Monday, 20th February 2017

EPDM rubber roofing from Firestone

As one of the upcoming and increasingly popular roofing options for trade and those who are wanting a straightforward roofing solution that they can do themselves, it is important you know what the pros and cons are when using EPDM on your roof.

Below we will go into some detail on the main advantages and disadvantages of using this option for your own project.


Pro: A LongLasting, low Maintenance Solution That Looks Good

EPDM roofing is leagues ahead of some older traditional flat roof material, such as felt for example. Rubber roofing is suitable for extreme conditions, giving you one of the most durable and reliable roofs available that typically lasts between 30-50 years.

In time, you may find a felt flat roof can pick up moss and algae; the synthetic rubber doesn’t support the growth of moss so you are guaranteed a clear roof! It also doesn’t easily show dirt, meaning less time spent for you up on the roof cleaning!

Con: Installation on Your Roof may not be Simple

Compared to an installation on a roof with obstacles such as lanterns, chimneys and vents, if you have a completely flat roof and x number of square meters, your installation will be relatively easy.

Obstacles, such as those listed above, require the rubber to be cut, flashing tape to be used and water-tightness must be kept throughout! In cases where your roof is not completely flat, it would be advisable to getting a professional to assist with the installation.

Pro: It’s Environmentally Friendly

The EPDM rubber roofing is made up of recycled materials, making it environmentally friendly compared to alternative roofing systems. The EPDM system is also BBA Certified, so you know that you are getting the best quality.

Con: Damage can Happen

So, while EPDM membranes are extremely durable, they are not indestructible; foot traffic and falling objects (such as tree branches and all sorts of things from the outside) can cause the membrane to tear. It is important to keep an eye on your roof to ensure any damage is spotted immediately so that it can be repaired back to waterproof standard.

The fact that the product can tear doesn’t mean it easily will. The best way to prevent your roof from picking up any wear and tear is to opt for the thicker membranes, however as you would expect, these do come at higher prices, so keep budget in mind!

Pro: If There is Damage, Repairing is Easy

  1. Clean the damaged surface thoroughly to ensure nothing will interrupt the bonding process for the rubber.
  1. Correctly prime the surface using the appropriate primer.
  1. Use your 9” flashing tape to completely cover the damage

Sometimes having the knowledge that even if damage were to happen you can perform a repair without too much stress and hassle can make all the difference, and that is one of the many things EPDM offers.

Con: Finding the Right Installer

Rubber roofing has been around for 40 years, which isn’t a long time compared to other roofing methods! As a result, finding an experienced roofer nearby to carry out your project may be harder than you think.

The best way for you to find a certified installer is to visit a manufacturer’s website or contact them directly. Many have thousands of professionals that have attended courses and have a good track record which they can share with you.

Pro: Custom Made for you – cut to Size Service

The EPDM membrane that we provide will be cut to specification to fit your roof, including the necessary overhang to ensure easy installation. The best way to specify the exact sizes is to call us on 01303 769 990, but you can also send these to us on a web order form by including your dimensions in the delivery note section.

Having the rubber roofing cut to size means you can get a standard roof done with one membrane. If you have a couple of pieces of membrane to join together, you will need to use the 5” Flashing Tape.

Pro: No Blistering, Cracking or Rotting!

Due to its natural properties, once installed, the rubber will be completely resistant to blistering, cracks, and any rot. This gives EPDM rubber roofing many further advantages to other types of flat roofing and gives you as the customer fewer things to worry about.

In Conclusion…

As you can see after going through our list, EPDM rubber roofing has more benefits than most other roofing methods. It is a strong, durable and resistant material which is easy to repair should damage happen. It is no wonder that this product is getting more and more popular with our shoppers.
