What is Torch Down Roofing?

What is torch down roof? It is simply a newer technology that is used to strengthen roof structures by applying a waterproof membrane layer over the existing roof surface. If you wish to know what is torch down roofing, read this article and we will provide you more information. Torch down roofing is often called Grolle Down or Pitch Down roofing. It is not only used on residential roof structures but also commercial buildings such as office buildings, hotels and hospitals.

Torch down roofing consists of several modified bitumen membranes, usually applied with an industrial torch. This fastening process provides torch down roofing with a unique water tight seal, which makes it an excellent choice when water damage is an issue. The membrane applied over the roof surface is typically comprised of a high performance plastic like polystyrene and a thick epoxy resin-like liquid. These materials provide added strength, protection from ultraviolet (UV) degradation, chemical vapor compression, and abrasion. With its many advantages, this revolutionary roofing system can withstand extreme weather conditions, including sun, rain, hurricanes, snow and ice, which are part and parcel of most geographic locations.

It is important for consumers to understand that while this roofing material does have numerous advantages, there are some disadvantages as well. One of the major disadvantages of using this particular roof application is that it is quite slow to install. Roofing professionals usually apply this type of roofing material around a quarter of an inch or less. When fully installed, it can be installed in about five to six hours’ time. Moreover, since it is applied using a flame, there are some flammable liquids that can be released during the roofing application which could potentially be hazardous to the environment.

The main disadvantage of using this particular material is that it contains a very high degree of friction which makes it susceptible to thermal damage at elevated temperatures. The increased friction leads to a reduction in the life of the roof after it experiences temperatures of over 500 degrees Fahrenheit. Another disadvantage of using torch down systems is that they tend to damage the structure’s insulation because of the high temperatures they can reach. Subs, layers, and clapboard could be badly damaged due to increased temperatures.

The installation of this type of roofing material involves the application of a flame retardant layer on both the top surface of the membrane and the bottom surface of the underlying concrete slab. The membrane layers are composed of two types of materials. The first type is fire retardant or FR-rated and is commonly used on commercial buildings. The second type is specially made from zinc and is called low-flammability FR-Zn. The reason why the latter is referred to as low-flammability is because it contains no fire retardants, but is still capable of withstanding temperatures of up to 500 degrees Fahrenheit. Installation of this type of roofing material is usually done by specialized metal workers.

The installation of these roof systems require adherence to building codes, which specify the specific specifications for the particular roof system. Only after this step is complete can the final two-layer torch system (FR-Zn) be applied. There are three main methods for application of this material. The first involves spreading the roofing material into straight strips and fitting them together by welding. The second method involves embedding the insulation into the roofing material and pushing the sheets into place with hammers.
