New revisions have been announced to BS 5534 which have seen it updated to include the new BS 8612 Dry Fix Standard.
BS 5534: 2014 + A2:2018 was published on 28th February 2018, and following a four-month transition period for those in the industry to get up to speed it will be effective from 1st July 2018.
Key changes are said to include:
- A widening of the scope to make it absolutely clear that re-roofing and repairs are covered under BS 5534
- The updates have also made things clearer regarding old roofs, and especially for historically or architecturally important buildings where the British Standard may not be appropriate. It advises those working on these projects to consult with the local planning authority for repair or replacement of these roofs
- BS 8612: Dry-fixed ridge, hip and verge systems for slating and tiling spec has now been added to BS 5534 along with BS 8000-0: Workmanship on construction sites
- A revised clause concerning temporary weather protection before the installation of the primary roof covering, aimed at protecting underlay exposure to UV light has been included
- Improved interpretation of the results from the test method for determining the resistance to wind uplift of roof tile clips
- New definitions for low water vapour resistance (type LR) and air permeable underlays
- New definitions for continuous and discontinuous ceilings.
Roof tile manufacturer Marley Eternit has said it welcomes the revisions. Stuart Nicholson, Roof Systems Director at Marley Eternit, explained: “This is the second amendment to BS 5534 since major revisions were introduced in 2014. We were expecting to see the inclusion of the new Dry-fix Standard, but it also includes further changes, particularly addressing some concerns about the application of roof underlays. It is important that roofing contractors and specifiers are aware of the extent of the revisions.”
