Moisture And Mold: A Serious Roofing Issue

Moisture underneath a roof can create the perfect environment for mold growth, which can cause serious damage to your home and pose health risks to you and your family. Here's how moisture can lead to mold damage and how to deal with this issue.

Causes of moisture

Moisture can accumulate under a roof for a variety of reasons, including roof leaks, poor ventilation, and high humidity levels. When water gets trapped underneath the roof, it can create a damp environment where mold can thrive.

Signs of mold damage

If you notice a musty smell, discoloration, or stains on your ceiling or walls or an increase in allergy or respiratory symptoms, it's possible that you have mold damage caused by moisture under your roof.

Dealing with the issue

If you suspect that you have mold damage caused by moisture under your roof, it's important to take action to address the problem. This may involve repairing any leaks or ventilation issues, as well as removing any mold that has already formed.

Mold Remediation

Mold remediation involves removing mold from your home and treating the affected areas to prevent future growth. This process may include using specialized equipment and chemicals to remove the mold, as well as repairing any structural damage caused by mold growth.


To prevent moisture from accumulating under your roof and causing mold damage, it's important to ensure that your roof is properly maintained and inspected regularly. 

  • The amount of ventilation required depends on the size of your roof, the type of roof, and the climate you live in.
  • Intake vents allow cool, fresh air to enter the attic space. These vents are typically located at the soffits or eaves of the roof. It is important to make sure that the vents are unobstructed and properly installed to prevent leaks.
  • Exhaust vents allow hot, moist air to escape from the attic space. These vents are typically located near the peak of the roof and can be in the form of ridge vents, gable vents, or turbine vents.
  • It is important to make sure that the intake and exhaust vents are properly balanced to ensure adequate airflow. 
  • The type and amount of ventilation needed may vary depending on the climate you live in.

By addressing the issue quickly and taking steps to prevent future moisture buildup, you can protect your home and your family from the potentially harmful effects of mold growth. Speak to a professional roofer and learn more about managing moisture issues under your roof.
