Liquid applied roofing is an increasingly popular choice for flat and low pitch roofs in the UK, thanks to its seamless, durable, and weather-resistant properties. If you're considering this type of roofing system for your building, understanding the costs involved is crucial for budgeting and decision-making. In this article, we'll explore the various factors that influence the cost of liquid applied roofing installation in the UK.
Factors Affecting Liquid Applied Roofing Costs
Several key factors can impact the total cost of your liquid applied roofing project in the UK:
Roof Size and Complexity
The size of your roof is one of the most significant cost factors. Larger roofs require more materials and labor, resulting in higher overall costs. Additionally, complex roof designs with multiple levels, penetrations, or intricate details can increase installation time and costs.
Type of Liquid Roofing System
Different liquid roofing systems have varying costs. For example, polyurethane systems tend to be more expensive than modified bitumen systems. The quality and thickness of the system also play a role in pricing.
Condition of the Existing Roof Substrate
If your existing roof is in poor condition and requires extensive repairs or preparation work before the liquid roofing application, it can increase overall project costs.
Geographic Location
Labor and material costs can vary depending on your location within the UK. London and the South East generally have higher installation prices compared to other regions.
Average Cost per Square Metre
In the UK, liquid applied roofing costs typically range from £40 to £150 per square metre, including materials and labor. However, these costs can vary based on the specific system and project requirements.
Here's a breakdown of average costs for different liquid roofing systems in the UK:
- Modified bitumen: £40 to £90 per square metre
- Polyester-based systems: £42 to £48 per square metre
- Polyurethane-based systems: £40 to £50 per square metre
Keep in mind that these are rough estimates, and actual costs may differ based on your specific project.

However, the cost-effectiveness of liquid applied roofing membranes in the UK depends on various factors, such as the condition of the existing roof and the specific system chosen.
Additional Cost Considerations
