The Impact Of Roofing On Indoor Air Quality

In recent years, we have all become more aware of the impact that indoor air quality can have on our health. With baby boomers retiring and an increasing number of Americans working from home, improving residential air quality has never been more important.

While most homeowners consider factors such as mold and dust exposure, the impact of roofing on indoor air quality still needs to be understood. In this article, we will discuss how roofing impacts air quality and provide useful information that might help you create a healthier home environment.


If your roof leaks, you likely have poor indoor air quality. Roof leaks can lead to the buildup of moisture in your ceiling. Moisture buildup degrades your roof’s structural integrity over time and provides a perfect environment for mold to grow.

Once mold is in your ceiling, it will become airborne and be carried throughout your home. If left unaddressed, you and your family could breathe mold spores and potentially suffer health-related complications. Long-term mold exposure has been known to cause allergies and other respiratory problems.

Roof Maintenance

In addition to looking bad, poorly maintained roofs can cause indoor air problems. Over time, nearly all roofs accumulate dirt, debris, and animal infestations. With regular maintenance and cleanings, this accumulation can be removed, substantially decreasing the risk of roof damage and air quality problems. But if the accumulation continues over time, organic matter can enter your home and decompose, causing odors and other indoor air quality issues.

Roof Installation

Craftsmanship is essential when installing a roof. If your roof is installed without great care, seams and cracks can allow pollutants, moisture, and organic material to enter your home. It is critically important that your roofer use proper technique and materials to avoid negatively impacting your indoor air quality.

When installing a new roof, your roofer should use non-toxic sealants and insulation materials. This should be a standard practice across the industry, but it is not in many cases. Installing environmentally-friendly products is critically important to ensuring your family’s health.

Roofing Materials

Some roofing materials emit harmful substances into the air. For example, low-quality asphalt shingles release volatile organic compounds (VOCs) when exposed to sunlight. If your roof is toxic, there is a good chance that you and your family are breathing in unhealthy chemicals.

We always recommend using non-toxic roofing materials when possible. The cost savings of using cheap materials aren’t worth the risk of damaging your health. We favor materials that have a minimal impact on indoor air quality, such as metal, clay tile, and cedar shakes.
