High performance felt

Roofing felt is a roll of base material which is coated and impregnated with unmodified and modified bitumen. This extremelty durable and high performance felt is a polyester based materials which will not split and is impregnated in modified bitumen. There are 2 main methods of applying felt; The first and original method is "Pour & Roll". This is where bitumen is melted in a bitumen boiler, often called a pot, then using a ladel put into pouring cans ready to be poured onto the roof surface so that the felt can be rolled into the flood of bitumen. The second method is "Torch-on". The felt is manufactured with a layer of modified bitumen applied to the underside of the felt, this is heated up and melted using a gas torch to form a "flood" of bitumen at the base of the roll just like pour & roll.
