Did you know that just having moisture within your roof system can further damage the roofing system? Yes, unfortunately it can. Further damage to the building’s most key waterproofing element, the roof, can occur as a result of moisture.
As water heats within the wet insulation it begins to turn to water vapor. The vaporized water expands creating pressure within the roof system. If the system is open to the interior of the building, the vapor will push into the building envelope and condensate showing up as a roof leak. If the water vapor cannot escape, it will cause blisters in the roof system. As the pressure increases it will find the path of least resistance and place pressure on the system causing openings to occur. Once water vapor can get out, water can enter the system and you have a new roof leak.
