Iconic Cladding offers a comprehensive roofing package which can include membrane roofing. The most common of which are Butyl, a budget membrane, glued to a ply substrate with a lapped tape join. TPO is also glued to the substrate but then heat welded at the laps with direct localised heat. It offers potentially greater durability and a more built proof system if installed well.
Torch On membranes are often two or three layers of bituminous membranes heated by naked flame gas torches which fuses the layers together forming an homogeneous layer. They have their place but we would not use Torch On products in refurbishment work due to the risk of fire.
