We can also offer free advice on ordering your trusses and can assist you fully with the process. Simply contact us to begin your enquiry. Also, check out our case studies for some of our recent projects.

The Advantages Of Trusses

The first thing you truly need to understand is just how many advantages there are to using roof trussesrather than rafters. Not only are they aesthetically pleasing, but they are also:

  • Up to 50 percent more cost-efficient than regular rafters.
  • Light and easy to produce quickly .
  • Simple to install in comparison to other roof elements.
  • Adjustable for future home and ceiling improvements.

Additionally, truss systems are great at distributing your roofs weight into the exterior walls, rather than the interior walls. This means that you can achieve a more open feel within your home something that is highly valued in todays home design trends.

Example Of Truss Costs Calculation

Here is an example to give you a clearer idea of how project costs are calculated. Suppose a customer needs trusses for a private house with a roof area of 12.6m x 9m with a metal tile roofing.

1. Creating building geometry. In this step, the geometry of the building is created based on the parameters of the clients project.

2. Creation of the roof plane. Based on customer information and the project design analysis, our engineer determines the height of the roof and the slope of the roof.

3. Truss creation. Once the roof plane has been drawn, the trusses themselves must be created. Trusses are made based on several factors:

  • Weight of roofing.

4. Truss placement in the roof plane. Based on the design parameters and the roof plane, the timber trusses are positioned to support the entire roof area.

5. Calculation of the offer. Because this project has a very simple solution, you only need to produce one truss variant, but sometimes there are projects that use more than 50 truss types. All in all, we see that this project requires the manufacture of 9 trusses, 2 rafters and the addition of mounting parts . Total cost of the project with delivery and VAT is 1427,16 EUR.

Another thing you should be aware of is that several roof trusses can be practical for weather in certain areas, yet may not accommodate the buildings desired design specifications. Good engineers and architects will also consider the design of the building.

How To Use The Roof Truss Calculator

How to Build Wooden Roof Trusses

Our tool has two applications. You can use it either as a rafter length calculator, and get the dimensions of your trusses estimated, or as a roof truss count calculator, which will also allow you to estimate the roof truss costs and even include the price of installation.

To start your calculations, you need to choose from the two options mentioned above. In the field above the illustration, pick either “rafter length” or “truss count”.

  • If you picked rafter length:
  • Start by deciding what you want your calculations to be based on. You can choose the rise of the roof , or the roof pitch . If you want to learn more about the way it’s calculated, check out our roof pitch calculator.

  • If you picked truss count:
    • Input the roof length, the on-center spacing , and the roof truss calculator will return the number of roof trusses needed.

    • Our tool can also figure out the approximate roof truss cost. In the next fields of the calculator, decide whether you want to include the costs of installation in the calculations.

    • If you pick no, the only thing left to input is the cost of a single roof truss. The roof truss calculator will return the total expenses in the bottom-most field.

    • If you pick yes, you will also need to declare how much per time unit would the contractor installing the trusses charge you, as well as the expected duration of the installation. As soon as you fill in all the variables, you will see the total expenses at the bottom of the calculator.

    How To Install Roof Trusses

    By: Author Ryan M.

    A roof truss is a structural framing system that supports the weight of the roof on top of a building. They are typically used in houses, barns, and other agricultural buildings.

  • Main Benefits of Roof Trusses
  • The roof trusses are assembled together to form an open space inside the house for your attic or loft area. Installing them can be difficult if you dont have any prior experience with construction projects.

    Its important to know what type of materials you need before starting construction, as well as how to cut boards, measure angles, and attach joints correctly.

    How Much Does It Cost To Install Trusses

    The average cost to install trusses is $5-$12 per square foot, with the average homeowner spending around $9,000 on installing trusses for their home. Trusses are a necessary component of any home with a pitched roof, and their installation costs will vary depending on the size and complexity of the roof.

    The Main Details For Quotes Or Orders:

    To start the process of either getting a quote or placing an order, there are some important details that we will need. Providing us with a floor and or roof plan is the best way, if possible. That helps ensure that we both will be building to the same dimensions and plan. Of course, the more complicated the project, the more details will be needed to design but here are the basic ones that cover most of it:

    • Full Customer Name and Business Name
    • Phone Number and Email Address
    • Location of Project
    • Overhang, Tail, or Soffit Width
    • Loading / Roof and Ceiling Material

    The Easiest Way To Calculate Your Roof Truss

    Simple Explanation About Roof Truss Design, Parts And Assembly

    When its time to replace your roof, the contractor isnt the only one that has work to do. If youre in the market for roof replacement, youll have to take the time out to educate yourself on a few different roofing components and their dimensions.Having this knowledge will help you determine where your money is going when you receive a cost estimate from the contractor you choose to work with. One example of a roofing part youll need to measure is a roof truss. A roof truss is typically a triangular structure that is designed to distribute the weight of the roof. The two parts of a roof truss and the members and the intersections that disperse the weight evenly down the length of each member. The truss is built by attaching the ends of the member to joints that connect to the intersections.

    Learning how to estimate roof trusses and their measurements may seem like a tough problem but we put together a formula to help you easily figure out your roof truss calculations. The simplest and most easy to build roofs are usually Open Gable Roofs, and this is the type of roof that most homeowners have. To calculate the measurements of this type of roof truss, its best to use the Pythagorean Theorem. This old equation that you may remember from middle school will finally come in handy to help you during your roof replacement journey. We chose this equation because it allows you to reduce each truss to a pair of right angles triangles that are arranged back to back.

    Options For Ordering Trusses

  • Type – What type of truss do you want on the building? Common gable truss, hip, gambrel, bowstring, scissor, and etc.
  • Number – How many of each type of truss are needed for this particular building.
  • Span – Distance between outside walls or bearing points where the trusses will be placed.
  • Pitch – What will the pitch of the roof be 6/12, 8/12, etc.
  • Height Above Plate – What is the desired heel height above the wall plates at the outside edge of the building? Would you rather used a raised heel truss to accommodate more insulation?
  • Load – What are the required live, dead, and wind speed load requirements in your area? These questions can be answered by your local building inspector.
  • Bearing Width – How wide are the bearing walls or beams where the roof trusses are to sit?
  • Ceiling Type – What type of ceiling is required in each room? Cathedral, vaulted, barrel, etc.
  • Build Your Own Roof Trusses

    The very first step for building roof trusses is to prepare a design layout that can be sketched by a professional architect or can also be done by using a software that is specifically meant to design a roof truss.

    The second step in building a roof truss is to prepare the materials needed. These will include wood, a hammer, a saw, roof truss plates made from galvanized steel and galvanized screws of 1 ½ inches.

    The wood needs to be cut based on the size of the roof and specifications in the design. It must also adhere to all the local building standards and codes. Most of the time, the sizes of the wood used range from 2Ã6 and 2Ã8 even though its thickness can be based on the weight that it will support and the overall size of the roof.

    It is crucial that you use connector plates made from galvanized steel. It is a kind of steel that has a zinc coating and can prevent the occurrence of any corrosion.

    The plates and the wood will join together in the shape of a triangle and will then be fastened together using galvanized steel screws, which arent shorter than 1 ½ inches in their length. Depending on the woods thickness, you might also want to use thicker screws.

    If you want to build a roof truss with the use of other materials aside from wood, like steel, aluminum or tin, you will need to cut the material based also on the roof size and design specifications, just like with wood trusses.

  • What Is A Roof Truss

    Roof Design, Roof Trusses, Tiles, Sheeting, Installations

    Essentially, roof trusses create a roofs frame. They determine the shape of the roof and ceiling while providing support for the roof. Trusses are pre-engineered in a factory using lightweight materials, like 2x4s, and are shipped to the construction site. Trusses consist of three main parts:

    Bottom chords


    Trusses are used as an alternative to rafters, or stick framing. Rafters are usually made from larger pieces of lumber, such as 2x8s or 2x10s, and require the skill of an expert carpenter to custom-build and install them directly on the job site.

    This makes rafters more expensive than trusses.

    How To Build Roof Trusses For A Garage

    If you want to know how to build roof trusses for a garage, you must ask a professional about the right support of the roof as well as its weight.

    Trusses are utilized for stabilizing and supporting the walls, particularly in huge buildings that have more than one to two stories.

    Usually, roof trusses are triangular and can be installed easily. Another advantage of roof trusses for a garage roof is that they are practical and can be used with several materials.

    Learning how to install roof trusses for a garage roof isnt hard, particular if you follow particular hints and tips.

    • Cutting the Timbers

    The first thing you should do when building roof trusses is to cut timber panels to the garage roofs size. Measure the roofs span and check with the building project and plan.

    Before you buy timber panels, you must also take into consideration the weight theyll be supporting. The reason behind it is that this will help you know their thickness. More often than not, you will have to purchase 2×8 timber panels and cut them to the size if required.

    • Securing Timber Panels Together

    Utilize the connector plates when securing timber panels and creating a triangular shape. For securing the panels and maintaining the triangular shape, use screws.

    • Adding the Brace
    • Securing the Trusses

    When attaching roof trusses to roof frame, make use of deck screws. The majority of professionals would suggest or recommend you to brace trusses.

    • Extra Tips to Remember

    Do Roof Trusses Need Support In The Middle

    Constructability3D – Identifying Roof Truss Issues BEFORE Ordering!

    No, roof trusses do not need support in the middle. Trusses are designed to bear only on outer walls. Whether your home has 2×4 or 2×6 framed walls, a roof truss does not need interior support provided the distance between bearing walls the span aligns with the span rating of the truss.

    Some contractors will order undersized trusses to save money. For instance, a contractor may need a truss for a 30 span, but order trusses that are 30 but underbuilt with a smaller dimension of lumber or just less lumber. In these cases, an interior wall is needed to support the underbuilt truss.

    Therefore if you have a home with trusses, you cannot automatically assume you can remove all your interior walls without detriment to your home. It is always critical to consult with a building engineer before removing interior walls, even if you have roof trusses.

    Can You Convert A Trussed Roof

    A trussed roof is a roof that is constructed with pre-fabricated metal or wooden trusses. These trusses are designed to support the roofing material and distribute the weight of the roof evenly. It is not possible to convert a trussed roof into a conventional roof. If you need a conventional roof, you will need to remove the trusses and replace them with rafters.

    Building Plans Layouts Or Sketches Are Highly Recommended

    Building to a drawn out plan is a good practice. If you dont have a plan on paper or PDF, I would highly recommend drawing one or getting one drawn if we are talking about any residential work.

    An agricultural barn is a different story and doesnt require a plan for trusses very often but having a plan is always the best course of action.

    We can make it work without a plan as long as we both can understand over the phone or by email what it is that you need. Remember that a phone connection is not always the best and letters and numbers can sound alike at times.

    In the case of a project that is an easy rectangle shape with a simple gable or hip roof, there isnt too much that can go wrong as long as the dimensions we hear over the phone are correct. If a project goes beyond a simple shape, it can be difficult to explain over the phone in a way that is correct and all parties involved understand.

    At that point, it would be a good idea to sketch it out on a piece of paper and email it to us if you dont have a floor and/or roof plan. The sketch can be as simple as hand drawing it on a piece of paper. The dimensions of the walls need to be to the outside edge of supporting or framed walls and not include brick, sheeting, Styrofoam or things like that. If the measurements do include all this, thats okay as long as we know that and know how much to account for it. This is important as it will affect the truss design especially if the trusses have cathedral.
