When it comes to the construction of a roof, one of the essential elements is the truss. The truss supports the roof; without it, the roof would collapse. It is typically made of wood but can also be made of steel or aluminum. The most common type of roof truss is the triangular truss, used mostly in residential construction. The triangular truss consists of two pieces that extend from the “wall plate” to a “ridge beam.”

Roof trusses are used because they are strong and stable and can be built to support a variety of different roof shapes. They are also relatively easy to construct, making them a popular choice for homebuilders and homebuyers.

Here, we discuss everything you should know about roof trusses and how a Roofing Company in Charleston, WV can help ensure your roof is built safe.

Types of Roof Trusses


King Post Truss

King post truss consists of two vertical posts and a horizontal beam. The top of the king post truss is called the king post. It is a vertical pole connecting to the ridge board and the upper chords of each triangle. This truss type is often used in small buildings, such as sheds and garages.

Queen Post Truss

Queen post truss has two vertical members called posts, and two horizontal members called beams. The beams are connected to the posts at the top and bottom with metal plates or brackets. The beams also have diagonal braces that connect them with each other. This type of truss is solid and can support a lot of weight. It is often used in barns.

Scissor Truss

Scissor trusses are often used in roofs because they are very strong and can span long distances without support. They are also relatively easy to construct, making them a good choice for home and commercial buildings.

One downside of scissor trusses is that they are not as aesthetically pleasing as some other types of trusses. However, this is often offset by the fact that they are much cheaper to build.

Gable Truss

A Gable truss has two sloping sides that come together at a peak, forming a triangle shape. Gable roof trusses are strong and stable, making them ideal for supporting heavy roofs. Gable roof trusses are made up of several rafters and joists. Each rafter is a straight piece that extends from the ridge beam to the end of the building.

Fink Truss

The Fink truss has two diagonal members that meet in the middle at a point called the apex. The apex is usually lower than the eaves, which gives the Fink truss its characteristic W-shape. The two diagonal members are connected by horizontal members called top chords. Horizontal members also connect the bottom chords but run opposite to the top chords.

Attic Truss

An attic truss is a roof truss designed to create additional storage space in the attic. While attic trusses are more expensive than traditional roof trusses, they can be a great way to add extra storage space to your home. Attic trusses are typically made with shallower slopes and shorter lengths than other roof trusses, allowing for more attic headroom.

Roof Truss Installation Explained

A roof truss is a structural frame that forms the roof of a building. It is composed of rafters, joists, and struts. Roof trusses are typically made from wood but can also be made from metal or other materials.

There are many types of roof trusses, but the most common type is the triangle truss. Triangle trusses are strong and stable and can support a heavy load. They are often used in commercial construction.

Installing a roof truss is not difficult, but it does require some planning and coordination. Most homeowners can complete the job in a few hours with the proper tools and instructions. The first step is to measure the area where the truss will be installed. Next, cut the lumber to size and assemble the truss using gussets and metal plates. Finally, install the sheathing and roofing materials. Once the truss is assembled, it can be lifted into place and secured to the rafters or joists. Here is how you should go about installing a new roof:

  • Figure out which type of truss is needed.
  • Fit the truss entirely before lifting it.
  • Attach the truss with the beams.
  • Don’t miss any spot; nail it carefully.
  • Make sure the truss is aligned at all times.

How to Tell if a Wall Is Load Bearing

Knowing whether or not a wall is load-bearing is essential when considering remodeling your home. This is important as it determines whether you should go for reroofing or roof replacement. Here are a few ways to tell if a wall is a load-bearing:

First, you’ll want to look at the framing of the house. If the house has stick framing, load-bearing walls are usually perpendicular to the floor joists. In platform framing, load-bearing walls are usually parallel to the floor joists.

Another way to tell if a wall is load-bearing is by looking at the weight of the materials that make up the wall. Heavier materials like brick or stone are more likely to be load-bearing. Lighter materials like drywall or plaster are less likely to be load-bearing.

Finally, you can also tell if a wall is load-bearing by its position concerning other structural elements in the house. Besides that, you should check out these five warning signs that you need a new roof.

Key Takeaways

A roof truss is a frame that supports the roof of a structure. The most common type of roof truss is the pitched roof truss, with a sloped surface that allows water and snow to run off. There are also flat roof trusses, which are commonly used in commercial buildings. Roof trusses can be made from wood, metal, or engineered lumber.

There are several benefits to using roof trusses in construction. Roof trusses are strong and durable and can support a heavy load. They are also easy to install and can be prefabricated off-site. This saves time and money during construction. Roof trusses are also versatile and can be designed to fit any shape or size of the roof.
