How to Tell If Your Roof Has a Leak or Condensation

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

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

Wade, a homeowner we spoke to, says he’s confused as to why moisture is showing up on his new roof. He told us he always notices the water when the weather warms up.

Wade just had a brand new roof addition built with an ice and water shield added underneath and he’s still noticing moisture around the soffit area.

After removing a metal soffit, he noticed about an inch of frozen ice, and now, he wonders what to do about it.

We tell him a suspect 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 more likely a sweating issue. Wade is on the right track by installing an ice and water shield with the roof. The reason why metal roofs tend to sweat is because of a lack of airflow.

Wade 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 the cooling costs for your home.

Additionally, Wade told us he has a very shallow pitched roof that could worsen the problem. It’s best he takes the initiative to add extra ventilation to his brand new metal roof.
