HELLO, WE HAD A CONTRACTOR BUILD US A 14 BY 45FT ADDITION OFF FROM OUR TRAILOR. THE LAST STEP FOR HIM WAS THE ROOF. NOW WE HAVE A SHELL WITH ROOF. STEPPING INSIDE THIS SHELL ON A RARE WARM DAY IN JANUARY YOU ARE ABLE TO SEE LINES OF WETNESS ON THE CONCRETE FLOOR. THIS ADDITION HAS A COMPLETE FOUNDATION, WITH THE ROOF OVERLAPPING THAT OF THE TRAILOR IN WHICH THERE ARE SHINGLES. NOW IN THE TRAILOR PART WE ARE NOTICING DAMP SPOTS ON THE CEILING, AND OF COURSE THE LINES OF WET IN THE ADDITION. OUR CONTRACTOR PLACED THE ROOFING OVER THE PERLINGS WITH NO BARRIER. IS THIS SMART? IT REALLY DON'T SEEM AS THOUGH IT IS. WE HAVE TALKED TO MANY PEOPLE AND EVERYONE HAS EITHER A STRONG ABSOLUTELY NOT OR WE HAVE ACTUALLY HAD SOME SAY IT SHOULD BE OK. THE ADDITION WILL BE A LIVING ROOM AND BEDROOM, WITH A WOOD PELET STOVE, AND HARD WOOD FLOORS WHEN COMPLETE IF EVER. OUR CONTRACTOR SAYS THAT ONCE THE INSULATION IS IN THERE WILL NO PROBLEM! I WANT IT STRAIGHT FROM THE EXPERTS WHAT SHOULD WE DO? THANK YOU IN ADVANCE FOR ALL YOUR HELP FRUSTRATED

You need a combination of vapor barrier behind your ceilings, good insulation, and positive attic ventilation (with intake and exhaust) between the insulatin and the roofing. Contact the manufacturer of your roofing for more details as well.
