When it comes to roofing, particularly complex jobs or refurbishment projects, cold applied liquid systems have become an increasingly popular solution. Known for their flexibility, ease of installation and waterproofing performance, these systems offer a modern alternative to traditional roofing materials.
Composites Construction UK works with a wide range of innovative construction materials and solutions, including cold applied liquid roofing systems. In this blog, we’ll take a closer look at the pros and cons to help you decide whether this type of system is right for your project.
What is a cold applied liquid roofing system?
A cold applied liquid roofing system is a seamless, fully bonded waterproofing membrane that’s applied as a liquid and then cures to form a solid, protective layer. Unlike other roofing systems that require heat or open flames during installation, cold applied systems are applied at ambient temperatures using rollers or brushes. These systems are ideal for flat roofs, complex detailing and refurbishment projects where traditional membranes may be difficult or hazardous to install.
The advantages of cold applied liquid roofing systems
The numerous benefits of cold applied liquid roofing systems make them a popular choice for a wide range of sectors.
Safe and flame-free application
One of the best features of cold applied systems is the lack of heat required during installation. There’s no need for gas torches or hot works permits, which significantly reduces fire risk and makes the system safer to apply. This is especially useful in sensitive environments such as schools, hospitals or occupied buildings.
Seamless waterproofing
Thanks to the liquid curing as one continuous membrane, there are no joints or seams for water to penetrate. This results in a highly effective waterproofing solution which is less prone to leaks compared to systems with welded or bonded seams.
Ideal for complex roof shapes
Cold applied liquid roofing systems can easily adapt to intricate roof geometries. This makes them particularly useful for refurbishment projects where unusual roof layouts or awkward detailing may make traditional methods impractical.
Fast curing and minimal disruption
Modern cold applied systems can cure quickly, sometimes in just a few hours. This reduces downtime and disruption to the building and its surroundings.
Long-lasting protection
Many cold applied liquid roofing systems offer life expectancies of 20-30 years with proper maintenance, providing long-term value. They’re also resistant to UV, standing water and weathering.
Are there any drawbacks to cold applied liquid roofing systems?
We want to give you all of the information required to make an informed decision, so here are some additional factors to consider.
Weather dependency
Cold applied liquid systems require dry conditions for successful application. Moisture, rain or humidity can interfere with adhesion and curing, which may lead to delays during installation.
Surface preparation is crucial
To achieve maximum performance, the substrate must be properly cleaned and primed. Poor preparation can lead to issues with bonding or curing, which could compromise the integrity of the system.
It’s not always the cheapest option
Although cold applied liquid roofing systems offer long-term value, the initial cost can sometimes be higher than other roofing options. However, when you factor in reduced labour time, lower risk and minimal disruption, many clients find the overall investment worthwhile.
Is a cold applied system right for your project?
If you’re working on a flat roof refurbishment, a complex structure or a site with fire safety considerations, cold applied liquid roofing systems can offer a safe, effective and reliable solution. If you’re unsure whether it’s right for your project, our experienced team can advise on the most suitable products and installation methods to ensure a durable, high-performance finish.
