Dear all, please see attached photo
My questions:
1. Does this type of water ponding on a new modified bitumen roof OK? As the water seems to sit there for a while now, and the surface area with water start to turn rusty color (not sure why, maybe it was because of the aluminum coating?). If the water continue to sit there for a while, could that potentially create some bigger problem (this house is in San Francisco, and we have fog all year round - not too much sunshine here).
2. Usually how would a professional roofer handle/address this type of problem?
Thanks!!
