Your roof material is likely EPDM (vs TPO). Use a conditioner / protectant that is formulated for EPDM (non-petroleum based).
That said, contact Dicor to determine if they are the supplier of your roof material (vs Alpha). If they are, share with them, your experience as well as relevant photos. It could be that the material is prematurely failing. In that case, they may wish to participate in some sort of remediation.
