Flat Roofing Problems Prevented by EPDM

EPDM Rubber Roof

Flat roofing has many benefits, which is why it is used on residential and commercial roofs across the globe. Flat roofs help people save money, space and precious time. Not to mention the fact that they come with few downsides in comparison to pitched roofs.

There are many different types of flat roofing, some of which perform better than others, with some failing while others stand strong. Problems with flat roofs can be rare and are usually due to poor installation, poor maintenance or simply that the material used isn’t able to withstand everything.

At Avenir Roofing, we are experienced suppliers of Firestone EPDM RubberCover, a type of EPDM roofing that is high-performing and can prevent a number of problems experienced by other flat roofing systems. Benefits include:

  • 20-year warranty – Firestone offers a 20-year warranty on EPDM membrane because it is extremely durable and strong.
  • Installed in one piece – Firestone EPDM can usually be installed in one piece, making it a neat and tidy solution. This means no joins and no leaks.
  • Installed using cold adhesives – No heat is required, for easy installation.
  • Eco-friendly – Another one of the main advantages of Firestone EPDM is that it is eco-friendly. Its long lifespan means that it is more sustainable than other flat roofing types.
  • Doesn’t tear or split – Unlike other roofing membranes, Firestone RubberCover is extremely resistant and will not tear or split.

 

The many strengths of EPDM make it superior to other systems such as fibreglass, felt roofing or PVC. Here are a few of them:

Thermal Movement

Changes in temperature cause roofs to expand and contract. This is normal, but prolonged or excessive expansion and contraction can result in what is called thermal shock or thermal movement.

EPDM performs very well in these circumstances on both small and large roofs, whereas some roofing types such as fibreglass aren’t the best solution for large roofing areas because expansion and contraction rates can be excessive.

UV Resistance

It is important for flat roofs to not only resist wet weather but to also withstand UV rays from the sun. UV rays have an effect on roofs over time, and can even have an effect on overcast days, as the UV rays break through the clouds.

EPDM membrane resists UV rays exceptionally well, while systems such as felt roofing aren’t UV resistant and will break down over time.

Cost-Effectiveness

While some flat roofing systems appear cheaper than others, that doesn’t necessarily mean that they are cost-effective. Flat roofing systems with a longer lifespan are more cost-effective because they will not need replacing for longer, and require little to no repairs.

When compared to rubber roofing, GPR or fibreglass goes beyond the threshold to cost more money. But, there is cost flexibility according to the kind of finish you choose.

Vegetation

The growth of moss or algae can cause serious issues for roofs because it is usually caused by a build-up of moisture. It can also look quite unsightly, ruining the aesthetic of a building. EPDM does not support the growth of such vegetation, so this is an issue you don’t have to worry about.

No Joins or Seams

Another factor which makes EPDM superior to other flat roofing systems is that it can usually be installed in one piece. Felt roofing is usually joined every 1m, while PVC is heat welded and also joined every 1m-1.5m. Joins in flat roofing materials can become weak points, making the roof more vulnerable to leaks and damage.

Plus, both felt and PVC can fail due to poor installation. In contrast, EPDM is a flat roofing system that is much more simple and easy to install. Since most flat roofing types fail due to poor installation, EPDM does not have this issue.
EPDM has a multitude of benefits, all of which help you avoid common issues with other flat roofing materials. To learn more about it, visit the rest of our blog or take a look at our website.
