If you’re buying a home and would like to know how to build a 4 12 pitch roof truss, it’s easy to find a handful of householders calling themselves expert carpenters that will happily show you exactly how they built their own. These guys are often fantastic people, but if you are counting on them for an answer, then you should also be aware of the fact that most probably have not designed and installed a 4 12 pitch roof truss at a residential home under any certification program.
How to build a 4 12 pitch roof truss
Roof trusses are an essential component of a roof system. They are the skeleton that supports your roof and allows it to span great distances.

How to Build a 24′ x 36′ 4/12 Pitch Roof Truss / Purlins
24 foot 4/12 pitch truss is the most common one used for residential construction projects, it is also called 12/12 pitch or even 6/12 pitch sometimes because of how many inches of rise per foot of run there is on the rafters. If you want to build this type of truss yourself then you need to first understand how they work and what materials do they require to be built properly. This article will cover everything you need to know about these types of roof trusses, including how they work and what materials do they require to be built properly.
If you are looking for a home truss design, you will find that there are many different options. The most popular option is the 4/12 pitch roof trusses. These types of trusses are used on most homes and they can be purchased in many different sizes to fit your needs.
Build a 4/12 Pitch Truss
I am going to show you how you can build a 4/12 pitch truss that is 24 feet long and 30 feet long. You will need some basic tools to complete this project such as a circular saw, hammer, screwdriver, and tape measure.
I have included some additional information about the materials that you will need for this project along with some pictures below:
Materials Needed:
1 sheet of plywood per truss (for example: if building 2 trusses then 2 sheets of plywood)
8 pieces of 2x4s per truss (for example: if building 2 trusses then 16 pieces).
Building a 4 12 Roof Truss
Building a simple roof truss is not only easy, but it can be done in just a few hours. The right tools and materials are needed, of course. If you want to build your own roof trusses, the first thing you need to know is what size they should be. This will vary depending on the size of your house and how much weight it has to support.
Be sure to check your local building code as well; some codes may require certain sizes or calculations for safety reasons.
The general rule of thumb is that each side of a truss needs to be at least 24 feet long and have an angle of 60 degrees or more between each set of supports (known as rafters). The depth (or height) of the truss should be at least 8 feet tall in order for it to support enough weight without bending or breaking under pressure from snow and wind loads.
Building a 4 12 pitch roof truss is a fairly simple process. The first thing you will need to do is measure the width of your building and divide it by 12. This will give you the pitch for your roof. For example, if your building is 24 feet wide, then your roof pitch will be 2/12 (or 2 inches of rise for every foot of run).
The next step is to decide how high above the ridge of the roof you want to install your trusses (this will also determine how long they are). You can make this measurement by standing on an 8 foot ladder at one end of your building (where the peak will be) and holding up a straightedge at eye level. Mark where it touches the wall or ceiling below it, then measure back along that line until it intersects with where your other straightedge touches the opposite wall or ceiling below it. Multiply this number by 3 to get the height of each truss above its bottom chord (you may want to round up or down slightly here). Add these numbers together and divide by 5; this is how many trusses you will need (usually 10)
Roof trusses are one of the most popular and cost-effective ways to build a roof. They’re easy to design, easy to build and virtually indestructible.
Trusses are typically made from timber or steel, and there are two main types:
Simple trusses are made from one piece of timber, usually square or rectangular in shape, with webbing attached at each end.
Compound trusses have more than one piece of timber in the construction of the truss. They may also have different sizes and shapes of timber used in their construction.

The 30 foot 4/12 truss dimensions refers to the width and height of the trusses in inches (feet). For example, a 30×20 would refer to a 20′ wide by 30′ tall truss.
Truss spacing depends on the building’s span length. For example, if you have an 18′ wide span then each set of trusses should be spaced 18″ apart from one another (measured from centerlines).

If you’re looking to build a new house or garage, then you’ll need to know how to find out the size of the trusses that you’ll need. The following information will help you determine the length and width of your trusses.
The first thing that you need to do is determine what type of roof you want. This will help determine the size of the trusses that you will need. There are three basic types of roofs: gable, hip and flat roofs.
To find out how big your trusses will be, simply follow these steps:
For Gable Roofs:
Measure from peak to peak and multiply by 3.14 (pi). The result is your peak span for each side of your house. Then measure from ridge-to-ridge and multiply by 3.14 again for an overall height for your roof. The result is your ridge span for both sides of the house added together; this will give you an approximate total height for both sides of your home if it has a gable roof design.
For Hip Roofs:
Measure from peak to peak at each end of the ridge line, then add those two numbers together; multiply by 3
A truss is a structural frame used to span a large distance between supports. Truss may be made of materials such as timber, steel and iron. A network of criss-crossed timbers can be used to build the frame of a house.
A truss is similar to a beam or girder, but unlike the traditional beam, the truss has its members (pieces) arranged in compression and tension. In other words, the members are primarily in compression and only secondarily in tension. The diagonal members are called braces or struts. The amount of tensioning forces in these members is controlled by their lengths and the number of joints between them.
The trusses are typically made from lightweight material such as wood, aluminum or steel so that they can be easily transported and assembled on site without heavy machinery.
