Building Joists and Rafters

Ryley and Bob discuss the special beam being installed which utilizes a fletch plate. The plate is made of steel and is then sandwiched between two pieces of wood for added strength. Bob assists in bolting the plate to the wood and then securing the beam in place. The remaining joists and rafters are then added.

" So, Ryley, what do you up to now?"

" Well, I've got a little something special here Bob. This is a grit we're going to put up to carry the second floor."

" We're talking steel here, aren't we?"

" Yeah, this is a steel plate. It's actually called a fletch plate."

" A fletch plate."

" A fletch. "

" A fletch plate."

" Fletch plate, F-L-E-T-C-H."

" And you're sure about this?"

" I would take my reputation."

" Did you look it up in the book?"

" I looked it up in the book and it is the fletch plate."

" It's half in steel?"

" Yeah."

" And you're sandwiching it with a couple of piece of 2 by 10?"

" Correct."

" And basically, you're creating a very stiff and strong beam that's gonna carry roof logs?"

" This is gonna be carrying, yeah I see. The part of the second floor coming with this joint, coming across this right here what we're going into this."

" Yeah."

" [unk], which goes across this way."

" Yeah."

" We'll also have the roof coming down on top of."

" Correct."

" You do not see the entire roof log----"

" Yeah."

" because you can spread it out some."

" And it's---- What about 10 or 12 feet?"

" This is, yeah, 11-foot."

" Yeah."

" 11-foot 10."

" Okay, it's not over to you?"

" No, I don't think---- and probably a 3 or 2 by 10 might very well do it----"

" Yeah."

" but this is, we're on the safe side, doing a safe thing [unk]."

" This was not a waste of money. How much money did this cost?"

" This is 96 dollars in change."

" Primo, yeah, why not? Okay. So, you're just in the process of bolting it together here right?"

" Okay."

" You [unk]. Go in."

" Right."

" Okay, let's do it here. Yeah. Okay, with the hangers in placed up here on out header, we're getting all of our second floors really secured."

" Okay, the first wrap is ready to go upstairs."

" So, put down."

" Okay, got it."

" Got it?"

" Yeah. And we always nail the bottom down first to make sure it doesn't fly away on its own."

" Alright."

" [unk]."

" Okay, I got it."

" It's good up here."

" Okay, there goes the last one. And we've got them checked in the place. We have to put 4 or 6-penny common nails or spikes as they're called. Up at the top there at the ridge and 4 more here at the bottom, at the crow's foot and then, they'll be secure."

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.

Could someone tell me where I can get information about fabricating a Fletch plate? I saw it done lond ago on one of the "This old House" or "Home Again" shows (years ago). I am now considering…

Fletch plate

A flitch plate is generally made from thick plate steel. It is them punched out or drilled with two offsetting rows of 9/16 holes about 12 O. C. at the top and bottom 1 to 1 from the edge. This plate is then sandwiched in between 2 - 2xs and through bolted with machine bolts with washers.
