    Default mold on wooden open beam ceiling

    have a post and beam patio room with glass windows on southwest side.
    mold is salt and peppered all over the ceiling. no water leaks during raining was noted.Roof is 6 years old, torch-on type with 1/2" per ft. drainage. most of the mold is on the knots in the wood. No insulation on the roof.
    roofer said its a condensation problem, roof inspector say bad workmanship. found a couple of exposed nail heads at skylite flashing. now what???

    Are you describing windows on one side and OPEN on the other side(s), or
    windows on one side and CLOSED in on other sides?

    If closed in, is it heated and cooled, ventilated?

    Pictures would help....

    So was this a porch that was closed in to make a room?

    How old is the home? Does it have central air/heat?

    Wash off the mold. Insulate the ceiling.
    A few exposed nails can't be blamed for a design fault.

    You could try running a ceiling fan to circulate the air.

    When was the mold first noticed? What changed in either the use or construction of the house just before that? Include in your thinking increased occupants, changes in cooking habits, shower usage, heating/air conditioning usage. How about changes in the building, like insulation, windows, even weather stripping?The list is endless, but you get the idea.

    If the room is open to the rest of the home, and is staying warm...I would look into a ceiling fan like stated above. Circulating the air in the room will help I would think...especially if there isn't any noticeable leaks or moisture around. If that dosen't seem like it is the answer, then maybe you should look into possibly having the roof repaired if it is coming from there. Has anyone ever browsed the angie's list roofing contractorsbefore?
