EPDM roofing
This is an elastic, synthetic rubber roofing membrane and is commonly used with domestic projects. An EDPM roof kit requires complex detailing to ensure you avoid water ingress into the membrane however an EPDM roof kit can be made up off site with penetrations pre installed.
TPO
TPO is seen as a more environmentally friendly option and is heavily used in civil engineering such as for tunnel waterproofing and pond linings. In the past it was sensitive to UV light but this issue has been solved increasing its life expectancy. The issue with TPO is it cannot be welded dirty and can be difficult to keep clean on site.
TPE
This product was developed to improve some of the characteristics of TPO. It doesn't have any of the dirty weld issues and is very simple to install. Whereas PVC or TPO need to be patched small punctures in TPE can be resealed using the application of heat.
