I would add insulation to the roof to fill the gap along with
helping noise reduction and heat/cool.
Big difference in the quietness inside.
Different types are available from the StreetRod shops, and the
bubble type (don't use in floor-bubbles may pop) from home
improvement centers.
If need be add supports at flex spots so insulation keeps it from
flexing.
Hope this will help.
Just my Thoughts,
Walt
