    Throw in a couple collar or rafter ties for good measure. Plus make sure your gable ends are structurally connected to the top plate supporting the rafters.

    Not to take away from some of the good advise listed above, but if you want a cheap and fast temporary solution, you might try what I did. I too had a condensation problem in an area of my sugar shack. I took plant bed canvas, which is just real light/thin material, a bed sheet would work, and attached it to the bottom edge of my rafters. I don’t know if it partially insulates the roof metal, or allows the air to travel up the rafters keeping the moisture out. Anyway it doesn’t rain in there anymore.

    AFretired, That is a great, cheap and fast idea. Are you talking about the black fabric you lay down to prevent weeds?

    No, it’s white and real thin, but anything like it would probably work. Cheap flat bed sheets would probably work. I just stretched it tight and stapled it to the rafters.

    If you do add rafters, there is no reason to use 2x8's for a 12' wide structure. Does the top have a peak style or an arched type? If a peak, add a bottom plate then 2x4 studs max 24" spacing, thus 55" will need 2 between each, then a top plate. Add at least 1 or better 2 cross ties to prevent spreading. Then 2x4 rafters, or if concerned even 2x6 rafters. Then put plywood or OSB on it, then ice/water shield and finally steel roofing. As long as the rafters are 7' or less and you have a 3/12 or steeper pitch 2x4's are sufficient on a 3/12 or steeper roof (3" rise per foot horizontal). If you try the fabric idea I'd suggest just 1 season, then do it right.

    If the OP is going to be adding rafters, top and bottom plates, studs and then sheeting...may as well just build a new structure and be done with it.
    I don't see how he can get any pitch at all unless the new "roof" is built over the top of the arch roof on the carport.
    Adding to that carport is a bad idea...hanging up a sheet to absorb the condensation is harmless and will solve the immediate problem.

    The thing about hoods and vent pipes, if designed correctly and installed correctly they should be able to remove 95% of the steam from the boiling room. We do have hoods and stacks and generally have only one or two drops of condensate per year off of a nail coming through the roof! Approximately 8000 gallons of water go out the stacks per year. or about 130 gallons per hour when boiling. I did bot want that in the room with me and friends, during boiling.
