When your home develops a roof leak, it’s necessary to fix the problem immediately. Quick action will help prevent structural water damage and mold growth. Here is some information on the correlation between mold and leaks to help you and your family prevent issues.

How Mold Develops

Mold thrives in dark areas with high moisture levels. When a roof leak occurs, the attic humidity increases, creating the perfect environment for mold. Once this happens, the organism reproduces by creating spores that float in the air and form new mold where they land. 

How This Affects Your Health

Mold exposure can cause sneezing, coughing, skin irritations, and runny noses.

Individuals with respiratory issues like mold allergies, asthma, and chronic obstructive pulmonary disease (COPD) are at a heightened risk of experiencing severe symptoms when around mold. Older people and children also have a higher likelihood of experiencing mold exposure symptoms, since they have weaker immune systems.

How to Prevent Mold in the Attic

They’ll assess your shingles, gutters, flashing, and attic to identify damage that could result in leaks, preventing them from occurring. If you already have a leak, resolving the issue as soon as possible will reduce the amount of water that saturates your insulation and wooden structures, helping prevent mold.

You can also install a dehumidifier in the attic to lower the moisture content in the space. To maintain safe levels, set the device at 30% to 50% humidity during the warm weather, and 30% to 40% humidity when you are running your heater. Many homeowners also install ventilation in the attic to encourage condensation to evaporate.
