The Pitches, Trusses and Framing of Roofs

Whether you’re going to be directly involved in the installation of roofs or you’re just going to tell your requests to the roofer, a basic knowledge about roof design is important. The roofer can give you suggestions but you’re the only one who has the final say because it’s going to be your house anyway. So basically, roofs can be flat (still slightly angled) or pitched (really angled).  

You can easily tell the basic design of the roof of your neighbors. Pitched or flat, there are a lot of designs and combination of design elements you can choose from. With the right construction method, which the roofing in Sandy Springs will take care of, you can achieve the roof that your house deserves.  

 Framing of Roofs

As a start, let me tell you about the four main designs of the pitched roofs. These are the (1) gabled, (2) hipped, (3) shed and (4) mansard. There are many themes which are built in different ways using different materials. The gabled pitched roof is a piece of wall where the roof slopes around. The hipped is the joint between the roof’s adjacent slopes. If the roof is complicated, it will need several hips. If you prefer simple, you can opt for shed. But mostly it is used on lean-to structures. Finally, the mansard is the modified pitched roofs which create a space in the roof area.  

Frames of Pitched Roof 

This type of roof design will need lots of frames to support the covering and structure. The two main types of the wooden frames are trussed roof and cut roof. Most of the time they are combined to achieve the complexity of the roofing.  

Cut Roof Frame  

All roofs are basically “cut”, the carpenters cut during the construction. Some of the roof’s weight would be transferred to internal loadbearing walls to cover some spans. It is laborious, but still it is constructed even up to these days.  

Common Trussed Roof Frame 

These are manufactured by special companies because of their complexities. It is often referred to as A-frames, which combines joists, rafters and jacks. Because of technology, trusses are made slimmer than the cut roof. The stresses and loading requirements can now be calculated. Trusses are also available in different sizes and shapes to suit the roofing’s various needs.  

Like mentioned, trusses are manufactured in different sizes and designs. Some designs are for a particular type of roof or structural need. Some of the common types of truss roofs are room-in-attic, scissor, clerestory, and triple howe.  

Types of Roof Systems 

There are two basic types of roof systems, they are the truss frame and stick frame. The truss frame uses pre-built woods to build the frame. You need to be familiar of the pitch of the roof to be able to successfully build the roof system. The stick frame uses dimensional and ordinary lumber to create the frame and system.  

This information is just basic. It would be easy for you to familiarize them. But most especially, you should trust your roofer because they are skilled in this job. They know all about the pitches, the frames and the designs.
