Roof Battens

What are roof battens?

Roof battens are lengths of wood that are made of rough sawn treated timber, that are laid in-between rafters to secure the roofing felt and are typically used to add a gap between the roof tiles and the roof deck. They are significant in the structure of a roof and serve a wide number of purposes.

How do they work?

Roof battens serve several purposes, such as that they give rigour to the roofing structure and are often used to fit to the roof covering in straight, consistent rows to provide a strong anchor for the nails or clips in the tiles or slates. They are made of very strong materials and can hold a lot of weight. There are certain rules when governing the size and type of battens to be used for roofing and have standards in dictating which size and type can be used for various spacings and roof coverings. The size of a batten is very important to ensure that the roof is strong enough. As any batten measuring less than 25mm in thickness can be considered ‘under-measure’ and should not be used as it could become unstable.

Frequently Asked Questions

How many roof battens do I need per m2?
For plain tiles, battens should be fixed to rafters no more than 600mm apart and should span across at least 3 rafters. For batten gauges over 200mm, no more than one in four courses of battens join over a truss.
How to calculate roof battens?
Measure from the top of the lowest batten to the top of the highest batten, then divide this number by the maximum gauge recommended by the manufacturer, and round this up to the nearest whole number.
