Understanding the BS 5534 British Standard Code of Practice

BSI Code of Practice

The revision of the British Standard Code of Practice affects the contractors, suppliers, and homeowners. Not many understand the basics of the assessment. In the future, all hip tiles and ridges will need mechanical fixing. Challenges affecting heritage roofing and under fixing are long forgotten. This is because the BS 5534 Standard Code provides guidelines that contractors need to follow to ensure quality roofing.

To properly understand the amendment of the Standard Code, here are three major changes:

  1. Underlay regulation: Until the revision was made, the underlay was unregulated in the United Kingdom. For this reason, thin and light roofing materials were used. The code now asks for a test practice to be carried to assess the strength levels and resistance limits of the underlay. Essentially, it’s the underlay that carries the biggest portion of the wind load for both slated and tiled roof.
  1. Mortar bedding not regarded as a fixing: The standard code does not take mortar bedding as a reliable fixing option. Even though the mortar can be used in the roofing process, it needs supplementing. In this case, you can use screws, clips, or nails to do the reinforcement. This means that hips tiles, bedded ridges, and heritage roofing requires mechanical input.
  1. Enhanced wind loading: The code highlights that roof wind loading limits have increased. This means that robust and intensive fixing is required. Practically, it is unlikely that the tiles will require subsequent fixing after advanced enhanced wind loading by the expert. Generally, this is an advantage to all homeowners as they are guaranteed of quality and regulated roofing.

Implications of the Code Amendment to the Roofing Community

The amendment has direct implications for both the contractor and roofing supplier. First, the supplier has a role to play. They are expected to print a zone table on the underlay classifications. This provides the contractor with the right information on the geographical suitability of the underlay. Secondly, the contractor is expected to comply with the measures of the code. They should determine the uplift resistance and wind load for better roofing.
