We are planning to install an exposed fastener steel roof over an asphalt shingle roof. The building is a small chapel that is used only once or twice a month and then is not heated or cooled the remainder of the time. Will this create any unique problems as it will be heated for several hours to a day and then shut off. It is not used in the summer months. We are in WI so snow, ice damning issues etc are real and summer can be hot/humid and this building is not used or cooled in the summer. It is a small building and it does have a pitched roof. Also what is "installed with solid sheathing" mean? I read this in comments about noise reduction. I am trying to assure that the steel roof will not be really noisy in rain while the chapel is being used. Also I see barriers are applied in some videos and not in others. I see wood slats used to nails the steel too. Are both of these necessary and if so why or why not? I am not a roofing person but just trying to make a smart decision for a small project for our chapel.

Has the roof ice dammed before? If you were to incorporate some purlins and some vent space above the old roof, that should keep the ice damming to a minimum.
