Why Use Torch Down Roofing
The torch down roofing material is water-resistant, resistant to punctures, ultraviolet rays, and other damages. It requires minimal repairs and can last up to 20 years.
The rubbery additives in the roofing material allow it to expand and contract in extreme heat and cold. This makes it ideal for low-slope or flat roofs.
The roof protects against heat and UV rays. This helps lower your cooling bill during hot weather.
The heat-sealed seams and ultra-water proof membrane make the torch down roofing one of the most highly water-resistant roof systems. The roof prevents water from collecting and pooling on the roof and facilitates drainage. It also protects structures from damage caused by snow buildup.
The granulated cap layer is highly fire-resistant.
Repairing a torch down the roof is easy since the material can roll and be sealed quickly compared to other roofing materials.

What Is The Torch Down Roofing System
First, lets get into what exactly torch down roofing is. Torch down roofing is still one of the most commonly used roofing types for flat commercial roofs. The official name of this type of roofing is modified bitumen. It is a rolled roofing product that consists of a tough waterproof roof membrane embedded in a thick layer of asphalt. The rubbery additives with high-quality resins in the asphalt allow the roofing to expand and contract, whereas some other roofing systems would just crack. This roofing type can bond tightly to metal flashings and move them, while also maintaining the bond. This flexibility is the main benefit of modified bitumen and why it has been a success.
The reason why many property owners and local roofing contractors went with torch down roofing is that its impermeable to rainwater and is also resistant to otherwise damaging UV rays. The roofing would not melt or gather any large puddles of rainwater, so its already weatherproof to a good extent. Not only that its extremely durable because the combination of asphalt and resin makes it resistant to punctures and other damages. While all this is good, were going to talk about the negatives of torch down roofing and why it is dangerous.

Torch Down Roofing Poses Significant Fire Risks
When torching down a roof, it is so easy to make a mistake with the torch that could result in disaster. Consider roofers that are torching down a roof and they accidentally overheat something in the attic insulation, for instance. They end their work for the day, not noticing the smoke coming out of the soffit vents. Before long, that smoldering material in the attic heats up and starts a fire that quickly spreads throughout the dry, hot attic and then to the rest of the structure.
Almost every roofer and commercial roofing contractor you speak to that has experience in torch down roofing has some crazy tale to tell about it. It could be the serious injury of themselves or a colleague, or perhaps it nearly caused a serious fire at a property they were working on. The more you talk to roofers about it, the more you realize what an incredible risk you are taking every time you go out on a roof with flaming torches.

Torch Down Roofing With Modified Bitumentorch Down Rubber
Modified Bitumen Torch Down Roofing membranes were first developed in Europe in the mid-1960s, introduced in the U.S. in the late 1970s, and first manufactured in the U.S. in 1980.
The membrane is composed of various types of modifiers, reinforcements, and surface treatments.
The 36 inch-wide membrane comes with or without embedded ceramic granules that protect against harmful UV rays. The unprotected MB membrane needs an asphalt-aluminum coating, known as Silver Coating, for harmful UV protection.
Torch down roofing using MB installs as a single ply, or a two-ply membrane, on both commercial and residential buildings. When installed as a two-ply system, we provide a 40-year warranty.
Torch Down MB Over any Surfaces
The 2 Ply MB Torch Down Roofing Membrane is 3/8 thick and can be installed directly over an uneven stone surface without being compromised by punctures. In fact, the stone trapped between the membrane and the old roof provides excellent insulation.
Because these existing roofing systems can be covered with the 2 Ply MB, stripping and removing the current roof debris will not be an expense.
