It is often desirable, for the sake of architectural effect, to break the surface of the roof just above the eave line, and in order to do this it is necessary to make use of small pieces of rafters, called false rafters, or sometimes "jack" rafters, which are nailed to the ends of the regular rafters. In this case the regular rafters stop at the point where they rest on the plate, and the false rafters project out over the wall line as far as may be desired. These false rafters are cut into various shapes and are usually left exposed on the under side, being in this case made of a better and harder class of wood than that used for the regular rafters. The gutter may be placed on the ends of these false rafters if desired, but it is more usual to make use of a construction such as is shown in Fig. 285. Here it will be seen that the gutter is merely formed up on top of the roof shingling by a piece A which is held in place by the bracket B. The brackets occur at intervals of about 2 feet, while the piece A is continuous. The shingles which cover the roof are stopped on the strip C and the inside of the gutter thus built up is covered with galvanized iron, or copper, to make it water-tight. The ends of the rafters may be finished with a fascia as shown at D, and the space between the false rafters along the wall may be finished ' as shown at E. In place of the wood piece A which forms the outside member of the gutter, a piece of metal may be used to accomplish the same purpose, and this is often done.
