It can be used as a single-ply or dual-ply system. Torch Down roofing gained popularity for its affordability compared to hot tar roofing.

Torch Down Roofing: Understanding the Materials

When it comes to torch down roofing, it’s important to understand the materials involved. While it may be commonly referred to as a “rubberoid” roof, this term can be misleading. Torch down roofing is actually made from modified bitumen, which is a type of asphalt that has been mixed with additives for enhanced performance.

There are two main types of torch down roofing membranes: Atactic Polypropylene (APP) and Styrene Butadiene Styrene (SBS).

Atactic Polypropylene (APP) Roofing Membrane: APP is a form of plastic that is added to the bitumen during manufacturing. This polymer enhances the flexibility of the torch down roofing membrane and allows it to withstand heating and cooling cycles effectively. APP membranes can be installed using torch application or alternative methods such as self-adhesion, cold processing, or mopping.

Styrene Butadiene Styrene (SBS) Roofing Membrane: SBS is a type of rubber that is also added to the bitumen to create modified bitumen roofing material. Compared to APP, SBS offers even greater flexibility and has a lower melting point. SBS modified bitumen membranes can be installed using torch application or other methods like self-adhesion, cold processing, or mopping.

Both APP and SBS torch down roofing membranes often incorporate a sturdy core material such as fiberglass or polyester mat. This core provides strength and stability to the membrane. Additionally, manufacturers may embed small granules on the top surface of the membrane to enhance fire resistance, offer color options, provide UV radiation protection, or introduce other distinctive characteristics.

By understanding the components of torch down roofing, you can make informed decisions about your roofing needs and choose the right materials for your project.

Types of Torch Down Roofing Systems for Commercial Buildings

When it comes to flat roofs on commercial buildings, torch down roll roofing is a popular choice. There are two main types of torch down systems: two-layer systems and three-layer systems. Both systems consist of a base sheet and a cap sheet. However, in the three-layer system, an additional granule cap sheet is applied to enhance the roof’s longevity and provide added benefits such as fire resistance, energy efficiency, and aesthetic features.

Let’s take a closer look at the components that make up torch down roofing systems:

Insulation: Flat or low-slope roofs require insulation to retain heat in the building. Insulation is applied first, either mechanically attached with screws and plates or fully adhered with glue or a hot mop, depending on the deck type and performance requirements.

Vapor Barrier: A vapor barrier is applied next to prevent condensation or moisture issues within the roof structure.

Overlay Board: An overlay board or cover board is laid down to provide support for the torch down roofing membrane. Proper application of the overlay board is essential to prevent water pooling and ensure a level roof surface.

Base Sheet: The base sheet is the first layer of modified bitumen membrane. It can be securely attached to the overlay board using methods such as direct heat fusing, hot mopping, or adhesive.

Cap Sheet: The cap sheet is the top membrane layer in a torch down roofing system. It is rolled out, and a roofing professional uses a torch to heat the bottom of the cap sheet and the top of the base sheet. This heating process creates a strong seal between the layers. In a two-layer system, the process is complete at this stage. However, in a three-layer system, an additional granule cap sheet is applied using the same method.

Flashing for Penetrations: To ensure waterproofing around roof penetrations like vents or HVAC units, a self-adhering modified bitumen membrane is typically used as flashing. Metal flashing is then applied above the self-adhering membrane, with the metal being primed to enhance adhesion.

By understanding the components of torch down roofing systems, you can make informed decisions about your commercial roofing needs and ensure a durable and reliable roofing solution.

Differences Between Torch Down and Hot Mopped Roofing Systems

When it comes to roofing options, building owners often face a choice between torch down and hot mopped roofing systems, also known as Built-Up Roofing (BUR). Understanding the differences between these two methods can help in making an informed decision. Let’s explore the distinctions:

Torch Down Roofing: With torch down roofing, the installation involves laying down base and felt layers, followed by using a torch to heat and melt the modified bitumen membrane. This creates a strong bond between the layers, resulting in a waterproof and durable roof.

Hot Mopped Roofing (BUR): Hot mopped roofing gets its name from the installation process. It involves pouring liquid asphalt onto the roof and using a mop to evenly spread it out. As the asphalt cools and hardens, it forms a thick, waterproof, and durable rooftop.

Performance and Characteristics:

Lifespan: Both torch down and hot mopped roofing systems have similar lifespans when properly maintained.

Puncture and UV Resistance: Torch down roofing systems generally offer better puncture and UV resistance compared to hot mopped systems.

Cost: Hot mopped roofing systems are often less expensive to install compared to torch down systems.

Safety Considerations:

Fumes and Exposure: During the installation of a hot mopped roof, roofing professionals are exposed to fumes for a longer duration. Proper precautions should be taken to ensure their safety and minimize exposure.

Ultimately, the choice between torch down and hot mopped roofing systems depends on factors such as budget, specific requirements, and the expertise of roofing professionals.

Ideal Roof Situations for Torch Down Roofing - AZ Roofing

Torch down roofing systems are well-suited for specific roof situations, particularly in large commercial buildings with flat or slightly pitched roofs. Here’s when torch down roofing is an ideal choice:

Slightly Pitched Roofs: Torch down roofing is best suited for roofs with a slight pitch, typically ranging from ¼:12 to 1:12. These roofs require a durable and long-lasting solution that can withstand various weather conditions, including heavy snow.

Commercial Buildings: Torch down roofing is commonly used in large commercial flat roofs due to its durability and resistance to the elements.

Climate Adaptability: Torch down roofs are designed to expand and contract without melting or cracking, making them suitable for all climates. They provide excellent water resistance and can withstand extreme temperatures.

It’s important to note that torch down roofing is not typically recommended for completely flat roofs.

I had a hard time finding a roofing company to inspect my 4-story townhouse, but these guys did it with a drone! Not only that but they found that it was my attached neighbours who had the problem with falling shingles and mine were secure. I am so happy I went with this company for the peace of mind, and they were honest enough to tell me that my shingles were good. If you want to deal with professionals who find solutions not just more problems – this is the right place.
