Framing Front Eaves

I've finished up the framing for the eaves and soffit supports at the front of the house. Now I can lay down the final piece of roof sheathing on this side of the dormer opening. Things are actually moving along.

Interlocking Rafters

The lowest lookout rafter and the last rafter tail are a bit tricky to construct because they need to share the same space at the low end of the end gable wall. They need to cross over each other to be long enough to properly support the corner of the roof.

To resolve this problem, I notched out the top half of the lookout rafter and the bottom half of the rafter tail (actually a double tail). I installed the lookout rafter first, then placed the rafter tail over top. Finally, I attached a small steel plate (similar to what's used to hold trusses together) on top to tie everything together.

West Lookout Rafters

I've finished all the lookout rafters on the west end of the house, except for the topmost one. I'll have to wait for the snow on the peak to go away before I can finish that one. Next up: roof sheathing.

Scaffolding Set Up

I've got the scaffolding set up so that I can start work on the lookout rafters on the west end of the house.

Girder Reinforcement

The engineering specifications for the main roof girder required that an additional 2x10 be attached across the bottom on both faces of the girder. Here I've added the 12' middle section.

To install it, I attached a couple of long clamps to the bottom of the girder, then rested the 2x10 on top of the clamps until I had it nailed in place. It's attached with 3 rows of nails spaced 6" apart.

Supporting Plywood On The Roof

My house is basically divided into two sections; a small section (dining room on the main, bedroom upstairs) and a large section (everything else). The roof trusses above the small section are spaced on 16" centers. The roof trusses above the large section are spaced on 24" centers.

When sheathing a roof, the plywood must be supported along the edges between the trusses. For the small section of the house, I used H-clips. They are in the shape of an "H", and you place them between the sheets of plywood between the trusses.

For the large section of the house, I've used a more old-fashioned method of nailing a length of 2x4 between the trusses. The edges of adjoining sheets of plywood are then nailed to the 2x4. This provides a bit more support than the H-clips, particularly when the trusses are spaced farther apart.

More Roof Sheathing Done

I've got a bit more sheathing done at the front of the house. It's so nice to have the sun back again. For a few weeks during the dead of winter the sun is low enough that it's behind the mountains and I don't get any direct sunlight.

Non-glamorous Work

I've been doing some rather non-glamorous work lately... bracing trusses and general cleanup... neither tasks worthy of any photos. Such is life sometimes.
