The Pros and Cons of EPDM Roofing

If you want to upgrade your old roof to a more durable, new finish, you may have considered EPDM. EPDM is a type of synthetic rubber that can provide a more energy efficient and durable material to replace a worn out, old roof. This increasingly popular material can offer a straightforward solution, but before you make a final purchase decision, it is important that you understand both the pros and cons of EPDM roofing.

The Pros

EPDM roofing offers some fantastic benefits in a variety of applications, particularly compared to other roofing materials. These include:

  • Long Lasting & Low Maintenance: EPDM is leaps and bounds ahead of many traditional roofing materials, such as felt. This rubber roofing can be used in extreme conditions to provide a reliable and durable roof that can last between thirty and fifty years. While felt flat roofs can accumulate moss and algae, synthetic rubber will not support moss growth, so you can avoid the problems of moss intrusion causing splitting and leaks.
  • A Greener Option: EPDM is made using recycled materials, which makes it a greener option compared to some alternative roofing materials. EPDM systems are also BBA Certified to provide assurance that the product is made to the highest quality standards.
  • Custom Solutions: EPDM membranes can be cut to the exact specifications for the fit of your roof, including the necessary overhang to facilitate an easy installation. Having your roofing material cut to size allows a standard roof to be installed with one piece of membrane to minimise the risks of leakage along seams.
  • Easy Damage Repair: Repairing any damage to a EPDM roof is very easy. The damaged surface will need to be thoroughly clean to prevent interruption of the bonding process. The surface will need to be primed before flashing tape is used to cover the damage completely. This can eliminate much of the stress of performing repairs.
  • No Cracking, Rotting or Blistering: Unlike many roofing materials, the natural properties of EPDM will mean that once installed, the product will be resistant to cracks, blistering and rotting completely.

The Cons

Although EPDM roofing can offer some fantastic benefits, you should be aware of the potential cons. These include:

  • Potential Complications: Unfortunately, the installation for your roof may not be straightforward and simple. If you have a completely flat roof with no obstacles, it is likely to be relatively easy, but this is not the typical scenario. Your roof is likely to have chimneys vents or even lanterns that will require the EPDM material to be cut to shape and then sealed with flashing tape to ensure water tightness. For this reason, it is vital to rely on an experienced professional who can perform a complete installation to eliminate the risk of leaks.
  • Potential for Damage: Although EPDM is exceptionally durable, it is not indestructible. Falling objects such as storm debris and tree branches or foot traffic have the potential to tear the membrane. While this can be easily repaired, it is crucial to watch out for any damage to ensure that your roof remains watertight. Additionally, although there is a potential for damage, you can reduce this risk by choosing a thicker membrane, but this will come at a higher price.
  • You Need the Right Installer: While rubber roofing has been around for decades, it is still a relatively new product compared to other materials. This means that you need the right installer to carry out your roofing project. Fortunately, our recommended professionals have vast experience in EPDM roofing to ensure that your roof is fully watertight and can protect your home for many years to come.
