The house will have an 8-foot-deep nearly flat roof over the terrace. It’s kind of like a store-front awning. The architects designed it to be supported by four tie rods, which gives it a cool look, and avoids using any columns to support the edge of the roof. Of course the problem is that this structure has to be designed to handle all the snow from the roof above landing on it in an avalanche. So, it’s incredibly beefy and ties into big steel columns in the walls. This feature of the house probably cost about $10,000 more than a conventional “porch roof.” Still, I can’t imagine a better use of $10,000 in giving the house a distinctive quality.
The framer, Jose, and I had been staring at the big pile of steel, fasteners, and tie rods for a couple of months now. We finally tackled the project yesterday morning. It went pretty smoothly. My calculations came out perfectly on the rod lengths. (Thank you, Pythagoras). The only minor obstacle was that the engineers had specified very long bolts to go through the wall. However, independently, they had located a bunch of steel plates in those same spots which would impede the insertion of the bolts. So, in a couple of locations we substituted shorter lag screws where it would have been impossible to go through the steel plates in the walls.
There will be chunky timber purlins that run horizontally and then the same corrugated steel panels as we use elsewhere will form the roof cover. More pix when it’s done.
The next week Jose and his guys put up the 500 lb. c-channel which goes on the ends of these supports.
