Torched Roofing: A Comprehensive Guide to Installation and Maintenance

Torched roofing, also known as torch-down roofing, is a popular roofing solution for both residential and commercial buildings. It is a type of modified bitumen roofing that is applied with a torch to create a durable and waterproof membrane. This roofing system has gained popularity due to its affordability, durability, and ease of installation.

The process of torching the roofing material involves heating up a roll of modified bitumen roofing with a propane torch. The roofing material is then rolled out onto the roof surface, and the torch is used to melt the asphalt on the back of the roll, creating a bond with the roof surface. This creates a seamless and waterproof membrane that is resistant to water, wind, and UV rays.

Despite its popularity, torch down roofing is not suitable for all types of roofs. It is best suited for flat or low-slope roofs, as it does not work well on steep roofs. Additionally, it should only be installed by a professional roofing contractor who has experience with torch down roofing. Overall, torch down roofing is a reliable and cost-effective roofing solution that can provide long-lasting protection for your home or business.

  • Use a propane torch with a self-igniting trigger.
  • Keep a fire extinguisher nearby.
  • Do not use the torch near flammable materials.
  • Work with a partner to ensure safety.

By following these basic materials and tools and safety precautions, one can successfully perform torched roofing and achieve a durable and long-lasting flat roof.

Installation and Techniques

Preparation

Before installing torched roofing, it is important to ensure that the roof deck is clean, dry, and free of any debris. The surface should be smooth and free of any bumps or irregularities. Any damaged or rotten wood should be replaced before installation.

In addition, it is important to install a proper underlayment to provide additional protection against water infiltration. The underlayment should be installed in accordance with the manufacturer’s instructions, and all seams should be properly sealed.

Application Process

The torched roofing material is applied using a propane torch. The installer must have experience and training in the proper use of the torch to avoid any safety hazards.

The roofing material is rolled out onto the roof deck and cut to size. The material is then heated with the torch and applied to the roof deck. The installer must ensure that the material is properly bonded to the roof deck and that there are no air pockets or gaps.

The roofing material is overlapped to provide additional protection against water infiltration. The amount of overlap will depend on the manufacturer’s instructions and the pitch of the roof.

Finishing Touches

Once the torched roofing material is installed, the installer must ensure that all edges and seams are properly sealed. This will provide additional protection against water infiltration.

In addition, the installer must ensure that all flashings are properly installed and sealed. Flashings are used to seal the roof around any protrusions, such as chimneys or vent pipes.

Overall, torched roofing provides a durable and long-lasting roofing solution. With proper installation techniques and regular maintenance, torched roofing can provide many years of reliable service.
