Bitumen has been used in flat roofing for a long time because of its longevity and durability. Bitumen, however, is a by product of oil production, usually made from petroleum. With roofing companies looking to the future and at how they can produce roofing membrane using less toxic and environmentally damaging materials, with some producers of roofing materials claiming the future of the industry may be in the development of a 100% biobased roofing membrane which recreates all the same technical and functional characteristics of bitumen.

Bitumen has long been influenced by fluctuating oil prices. With oil costs set to rise further due to the demand and difficulty in processing fossil-based fuels, renewable and more affordable resources have been boosted to the top of roofing companies lists in order to be affordable to their clients.

A non-profit organisation in Netherlands, TNO, have found that integrating Lignin, a component of plant biomatter, with bitumen at a molecular level rather than simply mixing the two together could reduce the amount of bitumen required by as much as 50% – a positive start in developing a better environmental profile.

Roofing materials using biobased ingredients can also be specially designed for warmer and cooler weather conditions by using different amounts in their formulations to prevent the material from becoming too tacky or brittle.

Here at valent roofing, our industrial roofs are specially designed for each building and we are looking to the future of the business to make sure the materials we use are the best quality, especially from materials produced using biobased foundations that can help reduce the requirements for fossil based materials such as bitumen.
