Types of liquid-applied roofing

There are several different types of liquid-applied roofing system, each with their own benefits and use cases. No matter the size, shape, type, material and complexity of your roof, we have a solution that’ll allow for a hard-wearing, waterproof and aesthetically pleasing end result. All cost-effectively, and with expert installation that causes minimal disruption to you and your home or business.

There are three key liquid-applied roofing products we use: one-component polyurethane, two-component polyurethane and Polymethyl methacrylate (PMMA).

One-component polyurethane

What is it?

One-component polyurethane is a ready-to-use solution that provides a robust, durable and cost-effective waterproofing membrane, resistant to mechanical, chemical, thermal, UV and natural stressors.

What is it best used for?

We typically use this product for small repairs – for example, the sealing of roof details, gutters, terraces and balconies – as it is cost-effective and easy to use.


What is it?

PMMA is a cold-applied, flame-free, self-terminating system with two components: a resin and a catalyst. It cures quickly, supporting traffic after approximately one hour; it can be applied at a low temperature, down to -5°C; and it’s solvent-free.

What is it best used for?

Because PMMA’s coating will adhere to many common construction materials and almost any properly prepared substrate – including steel, concrete and old bitumen roofing – it can provide seamless, durable, resistant waterproofing on the most complex roofs.

We use it on the most challenging projects, as well as for flashing and details, like skylights, fans, railing supports and terraces. There is an incredibly robust balcony and walkway system available in the range too.

We’d be delighted to have a conversation about which product is best for your roofing project.
