Construction Product Reform: What Roofing and Cladding Buyers Must Demand

Regulation and compliance
A product brochure can describe benefits. It cannot prove that a roof or cladding product is suitable, compatible, correctly installed or supported by the evidence the building owner will need.
Clients should stop accepting product names as a substitute for a complete system, a defined installation method and a traceable evidence route.
Direct answer
Before approving a roofing or cladding product, buyers and specifiers should confirm product identity, current declared performance, intended use, limitations, compatibility with adjoining components, supporting construction, fixing and installation requirements, fire and insurer implications, substitution controls, inspection stages, maintenance requirements and the records that will be handed over. A brochure is only one part of that evidence chain.
Why the reform matters to ordinary roofing and cladding projects
The Construction Products Reform White Paper proposes a more accountable product regime. The detailed legal position will develop, but the commercial direction is already clear: product information must be accurate, traceable and useful to the people selecting, installing and managing the finished building.
This matters on ordinary industrial and commercial projects because roof and cladding systems are assembled from sheets, membranes, insulation, fixings, sealants, closures, rooflights, gutters and interfaces. The performance belongs to the complete installed build-up, not to one familiar brand name.
A brochure answers the easiest questions
| Brochure may tell you | The project still needs to establish |
|---|---|
| Product features and headline performance | Whether those claims apply to the proposed use and complete build-up |
| Available colours, profiles or finishes | Whether the selected variant is compatible with the existing structure and adjoining components |
| General installation guidance | Who owns project-specific design, fixing, interfaces and tolerances |
| Warranty availability | The conditions, inspections, installer requirements and exclusions attached to it |
| Test or certification references | Whether they are current, relevant and correctly applied to this configuration |
What buyers and specifiers should require before approval
- A precise product and system description, not “or similar” without an equivalence process.
- Current technical and performance information applicable to the proposed use.
- Defined supporting construction, fixing zones and structural assumptions.
- Details for rooflights, penetrations, eaves, ridges, gutters, corners and wall junctions.
- Compatibility evidence for insulation, membranes, sealants, coatings and accessories.
- Fire, insurer, environmental and maintenance information relevant to the building.
- A controlled substitution route showing who assesses and approves any change.
- Inspection, photographic, product and warranty records required at handover.
“Equivalent” is not a visual judgement
Two products can look similar and still differ in thickness, coating, reaction to fire, span, fixing, thermal performance, corrosion resistance, compatibility or warranty. A substitution should therefore be treated as a technical and commercial decision, not an availability note from the supplier.
A replacement product is only equivalent when the evidence shows it delivers the required outcome in the actual system and building.
Installation evidence is part of product evidence
A correctly selected product can still fail when installed on the wrong substrate, with unsuitable fixings, poor laps, missing closures or unresolved interfaces. The buyer should know which stages will be inspected and what records will demonstrate compliance with the agreed detail.
At handover, the building owner should receive enough information to identify what was installed, understand the warranty and maintenance conditions and assess future repairs or alterations.
What TCR can contribute during procurement
TCR can review the buildability of proposed roofing and cladding systems, highlight missing interfaces and confirm the installation and handover information required for the specialist package. This does not replace the client’s designers or product manufacturer. It helps ensure that the tender describes something that can be priced, installed, inspected and recorded.

Frequently asked questions
Is the 2026 Construction Products Reform White Paper already final law?
No. It sets out proposals and direction for reform. Project teams should continue following the current legal and contractual requirements while monitoring changes.
Can a contractor propose an alternative product?
Yes, where the contract permits it and the alternative is assessed against the required performance, compatibility, design, warranty and programme criteria.
Who should approve a roofing product substitution?
The responsible client and design team should follow the project change process, using input from the relevant designers, contractor and manufacturer.
What product records should remain with the building?
The agreed specification, product identification, technical data, approved changes, installation and inspection evidence, warranties and maintenance information.
