When constructing a sturdy roof system, there’s more to it than just the suitable material. Enter roofing battens, which provide the needed support and protection. These often-overlooked components maintain the structural integrity of your roof. However, in this guide, we will focus on one of their critical aspects: steel roof batten sizes.
Join us as we explore the diverse pros and cons of different dimensions. Plus, we’ll provide invaluable tips to help you choose the perfect fit for all your unique needs!
What Are Roof Battens?
As mentioned in our “What Are Roofing Battens?” guide, these long, thin strips of wood are installed horizontally across the rafters. Usually made of timber (e.g., hardwood), steel, and PVC, they create a secondary framework on which the roof can rest.
Moreover, timber roof battens allow for even distribution across the structure, preventing sagging. The gap they establish between the covering and the underlying deck ensures ventilation. Adequate airflow helps regulate temperature and to avoid moisture buildup and mould growth.
The function of a treated batten doesn’t stop there. It also acts as a barrier against water ingress, keeping rainwater at bay. Overall, this makes battens indispensable in modern roofing systems.

Factors Influencing Roof Batten Sizes:
Selecting the appropriate batten size is influenced by several factors. To start, the type of roofing material used. Heavier materials, e.g., slate, need larger and more robust battens to support their weight. Conversely, lightweight materials, such as asphalt shingles, can utilise smaller timber strips.
The slope of the roof also plays a significant role. Steeper designs require larger slate battens to accommodate the increased gravitational forces. In contrast, smaller ones for low-slope roofs to maintain the angle for water drainage.
Local building codes and regulations further influence batten roof size selection. Building authorities often dictate minimum dimensions. Complying with these codes is essential to passing inspections, and it guarantees the roof’s long-term stability.
Batten Colour:
The issue of what roofing batten colours mean has caused some confusion. While the distinctive red colour of our JB Red Battens does give peace of mind that you are using a BS 5534-compliant batten, this is not necessarily the case for all coloured battens on the market. Please don’t assume that just because it is coloured, a batten conforms to the standard. It must also have the correct stamps and supporting documentation.
Quality Checks:
Ask what quality checks the battens go through. Our timber is quality-checked at every stage of the process. Raw materials are checked for conformity to our buying specifications, and they are also checked before they go through the Goldeneye scanner to ensure no deterioration has taken place. An operator is present during the scan to check for compliance, and the battens are rechecked when the scan is complete. Pieces are also pulled from the production process every hour for a complete quality check for compliance with BS 5534.
Pros and Cons of Different Roof Batten Sizes:
Choosing the correct dimension of steel roof batten is crucial. Larger battens offer increased support and ventilation but may come at a higher cost. Meanwhile, smaller types are more economical but may compromise ventilation and wind resistance.
Advantages of More Miniature Roof Battens:
1. Cost-effective option for lightweight roofing materials.
2. Easier and quicker installation due to lighter weight.
Disadvantages of More Miniature Roof Battens:
1. Reduced ventilation, potentially leading to moisture problems.
2. Less resistance to wind uplift, especially in regions prone to strong winds.
Installation Tips for Roof Battens:
To ensure the proper installation of roof battens, follow these practical tips:
Spacing: Maintain consistent spacing between battens to distribute the roof load evenly. Depending on the roofing material and local building codes, aim for 2 to 4 feet (60 to 120 cm) intervals.
Fastening: Use appropriate fasteners like nails or screws designed for roofing applications. Securely attach battens to rafters or trusses to prevent movement over time.
Alignment: Ensure all battens are aligned perpendicular to the roof’s ridge. This helps maintain a uniform appearance and facilitates the proper installation of the roofing material.
