HI. this past fall, I had a new standing seam metal roof put on an old house that used to have metal shingles. The old decking is just 1/4" boards (I think) that are spaced several inches apart. Unfortuantely, with the new roof, the wind noise is just terrible. IT keeps us up at night-- sounds like there are people in our attic flapping around sheets of metal. I have 2 questions.
1: Is this the normal way to go about putting on a new metal roof? Should the contractor have at least asked us if we wanted to put up new plywood sheathing?
2: Is there anything that I can do at this point to stop the noise? Any insulation products that can be put on the underside of the roof inside the attic to dull the noise?
Any help would be much appreciated !
