4 Most Common Reasons Why Mold Can Get Through the Roof

March 31, 2022

Roofs can also deteriorate despite being the first line of defense in a home. Over time, they may experience wear and tear due to various factors such as the home’s environment. As a result, a deteriorating roof may be a gateway to other issues like mold infestation.

Mold infestation may not seem as much of a problem at first. However, it may trigger several health risks to the humans living in the house. Its most common symptoms are allergies, asthma, and recurring colds. But as time passes by, the infestation may lead to severe health problems such as bleeding lungs, cancer, and central nervous system problems.

But what are the most common causes why molds get through the roof? Here are some examples.

1. Roof Leaks

Leaking roofs are one of the most common causes of mold infestation because water may seep through the roof and enter the ductwork, leading to other parts of the home. It may be easy to hide since the water may not even get out of the ducts. But if it’s left unchecked, the water may eventually find its way to the bedroom ceiling and then to the floors below.

2. Damaged Roofs

Large holes in the roof can also be the source of mold infestation. Leaving such holes unaddressed can potentially cause water to seep in and reach the bedrooms and other parts of the home.

3. Changing Temperatures

Rapid temperature changes can also be a cause of mold infestation. For one, it’s common for a house to have cold air seeping in from the roof when it is cold outside. However, the cold air can quickly evaporate, humid, and water-filled the area. It may cause mold infestation to return to the parts of the house that need to be renovated.

4. Severe Rusting

It’s common to experience rusting in metal roofs, especially when exposed to water. The widespread use of metal roofs doesn’t only depend on their cost and aesthetic. It also depends on their overall durability and the roof’s longevity.

Maintaining the roof during the span of its 10 to 15-year lifecycle is essential. However, rusting is a common thing and can’t be avoided. But usually, rust does not damage the metal coating, and thorough cleaning is all it takes to prevent damage.
