Constructing A Shop With Chicken House Trusses: Diy Guide

Chicken house trusses are a popular choice for those looking to build a shop or barn on a budget. They are often sourced from dismantled chicken houses and can be purchased second-hand for a low price. When building with chicken house trusses, it is important to consider the height of the structure, as the trusses are typically placed further apart, resulting in a higher ceiling. This can be advantageous for those seeking a taller building. However, it is crucial to inspect and clean the trusses thoroughly before use, as they may be contaminated with bird viruses or show signs of decay from moisture exposure. To ensure the safety and longevity of the structure, proper roofing materials, such as metal sheets, should be used to protect the trusses from harsh weather conditions and pest infestations.

Truss design and materials: Choose between wooden or steel trusses, considering budget and maintenance

When it comes to truss design and materials, you have the option of choosing between wooden or steel trusses. There are several factors to consider when making this decision, especially regarding your budget and the required maintenance of the trusses.

Wooden trusses are generally cheaper than steel trusses, which makes them a more economical choice for construction. However, they do not last as long as steel trusses. Timber, being a natural material, is susceptible to warping, bowing, and distortion over time due to exposure to moisture or humidity. This can lead to structural damage and costly repairs. Additionally, wood is prone to rot, insect infestations, and severe weather damage. Wooden trusses require heavy timber support and a webbing design that fills the area below the roofline, reducing overhead clearance.

On the other hand, steel trusses are designed to last a lifetime. They are coated with a protective finish to prevent rusting and are highly durable due to their engineered robotic welds. Steel trusses offer better overhead clearance as they do not require the same extent of supporting infrastructure as wooden trusses. They can be spaced up to 10-12 feet apart, sitting directly on the building posts, which reduces the number of trusses needed and saves on material and labour costs. The steel market is also more predictable and stable in terms of pricing when compared to the volatile lumber market.

While steel trusses may have a higher price point per truss, the total cost of a project using steel trusses can be lower due to the reduced number of trusses needed and the associated labour savings. Steel trusses are also low maintenance, requiring very little ongoing upkeep and no chemical treatments to maintain their integrity. They are fire-resistant, insect-proof, and not susceptible to issues like mould, rot, or moisture damage.

When deciding between wooden and steel trusses, it is essential to consider your budget, the time you want to invest in maintenance, and the potential long-term savings associated with each option.

Truss spacing: Determine the optimal distance between trusses to ensure adequate support

Truss spacing is an important consideration when building a shop with chicken house trusses. Optimal truss spacing will ensure that your structure is safe, stable, and able to withstand loads such as heavy snow and ice.

Chicken house trusses are typically set on 5-foot spans, which means they are designed to hold a heavier load than a standard truss. However, it's important to note that the truss spacing can vary depending on the specific requirements and dimensions of your shop.

When determining the optimal distance between trusses, you should consider the length, width, and height of your shop. For example, if you have a longer or wider shop, you may need to use a closer truss spacing to provide adequate support. Additionally, if you prefer a taller ceiling, you will need to space your trusses further apart, which will require more trusses overall.

In general, it is recommended to space chicken house trusses 10 feet apart from centre to centre. This spacing can be adjusted slightly depending on your specific needs. For instance, if you have a large clear span, you may need to reduce the truss spacing to provide sufficient lateral bracing for your beam. In this case, a 6-foot truss spacing might be more suitable.

It's important to consult with a structural engineer or a professional with experience in building shops with chicken house trusses. They can help you calculate the precise truss spacing required for your shop's dimensions and ensure that your structure is safe and compliant with local building codes.

Roof design: Decide on the roof shape and materials, considering factors such as overhangs and weight

When building a shop with chicken house trusses, it is important to carefully consider the roof design, including the shape and materials used. The roof is a crucial component of a building's aesthetics and functionality, impacting energy efficiency, structural integrity, and architectural style. Here are some factors to consider when deciding on the roof shape and materials:

Roof Shape:

• Gable Roof: A gable roof, also known as a peaked or pitched roof, is one of the most common roofing types worldwide. It has a triangular or inverted "V" shape, making it easy to identify. Gable roofs offer several advantages, including effective water and snow shedding, improved attic ventilation, and lower construction and maintenance costs compared to other roofing types. They can be covered with various materials, such as asphalt shingles, slate, concrete tiles, or metal. However, gable roofs are prone to storm damage, especially with significant overhangs.
• Mansard Roof: A mansard roof is a hallmark of French design, featuring a dual-pitched structure on all sides. The steeper lower slope creates usable attic space, often converted into living areas. This style offers design versatility for windows and ornamental features. However, it demands precise craftsmanship and materials, increasing construction costs.
• Flat Roof: Flat roofs are commonly used in commercial buildings and modern homes. While they appear flat, they have a slight incline to prevent water collection. Flat roofs provide a versatile surface for rooftop gardens, solar panels, or outdoor living spaces. However, they require meticulous waterproofing to prevent leaks and need regular maintenance to check for pooling water and debris.

Roof Materials:

• Metal Roofing: Metal roofing is durable, weather-resistant, and long-lasting. It has been used extensively in houses, farm structures, and commercial buildings. Metal roofing panels can be installed directly over worn-out older roofs, simplifying the installation process. Metal roofs are not suitable for complex or curved roofs.
• Clay and Concrete Tiles: These materials offer thermal insulation and fire resistance while helping regulate indoor temperatures. Clay tiles are commonly used in Mediterranean and Spanish-style homes, while concrete tiles provide a broader range of styles and colours. They are more expensive and require sturdy support but can offset the initial investment with their long lifespan and minimal maintenance.
• Solar Shingles and Roofing: Solar shingles and roofing tiles integrate photovoltaic technology, helping to increase the energy efficiency of your home. ENERGY STAR®-rated shingles can lower roof surface temperatures significantly.

When deciding on the roof shape and materials, it is essential to consider factors such as overhangs, weight, environmental conditions, and the intended use of the building. Overhangs, for example, can impact the building's aesthetics and its vulnerability to storm damage. The weight of the roofing materials, including shingles, insulation, and structural components, must be precisely calculated during the design phase to ensure adequate support. Additionally, environmental factors like snow loads in colder climates or wind loads in windy regions will influence the design and material selection to ensure the roof's structural integrity.

Truss preservation: Protect trusses from pests, moisture, and harsh weather conditions to ensure longevity

Chicken house trusses can be a great option for building a shop, as they offer a cost-effective way to achieve a spacious structure. However, it is important to ensure the longevity of your shop by preserving the trusses. Here are some detailed, direct, and instructive guidelines to protect your trusses from pests, moisture, and harsh weather conditions:

Pest Control

Pests, such as wood beetles, carpenter ants, and termites, can cause significant damage to wooden structures. To prevent pest infestations, consider using wood that is naturally resistant to pests, such as cedar or teak. Regular inspections by a professional pest control company are crucial to identify and address any pest issues promptly. Additionally, you can treat raw wood with spray products designed to protect against pests.

Moisture Management

Excess moisture can lead to the growth of fungus and mould on the trusses, compromising their integrity. To prevent moisture-related issues, ensure proper ventilation during storage and cover the trusses with tarpaulins to protect them from the elements. When installing the trusses, follow correct installation practices to minimise the risk of uneven rooflines, which can be caused by incorrect installation rather than moisture content.

Weather Protection

Harsh weather conditions, including variations in temperature, humidity, rain, and snow, can take a toll on wooden trusses. To protect your trusses from the weather, consider applying a protective layer such as paint, stain, or sealant. Among these options, stains and sealants are particularly effective as they penetrate the pores of the wood, making it water-repellent. If your trusses are already showing signs of weather damage, pressure washing can help restore them, but it is recommended to hire professionals for this task.

Storage and Installation Considerations

Proper storage and installation practices are crucial for truss preservation. When storing trusses horizontally, use blocking to minimise lateral bending and moisture gain. During long-term storage, ensure the trusses are protected from the environment and covered to prevent moisture gain. When installing the trusses, spacing them further apart can reduce the number of trusses needed while still providing the required structural support.

By following these guidelines, you can effectively protect your chicken house trusses from pests, moisture, and harsh weather conditions, ensuring the longevity of your newly built shop.

Truss sourcing: Source trusses from a manufacturer, repurpose used ones, or build them yourself with the right tools

Chicken house trusses are an essential component when building a shop or barn. There are several options for sourcing these trusses:

Sourcing from a manufacturer

You can source chicken house trusses from a manufacturer. This option may be more expensive, but it ensures that the trusses are built to your exact specifications and can be customised to your needs. This route may be preferable if you are particular about the dimensions of your shop and want to avoid the potential complications of using second-hand trusses.

Repurposing used trusses

Another option is to repurpose used chicken house trusses. These can be sourced from local commercial chicken farms, and they offer the advantage of potentially reducing costs. For example, one individual reported that they acquired used trusses for $30 per piece, which was significantly cheaper than buying new ones. However, it is important to consider the potential drawbacks of this option. Used trusses may require additional cleaning and inspection to ensure they are safe and free from any bird viruses or odours. There is also a risk of structural issues, as some chicken houses have collapsed due to heavy snow and ice loads in the past.

Building them yourself

Finally, if you have the necessary skills, time, and equipment, you can attempt to build the chicken house trusses yourself. This option provides you with complete control over the design and construction process, allowing you to customise the trusses to your specific needs. However, it is important to consider the time and resource investment required for this option, and whether your skills can produce professional-level results.

Each option has its advantages and considerations. When deciding on truss sourcing, it is essential to evaluate your budget, time constraints, skill level, and the specific requirements of your shop-building project.
