When public sector organisations plan flat roofing works, the decision is rarely just about choosing a product. They also need a procurement route that is compliant, practical, and suited to the realities of live estates, budget pressures, and long-term asset performance. That is where LHC matters. LHC’s frameworks are free to use, designed for public sector clients, and intended to provide a compliant route to procure works, products, and services for the construction, refurbishment, and maintenance of public buildings and social housing.
For roofing specifically, the Roofing Systems and Associated Works (RS5) framework allows public sector clients to source pre-approved contractors and manufacturers for the design, installation, and associated works of traditional and modern roofing systems, including flat roofs. LHC says RS5 can be used across new build, refurbishment, retrofit, and emergency repair projects, which makes it highly relevant to both estate managers and installing contractors working across public sector estates.
Within that framework, traditional flat roofing is a defined workstream, with IKO ranked as #1 supplier for traditional flat roof systems on the LHC RS5M Roofing Systems Framework. That gives this conversation a clear focus: how the framework works, why it matters, and what contractors and estate managers should be thinking about when planning their next project.
About Boby Singh
To help unpack the framework, we asked Boby Singh, Regional Manager for Midlands, London and South East at LHC, to answer some of the questions we hear most often around LHC, RS5M, and traditional flat roofing. Boby has also featured across LHC’s framework content as a presenter, helping explain procurement routes and framework use in practice.
1. What is the LHC roofing framework?
The LHC Roofing Systems and Associated Works framework, RS5, is a public sector procurement route for sourcing pre-approved contractors and manufacturers for roofing design, installation, and associated works. It covers traditional and modern roofing systems, including flat roofs, and is designed to support compliant procurement across public sector projects.
2. What is LHC RS5M in flat roofing?
RS5M is the manufacturer-led element of the framework. In practical terms, it helps connect public sector clients and approved contractors with appointed manufacturers for specific roofing workstreams, including traditional flat roofing, supporting a more structured route to delivery.
3. Why is LHC important for public sector roofing projects?
Because public sector clients need a route that is compliant, efficient, and easier to manage. LHC’s frameworks are built for that purpose, helping organisations procure works and services with more confidence while drawing on pre-approved supply chains and technical expertise.
4. What does the LHC framework cover for traditional flat roofing?
The framework covers the design, installation, and associated works for roofing systems, including flat roofs, across projects such as refurbishment, replacement, retrofit, emergency repair, and new build. That makes it a practical option for a wide range of public sector roofing requirements.
5. Who can use the LHC roofing framework?
It is intended for public sector organisations, including local authorities, social landlords, schools, healthcare bodies, and other publicly funded organisations responsible for buildings and estates. That is why it is especially relevant to estate managers planning roofing works across active sites.
6. What makes IKO the number one for traditional flat roofing on LHC RS5M?
IKO is ranked as the #1 supplier for traditional flat roof systems on the LHC RS5M Roofing Systems Framework. For customers, that signals a strong position within the framework and helps reinforce confidence when considering IKO for public sector traditional flat roofing projects.
7. Why does IKO’s RS5M position matter for installing contractors?
For contractors, it helps provide confidence that they are working within a recognised framework route supported by an established manufacturer. That matters when technical support, system clarity, and smooth project delivery are all high priorities on site and ranked first for Most Economically Advantageous Tender.
8. Why does the LHC roofing framework matter for estate managers?
For estate managers, the value is in having a more structured procurement route for flat roofing projects across maintenance, refurbishment, and new build. It can help reduce complexity when balancing compliance, budget, operational continuity, and long-term asset performance.
9. What makes traditional flat roofing a strong choice for public sector buildings?
Traditional flat roofing remains widely used because it is a proven solution across many building types and project requirements. Within RS5, it is a clearly defined roofing workstream, which supports its use across public sector refurbishment and new-build programmes.
10. What support does IKO offer on LHC flat roofing projects?
IKO presents its offer around technical support, system guidance, and a broad flat roofing portfolio backed by UK manufacturing capability. It also states that its roofing components are designed for compatibility within integrated systems, which can help customers make more informed choices from specification through to delivery.
11. Where does PAS 2080 fit into public sector flat roofing?
PAS 2080 is relevant because it encourages a more whole-life view of carbon across built environment decisions. In roofing, that means looking beyond upfront cost alone and thinking more carefully about durability, maintenance, design choices, and long-term outcomes as part of project planning.
12. Why should contractors and estate managers speak to IKO about LHC RS5M?
Because they are not just choosing a roofing product. They are choosing a route for delivery. IKO’s position on LHC RS5M for traditional flat roofing, combined with its technical support and broad flat roofing offer, helps give customers confidence in both the framework fit and the support available around the project.
