Members should seek to comply with both BS 5534 and BS 8612 after 1st July 2018
At the March Slating and Tiling Technical Committee, the NHBC confirmed that the new BS 8612 ‘Dry Fixed Ridge, Hip and Verge Systems for Pitched Roofs’ standard would form part of their June technical newsletter, giving companies time to implement the requirements by 1st January 2019 when the standard becomes enforceable.
However, the second amendment to BS 5534 ‘Slating and Tiling for Pitched Roofs and Vertical Cladding’ code of practice (BS 5534:2014 + A2:2018), which was published on 28th February 2018, will be effective from 1st July 2018 and in Clause 4.15.8 reference is made to BS 8612:
“Users should pay particular attention to the resistance to wind loads, rain resistance and durability performance of dry-fix roofing products. Dry-fixed ridge, hip and verge products should conform to BS 8612. NOTE Proprietary dry-fix products outside the scope of BS 8612 may be used in accordance with Clause 4.6”. (Clause 4.6 Use of Proprietary Products is not covered by a British/European Standard).
This means that by association, BS 8612 could also be enforceable from the 1st July 2018 by individuals, companies or organisations unwilling to provide contractors with a transition period.
Therefore, we advise that any project commencing after 1st July should comply with both BS 5534 and BS 8612 unless members have written confirmation from the client that it is not required.
