Bauder Approved Roofing Contractor - London & South East
Certified Installers of Bauder's Industry-Leading Flat Roof Solutions
DL Jones Roofing Services is a Bauder approved contractor, delivering Bauder flat roofing systems across London and the South East since 1987. Based in South Croydon, our trained installation teams work daily across London, Surrey, Kent, Sussex, and Essex – installing Bauder systems on schools, hospitals, housing association blocks, local authority estates, and commercial properties of all sizes.
Approved installer status means every Bauder system we install qualifies for the full manufacturer’s guarantee of up to 25 years – not just a contractor’s promise. Our installations are delivered to Bauder’s own quality standards, with their technical team supporting complex projects from specification to warranty sign-off. For specifiers and clients requiring a named-system solution for a public sector, commercial, or housing project, DL Jones is the approved Bauder contractor to call.
Why Choose Bauder?
Bauder is one of the UK’s most trusted names in flat roofing. Specified on countless schools, hospitals, public buildings and commercial developments, their systems combine cutting-edge waterproofing technology with full lifecycle support.
Their key benefits include:
Long-term waterproofing performance
System guarantees up to 25 years
Full warm roof and tapered insulation options
Green roof and Solar PV integration
Robust detailing for complex roofs
Bauder is specified on public sector buildings, schools, hospitals, and housing developments across the UK because their systems deliver proven, long-term performance backed by the manufacturer’s own technical and warranty support. For DL Jones clients, Bauder approved installer status means a single system warranty – covering the membrane, the insulation, and the full build-up – of up to 25 years. That single-document warranty eliminates the split liability that can arise between membrane and insulation suppliers when problems occur later. This is particularly valued by local authorities, housing associations, and property management companies managing large roofing programmes where warranty clarity and long-term accountability are essential.
Bauder Systems We Install
Bitumen Membrane Systems
Bauder bitumen membrane systems – torch-applied, cold self-adhesive, or flame-free – are among the most widely specified flat roofing solutions in the UK public sector and commercial market. Multi-layer build-ups provide exceptional durability and redundancy, making them the preferred choice for buildings where long-term performance and minimal maintenance risk are priorities. As Bauder approved installers, we deliver complete warm roof build-ups: Bauder vapour control layers, tapered insulation boards, and waterproofing membrane as a fully integrated, warranted system. Guarantees of up to 25 years are available on qualifying installations.
Bitumen systems are particularly well-suited to schools, housing blocks, local authority buildings, and any project where a named-system specification and manufacturer warranty are procurement requirements.
Single Ply Systems
Bauder single ply membranes – TPO and PVC – are lightweight, fast to install, and highly resistant to UV radiation and thermal movement. They are an excellent choice for commercial units, industrial roofs, new-build developments, and refurbishments where installation programme speed is a priority. Single ply systems can be mechanically fixed, fully adhered, or ballasted depending on roof structure and wind load requirements. Bauder single ply systems carry guarantees of up to 25 years and are compatible with green roof and solar PV overlays.
Their clean, low-profile finish also makes them a strong choice for buildings with rooftop plant or access requirements where a durable, smooth walking surface is needed.
Cold Applied Liquid Systems
Bauder cold applied liquid systems are seamless, flame-free, and suitable for roofs with complex shapes, penetrations, or intricate detailing where a membrane would be difficult to install without risk. The absence of hot works makes them the preferred choice for occupied buildings – particularly hospitals, schools, and care facilities – where hot works are not permitted and the building must remain fully operational throughout. Cold applied systems are fully compatible with Bauder’s insulation and vapour control layers, delivering a complete warranted build-up without the constraints of torch application.
Green Roofs
Bauder’s award-winning green roof systems integrate directly with their waterproofing membranes to create a fully warranted, combined waterproofing and planting solution. Extensive, intensive, and biodiverse build-ups are all available. Our dedicated sustainable and green roofing page covers the full detail on build-up options, biodiversity net gain compliance under the Environment Act 2021, stormwater attenuation benefits, and thermal performance improvements.
Green roofs installed over Bauder membranes carry Bauder’s root-resistant membrane specification and a single system warranty covering both the waterproofing and the growing medium system – which matters significantly for local authorities and housing associations requiring planning compliance and long-term asset protection.
Solar PV Integration
Bauder’s membrane-integrated Solar PV systems allow photovoltaic panels to be built into the roofing system without penetrations – maintaining waterproofing integrity and delivering a single warranted solution for both the roof and the energy system. For commercial and public sector buildings reducing energy costs, meeting net zero targets, or improving EPC ratings, Bauder Solar PV integration is most cost-effective when planned as part of a roof replacement programme. Our solar PV roofing solutions page covers the full detail on financial case, Smart Export Guarantee income, and the integrated installation process.

Recent Bauder Roofing Projects
We recently completed a full flat roof replacement on a residential block in Lingfield, Surrey – installing a Bauder bitumen membrane system as a complete warm roof build-up with tapered insulation to falls. The project was delivered for a housing association client and involved careful programme management to minimise disruption to residents. The completed installation carries a full Bauder system guarantee. View the full project case study.
At a high-specification residential property in Woldingham, Surrey, we installed a Bauderflex cold self-adhesive bitumen membrane system as part of a full roof refurbishment. The project also incorporated solar PV integration – a combination made possible by Bauder’s membrane-compatible solar mounting system. View the full project case study
