EPDM roofing is becoming increasingly popular in both commercial and residential properties, find out more about the benefits and cost of EPDM here.

emdf roofing installation costThere are many homes in the UK that their food is either completely or partially flat. Even though this typeof roofing used to be popular in the past and might still be, it has many drawbacks. If you live in a house where more of the 40% of the total roofing area is flat, then you might have a hard time finding a standard insurance cover. However, thank to new technology, you do not have to worry more about having a flat roof, as EPDM has came to revolutionise the roofing market.

What is EPDM roofing?

What is the benefit of EPDM roofing?EPDM stands for Ethylene Propylene Diene Monomer; it’s a type of thermoset membrane. An EPDM roof is a single-ply rubber membrane, which is around 50mm in thickness and is normally used on flat roofs. You can buy it in rolls, which can be as wide as 50 feet, though most rubber roofs require much narrower EPDM materials. This type of roofing is usually black, although EPDM can have pigments or dyes added to it to make it lighter, which can help to keep the building cooler by reflecting the sun’s rays.

  • Like other rubber roofs, EPDM roofs are very lightweight.
  • EPDM is very easy to install.
  • It is very effective at keeping a roof watertight.
  • Has a very long lifespan.
  • EPDM roofs don’t need much maintenance.
  • It is a flexible material which can be installed on any type of roof whatever shape or design it is.
  • When roofs become damaged by punctures or tears, they can be patched up easily.

What are the disadvantages of EPDM roofing?

  • It has to be said, they are not the most aesthetically pleasing roofs.
  • Whilst you can do a DIY job, EPDM manufactures suggest professional installation, which can bump the cost up.
  • Changes in weather mean that rubber can crack or shrink.
  • Poor drainage systems can lead to the roof leaking.

How is EPDM installed?

EPDM is glued to the roof deck using special roofing adhesive. Mechanically fastened rubber roofs are then attached using nails to screw along any loose edges of the material. Loose-laid systems are fastened only around the perimeter and are coated with gravel to help weigh down the loose-laid sections. All rubber roofs including EPDM roofs are bonded together via a cold applied tape and primer system to ensure that they are watertight.

What sort of roof is EPDM best for?

EPDM rubber is best suited for flat or at least low-slope roofing structures. This is because it is bonded at the seams with heat, to create a continual barrier, meaning it is far more watertight then shingles or rolled roofing options. Rubber roofing also helps to protects houses from wind and other harsh forms of weather.

How Long does EPDM roofing takes?

It is difficult to estimate how much time it will take to install EPDM roofing as the length of the job will depend on several factors such as:

  • Preparation work.
  • Roofing firm size.
  • Accessibility (need for scaffolding).
  • Battens and beams replacement.

If you want to get a good understanding of how long the project will last, you will need to ask your roofer for a breakdown when quoting. Furthermore, plan roof replacement work can be done easier during the summer days, as the days are warmer, longer and brighter.

A small job such as a single storey extension usually take a day. Replacing a three bedroom house roof, takes nearly a week but if the beams and joists need replacing too, it could take as long as three weeks.

How much does EPDM roofing cost?

EPDM roofs are often criticised because they cost more than felt flat roofs, as EPDM is more expensive material on a per metre squared basis. Also, when you are replacing your roof, roofers will give you a quote based on the size of the roof, the labour, materials and the cost of scaffolding hire.

The cost of EPDM roof will also depend entirely on where you live and which roofer or roofing company you will choose. But roughly, you can expect to pay around £60-£80 per square meter for a professional roofer.

You can buy a EPDM kit yourself for around £600-£800, or you can buy just the EPDM material at around 8£ -£10 per square meter. Whilst it may be tempting to save money by doing the job yourself, think of the longevity of your roof, it will probably have a longer lifespan if fitted professionally.
