When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation.
If your home does not have proper and effective attic insulation, heat can escape from the living space during the cold winter months. Heat is transferred from the living space and also generated from recessed light fixtures, air ducts, furnaces and other appliances and equipment located in the attic. This heat raises the roof temperature above the freezing point, causing the snow and ice on the roof to melt and flow downward.
Possible cause: Insufficient attic ventilation causes heating/cooling system to run excessively
In warm weather, inadequate ventilation will trap hot air in the attic, causing air conditioning systems to work harder, or leaving your home’s interior hotter and less comfortable. Attic Ventilation: In both hot and cold weather, insufficient attic ventilation may cause moisture in the attic to become trapped and condense on the rafters. This condensed moisture can drip down onto the insulation and reduce its effectiveness.
When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation. The air in the attic needs to flow freely from the soffit to the ridge to reduce humidity. Make sure there is a vent in areas such as the kitchen or bathroom. Dryers should vent outside.
