Installation of rubber roofing is a straightforward process that requires roofing adhesive, mechanical attachments, or ballasting. Also, installations allow the sheets to overlay, allowing them to play the role of insulation and air seal.

Besides being affordable and the fact that it is easy to install, it’s a product designed with high Ultraviolet rays tolerance and cannot get corroded.

EPDM Energy Efficiency

Like most roofs, it’s essential to consider the energy efficiency of EPDM roofing. Look at it separately since it is the most significant offer a roof brings. Energy efficiency for rubber roofing is relative to location and the color you choose.

Although EPDM is available in black and white, black it’s the most common color. A white rubber roof could work for you if you live in warmer weather. Black typically absorbs more heat.

EPDM roofing has a lifespan of at least 40 years. It’s a long period considering that other single-ply roofs start to wear off sooner due to exposure to the elements. Proper installation is necessary to ensure the roof serves you long.

Rubber roofing can withstand strong winds and is impervious to UV rays. Improvements during the manufacturing process have made this possible.


A significant percentage of the materials used to make EPDM roofing are recycled. Producing rubber roofing also requires little energy because most raw materials are recycled.

Your energy cost is also lower when you have rubber that corresponds with your weather, which affects the environment positively.

It is Quite Unpleasant to Look at

Age tends to get better the aesthetic properties of EPDM roofing. Dust and other contaminants are the primary cause of the changes in their appearance.

You have the choice to dismiss the issue as it is superficial and doesn’t affect its functionality. If dismissal is not an option, scheduling regular cleaning can improve the look.

Seams Wear Out over Time

As much as the adhesive used to bind the seams of rubber roofing is strong, it tends to dry out and weaken over time. Lack of proper installation and shrinkage can also cause the seams to malfunction.

Once the adhesive wears out, it creates penetrations where moisture maul gets into the roof’s cavity. Consider scheduling routine maintenance to stay ahead of this issue.

Experiences Shrinkage

EPDM can quickly shrink as the membrane separates along the seams, parapet walls, and penetrations. It would happen if the installation of the rubber roof were poor.


Weather issues such as hailstorms and foot traffic can cause damage or rubber offing. An older roof is particularly fragile, and this factor will only damage the roof further.

EPDM roofing is quite effective; otherwise, it wouldn’t be in circulation along with other roofing materials. There are plenty of benefits to EPDM roofing, such as its durability. Such qualities should encourage you all the more to consider rubber roofing.

As a house owner, you have the final say on whether you can overlook the cons of rubber roofing or not. Consider consulting roofing experts to help you plan the best cost-effective move for you.
