Do you think that the EPDM roof of your house is the strongest part of the building? And, can it easily sustain strong sun, heavy rains, and sudden storms? Well, EPDM roofing membranes are famous for their resilience- but they also have an expiry date.
Quick answer: According to some EPDM membrane roofing suppliers, EPDM membrane roofing can last up to 30 years with proper maintenance. In some places, we have seen it lasting even longer. But, how do you know that the EPDM membrane roofing price you are paying is justified?
‘How long can EPDM membrane roofing last?’ is one of the most common questions of buyers. Is there really a way to predict the future of the roofing membranes? Especially with temperature and climatic variations?
Let’s find out what some of the top EPDM roofing membrane manufacturers have to say:
What are EPDM roofing membranes made of?
The EPDM Roofing Association defines EPDM membranes as a synthetic product that is extremely durable. It is made of Ethylene and Propylene- both are derived from oil and natural gas.
EPDM membrane roofing comes in standard black, grey, and white colors in different sizes.
5 Things that Quickly Degrade EPDM Roofing Membranes
Several studies have concluded that the EPDM membrane roof system is more reliable than other roofing materials. However, no matter the EPDM membrane price you are paying for, these 5 things can degrade them quickly:
1. EPDM Membrane Roofing Installation Quality
EPDM roofing membranes can be installed quickly and require minimal equipment to do so. This is where most people go wrong. Poor installation of EPDM rubber waterproofing membrane is the #1 reason behind its quick degradation.
Key aspects like seam sealing, flashing, and substrate preparation must meet manufacturer and industry standards. Therefore, it is better to consult with a professional. But, if you want to do it yourself, have a talk with your EPDM membrane roofing suppliers for their insights.
2. EPDM Membrane Thickness
EPDM roofing membranes come in various standard thicknesses, like 45 mil (1.1 mm), 60 mil (1.5 mm), and 90 mil (2.3 mm). According to EPDM roofing membrane manufacturers, thicker membranes also have a larger shelf life. They can withstand harsh weather better and are ideal for high-traffic areas.
While the thicker membranes are more puncture-resistant, they may not support poorly constructed bases. Therefore, before buying thick EPDM roofing membranes, you must check your roof’s current condition and repair it if needed.
3. Design and Slope of the Roof
Do you know, roofing designs are now evolving, and EPDM supports most of them? Nevertheless, the installation should be done right, and you must inspect the condition periodically.
For instance, flat or low-slope roofs that allow water to pond for extended periods. Is water pooling on roofs normal? Yes, they are. But what happens next? Prolonged water pooling may reduce the life of your EPDM membrane roofing. Eventually, it will also affect the HVAC systems you have in your house.
4. Climate and UV Rays
UV rays interfere with the composition of EPDM polymers and induce aging. Along with this, you cannot ignore the effect of strong winds and severe rains. Constant exposure to various weather elements makes the EPDM waterproofing membrane application faulty.
What is the solution?
Here comes the color of your EPDM roofing membranes into play. Black EPDM absorbs heat, which can help in colder climates but may increase HVAC loads in warmer zones. Thus, in warmer zones of the world, white EPDM can be an option. You can choose a reflective coating, as well.
5. EPDM Membrane Roofing Maintenance
You can choose a better quality of roofing membrane by paying a higher EPDM roofing membrane price. If you are not maintaining it, the results might disappoint you!
Routine inspections, debris removal, and minor repairs can significantly prolong roof life. It is easy and quick. Moreover, you do not need to be a professional to carry out these routine tasks.
What are the signs that tell your EPDM Membrane Roof System Needs Help?
Even the most sincerely maintained EPDM membrane roofs need help at times. Here are some signs you mustn’t ignore:
- Seam lifting or splitting
- Blisters or bubbles under the membrane
- Water ponding for over 48 hours
- UV chalking or cracking
- Roof leaks or interior water stains: Due to ponding water
