How to Install a Bay Window: Part 2
With the roof built, it’s time to tackle the installation
In part 1 of this two-part series, Rick Arnold began a bay-window installation by building the roof on the ground. In part 2, Arnold describes how to install the roof and the window. After setting up a two-level piece of scaffolding, Arnold and an assistant move the window into the rough opening from the outside. Then they temporarily secure the head board so that they can shim and fasten the window in place. After the window is secured, they insulate and install the roof. With the roof in place, they install stainless-steel cables to keep the window from sagging over time. The tops of the cables are attached under the roof, and the bottoms are attached to the seat board near the angled corners farthest from the building. The cable ends are accessible for adjustment later, if necessary. To complete the job, Arnold and his assistant install the flashing, the roofing, and the trim. This article has a companion video.
