I am struggling with musty smell coming down from attic in hot summer months. The house was built in 2010 and it has soffit and ridge vent. There is no other vent in attic. I have no trees around the house, so in summer, it gets full sun for the whole day and attic gets extremely hot. I am struggling to find a solution to the problem. I was suggest to put a gable vent also. But I am not sure what is the right solution.
Any help provided will be greatly appreciated.
