Our recently installed mechanically fastened EPDM roof seems to balloon up
in winds. We live in a high wind area and 7 years ago our torch down
modified bitchumin roof blew off. In addition, the membrane seems to have
shrunk a bit and is pulling away from where it meets a vertical wall at
the flashing. I think the wind is getting in from the wood fascia board
which is installed under a metal edge. Does anyone know if this is normal?
thanks

If the EPDM was properly installed, according to the manufacturers specs,
some billowing shouldn't be of concern. "Ballooning up" sounds excessive,
but as I can't see it from here, I can't tell you with any certainty. If
the membrane is indeed pulling away from the flashing, that is of concern
and should be looked after.
