by | Jul 15, 2023 | Blog | 0 comments

Selecting the suitable decking material for a sturdy and long-lasting roof is crucial to ensure the overall durability and performance of the structure. The choice of decking material significantly impacts the roof’s strength, longevity, and maintenance requirements. This article will explore various decking materials, discuss their pros and cons, and provide insights into the factors to consider when selecting.

Different Decking Materials Explained

1. Wood Decking

Wood is a popular choice for decking due to its natural beauty and versatility. Common types of wood used for decking include cedar, redwood, and tropical hardwoods like ipe. Wood decking offers a classic and traditional appearance, blending well with various architectural styles. However, it requires regular maintenance, including staining and sealing, to protect it from rot, insects, and weather damage.

2. Composite Decking

Composite decking is a blend of wood fibers and recycled plastic. This material offers a low-maintenance alternative to traditional wood decking. Composite boards resist rot, insects, and fading and do not require staining or sealing. They are available in various colors and styles, providing homeowners with design flexibility. However, composite decking can be more expensive than wood, and some lower-quality products may be prone to fading or scratching.

3. Metal Decking

Metal decking, such as steel or aluminum, is known for its durability and strength. It offers excellent resistance to fire, rot, and insects. Metal decking is lightweight, making it easier to install and reducing the load on the structure. It is particularly suitable for areas with high wind or seismic activity. However, metal decking may be more expensive upfront and prone to corrosion if not correctly coated or maintained.

4. Concrete Decking

Concrete decking provides exceptional durability and longevity. It can be cast-in-place or precast, offering design flexibility and customization options. Concrete decks resist fire, rot, and insects and provide excellent load-bearing capacity. However, concrete decking requires professional installation and can be more expensive than other materials. It also requires proper waterproofing and periodic maintenance to prevent cracks or deterioration.

Factors to Consider When Choosing Decking Materials

1. Climate and Weather Conditions

The climate and weather conditions in the region where the roof is located play a significant role in material selection. Materials with high moisture resistance, such as composite decking or metal, are recommended for humid and rainy climates. Materials with UV resistance, such as composite or concrete decking, are more suitable in hot and sunny climates.

2. Maintenance Requirements

Consider the maintenance requirements of different decking materials. Wood decking requires regular staining and sealing, while composite and metal decking require lower maintenance. Concrete decking may require periodic inspections and maintenance to prevent cracks or moisture infiltration.

3. Load-Bearing Capacity

The load-bearing capacity of the decking material is essential for the roof’s structural integrity. Metal and concrete decking offer high load-bearing capacity, making them suitable for large roofs or areas with heavy equipment or foot traffic.

4. Aesthetics and Design

The decking material’s choice influences the roof’s overall appearance and design possibilities. Wood decking provides a warm and natural look, while composite and metal decking offers modern and sleek options. Concrete decking allows for customization and can be finished with various textures or patterns.

Comparing Durability and Longevity

1. The Lifespan of Different Decking Materials

The estimated lifespan of decking materials varies. Wood decking typically lasts 10 to 30 years, depending on the type of wood and maintenance. Composite decking can last 25 to 30 years or more, while metal decking lasts 30 to 50 years. Concrete decking is known for its longevity, often exceeding 50 years.

2. Resistance to Environmental Factors

Different decking materials exhibit varying resistance to environmental factors. Wood decking is susceptible to moisture, rot, and insects. Composite decking offers better resistance to moisture and UV radiation. Metal decking is highly resistant to fire but can rust if not adequately protected. Concrete decking provides excellent resistance to fire, moisture, and insects.

Cost Considerations

1. Initial Costs

The initial cost of decking materials varies. Wood decking is generally more affordable, while composite decking tends to have a higher upfront cost. Metal decking can be more expensive, depending on the type of metal chosen. Concrete decking often requires professional installation and can have higher initial costs.

2. Long-Term Cost Analysis

To assess long-term cost-effectiveness, consider maintenance, repairs, and replacement costs. Wood decking may require frequent maintenance and eventual replacement. Composite decking has low maintenance needs, reducing long-term costs. Metal and concrete decking offer durability, minimizing maintenance and replacement expenses over time.

Case Studies and Examples

Examining real-life examples and case studies can provide valuable insights into the performance and longevity of different decking materials. OKC Roofers, recognized as the best roofing company in Oklahoma City, has successfully installed roofs with various decking materials. These case studies highlight the durability and satisfaction of customers based on their chosen materials.


Choosing a sturdy and long-lasting decking material is essential for a roof’s overall performance and longevity. Consider factors such as climate, maintenance requirements, load-bearing capacity, and aesthetics when selecting the material. Each material has advantages and drawbacks, so making an informed decision based on specific needs and preferences is crucial. By carefully evaluating the options and considering long-term costs, homeowners can ensure a sturdy and durable roof that will stand the test of time.
