While we don’t install torch on felt or rubber roofing they can be relatively cheaper than a grp roofing. However, they don’t have the same life expectancy than fibreglass grp roofing, nor the security and durability. So it is a good idea to know the benefits and pitfalls of these types of roofing materials before making a decision.


Torch on felt- While cheaper than rubber or GRP flat roofing replacement materials, this method of roofing requires the use of powerful propane torches and this poses a substantial health and fire risk. Lifespan can be as little as 15 years and is completely non-recyclable so it will end up in the local landfill.

Rubber roofs do provide a waterproof membrane but are not suitable to be walked upon as the membrane could be torn. They are also susceptible shrinkage and wrinkles if tolerances during installation were not adhered to. These wrinkles can affect the waterproofing effectiveness if they occur where the rubber is overlapped.

A finished GRP Roofing system has a hardwearing impact resistant surface. When it is installed it is moulded around edging and obstacles, creating a watertight seal. GRP laminate is applied on over quality OSB3 deck. The roof is finished with GRP edge trims and a coat of colour topcoat. The durability and waterproof properties of GRP make it the ideal construction material for flat roofing. As well as being a lightweight material, it is robust, flexible and will never corrode.
