The roof is one of the most important parts of your house; There are two main types of roofs: flat and pitched.
Flat roofs are easy to build and very strong, while Pitched roofs are more difficult to build but more aesthetically pleasing. Each type of roof has its pros and cons.
The roof is one of the most important parts of your house. It protects you from the elements and keeps your home warm and dry.
Roof members
are the structural elements that support the roof; they include rafters, trusses, and joists. The type of roof member you use will depend on your roof; they are important because they support the roof’s weight and keep it from collapsing.
Without roof members, your roof would be fragile and could collapse in strong wind or during bad weather.
A good roof design and properly sized roof members will make your roof stronger and more durable, more resistant to wind and snow damage, and save you money on energy bills.
Roof Trusses
Roof trusses are the framework that supports the roof of your home. Typically makes them from wood or metal and space them evenly along the length of the roof.
The Roofing Material
The roofing material is the outermost layer of the roof, and it is what you see when you look at the roof. The most common types of roofing materials are concrete, metal, and clay tile. Metal roofing, most common in Nigeria, is durable and available in various colours and styles. Clay Tile roofing is available in a variety of colours and styles, and it is very durable.
Roof Members Types
Tie Beam
Tie beams play an important role as a structural element in buildings, providing support and stability by transferring loads from the upper floors to the foundation. Typically, people construct tie beams using concrete, steel, or timber materials.
People often use them in construction to provide additional support for a beam or truss and roofing, supporting rafters.
The different types of tie beams
Construction utilizes several different types of tie beams, including:
Concrete tie beams are made of concrete.
Steel tie beams are made of steel and are often used in high-rise buildings and commercial and industrial buildings.
Timber tie beams are the most common type of tie beam. They are typically less expensive than metal tie beams but are not as durable.
Metal tie beams are more expensive but durable and have a higher load-bearing capacity.
The advantages and disadvantages of each type of tie beam vary depending on the application.
Rafter
A rafter is a horizontal beam that supports the weight of the roof. It is typically made of wood but can also be made of metal or concrete. Rafters provide many benefits to a home, like adding strength to the home, helping to keep the walls of a home from bowing out and providing a place to install soffits and fascia.
Purlin
– A purlin is a vertical beam that supports the roof’s weight. Purlins are typically made of wood but can also be made of metal or concrete.
Roof noggings
they are installed at the eaves of a roof, where the roof meets the wall of the house; they are also installed at the ridge of the roof, where the two slopes of the roof meet.
Roof noggings help to receive the ceiling finish, and they also help to keep the ceiling and roof from sagging.
The Types of Roof Noggings
There are two main types of roof noggings: wood and metal.
Wood noggings, made from pressure-treated lumber to resist rot, are the most commonly used type of nogging.
At the same time, Metal noggings are also available, typically made from aluminium or steel. Metal noggings are more durable than wood noggings but are also more expensive.
Other less common noggings are -plastic noggings
kingpost
A kingpost uses a central horizontal post to support the upper members of the trust, it is usually located at the apex of the truss, and the other members radiate out from the kingpost. It provides strong and stable support and finds common use in structures requiring the bearing of heavy loads.
One of the main drawbacks of a roof kingpost is that it is unsuitable for all types of roofs.
