Wooden Roof Frames
The Complete Guide To Wooden Roof Frames
A roof can be flat (slightly angled) or pitched (angled). The majority of roofs that are on homes and other structures are pitched, and many of these structures have wooden roof frames. There are various types of pitched roofs that are suitable for various situations. This means that there are several variations of the basic design of these roofs, and the design elements can be constructed using several methods.
Before you begin to work on a roof, it is important to understand the elements that are necessary to have in place to ensure the roof is waterproof. However, this will vary depending on the climate, age, design and the choice of covering.
A roof is supported by interior bearing walls, ceiling joists and outside walls. Roofs are also covered in layers of shingles, plywood and waterproofing.
What Are The Different Types Of Pitched Roofs?
Pitched roofs commonly have four main designs, and these themes are varied. A roof is generally described based on their shape. Every type of pitched roof can be built differently, and can be built with different materials. Some frames may be made of metal, while other buildings have wooden roof frames.
The Shed design is the most simple type of pitched roof because it only has one slope. This type of design is typically used for roofs that are part of lean-on structures like additions.
The Gabled design has slopes on the roof that go around the triangular extension of the last wall. That particular piece of wall is known as the Gable.
The Mansard design is a modified or hybrid version of a pitched roof. This design creates a spacious living space under the roof.
The Hipped design has a joint or hip between the adjacent sides of a slope. The more complex a roof design is, the more joints it has.
The Different Materials Used In A Roof Covering
The different aspects of a roof that are described below are considered standard on the majority of roofs, and these are the parts that are necessary to help the roofs shed water correctly. The materials must also overlap in the same direction. Roofing materials are generally installed from the bottom towards the ridge so lower layers of materials are overlapped with the next layer of roofing materials.
Most roofs that are installed have shingles or other types of tile like covering for waterproofing. This process can vary, and there are different ways to overlap the materials including felt (underlayment) and battens.
Sheathing is a type of overlap that is often required by local building codes. This adds a rigidity to the wooden frame of the roof as well as a surface for nailing fasteners. Particleboard, OSB and plywood are some of the most common materials used in the sheathing process.
If shingles or wood shakes are going to be installed, you may want to consider add some space in the sheathing for more ventilation. This will help to dry out wooden materials after rain or snow.
Most residential structures use wooden roof frames. This guide provided some basic information about materials used during the roofing process as well as the importance for including these materials.
