In the past, flat roofs were traditionally waterproofed by using bitumen based felt.  This type of roof costs less to buy and install and will probably serve you well for a couple of years.  However, it won’t be long before you are likely to have issues.

Felt is very susceptible to temperature changes and hot summers and cold winters can cause it to become brittle, blister and crack which means that rainwater cannot drain properly.  Instead it can pool and ultimately leak into your property’s roof structure and cause severe damage without you even noticing.  It can rot your deck and joists long before the problem is noticeable.

Traditional flat felt roofs have an average lifespan of 10 years and you will probably have to repair it a number of times before the decade is up.

Ethylene Propylene Diene Monomer (EPDM) rubber roofing has now firmly established itself as the most popular option for flat roofing of all sizes. The benefits it provides and its cost-effectiveness over a long-term period have seen it become the flat roofing system of choice for many property owners.

EPDM rubber and felt roofing systems are the most commonly used materials for residential homes in the UK. If you're still considering your options as to which one to use on your flat roof here is a short overview comparing the two materials.


• Durability: EPDM is a far more durable material in comparison to felt and can withstand the more extreme scales of weather across the year. Felt is more susceptible to blistering in hot climates and cracking in the cold. EPDM will not experience these same issues. Rubber roofing is also far more flexible which reduces the risk of leaks and is extremely easy to repair.

• Cost: Felt membranes are a cheaper alternative to EPDM but the difference in performance levels mean that rubber membranes offer much better value for money. This means EPDM is more cost-effective in the long run despite the initial higher costs of purchasing the material.

• Appearance: Felt doesn’t react well to the growth of algae or moss. The opposite is true of EPDM.



Environmentally Friendly EPDM


Ethylene Propylene Diene Monomer membranes are particularly suitable for the sort of extreme conditions commonly found in flat roof applications, making EPDM the most reliable and durable material solution for your flat roof.

Extremely ECO friendly materials are all applied with little energy - both the Government and the International Kyoto Ecology Agreement recommend EPDM rubber as best value sustainable eco-sound roofing. Whilst in a report entitled “Building For The Future”, international environmental agency, Greenpeace, put EPDM membranes at the top of their rankings of low impact membranes. This ranking was based on EPDM’s environmental sustainability due to its extended lifespan and re-usability.

EPDM membrane roofing is also ideal for providing a waterproof rubber roof coating required for green roofs with sedum plants forming the top layer.



Long Lasting EPDM



If you are looking for flat roof materials with long lasting ability, EPDM is your answer. EPDM or Ethylene Propylene Diene Monomer, to give it its full name, is a flat roofing material designed to be able to stand up to the most extreme conditions that a flat roof will face.

It is this durability that provides EPDM with long lasting ability.  We offer EPDM flat roof fitting which has a life expectancy in excess of 50 years.

With a reliable and durable construction and a permanently flexible design, this type of flat roofing material is made to be able to withstand all kinds of weather conditions, including extreme weather cycles, changing climates, plus protection from the acids found in rainwater and constant exposure to direct UV.

EPDM is different, is specifically designed as a flat roof material and it is installed in one piece with no overlapping. This means that rainwater will not be able to get beneath its surface. EPDM will also repel all moisture and “breathes” allowing vapours to escape thus preventing blisters. It is also highly resistant to UV (Ultraviolet light) and IR (Infrared light) and does not suffer with age from cracking or grazing.
