The National Federation of Roofing Contractors (NFRC) is advising its members that they should comply with both BS 5534 and BS 8612 roofing standards 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 be highlighted in their June technical newsletter, giving companies notice to implement the Standard’s requirements by 1st January 2019 when it becomes enforceable.
In addition, 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 also be effective from 1st July 2018 and in Clause 4.15.8 it refers the need to comply 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 clause means that, in effect, BS 8612 could also be enforceable from the 1st July 2018 by individuals, companies or organisations unwilling to provide contractors with a transition period.
In the light of these facts, NFRC is advising that any project commencing after 1st July should comply with both BS 5534 and BS 8612 unless contractors have written confirmation from the client that it is not required.
The update to BS 5534:2014 + A2:2018 was designed to further improve the security, durability and weather-tightness of new and refurbished pitched roofs. In part this is achieved by referring to the new dry fix standard, BS 8612:2018, which sets out standards for dry fix roofing products and systems, in response to issues of product quality and installation issues.
The February updates include:
- Clarification of the scope of the standard in relation to old and heritage roofs
- Addresses ongoing sitework issues relating to the permissible drape of unsupported roof underlays, their product testing and classification for wind uplift resistance
- Improves interpretation of test results from the test method to determine the uplift resistance of mechanical fasteners for roof tiles, leading to more accurate fixing specifications
- Makes minor corrections and updates references, including to a new standard: BS 8612:2018 – Dry-fixed ridge, hip and verge systems for slating and tiling – Specification
- Supports BS 8000-6:2013 Workmanship on building sites. Code of practice for slating and tiling of roofs and walls
