Self-Adhering Roof Membrane vs. Torch Down Roof Membrane


When it comes to roofing systems, choosing the right membrane is crucial for ensuring a durable and weather-resistant structure. In this blog, we will delve into the key differences between two popular roofing membrane options: self-adhering roof membrane and torch down roof membrane. We will explore their respective benefits, applications, and considerations to help you make an informed decision for your roofing needs.

1. Self-Adhering Roof Membrane:

Self-adhering roof membranes, also known as self-adhesive or peel-and-stick membranes, have gained popularity in recent years due to their ease of installation and versatility. These membranes consist of a rubberized asphalt compound with a peel-off backing, making them quick and straightforward to apply.


a. Easy Installation: Self-adhering membranes eliminate the need for torches and open flames during installation, reducing safety risks and the need for specialized labor.

b. Versatility: These membranes can be used on various roofing surfaces, including flat and sloped roofs, making them suitable for different architectural designs.

c. Self-Sealing: The adhesive properties of these membranes ensure strong adhesion to the roof surface, creating a watertight seal that minimizes the risk of leaks.


a. Temperature Sensitivity: Self-adhering membranes may require specific temperature conditions for proper installation. Extremely cold or hot weather might impact their adhesion properties.

b. Puncture Vulnerability: Though self-adhering membranes offer excellent waterproofing, they can be more susceptible to punctures during installation or due to foot traffic.

2. Torch Down Roof Membrane:

Torch down roof membranes, also known as modified bitumen roofing, have been a go-to option for flat and low-sloped roofs for several decades. These membranes are made from bitumen, which is reinforced with polyester or fiberglass materials.


a. Durability: Torch down membranes are known for their resilience and ability to withstand harsh weather conditions, making them suitable for long-lasting roofing solutions.

b. Superior Strength: The torch-applied installation method creates a strong bond between the membrane and the roof substrate, enhancing overall stability and wind uplift resistance.

c. UV Resistance: Torch down membranes typically have better resistance to UV radiation, reducing the risk of premature degradation.


In conclusion, both self-adhering roof membranes and torch down roof membranes have distinct advantages and considerations. If you prioritize easy installation, versatility, and self-sealing properties, self-adhering membranes may be the ideal choice. On the other hand, if durability, strength, and UV resistance are your primary concerns, torch down membranes may suit your needs better.
