Iso foam boards over existing flat roof

Guest User
I have a flat roof on my addition on my house, I would like to attach 4X4 iso foam boards to the existing roof to create a pitch for water to run off.The existing roof is rolled asphalt shingle that has been whitecoated. Do you think I can glue and screw the panels right to the surface?
