EPDM and GRP are both popular flat roofing systems. The right option depends on the roof shape, details, installer skill and how the roof will be used.
EPDM rubber roofing
EPDM is flexible and works well on many simple flat roofs. It can be a good option where movement is expected, but details around edges, outlets and penetrations still need careful workmanship.
GRP fibreglass roofing
GRP creates a hard, seamless surface and can look very neat when installed correctly. It is especially dependent on preparation, weather conditions and correct detailing.
How to choose
Ask the roofer why they recommend one system over another for your exact roof. The answer should mention deck condition, falls, edges, outlets, rooflights and maintenance.
