Roofing & Associated Works Dynamic Market

A Dynamic Market is a procurement vehicle introduced under the Procurement Act 2023, which applies in England, Wales, and Northern Ireland. Scottish contracting authorities can also call off from a Dynamic Market established by a UK body like this one, using the cross-border provisions that apply the Act to that specific call-off. Like a DPS, it allows new suppliers to join at any point during its lifetime, keeping the supply chain open and competitive. The key difference from a framework is that the supplier list is never fixed, and all awards are made through further competition rather than direct award.

The Dynamic Market sits between a framework and a standalone procurement. It provides a pre-established, compliant procurement vehicle with an evaluated supplier pool, so you do not need to set up a new procurement from scratch for each project. But unlike a framework, where you can direct award to a ranked supplier, the Dynamic Market requires a competitive process for every contract. This means more competitive tension on each award, but slightly longer timescales than a direct award.

For roofing procurement, the Dynamic Market structure works well because project specifications vary significantly between buildings, locations, and roof types. A competitive process for each project ensures that the pricing and methodology are tailored to the specific requirement rather than based on generic framework rates. Inprova manages the further competition process for you, including specification development, tender issue, evaluation support, and award, so the additional process does not create additional burden on your team. Contracts can typically be awarded in 10 to 15 days depending on the requirement and evaluation approach.

Yes. The Dynamic Market includes provision for photovoltaic (PV) installation as part of re-roofing programmes across all three lots. This means you can procure a roof replacement and a solar PV installation as a single work package, delivered by a contractor who can do both, rather than running separate procurements for the roofing and the solar.

Combining roof replacement with PV makes practical sense because the roof is already being stripped and rebuilt, scaffolding is already in place, and the structural assessment has already been done. Adding PV at this stage is significantly cheaper and less disruptive than retrofitting it later. For local authorities, schools, and other public sector organisations delivering capital roofing programmes alongside decarbonisation strategies, this integration reduces cost, shortens timelines, and delivers energy benefits from day one.

Lot 3 (projects over £1 million) also includes provision for green and blue roofs and energy efficiency measures supporting decarbonisation and retrofit programmes. For organisations planning estate-wide re-roofing alongside wider sustainability objectives, the Dynamic Market accommodates combined specifications that address both the structural roofing requirement and the environmental improvement in a single procurement.

Inprova’s team can help you develop a specification that integrates roofing and PV requirements, ensuring the evaluation criteria assess both the roofing competence and the renewable energy capability of bidding contractors.

The Dynamic Market accommodates JCT, NEC, and bespoke contract terms without restriction. You choose the contract form that best suits your project and your organisation’s preferences. Inprova does not impose a specific contract format.

JCT contracts are the most commonly used for roofing works in social housing and public sector building maintenance. They provide a well-understood framework for managing variations, extensions of time, and defects. NEC contracts are increasingly used for larger projects, particularly where a more collaborative approach to project management and risk sharing is required. Bespoke terms may be appropriate where your organisation has its own standard conditions or where the project has specific requirements that standard forms do not accommodate.

For each procurement through the Dynamic Market, you set the contract terms as part of the call-off documentation. Inprova supports you with developing the specification and contract documentation to ensure they are consistent and that the evaluation criteria align with the contract approach. Clear KPIs are built into every call-off to support performance management and provide the governance assurance that programme boards and auditors expect. If you are unsure which contract form is most appropriate for your project, our team can advise based on the scale, complexity, and risk profile of the works.

Hospital campuses present specific roofing challenges. Buildings are occupied 24 hours a day, clinical areas cannot be closed for extended periods, infection control protocols restrict construction activity near patient areas, and plant equipment on rooftops needs to remain operational during works. These constraints mean that hospital roofing procurement requires contractors who understand healthcare environments, not just roofing.

Lot 2 covers public and commercial roofing up to £1 million, which is relevant for individual hospital buildings, clinics, and care facilities. Lot 3 covers projects above £1 million, which is relevant for campus-wide roofing programmes spanning multiple buildings. Both lots accommodate the detailed specifications that healthcare organisations typically require around phasing, access restrictions, noise limitations, and coordination with clinical operations.

Because all awards through the Dynamic Market are made through further competition, you can build healthcare-specific requirements into the specification and evaluation criteria for each project. This means you can assess contractors on their experience working in occupied healthcare environments, their approach to managing clinical disruption, and their understanding of infection control and health and safety requirements specific to NHS sites. Inprova’s team can support you with developing a specification that reflects the operational constraints of your estate.

For NHS trusts reporting capital works to trust boards and NHS England, the Dynamic Market’s compliant procurement route and Inprova’s post-award contract management provide the governance trail and performance evidence that healthcare oversight bodies expect.

Yes. Lot 2 is specifically designed for public and commercial roofing projects up to £1 million, covering schools, council offices, leisure centres, libraries, community centres, and other civic buildings. For councils managing diverse property portfolios, this lot provides access to commercial roofing specialists who work with flat roofing systems, single-ply membranes, liquid applied waterproofing, and manufacturer-backed warranty systems that are standard in non-residential construction.

School roofing is a particularly significant category. Many school buildings were constructed in the 1950s, 1960s, and 1970s with flat roof systems that have reached or exceeded their design life. For multi-academy trusts managing dozens of school sites, and for local authorities maintaining the school estate, the procurement challenge is delivering a rolling programme of roof replacements across multiple buildings with different specifications, conditions, and access constraints.

The Dynamic Market supports this by providing a pre-established procurement vehicle that can be used repeatedly without re-procurement. Each school project is competitively tendered, so the specification and pricing are tailored to the specific building. For larger programmes spanning multiple school sites, Lot 3 covers projects above £1 million with the additional governance and project management capability that multi-site programmes require. Inprova’s team can support the programme planning and procurement sequencing that keeps a rolling roofing programme on track across the academic year.

Lot 3 includes provision for green and blue roof systems as part of larger roofing projects. Green roofs (planted roofing systems) and blue roofs (water attenuation systems) are increasingly specified in planning conditions, sustainability strategies, and biodiversity net gain requirements. For public sector organisations required to demonstrate environmental stewardship alongside asset management, the ability to procure green roofing as part of a standard re-roofing project simplifies both the procurement and the delivery.

Green roofs provide benefits including surface water attenuation (reducing flood risk), biodiversity habitat creation, improved thermal insulation, extended roof membrane life (protected from UV degradation), and visual amenity. Blue roofs manage rainwater at source, reducing the volume and rate of surface water runoff from buildings, which is increasingly required by planning authorities and sustainable drainage strategies.

For local authorities and government departments managing civic buildings, green roof specification may be driven by planning conditions, corporate sustainability targets, or biodiversity net gain requirements, whether that’s under the Environment Act 2021 in England, the equivalent framework in Wales, or Scotland’s own approach to biodiversity net gain. For education providers, green roofs on school buildings can support outdoor learning and environmental education alongside the practical drainage and insulation benefits. The Dynamic Market accommodates these specifications within Lot 3, and Inprova’s team can support you with developing the specification to incorporate green or blue roof requirements alongside the core roofing works.

Every contractor admitted to the Dynamic Market has been evaluated against strict technical, financial, and safety requirements. Roofing is one of the highest-risk construction activities, with working at height the primary hazard. Falls from height remain one of the leading causes of workplace fatalities in the UK construction sector, and the Health and Safety Executive in Great Britain, alongside the Health and Safety Executive for Northern Ireland, prioritises enforcement in this area.

The admission criteria for the Dynamic Market require contractors to demonstrate competent health and safety management systems, appropriate insurance coverage, relevant technical accreditations for the type of roofing work they are delivering, and the financial standing to sustain contract delivery. These checks are carried out at the point of admission to the Dynamic Market, providing a baseline level of assurance before any contractor is invited to compete for your work.

At the call-off stage, Inprova incorporates additional due diligence checks to verify that the contractor’s accreditations, insurance, and financial position remain current. This layered approach means you are not relying solely on an initial evaluation that may have been completed months ago. For organisations where safety governance is reported to boards, regulators, or audit committees, the combination of pre-admission evaluation and call-off stage verification provides a stronger evidence trail than a single point-in-time assessment. Inprova’s post-award support includes ongoing performance monitoring that tracks safety alongside quality and programme delivery.

The Dynamic Market is primarily designed for planned roofing works and capital programmes, but the 10 to 15 day award timeline means it can also be used for urgent requirements where a short competitive process is appropriate. If storm damage, a structural failure, or an insurance claim requires prompt action but the works are substantial enough to warrant a formal procurement, the Dynamic Market provides a faster route than running a standalone procurement from scratch.

For genuinely emergency repairs that cannot wait 10 to 15 days, such as making a property watertight after storm damage, most organisations use existing responsive repairs contractors or emergency works provisions. The Dynamic Market is better suited for the planned follow-on works: replacing the damaged roof section, carrying out associated structural repairs, and restoring the property to full condition once the immediate emergency has been addressed.

If you are unsure whether the Dynamic Market is the right route for an urgent roofing requirement, contact Inprova’s team. We can advise on the most appropriate procurement approach based on the urgency, value, and complexity of the works. Where the Dynamic Market is the right route, we can mobilise the procurement process quickly and manage the timeline to get you to contract award as fast as the competitive process allows.

Inprova’s Planned Works framework covers a broad range of planned capital works, which may include roofing as one element alongside kitchens, bathrooms, windows, doors, and other property improvements. The Roofing and Associated Works Dynamic Market is a dedicated procurement vehicle focused exclusively on roofing.

The choice between the two depends on how you are structuring your programme. If roofing forms part of a wider planned works programme where multiple property improvement elements are being procured together, the Planned Works framework may be more appropriate because it provides a single procurement route for the whole package. If you are procuring roofing as a standalone category, with its own specification, contract, and programme management, the Dynamic Market provides a dedicated route with contractors who specialise in roofing rather than general planned works.

The Dynamic Market also offers some advantages that the framework does not. The open supply chain means new roofing specialists can join at any time. The further competition model means every award is competitively tendered against your specific requirement. And the lot structure separates residential from commercial roofing and small from large projects, ensuring you access contractors whose capability matches your project. Inprova’s team can advise on the most appropriate route for each specific requirement, and there is no restriction on using both solutions for different elements of your estate programme.

The Ministry of Defence manages one of the largest property portfolios in the UK, and roofing maintenance is a significant recurring requirement across operational bases, training facilities, accommodation, workshops, and administrative buildings. Many defence buildings were constructed decades ago with roofing systems that are approaching or have exceeded their design life.

Lot 2 covers public and commercial roofing up to £1 million, which is relevant for individual defence buildings requiring roof replacement or repair. Lot 3 covers projects above £1 million across mixed residential and public estates, which is relevant for larger programmes spanning multiple buildings on a defence site. Both lots provide regional supplier coverage across England, Scotland, Wales, and Northern Ireland.

For defence organisations, the Dynamic Market’s further competition model means every contract is competitively tendered, which supports the value-for-money evidence that defence governance and audit require. The ability to use JCT, NEC, or bespoke contract terms provides flexibility to align with MOD standard contract approaches. Inprova’s post-award due diligence and supplier management provides the ongoing assurance that defence estate managers need, particularly on secure sites where contractor performance and compliance are closely monitored. Contact Inprova’s team to discuss your defence roofing requirements and we can advise on the most appropriate lot and procurement approach.”

Warranty structures for roofing works vary depending on the type of roof, the materials used, and the contractor. For flat roofing on commercial and public buildings (Lot 2), manufacturer-backed warranties are a standard part of the specification. These typically cover the waterproofing membrane and associated components for periods of 15 to 25 years, provided the roof is installed by an approved contractor using the manufacturer’s specified system and materials. The Dynamic Market includes provision for professionally designed roofing systems with manufacturer warranties, which is particularly important for non-residential buildings where the roof is expected to perform for decades without major intervention.

For pitched roofing on residential properties (Lot 1), warranties typically cover both workmanship (usually 5 to 10 years from the contractor) and materials (manufacturer warranties on tiles, underlays, and associated products). Some contractors also offer insurance-backed guarantees that provide protection if the contractor ceases trading during the warranty period.

Because all awards through the Dynamic Market are made through further competition, you can specify your warranty requirements as part of the tender documentation and evaluate contractors partly on the warranty package they offer. Inprova’s team can advise on appropriate warranty specifications for your project type and help you structure the evaluation criteria to ensure the warranty terms you need are reflected in the contract. Post-award, Inprova’s contract management support helps ensure that warranty obligations are documented and that any defects arising during the warranty period are addressed.

Many public sector organisations deliver roofing investment through rolling annual programmes rather than single large projects. A council might replace 50 roofs a year across its housing stock, or a multi-academy trust might schedule one or two school roof replacements per financial year. The Dynamic Market supports this approach by providing a compliant procurement vehicle that can be used repeatedly throughout its lifetime without re-procurement.

Each annual tranche of your programme is procured as a separate competition through the Dynamic Market. This means pricing is tested against the current market for each phase, rather than being locked to rates agreed at the start of the programme. In a period of materials price volatility, this competitive approach can protect you from price inflation better than a fixed-rate agreement. It also means the supply chain is refreshed for each phase, because new contractors who have joined the Dynamic Market since your last procurement become available to compete.

For programme planning purposes, Inprova’s team can work with you to schedule your annual procurement cycles so that contracts are awarded in time for work to start when you need it. This includes managing the specification development, tender process, and evaluation for each phase, reducing the procurement overhead on your internal team. For organisations reporting capital programme delivery to boards, elected members, or regulators, the consistent use of a compliant procurement vehicle across multiple years provides a clean governance trail that demonstrates value for money across the full programme.

Asbestos-containing materials are common in roofing constructed before the year 2000, particularly in flat roofing systems, soffits, fascias, and cement-based roof tiles on buildings from the 1960s, 1970s, and 1980s. Any roofing project on a building of that age needs to account for the possibility that asbestos will be encountered during the works. This affects the specification, the contractor capability requirements, and the cost.

Before procuring roofing works, you should commission a refurbishment and demolition asbestos survey (not just a management survey) for the buildings in scope. This identifies whether asbestos is present, where it is, and what condition it is in. The survey findings inform the specification for the roofing works, including whether licensed asbestos removal is required as part of the project.

When procuring through the Dynamic Market, you can build asbestos management requirements into the specification and evaluation criteria. This includes requiring contractors to demonstrate experience in managing asbestos during roofing works, hold the appropriate licences where licensed removal is required, and provide method statements that address asbestos handling, disposal, and air monitoring. Inprova’s team can support you with developing a specification that properly addresses asbestos risk.

If your survey identifies asbestos but you are unsure how it affects the roofing specification, contact Inprova before proceeding. Getting the asbestos management approach right at the specification stage is essential, because discovering it during the works creates delays, additional cost, and potential health and safety issues that are far more expensive to manage reactively.

Yes. Police forces, fire and rescue authorities, and other blue light organisations managing operationally critical buildings can access Lot 2 for individual building roofing projects up to £1 million and Lot 3 for larger programmes. Custody suites, control rooms, fire stations, training centres, and administrative buildings all require roofing maintenance and periodic replacement.

Roofing works on secure buildings come with specific constraints that general roofing procurement does not encounter. Contractor vetting and security clearance may be required for access to certain sites. Work scheduling may need to accommodate operational requirements, including maintaining custody suite capacity or control room functionality during the works. Scaffolding and access arrangements on secure sites may need to meet additional security standards.

Because the Dynamic Market uses further competition for every award, you can include site-specific security and access requirements in the specification for each project. Contractors bid against your actual requirements rather than generic terms, which means the pricing and methodology reflect the real constraints of working on your buildings. Inprova’s post-award due diligence checks provide an additional layer of assurance around contractor suitability before work begins on site, which is particularly important for organisations managing secure or sensitive premises.
