If you’re considering a career in the roofing industry, it’s essential to familiarize yourself with various roofing materials and techniques. One such technique that has gained popularity in recent years is torch down roofing. In this guide, we’ll delve into what is torch down roofing, its benefits, installation process, and why it’s a valuable skill for aspiring roofing professionals. Let’s get started.
What is Torch Down Roofing?
Torch down roofing, also known as modified bitumen roofing, is a type of roofing material commonly used for flat or low-slope roofs. It consists of layers of asphalt-based materials reinforced with fiberglass or polyester fibers. The term “torch down” refers to the installation process, which involves heating the bottom side of the material with a torch to create a watertight seal.
Benefits of Torch Down Roofing
One of the primary advantages of torch down roofing is its durability. The multiple layers of asphalt and reinforcement provide excellent resistance to weathering, punctures, and UV rays, making it suitable for long-term use. Additionally, torch down roofing is highly resistant to water penetration, reducing the risk of leaks and water damage.
Another benefit is its flexibility. Torch down roofing can easily adapt to the movement of the building structure, making it ideal for areas prone to temperature fluctuations or settling. Its flexibility also allows for easy repairs and maintenance, extending the lifespan of the roof.
How to Install Torch Down Roofing
The following are the steps that you should follow to install torch down roof.
Surface Preparation
Before beginning the installation process, it’s crucial to prepare the roof surface properly. This involves removing any existing roofing materials, debris, and dirt. Additionally, any damaged areas of the roof should be repaired to ensure a smooth and even surface. Once the roof surface is clean and dry, it’s ready for the installation of the torch down roofing system.
Base Layer Application
The first step in installing torch down roofing is applying the base layer. This layer serves as the foundation for the roofing system and provides additional waterproofing protection.
The base layer is typically made of modified bitumen, which is rolled out onto the roof surface and secured in place using mechanical fasteners or adhesive. Care must be taken to ensure that the base layer is installed smoothly and evenly, with no wrinkles or bubbles.
Torch Down Material Application
Once the base layer is in place, the torch down material is applied. This material consists of layers of modified bitumen reinforced with fiberglass or polyester fibers. The rolls of torch down material are rolled out onto the roof surface, starting from one edge and working towards the other. Each roll should overlap the previous one by several inches to ensure a watertight seal.
As the material is rolled out, a roofing torch is used to heat the underside, melting the asphalt and creating a bond with the substrate. Care must be taken to avoid overheating the material, as this can lead to damage or fire hazards.
Sealing Seams and Edges
Once the torch down material is applied, any seams or edges must be sealed to prevent water penetration. This is typically done using a handheld roofing torch to heat the material and create a watertight seal.
Special attention should be paid to areas where two pieces of material overlap, as well as around roof penetrations such as vents, chimneys, and skylights. Properly sealing these areas is essential for ensuring the long-term performance of the roofing system.
Flashing Installation
In addition to sealing seams and edges, flashing is installed to provide extra protection against water infiltration at vulnerable areas of the roof, such as valleys, eaves, and roof penetrations.
Flashing is typically made of metal or another durable material and is installed using mechanical fasteners or adhesive. It’s important to ensure that flashing is installed correctly and securely to prevent water leaks and other issues.
Quality Inspection
Once the torch down roofing system is installed, the entire roof should be inspected for any defects, wrinkles, or other issues that may affect its performance. Any necessary repairs or adjustments should be made promptly to ensure the integrity of the roofing system. Additionally, the roof should be inspected regularly as part of routine maintenance to identify and address any potential problems before they escalate.
Why Torch Down Roofing is a Valuable Skill
For aspiring roofing professionals, mastering the technique of torch down roofing can open up a world of opportunities. With its growing popularity in both residential and commercial applications, there is a high demand for skilled workers who can install and maintain torch down roofing systems.
