Getting Started with Liquid Roofing
What is liquid roofing?
Liquid roofing is often referred to as liquid rubber roofing, an acceptable term, used widely across the industry. Some of the highest performing systems consist of a liquid PU-based, synthetic product mixed with an accelerator. These often contain a self-levelling compound, to ensure an even coating across a flat roof surface in a single coat without overworking.
Liquid roofs have been commonly used in complex roofing systems where membrane cannot be installed. These have been typical of commercial roofs with multiple extrusions or of concrete construction. In these instances, liquid coatings can seal and protect, fast curing to form a membrane-like encapsulation of the surface.
A versatile roofing system, it is becoming increasingly popular in the domestic sector, meeting precise needs for a wider range of applications.
Features of liquid waterproofing systems
Covers most substrates
The latest liquid roofing systems are making waterproofing easier in the domestic sector with the width of range in terms of coverage. Traditionally, materials have been limited for certain types of substrate, making some domestic projects complex and demanding professional installation as a result.
The flexibility delivered by liquid coatings has meant that homeowners have a new approach to reaching the parts that membrane simply can’t. One that has opened new doors in the domestic market sector.
Liquid roofing systems can easily accommodate most commonly-found substrates:
The applications of liquid roofing products

Residential Roofing
Flexible, durable and straightforward to apply, liquid coatings are suitable for a wide range of residential roofing projects:
- Flat roofing
- Buried and inverted roofs
- Roof terraces and balconies
- Garage roofing
- Green and other types of eco-roofing
- Complex roofing with multiple extrusions

Anti-slip Surfacing
Some of the most innovative liquid roofing systems have a much wider scope of use, suitable for projects other than roofing. For example, the simple addition of an anti-slip medium to liquid PU can make safe garden steps or create a safe pool play zone.

- Car parking zones
- Balconies and terrace
- Gutter and drain humidity protection
- Sealing chimneys, upstands, balcony penetrations
- Hairline crack sealing and other repairs
Installing a liquid roof
Installing a liquid rubber roof is typically super-smooth and fast. It cures quickly and is effective almost straightaway once correctly applied over an adequately prepared substrate.
Preparation is an important part of the process, as with most other major roof projects. It is important to refer to the installation guidelines and ensure that adequate preparation is completed before application. This is the best way to ensure the maximum performance possible.
Liquid roofing isn’t complicated to install, as it involves applying a mixed product in a single coat using a series of foam or other high quality paint-type rollers. There is a reinforcing bandage embedded into the coating and topcoat to seal and complete the finish where required.
What tools do you need?
It couldn’t be easier to install your liquid membrane and basic tool list reflects the simplicity of this product.
It is also recommended that you protect fascia and soffits, gutters and any other visible trim from potential drips or runs. Cover these with masking paper to simplify cleaning following application of the roofing system.
Finding a professional installer
DIY isn’t for everyone and although straightforward to apply, there is a process which must be followed. To get the most out of a high performance system, the preparation and installation has to be carried out to the highest possible standards.
It is important to realise your limits and boundaries and know when to call in a professional installer. It may be faster, and cost less than you think. For a professional installation, use a recommended and trained installer – find one local to you here.

Being cold applied, often in a single coat makes it safer and faster to apply than other types of waterproofing. As it can also be applied to a wider range of substrates and even cover some types of existing covering, it can sometimes offer a more flexible approach than membrane for homeowners tacking complex projects.
