Our Flat Roof Installation Services Cover all Key Sectors across the UK
Our approved installers work across a wide range of UK buildings, from busy commercial sites to public sector facilities. Each installation is completed using high-performance liquid systems that suit both new roofs and refurbishment projects.
Commercial & Industrial
Installers work across warehouses, offices and industrial units, applying durable liquid systems that perform well on large surfaces and complex layouts. Projects are planned to minimise disruption to daily operations.
Emergency Services
Flat roof installations for police, fire and ambulance buildings use rapid-curing liquid systems that support essential services. Work is scheduled with controlled access to maintain safe and uninterrupted activity.
Education
Schools, colleges and universities benefit from low-disruption liquid systems that suit classrooms, sports halls and administrative buildings. Installations are organised around safeguarding requirements and term-time schedules.
Residential
Suitable for homes, extensions and refurbishments, liquid systems provide a seamless finish that resists leaks, UV exposure and standing water. Installers work with care around existing features and keep disruption to a minimum.
Heritage & Conservation
Ideal for civic buildings, museums and older properties, liquid systems allow precise detailing without altering features. Installers deliver sympathetic refurbishments that maintain character and long-term performance.
Local Authorities
Used across community buildings, housing stock and public facilities, liquid systems provide dependable protection on mixed roof types. Installers plan work to maintain safe access and support long-term asset management.
Consistent Standards
Approved contractors bring proven roofing experience and a strong track record of quality work. They also follow agreed installation practices that align with Allbase system guidance, ensuring every roof is prepared and detailed to a reliable and professional standard.
Specialist in Liquid Systems
Contractors are experienced in applying liquid-applied systems across a wide range of substrates. This ensures the most suitable system is chosen and installed with the right preparation and detailing.
Reliable, Proven Contractors
All contractors are vetted for workmanship, experience and project history. Only companies with a proven track record and strong customer feedback are accepted into the network.
Professional Working Practices
Contractors work to establish site safety procedures that suit homes, commercial buildings and public facilities. Their approach to access, equipment and on-site behaviour ensures a smooth installation with minimal disruption for building occupants.
High-Performance Liquid Systems for New Roofs and Refurbishment Projects
Allbase manufactures and supplies a full range of liquid-applied roofing systems that deliver reliable protection across domestic, commercial and public buildings. These systems create a seamless, fully bonded surface that adapts to a wide variety of roof types and substrates, making them suitable for both new installations and refurbishment work.
Polyurethane (PU)
PU offers an excellent balance of flexibility, durability and versatility, scoring highly across most core areas. It has a moderate odour level during installation, so it is best suited to general domestic, commercial and refurbishment projects where access and ventilation are not restricted.
Polyurea
Polyurea performs at the top end for durability and foot traffic, making it ideal for large commercial and industrial roofs. Its odour level is lower than traditional resins, although not as low as STP. A strong choice where long-term toughness and minimal disruption are priorities.
Silane Terminated Polymers (STP)
STP provides the lowest odour level and the best environmental performance of all systems, making it a reliable option for hospitals, schools, homes and enclosed spaces. It also scores strongly for versatility, giving installers a clean, low-impact system suitable for sensitive or occupied buildings.
GRP (Fibreglass) Systems
GRP delivers excellent foot traffic resistance and a tough, rigid finish, but its versatility and flexibility scores are lower due to the need for OSB decking. It also has the highest odour level during installation, so it is most suitable for garages, balconies and external domestic spaces rather than occupied or enclosed environments.
Basecare
Reliable Warranty Options for Long-Term Peace of Mind
Allbase systems can be protected through our Basecare guarantees, which have been developed to give property owners confidence in both the roofing materials and the quality of the installation. The programme supports projects of all sizes, from domestic extensions to commercial facilities and public buildings, and provides clear, dependable coverage that reinforces the long-term performance of the finished roof.
Get up to 25 years of cover
Our industry-leading Basecare protection plans can provide up to 25 years of coverage for your Allbase product along with a free maintenance plan and unlimited support.
Standard
The standard manufacturer-backed warranty covers the performance of the Allbase roofing system and confirms that the materials used meet our production standards. It applies to qualifying installations regardless of which contractor carries out the work, giving reassurance that the system is supported directly by the manufacturer and designed for long-term protection.
Installation
When an Allbase contractor completes the installation, an additional warranty is provided to support the workmanship. This reflects the contractor’s training, experience and commitment to recognised installation methods, creating combined coverage that protects both the roofing materials and the quality of the installation.
Frequently Asked Questions
We have addressed the most common questions about our flat roof installations to help make the process as straightforward and transparent as possible. With clear guidance, reliable installation practices and a nationwide network of approved contractors, we aim to give property owners and facilities managers confidence at every stage of their project. If your question is not covered below, our team is always available to provide further assistance.
Timescales depend on the size and condition of the roof, but most domestic installations are completed within one to two days. Larger commercial or public buildings may take longer, particularly where access, weather windows or operational hours need to be considered.
Many flat roofs can be refurbished using a liquid-applied system if the existing structure is stable. An approved contractor will assess the condition of the substrate, drainage and detailing to confirm whether a full replacement is necessary.
Liquid-applied systems require minimal equipment and have low noise levels, making them suitable for occupied homes, offices and public buildings. Contractors plan the work to reduce disruption and maintain safe access throughout the installation.
Work is scheduled around the weather conditions needed for the chosen system. Some systems are more tolerant of cooler temperatures, while others require dry conditions. Contractors will plan the installation to ensure the correct environment for a reliable application.
Preparation depends on the condition of the roof, but will include cleaning, repairing damaged areas, priming the surface and addressing any issues with drainage or detailing. Correct preparation ensures strong adhesion and long-term system performance.
The most suitable system depends on the building type, substrate, access requirements and long-term performance needs. Approved contractors will assess your roof and recommend the system that offers the right balance of durability, flexibility, environmental performance and suitability for the site.
Liquid-applied roofs benefit from occasional checks to help maintain their long-term performance, particularly around drainage points, edge details and roof penetrations, and although these systems require very little upkeep, periodic inspections make it easier to identify minor issues before they develop into larger problems. Allbase also provides maintenance plans for property owners who prefer a structured approach to ongoing care, and your contractor or the Allbase technical team can advise on the level of maintenance that suits your roof and its environment.
Allbase offers two Basecare warranty options: a manufacturer-backed warranty that covers the performance of the roofing system, and an additional installer warranty is available when the work is completed by an approved contractor. Together, they provide clear protection for both materials and workmanship.
