Multi rib metal roof on double wide...static vents

Hello all,
Due to some storms and resulting hail damage I must replace the roof on my double wide. It is a 2007 home with a "traditional" double wide roof aka.... 3/12 pitch with a few static vents on each side of the home but not cathedrial flat 8' ceiling inside. The home is currently shingles and I would like to replace the shingles with a multi rib exposed fastener metal roof (its simpliest and cheapiest honestly). There is only one layer of shingles on the home however I do plan to remove these to save the weight (it is a double wide after all so why not). I will use new 30# felt as it is also cheapier than the synthetic underlayments as well as butyl tape or caulk due to the low slope of the roof. I have selected a material that is appropriate for my roof. I have not yet removed the ridge cap on the home now but am sure that more than likely there will be a marriage wall there preventing me from cutting the decking and installing a vented ridge cap. I would like to remove the current 1' x 1' static vents on both sides of the home and cut and install a vented ridge cap (I do have soffit vents installed) however I am almost certain I will not be able to do this and if I can I am not sure it will adequately vent my roof. do I install static vents with the metal roof? Can I cut a hole in the metal as with a plumbing vent and purchase a plastic or metal 1' x 1' static vent to place over top of the hole and the metal with butyl caulk? Or do I have to cut the metal and install the top of the vent under the top piece of metal and the bottom of the vent over the botton piece of metal similar to a shingle installation? I not able to use these square 1' x 1' static vents and should install something else? I think I have a lot figured out but cannot find information on what to do with these vents anywhere. Please help.
