Torch-On
Rose Roofing offers a wide range of torch-applied systems. Whether, oxidised bitumen, SBS or APP modified. Rose Roofing has it covered.
Torch-on membranes have an underside of pre-treated thermofusible. This covering is then heated with a propane gas torch and the membrane is applied to the surface of the roof while the bitumen is still hot.
