If you are a commercial building owner looking for an affordable roofing option for your flat or low-slope roof, a torch down roofing membrane might be a great choice. Torch down roofing takes its name from how it’s installed. Also called rolled roofing, this type of flat roof membrane can be found on commercial buildings across the U.S.
This guide to torch down roofing systems aims to help you decide whether this reliable roofing option is perfect for your flat roof. Read on to learn more.
What Is A Torch Down Roofing Membrane?
Torch down roofing membranes are one of the most effective yet affordable types of rolled roofing materials commonly found on low-slope or commercial flat roofs. These durable and thick roofing membranes are made of multiple layers, including thermo-fusible film, modified bitumen, polyester, and a waterproof surface.
Additionally, torch down roofing membranes are rolled out during the installation and then heated with an open flame so they adhere to the roof deck. This installation method ensures a water and air-tight seal around the corners, making membranes less susceptible to water and moisture damage. Moreover, torch down roofing systems are temperature resistant, as is evident from their installation method, making them an incredible roofing material for properties in high-heat areas. All torch down roofs are made of modified bitumen, but there are two main types for property owners to consider.
Two Main Types of Torch Down Roofing
When it comes to torch down roofing systems, property owners have the option to choose from two main types, each offering its own set of features and benefits.
1. Smooth Surface Torch Down Roofing
As the name suggests, a smooth surface torch down roof has no granules added to the top layer. Characterized by its sleek, flat appearance, smooth surface torch down roofing membranes offer a modern aesthetic. Moreover, it is relatively easy to clean and maintain. The absence of granules also means that smooth surface torch down roofing may be less prone to algae or moss growth over time.
2. Granulated Surface Torch Down Roofing
True to its name, granulated surface torch down roofing membranes come with granules added to its surface. Opposite to smooth surface torch down roofing, it features a textured surface. The granules embedded on top serve several purposes, including added protection against UV rays, enhanced roof durability, and improved traction for maintenance.

As said, the membranes are rolled out onto the roof deck with no additional tool required and then heated to create a watertight seams. Also, their flexibility allows them to adapt to the contours of low-slope roofs without compromising their integrity.

While the smooth or granulated surface options provide some variation, the overall appearance of torch down roofing may be more industrial than decorative.

Though torch down roofing is an affordable and cost-effective option, the installation price may vary regionally depending on certain considerations and labor costs.

Comparison To Other Flat Roofing Materials
In the competitive market of roofing materials, here is how torch down roofing systems stand compared to other options:
1. EPDM
EPDM is a widely known roofing material for flat or low-slope commercial roofs. Their affordability and durability make them stand out among the crowd. Along with being more cost-effective than torch down roofing membranes, EPDM is easier to install and upkeep compared to a torch down roof. Additionally, it sticks to the roof deck well, protecting it from water seepage, and it stands strong against UV rays and elements. However, torch down is lighter and more flexible compared to EPDM.
2. TPO
TPO is an incredible flat roofing solution for energy efficiency and heat reflectivity. While a torch down roofing membrane also provides some level of heat resistance, TPO may offer better thermal performance overall. Moreover, unlike torch down roofs, TPO is available in a variety of colors and thicknesses, allowing you to choose the durability level and style that best fits your needs. However, torch down roofing systems are more cost effective than TPO.
3. PVC
PVC is known for its exceptional chemical resistance properties, which make it a reliable roofing option in commercial and industrial settings. While torch down roofing membranes may also provide flat roof owners with chemical resistance, it may be less effective compared to PVC roofs. However, for property owners tight on budget, torch down roofs can be more effective because PVC is generally more costly and can require frequent maintenance.
