There are many different reasons why water damage can occur in an attic. Improper insulation can contribute to water damage from condensation. Attic insulation, when installed correctly, keeps moisture from developing and warm air from escaping through your roof. If your attic has water issues due to condensation, this is caused by warm air striking the cold exterior surfaces that are not protected by insulation, resulting in frost or water damage. Once moisture is present in your attic, you are at risk of mould or mildew, as well as further attic damage, if left unaddressed. Attics with enough insulation maintain an adequate interior temperature, preventing condensation and moisture buildup.
