2021 Bullet Roof Type

[WVAMike]

How can I determine the type of roof I have on my 2021 Keystone Bullet? Is it TPO or EPDM? From what I have read each one takes its own type of sealant.
Thank you for your assistance.

Dealer told me that if it is smoth it is EPDM. And TPO and Alfa roof is more like a orange peel texture. I can neither confirm or deny .My 2016 cougar has the rough texture to it.

Keystone used Alpha TPO membrane.
