Since 2012, the market for flat roofing has shown steady underlying growth to around 31 million m2 in 2016, in terms of the coverage of waterproofing membranes fitted.



Key demand drivers include increased levels of new build and re-roofing activity in key end-use markets notably; commercial offices, schools, distribution centres, infrastructure & utilities buildings, social housing re-roofing and private housing extensions & garages. Maintenance and repair work to private housing roofs is also an important area of activity while demand for green roofs has also begun to show steady growth.

In 2015 there was a slight fall in the overall market, partly due to a drop in the supply of bituminous membranes, as a result of European bitumen refining capacity declining sharply in recent years. Since then there has been some improvement in demand although RBMs continue to lose share to single ply membranes in the commercial / specification market and EPDM membranes and GRP in the domestic extensions and garage roofing sectors.

The waterproofing sector accounts for the largest share of the market in terms of value, followed by insulation products and vapour control layers. While the UK market for bituminous waterproofing systems is concentrated among relatively few suppliers, the supply of single ply membranes and liquid waterproofing is more fragmented.

While there is significant production of bitumen membranes and felts in the UK, import levels are significant. In the single ply and liquid waterproofing sectors, imports account for the majority of supply. Distribution is largely split between the specialist roofing merchants and general builders’ merchants, typically supplying smaller contractors and general builders, and also direct sales to contractors working on large projects.

Growth in demand for single ply has largely been due to a surge in industrial and infrastructure buildings with large-spanning roofs developed in recent years, particularly in retail distribution centres. Other factors behind growth include inherent properties of single ply relative to RBMs – including the wider range of colours, speed of installation and lower costs of insurance for roofing contractors. In the private housing sector, escalating housing costs have driven up demand for garage conversions and extensions, which in turn has underpinned demand for both EPDM membranes and GRP and other liquid roofing systems.

Over the medium term to 2021, it forecast that demand for flat roofing will continue to grow at a steady pace, key drivers being the continuing growth in demand for online retail distribution centres; pressures on housing supply driving up the need for increasing flats construction; increasing office construction output and a likely growth in demand for green roofs. However, the market is expected to show modest growth over the next 5 years.

Factors that may have a negative impact on the market include the worsening skills shortages in the roofing trades and other construction trades, and the current uncertainty surrounding Brexit and the outcome of negotiations over the next couple of years.
