We have a sunroom that was probably put in sometime in the 90s as a kit. It has a flat roof (not a normal roof but part of the kit) that is metal sheeting of some kind with styrofoam or something in between as insulation. It kind of comes up under/against the existing roof and connects to the sunroom walls. Anyway the sloping on it is no longer right and we would like the slope fixed and it to be resealed somehow. Can anyone recommend someone that can do this kind of work? Thanks in advance!
