Guarantee the durability of the substructure - roof battens

The roof battens nailed across the rafters can be additionally stabilized with roof battens, which are usually made of metal. They are offered for nailing, for screwing or as plug-in attachments. Their installation increases the structural safety of the applied shingles or tiles.

Unilateral to Enveloping

Basically, batten connectors can be mounted anywhere on the roof battens. Common is the placement on rafters, whereby they also compensate for the small area of ​​very narrow rafters, which do not provide enough space for a normal nailing.

Depending on the roof construction and the associated weight load, the roof batten connectors have different shapes with a different number of fixing points. The metal plates, strips or rectangular plug-in elements are mounted on one side, two sides or completely surrounding the joints of the roof battens.

Types and shapes

Standard models of roof battens are used in the following forms.

  • Narrow metal bands connect the battens ends to the sides by means of nailing or screwing.
  • L-shaped metal brackets are placed on two sides of the battens and bolted or nailed.
  • U-shaped roof battens in the width of the roof batten are screwed onto the spar and completely surround the battens.
  • For special constructions such as a greenhouse or a free-standing tent, there are hinge elements in which battens are inserted on both sides, thus forming a durable substructure.

Examples of prices

  • At klokow-gmbh.de, U-shaped roof batten connectors made of steel for the installation of rafters from 1.39 Euro per piece are offered.
  • At mercateo.com, the U-shaped models range from € 1.58 to € 1.83 each, depending on their size.

Tips & Tricks

Roof batten connectors are not mandatory on every roof. In any case, they should be used on lumber that tends to splinter like pine, on very narrow rafters with only one row of nails, and on roofs which are heavily used by weather and wind.
