How is your roof mechanically fastened?? Rubber roofs get glued down,
not stretched and fastened. More information and maybe a photo if you

You have a real oddball there, Mike. Typically flat roofs are done in
bitumen (torch-down), EPDM (rubber), or tar & gravel. Rubber roofs
typically have a service life of around 40 years, glued down, in all
sorts of weather. Temperatures should not be an issue, but uplift can
be, depending on the size of the roof.
