How Heavy Rains and Snow Melt can Cause Attic Mold

Published on December 23, 2024

As the climate shifts and warm weather sticks around longer, we’ll be experiencing more rain and snow melt than white winter days in the future. For MoldTech, this means we’ll be fielding more calls for attic mold removal due to this increase in moisture and temperature changes. The attic is one of the first areas to be affected by mold growth from weather. Mold testing in Mississauga can help detect emergent infestations and get you on track for safe and effective mold remediation before problems start to emerge. 

Why Heavy Rains and Snow Melt Lead to Attic Mold

attic mold removalRain and snow’s primary point of contact with your home is the roof, making it critical to keep it in good repair and to monitor it regularly for changes. Small things, such as letting a tree overhang a section of roof, may, over time, cause damage or moisture build-up that can affect the attic and cause changes that lead to mould. The three most common reasons that attics get mold are: 

  • Water intrusion: Leaks from old shingles or roof damage are the classic method in which unwanted water gets into the attic. Shingles can age and become loose, damaged, or worn through; the average roof has a lifespan of 25 years. Weather, trees, ice, poor installation and other natural or human interventions can also cause damage or changes that lead to moisture in the attic. 
  • Poor ventilation: While it may seem counterintuitive, the attic needs airflow to move moisture out and away. It’s when moisture gets trapped that mold growth is triggered. Ensuring soffits are clear and that there are enough vents (and that they work!) is the first step to increasing the attic’s natural ventilation
  • Condensation issues: Unlike the rest of the house, the attic shouldn’t be very warm or cool — a balanced temperature that isn’t too dissimilar from the outdoors is what the attic needs. When this balance is off, condensation may form, introducing dangerous moisture to the attic. 

The Dangers of Attic Mold

When you don’t use the attic for living or sleeping, it may feel like you can ignore or put off attic mold removal. However removed from your living spaces it is, attic mold can still pose a health and safety risk for you and your family. Some of the most common dangers the MoldTech team has come across include the following:

  • Structural damage that has weakened beams, joists, sheathing and other structural components. 
  • Damage to insulation that causes decreased performance and degradation. 
  • Health issues like respiratory problems and allergies from mold spores. 
  • Escalating remediation costs as damage sets in and spreads.

The danger and damage that comes from ignoring attic mold isn’t worth it — professional mold removal is safe, effective, and essential. At MoldTech, we can help you in several ways.
