What Is The Name Of The Wood That Holds Up The Roof?

Have you ever wondered what the key component is that keeps your roof from collapsing? Well, look no further because in this article, we will explore the answer to this age-old question: What is the name of the wood that holds up the roof? We will dive into the world of structural support, uncovering the various types of wood used in roofing, and discover the importance of choosing the right material for a durable and secure roof. So, get ready to expand your knowledge and gain a deeper understanding of the crucial role that wood plays in holding up the roof above your head.

The Importance of Roof Support

Ensuring Structural Integrity

When it comes to constructing a building, one of the most crucial elements to consider is roof support. The wood used in roof support plays a significant role in ensuring the structural integrity of the entire building. Without adequate support, the roof could sag or even collapse, posing serious risks to the safety and stability of the structure.

Providing Weight Distribution

Roof support not only helps to maintain the integrity of the building but also plays a vital role in distributing the weight of the roof evenly across the entire structure. By properly distributing the weight, roof support helps prevent any undue stress on specific areas, which could lead to structural damage over time. With the right type of wood for roof support, you can ensure that your building withstands the test of time.

Protecting Against Natural Elements

Another important function of roof support is protecting the building from the natural elements. The wood used in roof support must be able to withstand the forces of wind, rain, snow, and even earthquakes. A sturdy and reliable roof support system will help keep your building safe and secure during extreme weather conditions, ensuring the longevity of the structure and the safety of its occupants.

Types of Wood Used for Roof Support

Common Softwood Species

  1. Pine: Pine is a popular choice for roof support due to its affordability and availability. It is lightweight yet strong enough to provide adequate support for most residential roofs.
  2. Spruce: Spruce is another common softwood species used for roof support. It offers a good balance of strength and affordability, making it a popular choice for both residential and commercial buildings.
  3. Fir: Fir wood is known for its excellent strength-to-weight ratio, making it an ideal choice for roof support systems. It is resistant to decay and can withstand heavy loads, ensuring the structural stability of the building.

Engineered Wood Products

  1. Plywood: Plywood is a versatile and cost-effective option for roof support. It is made by bonding layers of thin wood veneers together, creating a strong and durable material. Plywood is commonly used in residential and commercial construction due to its strength, versatility, and availability.
  2. Oriented Strand Board (OSB): OSB is an engineered wood product made by compressing and gluing together strands of wood chips. It is an affordable alternative to plywood and offers similar strength and stability. OSB is widely used for roof support in both new construction and remodeling projects.
  3. Glulam (Glued Laminated Timber): Glulam is made by bonding layers of dimensioned lumber together with strong adhesives. This results in a material that is stronger and more durable than traditional solid wood. Glulam is commonly used in roof support systems where long spans or curved shapes are required.

Traditional Hardwood Species

  1. Oak: Oak is a hardwood species known for its strength and durability. It is commonly used in roof support systems where exceptional load-bearing capacity is required. Oak is a premium wood option and is often chosen for its aesthetic appeal as well.
  2. Beech: Beech wood offers good strength and resistance to decay, making it suitable for roof support. It is not as widely used as other hardwood species but can still be a viable option depending on availability and cost factors.
  3. Maple: Maple is another hardwood species commonly used for roof support. It is known for its strength and stability, providing a reliable and long-lasting option for structural support.

Factors to Consider When Choosing Roof Support Wood

Load-Bearing Capacity

The load-bearing capacity of the wood is one of the most crucial factors to consider when choosing roof support materials. The wood must be able to withstand the weight of the roof without sagging or failing. Different wood species have varying load-bearing capacities, so it’s essential to select a type of wood that can adequately support the specific roof structure and any potential loads it may encounter.

Resistance to Moisture and Decay

Roof support wood is constantly exposed to moisture, whether it’s from rain, snow, or humidity. It is vital to choose a wood species that has natural resistance to moisture and decay, or to treat the wood with preservatives to enhance its durability. By selecting a moisture-resistant wood, you can prevent rot, decay, and other forms of damage caused by water infiltration, thus extending the lifespan of your roof support system.

Cost and Availability

Cost and availability are practical considerations when choosing roof support wood. Some hardwood species may be more expensive or challenging to source, while softwood species are generally more readily available and affordable. It is essential to strike a balance between cost, availability, and the desired properties of the wood to ensure a cost-effective and practical choice for your roof support system.


In conclusion, roof support plays a critical role in maintaining the structural integrity, weight distribution, and protection against natural elements of a building. The choice of wood for roof support should be carefully considered, taking into account factors such as load-bearing capacity, resistance to moisture and decay, cost, and availability. By selecting the right type of wood for your roof support system, you can ensure the longevity and stability of your building, providing a safe and secure environment for its occupants for years to come.
