Paving the Way for Fire Safety: Holrow’s 2026 Commitment to the Modular Roofing Sector

Fire Compliance in Modular Roofing: Holrow’s Focus for 2026

As the modular construction sector continues to grow at pace, the conversation around fire safety is becoming increasingly important — particularly when it comes to roofing systems. Speed, repeatability, and efficiency are central to modular construction, but these priorities must sit alongside robust, well-understood fire compliance.

Looking ahead to 2026, Holrow will be placing a clear and deliberate focus on supporting the modular sector with fire compliance under the roofing discipline.

Why Modular Roofing Deserves Greater Attention

Roofing systems in modular construction are often complex assemblies, combining multiple components, substrates, membranes, insulations, and adhesives. While individual products may carry fire classifications, compliance is determined by how these elements perform together as a complete roof build-up.

In our experience, fire risk in modular roofing is rarely the result of poor intent. More often, it stems from:

• A lack of clarity around compliant roof build-ups
• Misinterpretation of fire test data and classifications
• Build-ups evolving over time without reassessing fire performance
• Uncertainty around what building control will accept

These challenges can create unnecessary risk, delays, and cost — particularly when fire compliance is questioned late in the design or construction process.

Holrow’s Role: From Uncertainty to Confidence

Holrow’s focus for 2026 is simple: to help modular manufacturers move from uncertainty to confidence when it comes to fire compliance in roofing.

We will be working alongside modular companies to provide clear, practical, and evidence-based support, helping them understand not just what is required, but why it matters and how to achieve it.

Supporting Compliant Roof Build-Ups

A central part of our offering will be direct support around roof build-ups and system understanding.

Fire performance cannot be assessed in isolation. It must reflect the real-world roof assembly being installed in factories and on site. Holrow will assist modular manufacturers by:

• Reviewing existing roof build-ups used across projects
• Supporting the development of compliant warm roof solutions suitable for modular construction
• Helping interpret fire test data to ensure it is relevant to the actual build-up in use
• Identifying gaps between product approvals and system-level compliance
• Providing clear documentation and guidance that can be relied upon during building control review

Our aim is not to slow down modular construction, but to strengthen it — ensuring roofing systems are compliant, defensible, and future-proofed.

A Collaborative Approach to Fire Compliance

Fire compliance should not be seen as a barrier to modular construction, but as an integral part of delivering safe, high-quality buildings at scale. Holrow’s approach is collaborative, working with manufacturers, designers, product suppliers, and testing bodies to align intent with evidence.

By taking a proactive approach to fire compliance in roofing, modular companies can reduce risk, avoid costly redesigns, and maintain confidence throughout the delivery process.

Looking Ahead to 2026

Holrow’s commitment for 2026 is clear: to support the modular sector with specialist fire compliance expertise under the roofing discipline, providing clarity where it is often lacking and practical solutions where they are most needed.

If you are a modular manufacturer looking to strengthen your approach to roofing fire compliance, we would welcome the conversation.
