The Liquid Roofing and Waterproofing Association (LRWA) has launched a new online training course, which is the first of its kind to independently introduce the sector.

The ‘Foundation in Liquid Applied Flat Roofing’ covers six modules designed to help candidates understand how to design and install liquid-applied membranes, flat roofing, and other types of waterproofing such as balconies.

The training is aimed at all those involved in the flat roofing industry, including specifiers and people working in marketing, sales, distribution, manufacturing, and technical support.

Explaining the drivers for launching the course, Sarah Spink, CEO of the LRWA, said: “There are now 11 liquid chemistries available in the UK, all with different qualities and designed for a variety of applications. Gaining a better understanding of this diverse market will ensure individuals are better equipped to carry out their role, especially those who are new to the sector.    

“Supporting people to enhance their knowledge also aligns with wider changes happening across the construction sector. Post Grenfell, there is a growing need to demonstrate competence when specifying, installing and maintaining construction products across all disciplines.

“In the liquid roofing and waterproofing sector, that means specialist training is not only essential for roofing contractors, but those who work off site and across the entire supply chain.”

Following funding from the Roofing Industry Alliance, the Foundation in Liquid Applied Flat Roofing is hosted on a new online platform called the LRWA Online Training Academy. It is equivalent to around five to six CPD learning hours, which candidates can complete at their own pace over 10 weeks.

The first module covers the main types of flat roof construction, and the building materials used for structural decks. Green roof systems are also detailed in this section along with the definitions of a roof terrace and balcony.

Module two introduces the key building regulations and minimum standards that need to be referred to when designing flat roofs.

The different types of liquid-applied membranes are explained in module three as well as an overview of the other materials that can be used in flat roof construction such as insulation and carrier membranes.

Candidates will learn more about the planning stages of flat roofing in module four and module five covers key health and safety considerations.

Video is used extensively in the final module to demonstrate the installation of different liquid applied membranes, including cold-applied bitumen, polyester, hot melt, polymethyl methacrylate (PMMA), and both single and twin pack polyurethane.

At the end of each module is an online assessment to test the candidate’s understanding of each topic.

The LRWA Foundation in Liquid Applied Flat Roofing is in the process of being certified by the CPD Certification Service and is available to members and non-members. It costs £30 to take part.
