When it comes to constructing or replacing a roof, you may come across the term “roof trusses.” But what exactly are they, and why are they important?
This article will walk you through everything you need to know about roof trusses, including:
- What roof trusses are and their role in a home
- 7 common types of roof trusses homeowners should know
- How to choose the right roof trusses for your home
🤔 What Are Roof Trusses?

Roof trusses are pre-fabricated structures made of wood or metal, designed to support the weight of the roof and transfer it safely to the walls of the house. They consist of interconnected beams arranged in triangular shapes, which provide stability and distribute the roof’s load evenly.
Benefits of Roof Trusses for Homeowners
If you’re considering building a new home or replacing your roof, here’s why roof trusses are a preferred option:
- Cost-Effective: Trusses are factory-made, reducing labor costs on-site and minimizing material wastage.
- Quick Installation: Their pre-fabricated nature makes them faster to install compared to traditional roof framing.
- Strength and Stability: Triangular configurations enhance load-bearing strength, ensuring a durable and stable roof.
- Design Flexibility: They can be customized to fit a variety of architectural styles and functional needs, such as adding attic space.
👉 7 Common Types of Roof Trusses

Choosing the right type of roof truss depends on your home’s architecture, structural requirements, and intended use. Roof trusses are essential components of any building, providing support and shape to your roof while ensuring it can bear the necessary loads. Here are 7 popular types of roof trusses every homeowner should know:
1. King Post Truss
The king post truss is the simplest and most economical option, making it a popular choice for small- to medium-sized homes. It features a single vertical post (the “king post”) at the center, which connects the apex of the roof to the base. This design provides sufficient support for short spans, typically up to 16 feet. King post trusses are easy to construct, lightweight, and budget-friendly, making them ideal for garages, sheds, or modest residential spaces. However, they may not be suitable for larger or more complex structures requiring a wider span.
2. Queen Post Truss
The queen post truss is a variation of the king post truss, but with two vertical central posts instead of one. This design allows for a wider span, typically up to 30 feet, making it suitable for larger rooms, open floor plans, or hallways where more space is needed. The queen post truss is often used in constructions requiring a balance between strength and aesthetic appeal, as it creates a symmetrical, visually appealing structure. Its design also allows for better weight distribution, making it more versatile for different architectural styles.
3. Fink Truss
The fink truss is one of the most commonly used truss types in residential construction due to its affordability, strength, and efficient load distribution. Its distinctive “W” shape provides excellent structural support while using minimal materials, making it cost-effective. Fink trusses are particularly suitable for roofs with moderate pitches and are ideal for homes with standard roof designs. They can withstand heavy loads, such as snow or wind, making them a reliable choice in areas prone to harsh weather conditions. Their practicality and durability have made them a staple in modern homebuilding.
4. Scissor Truss
The scissor truss is specifically designed for homes with vaulted or cathedral ceilings. Its unique design features sloped bottom chords that create an open, airy interior space while still providing strong structural support. Scissor trusses are ideal for homeowners who want a dramatic ceiling effect without compromising stability. They are commonly used in living rooms, dining areas, or other spaces where a sense of openness and height is desired. However, scissor trusses require precise engineering and may be more expensive than standard truss options due to their complexity.
5. Attic Truss
The attic truss is a smart choice for homeowners looking to maximize roof space. Unlike traditional trusses, the attic truss incorporates a room within its design, allowing for additional attic storage or even a livable space. It’s an excellent option for creating extra bedrooms, offices, or storage areas without expanding the footprint of your home. Attic trusses are especially useful in houses with steep roof pitches, as they provide ample headroom and usable floor area. While they are more expensive and challenging to install compared to simpler trusses, the added functionality they offer makes them a valuable investment.
6. Gambrel Truss
The gambrel truss is recognizable by its barn-style roof design, featuring steep sides and a gently sloped upper section. This type of truss provides more headroom than other designs, making it ideal for attics, storage spaces, or even full second-story living areas. Gambrel trusses are commonly used in barns, farmhouses, and rustic-style homes due to their aesthetic charm and practicality. They are also highly versatile, offering excellent drainage for rain and snow while maximizing usable space within the roof. However, they require careful planning and installation to ensure proper weight distribution.
7. Flat Truss
Flat trusses are the go-to choice for homes with a modern, minimalist aesthetic. Unlike other trusses, they do not create a sloped roof, making them ideal for flat or low-pitched roof designs. Despite their simple appearance, flat trusses offer remarkable strength and structural integrity, capable of supporting heavy loads, including HVAC systems or rooftop decks. They are often used in contemporary and industrial-style homes or commercial buildings. Flat trusses are customizable to accommodate specific design requirements, but they may require additional waterproofing measures to prevent pooling water on the roof surface.
⚖️ How to Choose the Right Roof Trusses for Your Home

Selecting the right roof truss is a crucial decision involving several factors. Here’s what to consider:
Purpose and Functionality
Do you need attic space or a vaulted ceiling? Consider the primary purpose of your roof design before selecting the truss style.
Home Design
The architectural style of your home will influence your choice of trusses. For instance, gambrel trusses complement rustic or traditional aesthetics, while flat trusses suit contemporary homes.
Load Requirements
Factors like the weight of roofing materials and local climate conditions (e.g., heavy snow) must be considered to ensure the truss provides adequate support.
Budget
Some truss types, like the king post truss, are more economical. Discuss your budget limitations with your roofing contractor.
