If you are thinking of resurfacing a flat roof, you might have heard of EPDM rubber roofing. But, you may ask, what is it and why might it be an ideal choice for your roof?

EPDM stands for Ethylene Propylene Diene Monomer, which may not mean much to most people, but the fact that it isn’t just plain ‘rubber’ may hint at the fact that it is synthetic. That means it has been custom-designed, specifically for tough environments such as the various things that the capricious British climate can throw at it.

This is the key difference between EPDM and natural rubber. The latter, exposed at various times to heat, bright sunshine, rain, snow, frost and ice, will gradually wear and deteriorate.

Why Is EPDM Suitable For All Conditions?

However, EPDM does not do that because its various component chemicals give it extra strength, flexibility and durability. This adds to its excellent waterproofing qualities to make it perfect for a flat roof.

Indeed, EPDM can also handle many acids and alkaline substances, which may be useful if you are planning a rooftop garden. It also copes with alcohol exposure, should you have a seat up there on a nice summer’s day and spill your drink.

The only sorts of chemicals it doesn’t handle well are petroleum-based products, like any rubber, but that should be no issue, as you won’t be parking your car up there.

EPDM has been in popular use since the 1960s, which means it is not a new invention, but is also something that has proven itself over the decades to be a very reliable choice for roofing.

It can be fitted at any time and it may be a useful addition now, ahead of winter. But the best thing about this superb material is that it will serve your roof extremely well through all weathers for many years to come.
