Built up Felt Roofs

Felt roofing systems, also known as bituminous roofing or built-up roofing (BUR), are a traditional and widely used method for waterproofing flat and low-pitched roofs.

These systems consist of multiple layers of bitumen-saturated felt sheets, which are bonded together using heat, adhesives, or self-adhesive properties.

Key Features of Felt Roofing Systems

1. Multi-Layer Protection – Built-up layers provide enhanced durability and resistance against the elements.
2. Proven Longevity – most felt roof systems carry 20+ years insurance backed guarantees.
3. Weather Resistant – Offers strong protection against UV rays, rain, and snow.
4. Cost-Effective – One of the most affordable roofing solutions.

Types of Felt Roofing Systems

1. Torch-On Felt Roofing
   • Applied using a gas torch to bond the felt layers securely.
   • Provides excellent waterproofing and durability.
   • Commonly consists of three layers: a perforated base layer, a reinforced middle layer, and a top cap sheet.
2. Self-Adhesive Felt Roofing
   • Eliminates the need for open flames, making it a safer option.
   • Features an adhesive backing that sticks directly to the surface.
3. Cold-Applied Felt Roofing
   • Uses bitumen-based adhesive instead of heat application.
   • Safer than torch-on systems, reducing fire hazards.
   • Suitable for areas where hot works are restricted.

Conclusion

Felt roofing systems remain a popular and cost-effective choice for waterproofing flat and low-pitched roofs. With various application methods available, including torch-on, self-adhesive, and cold-applied systems, felt roofing provides versatility, durability, and long-term protection when properly maintained.

Rio Asphalt are committed to Safe2Torch. It is an important initiative aimed at enhancing fire safety in roofing practices, particularly for whilst using torch-on felt roofing systems.

Key Aspects of Safe2Torch:

1. Purpose:
   • The initiative is designed to significantly reduce the risk of roof fires during the installation of torch-on roofing systems.
2. Collaboration:
   • Safe2Torch is a campaign developed by the National Federation of Roofing Contractors (NFRC) in partnership with roofing contractors and manufacturers. This collaboration ensures that the guidelines are practical and effective.
3. Guidance and Best Practices:
   • The program provides guidance on risk assessment and promotes safe working practices. This includes:
     • Specification writing at the initial survey and design stage.
     • Establishing a safe system of work when using torch-on methods.
4. Training and Resources:
   • Safe2Torch emphasizes the importance of training for contractors to ensure they are aware of the risks and the best practices to mitigate them. This includes understanding the materials used and the proper techniques for installation.
5. Fire Safety Guidelines:
   • The initiative includes detailed fire safety guidelines that help contractors and clients understand the necessary precautions to take during installation.

In summary, Safe2Torch is a proactive approach to ensuring that torch-on roofing installations are conducted safely, reducing the risk of fire and enhancing overall safety standards in the roofing industry.
