Solar PV Roofing - London & South East | Commercial & Public Sector
Integrated Solar Roofing for Energy-Efficient Buildings
Energy costs for commercial buildings, schools, hospitals, and housing blocks have risen dramatically in recent years – and the pressure on facilities managers, local authorities, and property owners to reduce operational costs while meeting sustainability targets has never been greater. Solar PV roofing offers one of the most compelling solutions available: generating clean electricity from what is often one of the largest unused assets on any building – the roof.
DL Jones Roofing Services delivers fully integrated solar PV roofing across London and the South East – treating the roof and the energy system as a single engineered solution, not an afterthought. As approved installers of Bauder and Polyroof roofing systems, every solar PV installation we deliver is integrated with the waterproofing membrane and insulation – creating a single warranted solution for both the roof and the energy system, backed by the manufacturer’s guarantee. Our teams operate daily across London, Surrey, Kent, Sussex, and Essex.
What Is Integrated Solar PV Roofing?
Integrated solar PV roofing goes beyond simply placing solar panels on top of an existing roof. It treats the solar system and the roof itself as a single engineered solution – the panels are incorporated into the roof structure, working in conjunction with the waterproofing membrane and insulation rather than being bolted on as an afterthought.
This integrated approach delivers three advantages that a bolt-on retrofit cannot. First, it avoids the penetrations and fixings associated with retrofit panel installations – the leading cause of waterproofing failures on buildings with poorly installed solar arrays. Second, it produces a cleaner, more aerodynamic profile that performs better in wind and presents better aesthetically. Third, and most importantly for commercial and public sector clients, it creates a single point of responsibility for both the roofing and the energy system – one contractor, one warranty, one point of accountability.
When solar PV is incorporated into a planned flat roof replacement programme – the most cost-effective timing for an integrated installation – the incremental cost of adding the solar system is significantly lower than a retrofit installation. The roof is being replaced in any case; the marginal cost of integrating solar at that stage is considerably lower than returning separately to install it later.
Our Solar PV Capabilities
Flat Roof Solar PV Systems
Best for: Schools, hospitals, council buildings, office blocks.
Pitched Roof Solar PV
Panel-mounted systems designed for tile or metal pitched roofs use integrated fixing systems that work with the existing roof covering – preserving weatherproofing and avoiding damage to the underlying materials. All pitched roof solar PV installations are carried out in conjunction with our pitched roofing team, ensuring the roofing and solar elements are fully integrated from the outset and that the fixing and flashing detailing maintains the weathertight integrity of the roof.
Most solar PV installations on commercial buildings do not require planning permission under permitted development rights – but there are exceptions for listed buildings, conservation areas, and installations that exceed certain size thresholds. We advise on planning requirements at the survey stage.
Best for: Housing schemes, public buildings, mixed-use developments.
Solar Roofing with Warm Roof Upgrades
Best for: Sustainable refurbishments, long-term energy savings.
Battery Storage & Monitoring Options
Ideal for: Schools, offices, and sites with off-peak usage.

Frequently Asked Questions
Can I install solar panels on a flat roof during re-roofing?
Yes – and this is the optimal time to install solar PV on a flat roof. When solar PV is incorporated into a planned flat roof replacement programme, the incremental cost of adding the solar system is significantly lower than a retrofit installation – the scaffold is already erected, the roof is already being accessed, and the waterproofing and solar mounting system can be designed as an integrated solution from the outset.
Installing solar at the same time as a new Bauder or Polyroof roofing system also ensures the solar mounting system is fully compatible with the manufacturer’s waterproofing warranty – avoiding the penetrations and fixings associated with retrofit installations that can compromise waterproofing integrity. Call 020 8657 0734 or request a free survey to discuss combining your roof replacement and solar PV installation.
What ROI can I expect from commercial solar PV?
Do solar panels compromise my roof’s waterproofing?
Can you help meet BREEAM or public sector carbon targets?
Yes – solar PV roofing is one of the most direct ways for local authorities, housing associations, and NHS trusts to make measurable progress against carbon reduction commitments and net zero targets. For BREEAM assessments, solar PV contributes directly to the Energy credits section – potentially delivering credits that move a building from one BREEAM rating to the next.
We can provide the system specifications, projected generation output data, MCS certification documentation, and commissioning reports required for BREEAM assessment submissions, public sector sustainability reporting, and planning applications requiring carbon reduction evidence. We also advise on the interaction between solar PV and the green roof systems we install – both can be accommodated on the same roof area where appropriate.
Do you offer battery storage or monitoring services?
