Leak or Condensation? How to Identify Mysterious Moisture| Ep. 58

Metal Roof
How to determine if moisture is from a leak or condensation.

On this Week’s Podcast: Mysterious Moisture

When there is moisture where it shouldn’t be in a home, mold and mildew quickly follow.

Homeowner Wade says he’s confused about why moisture is showing up on his new roof. He says he always notices the water during warm weather.

Wade had the roof addition built with an ice and water shield added underneath and he still notices moisture around the soffit area.

After removing a metal soffit, he noticed about an inch of frozen ice. 

We tell him a common area for leaks is often at the point where an addition joins the existing part of a home. 

However, this may not be a leak at all. It’s most likely a sweating issue — metal roofs tend to sweat because of a lack of airflow. 

Wade was right to install an ice and water shield with the roof. He also can eliminate the condensation by adding extra ventilation and possibly some additional insulation.

Ridge vents or gable vents will help eliminate the condensation issue. Adding soffit vents introduces cool, fresh air to your attic as hot air escapes from the top of the attic through ridge vents, attic fans or gable vents. This project is easy to handle and will help bring down your home’s cooling costs. 

Additionally, Wade says he has a shallow pitched roof that could worsen the problem with moisture. 
Our advice is to add extra ventilation to his brand new metal roof.
