Challenge: Heavy frost / moisture occurring in attic of 2 yr old two story home.

Atmospheric Temp: -15

Comments:

Sun loading on roof sheathing evident in attic images.

Images show that little airflow is occurring in attic and stagnant air is retaining humidity.


Appears moisture has penetrated insulation and is collecting on ceiling vapor barrier.

Recommend increased ventilation and drying out attic insulation once venting in place.

Home exterior front - sun loading evident on RH side of image /  home

Home exterior rear - everything good


Comparative thermal image of neighbor - similar heat signature


Attic - sun loading, wet insulation


Attic - sun loading, blown in insulation


Attic - sun loading with little evidence of air movement at soffit


Attic - moisture / frost collection throughout under side roof sheathing - more venting required

 Attic - wet insulation

Attic - Heat loss from ceiling evident around attic access


Ceiling - moisture collecting on vapor barrier
