What is Liquid Flat Roofing?

Liquid flat roofing involves applying a liquid coating directly to the roof surface. As it cures, it forms a seamless waterproof membrane that protects the building from all weather conditions. It can be used on both new roofs and refurbishment projects. The coating can be easily applied around rooflights, vents, outlets and awkward areas, making it an ideal solution for complex roofs.

Liquid Roofing for Flat Roof Refurbishment

Liquid systems are a popular choice for flat roof refurbishment. They can often be applied over a suitable existing roof, reducing disruption and potentially avoiding the cost of a full replacement. AAC provides tailored refurbishment solutions for a range of commercial and industrial applications. This approach restores waterproofing, upgrades insulation, protects ageing roofs and extends their service life.

When to Choose Liquid Flat Roofing

Liquid flat roofing is great for waterproofing intricate areas. It is the ideal choice when a roof has awkward detailing or multiple penetrations, such as vents, outlets and rooflights. Its flexible application also makes it useful for areas with difficult access. The straightforward installation process helps minimise disruption, making it a practical choice for occupied buildings.

Our Liquid Flat Roofing Installation Process

Our process is straightforward and follows five practical steps to ensure a successful application.

Roof Survey: We assess the roof’s condition, layout and existing materials to determine the right specification.

Roof Preparation: The surface is cleaned and prepared to create a suitable base for the new waterproofing system.

Primer: Where required, a compatible primer is applied to help the membrane bond securely to the roof.

Liquid Membrane Application: The liquid coating is applied across the prepared surface and around roof details before curing into a fully bonded waterproof membrane.

Inspection and Handover: We inspect the completed roof before providing the relevant warranties, documentation and maintenance guidance.
