  • Roof Framing
    CHAPTER 2 ROOF FRAMING In this chapter, we will introduce you to the Intersecting fundamentals of roof design and construction. But, The intersecting roof consists of a gable and valley, before discussing roof framing, we will first review or hip and valley. The valley is formed where the two some basic terms and definitions used in roof different sections of the roof meet, generally at a 90° construction; we will then discuss the framing square angle. This type of roof is more complicated than the and learn how it’s used to solve some basic construction problems. Next, we’ll examine various types of roofs and rafters, and techniques for laying out, cutting, and erecting rafters. We conclude the chapter with a discussion of the types and parts of roof trusses. TERMINOLOGY LEARNING OBJECTIVE: Upon completing this section, you should be able to identify the types of roofs and define common roof framing terms. The primary object of a roof in any climate is protection from the elements. Roof slope and rigidness are for shedding water and bearing any extra additional weight. Roofs must also be strong enough to withstand high winds. In this section, we’ll cover the most common types of roofs and basic framing terms. TYPES OF ROOFS The most commonly used types of pitched roof construction are the gable, the hip, the intersecting, and the shed (or lean-to). An example of each is shown in figure 2-1. Gable A gable roof has a ridge at the center and slopes in two directions. It is the form most commonly used by the Navy.
