Building a Pitched Roof from Rafters to Shakes
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 ice and water shield 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.
