. I checked a few houses out here on the island. That's what they all were."

" And that's a good dimension."

" Yes."

" And it's important from the point of view of the whole when you finish it and having it look the right proportion with the rest of the house."

" That's right."

" And you're only putting 1 nail a piece in?"

" That's just to get them off. Now this comes back a lot quicker. They just come back and nail the other side all at."

" Once they're all in place."

" So the white piece of wood that you see there is what we call a ledger board, which guides the bottoms of the next course of shingles, and you're starting with a half a shingle there."

" That way we're sure to break over all of our joists."

" And basically all the shingles are the same size in terms of the width, but what about the exposure to the weather, Riley? How do you figure out on the gable end? What's your main consideration?"

" Well on this, main consideration is that we hit the top of the window with the full course."

" Okay."

" So we've measured from here to the top and we know that's about a 2 and 3 quarters."

" So we've figured it out mathematically that at 9 courses at 4 and 3 quarters of inch would put us right where we want to be."

" That's how you figured out the exposure to the weather."

" Yes."

" 4 and 3 quarters of inch."

" That's right. Don't want to be any more than 5."

" Okay."

" 5s are out. Good."
