How Far Apart Should Roof Battens Be?

Battens should be attached to rafters at 600 mm intervals unless otherwise specified and should span at least three rafters. The battens should be at least 1.2m long to do this.

For more than 200mm gauges, no more than one in every four courses of battens should be linked across one truss. Battens should be attached in a sloping direction rather than straight along the rafter. Again, this will allow for more batten usage.

What Size Should Roof Battens Be?

Batten roofs are available in 25x38mm and 25x50mm diameters and may be supplied in lengths of at least 3m, however, lengths of 3.6m or more are more common.

When installed, they should be at least 1.2m long and span at least three rafters, and the distance between each batten should be at least 40mm.

For longer spans, when two battens are used, they should lie parallel to each other rather than crossing one another. As mentioned above, where two battens are used, they should be linked across a truss.

Do You Need Roof Battens?

Most construction rules do not require the installation of a batten roofing system. In certain circumstances, it is required, but in most cases, utilizing batten on your roof is an option for reaping the benefits of this system.

For roofing, there are two options: a straight-to-deck method or a roof batten system. Straight-to-deck method. Similar to a continuous rafter roof, manufacturers manufacture batten panels that fit right over your decking and cover your roof.

With this method, you’ll need to secure the batten boards with nails or screws. The most common sizes are generally 25x38mm or 25x50mm, but larger roofs have been built as well. First-time installations of these systems will require a professional.

You may also need to hire an engineer to ensure the system is installed correctly for your specific system and will require minimal maintenance. Roof-to-deck system. A type of batten roof where each batten board covers one ridge strip in a pattern similar to a continuous rafter roof.

What Are Roof Battens Used For?

Roof battens are used not only to give roofers a grip but are also an integral aspect of the roof structure. They bear the weights imposed by slates or tiles and snow and wind loads.

Quality battens are increasingly recognized as vital in constructing a secure roof, which is why batten dimensions and specifications are becoming more detailed. The strength of the battens is derived from the quality of the timber.

It is, therefore, vital that you choose a reputable company that uses high-quality materials. Installing battens also allows for better ventilation, which in turn helps to reduce condensation and therefore prevents rot and decay of timbers.

How Do You Attach Roof Battens?

A nail length of 65mm is normally suggested to enable a minimum of 40mm penetration into the rafter. Begin at the roof’s bottom edge, nailing the batten into place in the center of the rafter.

Joints should be installed immediately above the rafters, with the batten square cut, securely butted, and skewed nailed. The batten should be sloped to the roof at 1:30, with a minimum slope of 8.6 degrees from vertical.

Nail gunning is also common but is only allowed when the nails are fired into a hardwood backing board. Spacing for this should be 600mm for 25x38mm rafters and at half the rafter spacing for 25x50mm rafters.

There are 3 basic options for installing & controlling rainwater flow on your property: – Gutters – Downpipes – Drains Gutter systems can be all-inclusive, with gutters and downpipes included, or they can be bought separately.

Can You Install A Tile Roof Without Battens?

The type of batten system employed is frequently determined by the slope of the roof. Battens, for example, may not be required at all on a low-slope roof unless the roof will be subjected to regular or severe rains.

Local construction rules may demand battens and specify how they must be erected on higher slopes. Because of the slope, installing self-supporting tiles at these angles is impossible.

Therefore, battens are required to support the tiles and provide a level of attaching them. This can be done in a number of ways: – sloping battens – stepped battens – continuous batten systems.
