How will the new dry fix standard affect housing associations?

// the building envelope

A new British Standard for dry fix roof systems, BS 8612, was launched on 31st January 2018.  Housing associations need to make sure pitched roof specifications reflect the new Standard and ensure that compliant systems are being used on their new and refurbishment housing projects.

Why do we need BS 8612?

Since the introduction of the revised BS 5534, there has been a significant shift in the market with the majority of new build housing now using dry fix systems. However, the popularity of the products means that there has been a huge increase in the amount of systems available. 

While they may look broadly similar, the quality and performance of the components used can vary significantly and there have been concerns about the durability and weather tightness of some cheaper systems.

Therefore, the BSI has developed a new Standard, BS 8612: Dry-fixed Ridge, Hip and Verge Systems for Slating and Tiling, which sets minimum performance requirements for dry fix products for the first time.

What do housing associations need to do?

The introduction of BS 8612 should improve consistency and reduce the amount of inferior systems on the market, but as it is not a legal requirement, all housing specifiers need to make sure the supply chain is using compliant products on their projects.

Therefore, even if they don’t name a specific manufacturer, housing associations should ensure that specifications state that the required dry fix systems must meet BS 8612 requirements or have BBA certification. This will protect the security of the roof, as well as their liability in the event of any future claim and any warranties. 

As the standard of pitched roofing comes under increasing scrutiny, one of the best ways to ensure compliance with both BS 5534 and BS 8612, is to specify a full roof system from a trusted manufacturer.  This also helps to maintain greater control of the supply chain, protecting the original specification and reducing the risk of product substitution further down the line. 

At Marley Eternit, the required dry fix products have been put through rigorous testing to ensure they meet, or exceed, the requirements of the new BS 8612 standard. This means housing associations can have peace of mind that our complete roof system is fully compliant with British Standards, backed up by the assurance of a 15 year system guarantee.
