RubberBond Flat Roofing Durability Tests

Puncture tests When you are looking for the best materials to use, it helps to see proof of which direction you should be heading. In the case of EPDM flat roofs, that evidence – happily – exists for all to see.

No matter why you are looking into EPDM flat roofs – whether you are an architect looking for the most sustainable option or a homeowner seeking the toughest product – the goal must be to see how much extra value you get by opting for a premium product like this.

In a video released by RubberBond you can see in a durability test how the strength of RubberBond FleeceBack EPDM roofing outperforms an equivalent piece of SBS modified bitumen by a country mile. In reality, the RubberBond product fared 167 per cent better than its rival – and the impact on it’s longevity as a roofing material is plain to see.


The fact is that you do not need your roofing material to be all singing, all dancing in order to for it to be the best option – you need it to do two things well: keep out moisture and retain its performance with minimal maintenance. For that reason, EPDM has been a hugely popular choice for over half a century.

Whereas homeowners using DIY products will tend to have to get their roofs repaired or replaced within a matter of years, EPDM has a far longer lifetime. Part of what makes it more durable is that larger membrane sizes mean there are fewer joins – it is the seams and joins where conventional roofing systems start to get brittle over time and let in water.

In the case of RubberBond’s FleeceBack system, the membrane has Factory Applied Tape seams at the edge of the membrane- this makes it jointing stronger, less reliant on labour and gives your roof greater protection.

So what does the video at the top really show? After all, the scientific conditions appearing in the video are not going to actually happen in real life!

In layman’s terms, the puncture test tells you how much force in a concentrated area the material can put up with before it tears. The reason why this is so important is because debris (both man-made and natural) combined with high winds and other weathering can see your roof tested in this exact way. By installing a roof that will withstand much greater force, you are investing in your property’s ability to stand the test of time…
