What Is A Truss?

Before everything, let’s first begin with a piece of brief information on what a truss is and every other detail of it. It will help you to identify and learn more about trusses.

A truss is a triangulated system of constructed and attached components so that only axial pressure is applied. In contrast, the members are classified into two because the forces are delivered only at one end of the member, resulting in compression or tension. Bridge design uses its capability to be cost-effective and cover long distances.

Joints are sometimes trapped, preventing shear and moment stresses from being transferred. The fact that it is often misunderstood makes the difference between truss and frame structures vital. A frame member typically bears shear, axial, and bending forces, whereas a truss member bears solely axial force.

Another thing to know about trusses is that it also has its benefits. Here are its advantages:

  • Trusses are a cost-effective way to span long distances while using the least amount of material possible.
  • Internal loads of the members are induced axially (in the member’s direction) in the form of compression or tension, and this is the case. Because it distributes the force among several members, you can use less material, and the system as a whole is more efficient.

There are different types of trusses and their uses. Below are the lists of some:

Many components make up a roof truss. Chords are the external frame components, and webs are the inside triangle structures.

Two different size and shape options are available depending on the job’s demands. The king post is vertical support that helps maintain structural integrity in roof trusses that include them.


King post truss

It is a type of truss for short spans. Moreover, extensions, garages, porches, and sheds are all common uses for them. Many historic structures have open, visible king post trusses.


Queen post truss

It is a type of truss that supports vertical upright with two triangles on either side that makes up a queen post truss. These are no longer regularly utilized, as the Fink truss has taken their place.


Fink truss

A fink truss has a ‘W’ form between the chords and is a frequent roof truss type. It’s a simple but effective shape that you may apply to a variety of tasks.


Double pitch profile truss

The double pitch profile truss is commonly employed in commercial structures, although some dwellings can also find it.


Truss with a single pitch

A mono-pitch truss is a right-angle truss with a single rafter that creates lean-to roofs or single-pitched roofs.


Scissor truss or vaulted truss 

You can use a scissor truss to produce vaulted ceilings or other unusual ceiling designs.


Tie truss with raised tie

Vaulted ceilings are made with raised tie trusses. You can lift the lower chord to give a flatter appearance for higher tops with diagonal edges.


How To Fix Water Damaged Trusses

Step #1. The first step is to repair the roof leak and then use a small screwdriver to check the roof truss for wood deterioration such as termites or wood rot.

Step #2. Suppose the screwdriver goes deeper than a quarter of an inch into the roof truss water damaged region without pressing too hard. In that case, it’s a good idea to contact a local professional for a more accurate assessment of the damage.

Step #3. Brace or support the truss temporarily to prevent further damage to the truss and worker hazard.

Step #4. Immediately notify the truss manufacturer of any damage, changes, or installation mistakes.

Step #5. Do not attempt to repair the truss unless the Building Designer, Truss Designer, or Truss Manufacturer has provided a Repair Detail.

Step #6. Lay the truss flat on a sturdy, level surface before beginning the repair. If the truss is already in place, reinforce it to relieve the load.

Step #7. Repair the truss by carefully following the instructions in the Repair Detail. Make sure you’re using the right supplies for the job. If something isn’t clear, it is best to get professional help.



These are the information that could best help in aiding you on how to repair water damaged trusses. Ideally, it is essential to know first what case you are handling. It is why we first gave some detail and information to get to know about the truss.

It will help you in terms of appropriateness in using the right tools and steps to follow. However, if things get complicated and become too difficult for you to handle because of severe water damage on your truss, don’t hold back to seek professional help. Make sure to follow the steps, and read the details carefully.
