Is EPDM better than felt?

A common roofing material that is still used on commercial structure is felt, layers of a fiber mat that has a bituminous layer coating applied. A simple roof that is budget priced, which is great, but it does have its drawbacks: 

  • Felt roofing doesn’t have a long lifespan – maximum 15 years versus 50 years for EPDM roofing 
  • Felt roofing is resistant to extreme weather, becomes soft and warped in the sun, then brittle and weak in cold weather. 
  • Repairing felt roofing doesn’t leave a good curb appeal, has a scruffy look, where as EPDM repairs are rare and when they are repaired, it blends in with the roofing.

What is the difference between EPDM and TPO roofing?

There are few differences, and both can suit a building and budget, depends on what you’re looking for in your roofing material: 

  • EPDM is a dark surface, so during the summertime, it may not be the best for buildings in areas where temperatures get hot.  TPO has a light colored surface that reflects the UV rays and heat, keeping the building cooler. 
  • TPO has a higher puncture resistance than EPDM roofing 
  • TPO roofing is welded which makes it an extremely durable system but also a complicated system to install and repair
  • EPDM has been around longer – 60 years versus 10 years – and has a reputation established

Is TPO more expensive than EPDM?

Upon install yes and when it comes to repairs, yes, because it has to be welded where EPDM is simply applied. And EPDM repairs take only flashing tape by the maintenance crew versus having to call a roofing contractor to weld any repairs needed. 

EPDM roofing, felt roofing, TPO roofing all have their advantages and disadvantages.  The building owner and maintenance manager should weigh the differences and choose the one that is right for their structure, the environment, and the budget for installation and budget for future repairs.
