A Guide to Torch on Roofing This method of roofing involves a flat roof covering
being applied by method of welding, effectively melting the material to a
surface and creating an impenetrable waterproof seal. Building regulations
require three layers of felt to be used for habitable areas of homes, and this
method is advised to be used only by professionals due to obvious safety risks.

Where Is It Used? This method is one of great versatility and can be applied
to numerous surfaces including concrete and timber, allowing it to be used for
a range of buildings from residential buildings to larger more commercial
buildings. This makes it very common place due to the wide range of buildings
in which it is an eligible option for.
If the project is a reparation of an existing flat roof, you
can simply felt over the existing material already applied as long as the
materials have held up enough to warrant this. If the materials are not in a
decent condition however, the best course would be to fully replace them.
The Benefits For experienced roofers, the quick application time of this
product alone makes it a more than viable option, as well as its ability to be
applied in both wet and dry conditions. Due to the spontaneous nature of
British weather this is one advantage it has over alternative flat roof
options.
The materials reliability stems from its strong resistance
to UV rays, strong winds and rain, with the mineral finish of the felt breaking
up sun rays as they hit the material which stops the bitumen from melting. Particularly
relevant in the midst of hot summers, this keeps the temperatures within the
applications cool.
The Structure All types of torch down roofing are made from modified
bitumen, also known as asphalt, which is also used for paving, hence its high
levels of durability. However, in order for bitumen to be suitable for use as a
roofing material, it must first be mixed with a polymer.
The core of this material usually consists of a sturdy
material such as polyester or fibreglass, providing solidarity and durability.
Fire resistance is achieved by embedding small granules into the top of the
membrane.
Things to Consider It is always recommended to have a professional install this
particular type of roofing, mostly due to the clear fire hazard brought about
by the method of installation. The safety training professionals have received
has reduced the rate these accidents occur greatly.
It is also possible for the seams to fail and leak if they
are not properly installed, another issue made less likely if you seek a
trained professional. Water may get trapped within the material and lead to
long term water damage if not adequately installed.
