Metal Roof Repair

The main component of a Firestone Metal Roof Repair solution is the RubberGard EPDM membrane. This elastomeric membrane has a cross-linked polymer structure providing superior performance in even the most demanding environments. The flexibility, elongation capacity and elasticity of the membrane allow it to accommodate any building movement.

Key features & benefits

  • High flexibility and elasticity

Firestone RubberGard EPDM membranes are highly elastic and can elongate over 300% in all directions without cracking. They remain flexible at temperatures down to -45°C, offering year-round installation and performance. This flexibility enables the membrane to adapt to the irregular shape of a metal roof and offers excellent lay-flat characteristics.

  • Superior weather and durability

Firestone RubberGard EPDM is a fully cured membrane composed of essentially EPDM polymer and carbon black offering unmatched resistance to ozone and UV radiation. Furthermore, the characteristics of the membrane remain stable and unchanged over time thus providing a sustainable roofing solution. If needed, the membrane can be easily repaired even after decades of service.

  • Economical and easy to install

Firestone RubberGard EPDM membrane can be installed without requiring special tools. It is lightweight and can be installed on metal roofs with limited load-bearing capacity.

  • Fully engineered system

Firestone has developed a complete range of accessories for its RubberGard EPDM membranes to meet the requirements of various installation details found on metal roofs.
