DBI has had extensive experience with investigating attic ventilation performance problems that cause high attic humidity conditions leading to mold growth on framing and the underside of the roof sheathing.  DBI can investigate both design and installation and perform code mandated attic ventilation analyses to determine whether the installed attic ventilation system has met code requirements.  Proper attic ventilation coupled with adequate attic thermal insulation will create a cool roof and reduce the propensity for ice dams and their damaging effects.
