I agree with Ryan, contact local department of labor. They'll point you in the right direction.
Proper ventilation is extremely important for a long lasting roof. If you roof is sweating and creating condenstaion it can deteriorate your entire roofing system from the decking and supports to the underlayment and shingles.
