" We've been -- calling as a greenhouse conservatory as it's really a combination it's not you're working greenhouse does not just conservatory and anyway the structure cortisol in place and what. Looking at here is a series of rafters. Which are. Solid Carol -- beams that go out and a hole eighteen foot span up to the top of the existing roof and then in between that the horizontal members are called parlance. The top of the roof up there you can see we've got a new skylights already in place and these are very important part of the design because they will be. Are operable they can open up and very hot weather and allow the -- hot air that rise up there to escape the space. Now down here on the perimeter on the outer perimeter we have taken the lead coated copper and fitted it to the entire area so that we don't have to work worry for many many years about any kind of weather damage to the structure. And then of course we've got our vertical supports which are right now offered up with plywood we could take a better look at them from the inside let me jump in here. Okay now these vertical supports which really take the whole weight of the whole structure. Are actually tubular steel that's been galvanized. And we've heard some plywood on the front the outside of it because we are after all installing windows operable windows down here and we'll be trimming them out. -- noticed that the masonry work has all been completed. And it's a good feature here the architect called war. Our separation between the inside -- or brick in the outside courts are brick the outside -- the roller coarse the way we cut them that allows whether to just washed right off. The inside it's flat but in between we've stuck into some insulation and into this. Into this area which is really a thermal breaks that that you don't have the cold transmitting itself all the way into the space. These duck yellow lines here have been. Pulled through the existing up PVC conduit that we put in here which are for electrical feed us. Because -- won't do want to motorized these windows that will be installed here so that they can work. In tandem with the skylights that I showed you a minute ago to create a convection currents in the summertime so that you can ventilate the space. If you'll notice down the bottom it was -- blue stuff is our rigid insulation. And then I'm standing in the proper where will be installing our our heating elements. And then on the other side of the truck you'll notice that we still have a lot of this broken rock we have to feed this stuff in this material as an act as a heat sink. In the wintertime when the sun comes in here to the warmth of the sun would be absorbed by all of this which of course will be covered. With a couple of inches of stone dust and -- some fine native bluestone. Pavers it'll go in there. But right now let's this visit throw out with Riley who has been really don't have them very clever carpentry."

" All right Ryley let me interrupt you up there okay. You know this looks like a very simple little structure that your building is it's nothing more than out of triangular -- Doghouse dormer intersecting gabled roof right. That so when he visited and it does look simple from out here it's pretty straightforward right your -- standing more or less in the valley this is about it right here which direct transition rafter between one. One slope and -- the other slope. That's correct yeah and -- material that you're sheeting the roof with is not plywood what is it no this is a inch and a half by six inch. Ponderosa pine has been tongued and grooved with a V -- to finish side putting down. Yeah that's that's -- finished. And I noticed that it doesn't exactly match up with the existing roof it's lower than the existing roof of the house right -- that's totally gets an installation in here that'll give us enough room for two inches of the rigid insulation and then we can't just shingle on top of the rigid -- and you know don't put half inch plywood over that. You know -- on top of that okay. Now being. Challenging thing about this roof it's kind of hard to understand isn't it it's hot from out here but he can visualize a little better out hits of it was a very difficult -- to put in because not only is it we're. Is it explodes from the inside. But we have chew on -- pictures this is coming down and -- 1012 pitch. This little dog the dog house though it is coming out of the twelfth twelve pitch yeah so it's a different angles coming together at the same spot and it's exposed Downey as fast -- all mahogany I creating this pergola -- At a pergola really is -- garden structure that's meant to be open. Rafters that usually carry minds on top of them by creating this pergola hear the architect is related the structure to the garden. And also giving you a headache -- sick and as the the interesting thing is going to poke through it here is that the rope itself. It's way up there. And over here. But much of the cargo but is just floating free here -- say."

" Right exactly. The -- that trickiest part of this the way it was difficult. There's there's the valley raptor has to catch everything right where it intersects. The problem being. That this existing rupiah falls away at a 1012 pitch. Has to hit the value that angle right in this new gone that we put on flaws way to -- well it's. -- it also have to catch on of these rafters following ways to nail yes and since -- and mahogany and expose such epic just second Sharon doesn't mean the bottom of the valley rafters. Wasn't the same as the other rafters. The this bottom of this in the -- that's the other thing the architect conference he wanted it to be -- Flush finish as the wind -- so we kept seeing old these valleys rafters well."

Building a Pitched Roof from the Ridge Beam and Rafters to the Shake Shingling
Building a Pitched Roof from the Ridge Beam and Rafters to the Shake Shingling

Bob opens the segment with a look at the Certainteed Landmark shingles selected for this project. Fabricated with a dragon's tooth angle, the Landmark shingles give the impression of a handsplit shake roof. Next Bob flashes back to the construction of the roof. Starting with the raising of the laminated veneer lumber (LVL) ridge beam onto the gable ends, Bob walks the viewer through the various steps in the process - laying out 20 foot 2 by 10s for the rafters, marking a ridge cut at the top of each rafter and a crow's foot at the bottom, positioning and securing the rafters to both sides of the ridge starting at the center, applying the CDX plywood sheathing followed by an ice and water barrier as underlayment for the first course of shingles, nailing on the aluminum drip edge, and finally laying out and applying the first course of shingles. Once the first course is finished, felt paper is stapled to the rest of the sheathing as underlayment. After the roofers have finished shingling all the way to the top, they add ridge vents and soffit vents to prevent moisture from building up under the shingles.

Raising Gable Ends and Cutting Rafters for Wayland Second Floor Addition
Raising Gable Ends and Cutting Rafters for Wayland Second Floor Addition

Bob and Ryley start by raising an exterior wall on the second floor. Bob and Larry Landers discuss a stiff back support for a tall wall that will be both an interior and exterior wall on the same side depending on the height. They support the wall insuring it is plumb before starting on adjacent walls and rafters. Ryley explains the cutting of a nine twelve roof angle and how to use a framing square to get the angles for the rafters.

Cutting and Laying Roof Rafters for Vaulted Roof
Cutting and Laying Roof Rafters for Vaulted Roof

Bob helps lay the rafters on the roof of the home. The rafters all follow the same cutting pattern so they can all be laid into place. After two of the guide rafters are in place, a ridge pole is put in. The ridge pole supports the upper end of the rafters and is made of laminated veneer lumber (LVL). After the ridge pole is in place, the rest of the rafters can be laid down. The rafters have a bird mouth cut. Once plywood is laid on the roof's exterior, hurricane clips will be used to secure the roof.
