BROOF(t4) Certification: Raising the Bar for Liquid Roofing Systems

Ensuring Fire Safety & Compliance in Roofing

In the competitive world of construction materials, safety and performance are non-negotiable. Fire resistance is a critical factor in roofing systems, and the BROOF(t4) certification stands as the highest standard for fire safety compliance in the UK and across Europe.

What is BROOF(t4)?

BROOF(t4) certification assesses a roofing system’s ability to resist external fire spread. The evaluation includes:

Surface Spread of Flame – Ensuring minimal fire propagation.
Burning Brands Resistance – Testing durability against burning debris and embers.
Heat Penetration – Measuring heat transfer prevention to underlying substrates.

This rigorous testing guarantees compliance with building regulations while enhancing real-world fire safety, protecting both property and lives.
