The Impact of Cincinnati's Air Quality on Roofing Materials

As a reliable roofing contractor in Cincinnati, Ohio, we understand that the quality of the air in our city can significantly impact the lifespan of roofing materials. Environmental factors, such as air pollution and high humidity, can cause damage to roofing materials, leading to costly repairs and replacements. In this blog post, we will discuss how Cincinnati's air quality affects roofing materials and what homeowners can do to protect their roofs.

Air Pollution

Cincinnati is situated in an area that is infamous for poor air quality, which can harm roofing materials. The city's close proximity to major highways and industrial areas results in high levels of air pollution from vehicles, factories, and other sources. This pollution can have a considerable impact on roofing materials, particularly those made of asphalt.

Asphalt shingles are the most commonly used roofing materials in Cincinnati, and they are vulnerable to damage from air pollution. The pollutants in the air can react with the asphalt, causing it to break down and deteriorate. This can lead to damage to the shingles, such as cracking and curling, and eventually cause leaks and water damage to the roof.


Cincinnati is also notorious for its high humidity levels, especially during the summer months. Humidity can be a significant factor in the degradation of roofing materials, particularly those made of wood. High humidity can cause wood to expand and contract, leading to warping and splitting. This can weaken the structure of the roof, making it more prone to damage from the elements.

Mold and Mildew

Apart from air pollution and humidity, Cincinnati's climate is conducive to the growth of mold and mildew. These fungi can thrive in warm, damp environments and spread rapidly across a roof. Mold and mildew can cause discoloration, staining, and other damage to roofing materials. They can also pose a health hazard to homeowners, particularly those with allergies or respiratory issues.

Protecting Your Roof

While there is no way to entirely eliminate the impact of Cincinnati's air quality on roofing materials, homeowners can take steps to safeguard their roofs. Regular maintenance and inspections can help identify and address issues before they become major problems. This includes cleaning the roof of debris, such as leaves and branches, that can trap moisture and promote mold growth.

In addition, homeowners can consider using roofing materials that are more resistant to air pollution and humidity. Metal roofing, for instance, is less vulnerable to damage from air pollution and can withstand high humidity levels without warping or splitting. Other materials, such as slate and tile, are also suitable options for homeowners who want a durable and long-lasting roof.


Cincinnati's air quality can have a considerable impact on the lifespan of roofing materials, causing damage and leading to costly repairs and replacements. By taking proactive measures to protect their roofs, such as regular maintenance and using durable materials, homeowners can ensure their roofs last for many years to come.
