Is 28 gauge normal for a steel panel roof? Which finish lasts longer, painted or silver galvalume? The interior of my house has a cathedral, tongue and groove ceiling. What precautions, consideration or advice do you have regarding a steel panel roof over this? Are there any special considerations when installing a "cricket" or "saddle" between a steel roof and a wood paneled chimney? Are aluminum gutters OK with a steel roof and should gutter revision/repair happen before or after a new steel roof is installed?

28 gauge is not unusual though there are thicker metal roofs as well. I would inquire whether the product meets the base metal and coating requirements of the Metal Construction Association certified roofing program. Generally, a painted product will last longer and have less maintenance than an unpainted one. Steel roofing going into aluminum gutters will likely not cause a problem. It sounds like you have no ventilation in your roof assembly. Building Codes call for a minimum 1" airspace beneath the roof deck. I would suggest working with a well experienced metal roofing contractor and seeing if some ventilation can't be accomplished with your new roof. There are several ways in which it could be done. I would suggest removing the old gutters, installing the roof, and installing the new gutters.

what lengths does metal tin come in?

They can generally be ordered to exact lengths although there is a minimum and a maximun handling length. This leaves us to what you mean by "metal tin". Th majority of metal roofing today is made from Steel and Aluminum. The steel has a rust resistant metalic coating on it such as Zinc known as galvanized or a combination of zinc and aluminum known as Galvalume. For exposed roofing you want to use Galvalume with a coating weight of AZ 55.
