Mulitple types of mold in the Attic - Stack Effect

There are multiple types of mold in this attic. Moisture in the attic can be caused by lack of ventilation, lack of insulation, improper venting of bathroom and kitchen fans and the most common (in this case) which most people don't think about is stack effect. Stack effect is when the attic of a structure gets to over 120 degrees during a hot summer and cannot vent due to inadequate roof ventilation, it draws up the moisture from a basement or a crawlspace. It will pull all moisture from areas below up into the structure causing damage & mold. Home inspection by John Frejeris
