Marley has
welcomed revisions to BS 5534 which have seen it being updated to include the
new BS 8612 Dry Fix Standard.
Stuart Nicholson,
roof systems director at Marley, comments: “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.”
BS 5534:2014 +
A2:2018 was published on 28 February 2018, with a four month transition period
and will be effective from July 1 2018
Key changes include:
- The scope has been changed to
make it absolutely clear that re-roofing and repairs are covered under BS
5534
- The scope has also made it
clearer regarding old roofs, and especially for historically or
architecturally important building that the British Standard may not be
appropriate and advise to consult with the local planning authority for
repair or replacement on these roofs
- BS 8612: Dry-fixed ridge, hip
and verge systems for slating and tiling – specification, has now been
added into BS 5534 along with BS8000-0: 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
- 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
There are also
numerous other minor revisions to BS 5534. For further information, visit the website.
