Larry explains the type of roof and framing required to hold it up. He shows how the fascia board and how the roof is adhered to it. Bob reviews the earlier framing and beam placements to support the porch roof. The porch is thirty-two feet long and seven feet deep. Larry then explains how to marry the old roof with the new one.

Framing the Porch Roof

computer-generated transcript - may not be 100% accurate

" Ok. Well, last week we started building this wonderful farmer's porch on the front of the house which not only serves as a new entry to the house but really is a recreational outdoor room. We showed you how to build the deck framing which is all created from pressure treated lumber. And as you see it all, sits on these concrete, appears that are here. And we have a laminated beam that's 2 pieces of pressure treated lumber with some plywood in the middle and that spans the whole porch. Now, at this point, the new work that's already been done is that we have a post fasten down to the beam, 4 by 4 Douglas Fir and we have the top of the post also fastened to this newly crafted beam up here which is identical, it's also ---I gotta piece of plywood in the middle of it to give it additional strength and it goes the whole span of the porch and, Larry, if I can interrupt you how big is this porch, was it measured?"

" It's 32 feet long approximately and it's about 6 foot 9 almost 7 feet out from the house"

" That's gonna be spectacular, now you guys, I'm interrupting everybody, you're in the middle of getting started with the joists? "

" The ceiling joists, yes."

" Ok, and they of course can be just plain 2 by 6?"

" They can be 2 by 6 and they go in like this."

Engineered Wood Framing

Framing a house using engineered wood has many advantages. Glue laminated beams are stronger than their conventional solid sawn counterparts. (Laminated veneer lumber comes in smaller dimensions for headers and ridge beams.) Engineered I-joists span greater distances and their stiffness prevents squeaky floors. Oriented strand board sheathing prevents racking and provides good nailer for siding.

Discussing Efficient Framing Materials

Bob outlines the steps involved in framing up the house. Once the first floor joists were in place, the crew started in on the subfloor using ToughPly, a thicker plywood product from Georgia-Pacific. A single layer of ToughPly can be used under hardwood, tile, or carpet, and its quick-fit tongue and groove design saves time fitting the panels together. Next the crew framed the sidewalls with Riverside CDX plywood sheathing harvested from sustainable forests in British Columbia. While only slightly thicker than standard OSB or plywood, it's three times as stiff for a greater load carrying capacity and its favorable weight to strength ratio makes its easier to work with.

Framing with Engineered Wood I-Joists

Bob and Ryley meet up with framing contractor Kevin Parquette of Timberline Building Specialists. Kevin comments on the advantages of working with the 28 ft. long engineered wood All-Joists from Boise Cascade. Designed for high performance and stiffness, All-Joists significantly speed up the framing process. Next Kevin points out the 1 1/8" engineered wood rim board. For fastening Kevin's crew used 12-penny nails covered with a glue which is activated by the speed of the nail coming out of the gun.

Tour of the First Floor Framing

Bob tours the newly opened up first floor of the house and the turns his attention to the little family room addition. The wall has been bumped out a couple of feet and at an angle. Bob flashes back to the construction of the new addition. The carpenters began by framing the deck with pressure-treated 2 x 10s anchored to the existing frame and set on concrete footings in the ground. The framed the walls with conventional 2 x 4s and attaching plywood to stabilize the structure. Then they framed knee walls to supports the windows that will fill in the corner of the addition. The second floor is now supported using LVLs attached to a 6 x 6 clear fir post which transfers the weight of the upper floors to a new footing directly below with the addition is framed around it. The effect when finished is similar to a greenhouse.
