Gable Finish. We have seen that when a dormer window is designed with two sloping roof surfaces, there is thus formed on the front of the dormer a triangular-shaped surface which must he decorated in some way and which calls for a certain amount of fin ish. The same thing is true of the main roof when this is designed as a gable roof, the triangular surfaces at the ends of the building being known as "gables." The problem which presents itself here is to treat the lines in which the roof surfaces meet the vertical wall surfaces at the ends of the building, and to cover up the rough timber of both the wall and the roof. The most simple way of doing this is to miter the gutters at the sides of the building at the line of the eaves with a raking molding which will follow the line of intersection between the roof surfaces and the gable wall. In the plainest work this raking molding will not project much beyond the wall line, only far enough to miter properly with the gutter. Fig. 299 shows a very simple gable end of a building with no finish except the raking mold ing, referred to above, mitering with the gutter at the eaves. In this figure, C is the raking molding, D is the gutter. In Fig. 300 is shown a large-scale section taken through the raking molding where marked section A-B in Fig. 299. In Fig. 300 A is the raking mold ing, B is the roof shingling, C is the roof boarding, D the rafters, E the end studding, F the outside boarding on the end wall of the building, and C the fascia below the raking molding. The molding is so arranged that the roof boarding stops against it and the roof shingling passes over it and projects a little beyond it so as to form a drip as shown at K in Fig. 300. In the space marked II is blocking consisting of rough pieces spaced 2 to 3 feet apart and shaped to take the back of the molding.
There is an awkward place at the point marked B in Fig.
299, where the line of the gable meets the vertical line of the corner of the building, and some finish is usually placed here to overcome this awkwardness. In
the small gable on the end of the dormer shown in Fig. 296 the fascia is carried across the face of the gable as well as along the raking line of the roof, and this arrangement is sometimes adopted on larger gable ends, but a more common practice is only to start the fascia across the gable end wall and then return it on itself a foot or two from the corner marked B in Fig. 299, stopping the raking fascia on top of it. This is shown in Fig. 301. A better result is obtained by returning the gutter mold ing as well as the fascia. The top of the return marked A in the figure should be sloped outward slightly so as to shed water. B and C are additional fascia boards which are added to give additional width to the raking moldings.
Ferge Boards. It is a common practice to use what arc called "verge boards" for the finish of the gable ends of ings. These are a kind of ornamental rafter which follows up the rake of the roof, not along the wall but some distance from it, being held in place by lookouts which are nailed to the studding or to the boarding and placed at the proper distances apart. The verge hoard forms a stop for the gutter and furnishes a very suitable finish for the gable. It is usually crowned with a raking molding of some sort and is, there fore, only a big fascia. Fig. 302 shows a verge board in elevation at the point where it joins the eaves, and Fig. 303 shows a section through the verge board and the end wall of the building showing how the board is supported by the lookouts. In this figure, A is the verge board, B is the raking molding, C is the blocking which forms the lookout, D is the outside boarding of the wall, and E is the shingling, F is the roof board ing, and G is the roof shingling.
