We are in the middle of having a standing seam roof installed and experienced 3 days of heavy rainfall. The metal is being installed over a layer of mineral board insulation on styrofoam on metal decking. A waterproof membrane is covering the mineral board but this did not stop water from getting in at the ridges and hips that were not complete. The Owner is concerned that we now have water under the metal, in the underlayment and there will be mold and all sorts of other problems because of the water penetration. Are these valid concerns and, if so, how do we deal with correcting the problem?

Unfortunately, you have provide just enough information to get me in trouble, however here are some thoughts. It sounds like a commecial installation and with the insulation on the deck it must be a vaulted type construction. Assuming the roof has adequate slope as it has hips and depending on the type and application of the waterproof membrane, any water should migrate down and out at the eaves provided a proper eaves detail was constructed. Then you are looking at a short term issue providing the standing seam has flutes at the vertical seams, providing ventilation at the eaves, hips and ridge will help absorb the remaining moisture into the air and exhaust it. The worse condition is if it is a very flat residential profile with long rafters and the sheets are laying flat to the styrofoam. The best situation is if it is a commercial 3" seamed roof with fluted flat area and stand off clips. Hope this helps.

You are right, it is a commercial installation as you described with a 6/12 slope. Thanks for your input.
