Tanalised roofing batten Type A in 19mm x 38mm is the standard pressure-treated batten used to fix tiles and slates on pitched roofs across the UK. Manufactured from European Redwood or Whitewood and treated green against rot and insect attack, it provides a reliable, consistent fixing line for new builds, repairs, and extensions.
Specifications
| Property | Detail |
|---|---|
| Material | European Redwood or Whitewood |
| Treatment | Tanalised (pressure-treated), green |
| Grade | Type A Roofing Batten |
| Nominal Size | 19mm x 38mm |
| Lengths Available | 4.2m, 4.5m, 4.8m |
| Profile | Regularised, sawn |
| Use Class | External (above ground, covered) |
What it's used for
- Fixing clay and concrete roof tiles on new-build and replacement pitched roofs
- Laying natural slate and fibre cement slates on domestic and commercial roofing projects
- Re-battening during roof repairs, re-tiling, or insulation upgrades
- Secondary structural roles in garage, shed, and outbuilding roof construction
Fitting and handling
Tanalised batten should be stored flat and off the ground on a level surface before use, allowing air to circulate around the stack. When fixing, use ring-shank or spiral-shank nails to maintain a firm hold through seasonal movement, and ensure battens are spaced to the tile or slate manufacturer's recommended gauge. Cut ends exposed during installation should be treated with an end-grain preservative to maintain the integrity of the treatment.
FAQ
What is the difference between Type A and Type B roofing batten?
Type A roofing batten, such as this 19mm x 38mm section, is the most widely used size for standard plain tiles and slates on residential pitched roofs. Type B batten is larger in section and is specified where heavier tiles or wider rafter spacings require additional load-bearing capacity. Always check your tile manufacturer's fixing specification before ordering.
Is Tanalised green batten safe to use on a roof once the treatment has dried?
Yes. The green colour comes from the copper-based preservative used during the pressure treatment process. Once the batten has dried and any surface moisture has evaporated, it is safe to handle and install in the normal way. Gloves are recommended during handling as a general precaution.
What length of roofing batten should I order for my roof?
The 4.8m length suits most rafter spans and minimises offcut waste on larger roofs. The 4.2m and 4.5m lengths are useful where access or storage is restricted, or where shorter spans mean less waste. Calculate your total linear metres required, add 10 to 15 per cent for cutting waste, then select the length that best matches your rafter centres.
