Step 20 - Entryway Trellis, Part 2

After the 8x10 beam was put up and the four 6x8's were laid on top of that, the trellis now gets two layers of 4x4's. The first set are long ones that run parallel with the 8x10 beam. They are the three pairs shown in the photos. The second set are shorter and run parallel to the 6x8's. Not all of the second set have been put on in these photos. When they are all in they will go all the way out to the end of the trellis.

The part of the trellis closest to the front door is covered by a small area of roof for weather protection. This roof is only 8 ft. x 12 ft. but it was very complex to build. First, a layer of decking was put on top of the 4x4's. The decking is 2x6 tongue and groove spruce where it will be visible from underneath, and plain 2x6 Douglas Fir where it will be covered up.

It's tricky getting a small, flat roof like this to drain properly, so Pat Sheehy gave it a special design. A tapered ridge board runs diagonally across the decking, and tapered framing was added all around to fill it in. Then plywood was nailed over the whole thing. The result is a roof that will shed water in two different directions. All these layers of trellis and roof had to fit into a tight space that also contains the roof coming off the garage and its exposed rafter tails. It was quite a bit of work for Mark Stanfield and his crew, and they did a great job of it.

There is still more to be done on the trellis. It will need a hot mop roof (more on that later.) The painter, Mike Glenn, will be coming to stain all the exposed wood. We already stained some of it because there are areas that would be difficult or impossible for Mike to reach after it has all been put together. The final step for the trellis will be putting a special copper adhesive tape over the tops of all the trellis members. This will prevent water from getting into the wood and rotting it.
