Attic Humidity Is A Roof Enemy

Updated: Jun 30, 2023

As summer begins in Harnett County, North Carolina, residents prepare for the inevitable increase in humidity, well-known to this region. Often, the focus is on the discomfort caused by humidity, overlooking the potential damage it can bring to our homes. In particular, attics—commonly overlooked spaces—are highly vulnerable to damage from excessive moisture. Understanding the impact of summer humidity on roofs is key to being prepared to implement preventive solutions through proper roofing and ventilation systems.


The Impact of Attic Humidity


Checking for attic humidity damage

Summer humidity in North Carolina can have a significant impact on attics. Inadequate insulation and ventilation make attics particularly vulnerable to internal damage caused by high humidity. Problems such as mold and mildew growth can lead to structural damage in the form of wood rot which in turn weakens the roofing supports. In North Carolina's summer, the combination of high humidity and extreme heat can lead to visible roofing issues like shingle blistering, water damage, and rot in poorly ventilated areas, which can further increase energy costs.


Prevention Through Proper Roofing Materials and Installation

Preventing attic damage from summer humidity begins with investing in appropriate roofing materials and ensuring their proper installation. High-quality, moisture-resistant roofing materials like metal or asphalt shingles with waterproof coatings can provide added protection against humidity. It's crucial to hire professional roofing contractors for correct installation to ensure your roof is sealed, reducing water penetration and potential attic damage.


The Role of Adequate Ventilation Systems

An effective ventilation system is essential for maintaining a moisture-free attic. The installation of ridge and soffit vents promotes proper air circulation, letting warm, moist air escape and draw in the fresh air. Attic fans can also be employed to expel hot air, decreasing humidity levels and preventing moisture-related problems.


Insulation and Vapor Barriers: Key Components of a Humidity Solution


Ventilation helps deal with attic humidity

Proper insulation combined with vapor barriers can significantly alleviate the effects of summer humidity in your attic. Appropriate insulation creates a thermal barrier, reducing the chances of condensation and moisture buildup. Vapor barriers, such as plastic or foil sheets, keep humidity at bay by preventing moisture from seeping into the attic.
