A Guide To Roofing Battens

Roofing battens are a crucial component in the construction of a secure and durable roof. For homeowners involved in a new build project or refurbishing an existing property, using the correct battens ensures stability, weather resistance, and compliance with industry standards. In this guide, we’ll explore what roofing battens are, their common uses, and the requirements set for strength, size, and treatment.

What are roofing battens?

Supporting the structure of a roof

Roofing battens are narrow lengths of construction timber fixed horizontally across roof rafters. They provide a secure base for roofing materials such as tiles, slates, or shingles. By creating a raised surface, battens allow for proper drainage and ventilation, preventing moisture from becoming trapped beneath the roofing material.

Although often hidden from view once the roof is complete, battens are a key structural component. They distribute the weight of tiles evenly, improving the overall strength of the roof. They also act as a fixing point for nails or clips, helping tiles remain securely in place even in adverse weather conditions.

Why roofing battens are important

Ensuring strength and stability

The correct choice and installation of roofing battens contribute to the long-term durability and safety of a roof. They help to maintain the correct spacing for tiles, ensuring uniform coverage and preventing gaps that could lead to leaks or drafts. Well-installed battens also provide a foothold for roofers during construction or maintenance, making work at height safer.

Roof battens must meet British Standard BS 5534, which sets requirements for their strength, size, and treatment. This ensures they can withstand the loads imposed by tiles, wind, and snow. Using battens that fail to meet this standard could compromise the integrity of the roof, leading to costly repairs or replacements.

Why are some roofing battens are blue?

Marking graded and treated timber

Roofing battens are sometimes coloured to indicate that they have been graded and treated to meet industry standards. Blue roofing battens, for instance, have been treated with a blue-tinted preservative to show that they comply with BS 5534. This makes them easy to identify and ensures builders can confidently select the right product for structural roofing work.

Other battens may be coloured red or gold, but the colour itself does not determine the quality. Instead, it serves as a quick visual reference for graded battens. It is always important to check markings on the timber to confirm its compliance with industry standards before use.

What are blue roofing battens are used for?

Providing a secure base for roofing materials

Blue battens are designed for use in roofing applications where a strong, reliable fixing base is needed. They support a range of roofing materials, including concrete and clay tiles, fibre-cement slates, natural slate, and metal shingles. Their role is to create a stable framework that helps tiles remain securely attached while allowing for necessary ventilation.

Alongside the securing of roofing materials, battens also aid installation by providing a guide for tile placement. Properly spaced battens ensure consistency across the roof, reducing the risk of misalignment. By elevating the tiles, they also contribute to water runoff, helping to prevent leaks and prolong the lifespan of the roof structure.

Choosing the right roofing battens

Meeting size, treatment, and compliance requirements

Selecting the right battens for a project involves considering size, treatment, and compliance with industry standards. According to BS 5534, roofing battens must be at least 25mm thick to provide sufficient strength. They should also be treated to Use Class 2 standards to protect against decay and insect damage.

Fountain Timber’s blue battens are fully graded, meaning they have been assessed for strength and durability. Each bundle contains ten battens measuring 4.8m in length and 50mm x 25mm in size, making them suitable for various roofing projects. The blue treatment confirms that they meet the necessary strength requirements, ensuring peace of mind for both builders and homeowners.
