Liquid roofing refers to low-slope roof systems designed to provide reliable waterproofing on homes and commercial buildings. Installed with correct falls for drainage, insulation and (where required) a vapour control layer, modern liquid roofs use membranes such as bitumen felt, EPDM rubber or GRP fibreglass to create a durable, low-maintenance finish. Ideal for extensions, garages and large commercial areas, liquid roofing offers clean lines, energy efficiency and quick installation—with options for rooflights, terraces and solar—backed by professional warranties.

How does Liquid Roofing work?
Liquid roofing with a liquid coating creates a seamless, fully bonded waterproof membrane over a prepared and insulated roof deck.
A vapour control layer and rigid insulation form a warm-roof build-up, while the reinforced liquid system cures into a single, joint-free skin that wraps neatly around outlets, upstands and penetrations. The UV-stable top finish resists standing water and British weather, delivering long-term performance with low maintenance—ideal for both refurbishments and new builds, and available in a choice of finishes to suit your property.
Is Liquid Roofing the Right Roofing for You?
Liquid roofing is a smart, cost-effective choice for commercial units, warehouses, schools, healthcare sites, apartment blocks and residential extensions.
Modern liquid roof systems—whether cold-applied liquid, bitumen felt, EPDM rubber or GRP fibreglass—deliver a seamless, fully waterproof membrane that stands up to British weather and reduces maintenance. With the right specification, professional installation and routine care, a liquid roofing system offers long-lasting protection, clean modern aesthetics and strong value for money across both refurbishment and new-build projects.
Frequently Asked Questions.
Our frequently asked questions about Liquid Roofing.
Liquid roofing is a low-pitch or level roof structure that uses materials such as felt, EPDM rubber, or GRP fibreglass to create a watertight surface. It’s commonly used on extensions, garages, commercial buildings, and garden offices. Homeowners choose liquid roofs for their affordability, modern look, and ability to maximise usable space.
The lifespan of a flat roof depends on the material used and how well it’s maintained. Felt roofs typically last 10–20 years, EPDM rubber can last 25–30 years, and GRP fibreglass can exceed 30 years with proper care. Regular inspections and timely flat roof repairs can help extend the life of your roof and prevent costly damage.
Flat roofs can be more vulnerable to leaks if they’re poorly installed or not maintained, as standing water may collect on the surface. However, with high-quality materials and professional installation, a flat roof can be just as reliable as a pitched roof. Adding good drainage and scheduling routine checks will keep it watertight and durable for many years.
The cost of a liquid roof in the UK varies depending on size, materials, and complexity of installation. On average, prices range from £40–£90 per square metre, with felt being the most affordable, EPDM mid-range, and GRP fibreglass at the higher end. Despite the upfront cost, many property owners find liquid roofs to be excellent value thanks to their durability and ease of maintenance.
