Fire Block Membrane
Pitched Roof - Above Roofing
The Bridgehill Fire Roof Membrane - Pitched Roof Above Roofing is purpose-built for retrofit solar installations on pitched roofs. Installed directly on top of existing waterproofing and beneath the solar PV system, it requires no alteration to the original roof structure.
In the event of a solar panel fire, the membrane expands under extreme heat, forming a fire-resistant barrier that blocks flames and radiant heat from reaching the roof and igniting insulation, timber, or structural elements.
This solution delivers effective fire protection without demolition, roof replacement, or insulation upgrades. Fast to install and minimally invasive, it’s ideal for protecting existing pitched roofs where PV systems are added post-construction.
A new standard
Active Expansion
Upon contact with extreme heat, the material significantly expands.
Thermal Shielding
This expansion creates a robust block that prevents heat transfer to the underlying insulation.
Roof Preservation
By neutralizing the heat transfer, the existing roof structure remains intact, preventing the fire from penetrating the building envelope.

One of the primary advantages of the Bridgehill system is that it eliminates the need to remove existing roofing. It is designed to be installed over your current roof, removing the requirement for expensive and time-consuming demolition.
The membrane acts as an intumescent shield. When exposed to fire from the panels, the material expands to create a thermal barrier that blocks heat transfer, effectively protecting the insulation below and keeping the roof intact.
The Bridgehill Fire Roof Membrane is highly versatile and compatible with most standard industrial roofing materials, including bitumen, foil, and asphalt-based roofs.
