Roofing Battens

Explore our versatile range of Treated Roofing Battens, engineered for strength, precision, and long-term performance. Each batten is pressure-treated softwood—typically European redwood or whitewood—to combat rot and insect damage, making them ideal for UK pitched-roof installations.

Whether you're fitting roof tiles, slates, or installing counter-batten ventilation systems, these battens offer dependable structural support and secure fixing points. Their consistent sizes—ranging from 19×38 mm to 25×50 mm—make them easy to specify and align to BS 5534 standards for modern pitched roofing

At TimberOnline (Nottage Timber Merchants), we're proud to supply premium, treated roofing battens from our South Wales base—backed by decades of trust and reliability. Elevate the strength and longevity of your roofing projects with battens designed for performance, safety, and peace of mind.
