Dry Fix Roofing

The move towards dry fix products has been accelerated by the large percentage of claims in relation to mortar and its potential to fail, even on new buildings. Mortar has a limited lifespan and requires maintenance as it will deteriorate in time through natural weathering. It is also susceptible to cracking because of the natural movement in the building structure and shrinkage. This can leave the ridge & hip tiles and verges vulnerable to the elements, which can then become dislodged by high winds and strong winds causing additional damage and water ingress and costly internal damage.

What is dry fix roofing and why adopt it?

Dry fix roofing is the method of mechanically fixing products and systems to the roof perimeter without the use of sand and cement mortar. The many advantages of dry-fix roofing highlight why it has been well established in Scotland for some time and now leading the way throughout the rest of the UK and Ireland.

• Simple and quick to install
• Can be installed in any weather
• Semi-skilled fitting procedure
• Mechanically fixed for secure installation
• Compliant with recent BS 5534 and NHBC requirements

BS 5534

As of September 2015, BS 5534:2014+A1:2015 Slating and tiling for pitched roofs and vertical cladding – Code of Practice was revised with the consideration of two main influences; an increase in extreme weather and the alignment of European standards.

The Standard has been developed in order to meet new regulatory requirements and design standards as part of changes to UK Building Regulations, European Eurocodes and industry Technical Standards. Whilst installing to the British Standard isn’t a requirement by law, it can be included with a specification and held up in a court if necessary.

The Code of Practice focuses on three main areas of changes, relating to;

• Fixing
• Mortar bedding
• Underlays

Focusing on mortar bedding, the standard states that mortar alone cannot be used and is insufficient to fix tiles and other fittings. Simply, this means that if mortar is used then additional materials are needed to create a mechanical fix.
