Torch down roofing, an innovation in modern building design, offers both functionality and durability. By merging tried-and-true roofing materials with contemporary application methods, torch down systems provide solutions for various roofing needs. In this article, we’ll delve deep into the what, why, and how of torch down roofing systems.

1. What is Torch Down Roofing?

Torch down roofing is a type of modified bitumen roofing. The “torch down” process involves applying sheets of modified bitumen (a mixture of asphalt and synthetic rubber) using an open flame torch to melt the material, ensuring a seamless and adherent layer on the roof.

2. Components of Torch Down Roofing

  • Modified Bitumen: This is the primary material in torch down roofing. Modified bitumen sheets have a blend of asphalt and rubber components, providing both flexibility and robustness.
  • Base Sheets: Beneath the modified bitumen lies the base sheet layer, which offers an additional layer of protection and often acts as a secondary waterproof barrier.

3. Advantages of Torch Down Roofing

  • Durability: One of the primary benefits is its durability. Properly installed and maintained torch down roofs can last up to 20 years, making them a long-term investment.
  • Water Resistance: Torch down roofing provides an excellent watertight seal, ensuring protection against leaks and water damage.
  • UV Protection: Many torch down materials come with a reflective surface, protecting the building from harmful UV rays and helping in temperature regulation.
  • Fire Resistance: Interestingly, while an open flame is used in its installation, torch down roofing is resistant to fires.

4. Installation Considerations

  • Professional Requirement: The installation involves open flames, making it a risky endeavor for the untrained. It’s essential to hire professionals with experience in torch down roofing installation.
  • Weather Conditions: The application is best done in mild to warm weather. Cold or damp conditions can affect the efficiency and quality of the installation.

5. Maintenance and Care

Though torch down roofs are durable, occasional inspections are crucial. Look for signs of wear, such as cracks or blisters. Regular maintenance can extend the roof’s lifespan and ensure it functions optimally.

6. Cost Implications

While torch down roofing might have a higher upfront cost compared to some other roofing types, its durability and low maintenance requirements often make it a cost-effective solution in the long run.


Torch down roofing systems, with their blend of traditional materials and modern application techniques, offer a resilient solution for many buildings. When considering this option, always consult with roofing professionals to ensure a safe and efficient installation.
