Why Do You Need Roof Battens?

Roof battens are an important part of your roofing structure. They serve several purposes:

  1. Battens help distribute the roofing material’s weight evenly across the roof deck. This is important, as it prevents the roof from sagging and keeps the roofing material in good condition for longer.
  2. Battens also provide a surface on which the roofing nails or screws can be inserted, holding the roofing material in place. Without battens, the roofing material would likely be less secure and could come loose over time.
  3. Finally, battens help to protect the roof decking from water and weather damage. By redirecting rain and snow away from the roof decking, battens help to keep the decking in good condition, preventing rot and other damage.

What Is The Purpose Of Roof Battens?

Roofing battens or battening, also known as roofing laths, are used to secure roofing materials such as shingles or tiles. Batten spacing on trusses or rafters is determined by the kind of roofing material and is placed horizontally like purlins.

Roof battens are pieces of lumber installed perpendicular to the rafters on the roof deck to provide a nailing surface for roofing materials and to help rafters spread the weight of the roofing materials over the entire roof area.

How Long Do Roof Battens Last?

Most battens come with an industrially applied treatment technique that guarantees a 60-year design life under Use Class 2. BS 8417:2011 Preservation of Wood is the applicable Standard.

The actual life span will depend on exposure to weather and elements like direct sunlight, temperature changes, and high wind velocity. Also, the level of maintenance required will have an effect on the batten’s life span.

Batten lifespan depends on many factors, including how well the batten is installed; how properly the batten is protected and maintained; whether the batten is exposed to corrosive atmosphere or moisture; and how closely a roof’s parapets are secured to the trusses and rafters.
