What is EPDM Roofing? How is it Different from TPO Roofing?

“It is highly recommended to seek professional help from reliable and well-reputed roofer if you want to install EPMD roofing.”


The type of roof you have at your home or work place makes a huge difference. Most commercial places have flat roofs due to which it is very important not to compromise on the quality of the roofing. A good quality roof is leak proof, energy efficient, durable, low maintenance and economic. The best solutions that are recommended for flat roofing are Ethylene propylene diene monomer (EPDM) and thermoplastic olefin (TPO).

EPDM roofing consists of a synthetic rubber surface which makes it long-lasting and easy to install. EPDM roofing material is made from oil and natural gas which takes the form of black rubber-like substance. Due to this EDPM roof coating is installed in form of sheets. EPDM membrane is evenly rolled and folded back to apply adhesive to guarantee a good seal. EDPM rubber roofing is installed seamlessly and has no leaks, making it last a very long time. As the EDPM roofing material is synthetic rubber it can with stand high temperatures and is also fire proof.

On the other hand Thermoplastic polyolefin (TPO), is a layer of a single-ply reflective membrane that acts as a combination of polypropylene and ethylene-propylene. TPO rubber provides flexible and weather resistant characteristics. The main disadvantages of TPO roofing is that with the period of time, they become less flexible and form cracks on the surface. This is the main factor that compromises their durability and limits their lifespan. TPO roofs are usually welded, which complicates its installation and any repairs which might become necessary for TPO systems are harder to implement.

EPDM roofing is beneficial in several ways, when it comes to comparing the cost between the two, EPDM roof coating is the most economical solution. It tends to be much cheaper in terms of material and labor costs for single ply roof coating.

EPDM roofing are much more durable and can last for multiple decades. It can withstand most of environmental conditions that cause roofing materials to become brittle and crack over time. It has been observed that TPO is unable to withstand pooling water as compared to EPDM roofing material, and also that TPO does not perform as well in cold climates the way EPDM does.

In terms of maintenance, EDPM rubber roofing is much easier to maintain, even if it need repairs, they are very easy to do. TPO on the other hand, is hard to repair, and may have to be replaced altogether. EPDM membrane can be installed very quickly, and requires no special equipment. It just takes a skilled labor to ensure that the material is smoothly laid out and adhered properly on to the surface, and that’s it.

TPO requires a welding process to be installed, and can take quite a bit longer. The manufacturing process of EPDM is very energy efficient and the material used is fully recyclable. Therefore not only does the roof lasts a lifetime, but the material can be easily reused, making this roof material a favorite among ecofriendly homes and businesses looking to go green.

When it comes to decide which roofing is more suitable for your building, your choice should completely rely upon your geographic location, you should take into account the amount of rain, hail, snow and heat that your area receives and other external factors like the load the roof has to bear. But overall, EPDM rubber roofing offers more advantages over TPO in terms of cost, durability, maintenance.
