How Humidity Affects Roofing Systems

Your roof protects you and your family from the scorching sun and relentless rain. In doing so, however, it is subjected to weathering, in which the materials and components that make up this part of your home wear down over time. While we often tend to pay attention to the effect of rain and heat on the roof, there’s one threat that’s often overlooked, and it lies in the outdoor air.

How Humidity Affects Roofing Systems

In this blog post, Window World of Boston, one of the top roofing and siding replacement contractors in the area, discusses the impact of humidity on roofs.

The Stealthy Impact of Humidity

Humidity is the amount of moisture present in the air. High levels of it can affect your roof in ways that often go unnoticed until it’s too late. That’s because it creates the perfect environment for mold and mildew to thrive, resulting in insulation problems, structural damage and health hazards. Combined with heat, humidity hastens the aging and deterioration of different roofing components, weakening the system’s integrity and reducing its life span.

The Silent Threat of Mold and Mildew

One of the prevalent effects of humidity on roofing systems is the presence of mold and mildew. These organisms proliferate under damp conditions, finding their way to the deep corners of the structure. Eventually, the wooden components of the roof, particularly the trusses and rafters, start to rot, compromising its integrity while also posing health risks to every member of the household.

The Expedited Degradation of Roofing Materials

Humidity, when combined with rising temperatures, can do a number on your roofing materials. If you have an asphalt shingle roof, expect it to absorb moisture present in the outdoor air. This, however, results in the material warping, cracking, or losing their protective granules. High humidity levels can cause a metal roof to develop rust, not only making it look unsightly but also jeopardizing its strength and durability. Unless you invest in immediate roofing services, the life span of your roof may become drastically reduced because of humidity.

Decreasing the Chances of Humidity Damage on Roofs

It’s impossible to eliminate humidity outright, but there are steps you can take to protect your roof from it and its consequences. Make sure it has adequate ventilation, where a continuous exchange of moist attic air with drier outdoor air occurs. With the right amount of vents, you can rest easy knowing this part of your home won’t accumulate excess heat and moisture. Investing in professional maintenance is also vital to keeping the roof intact and in great condition.
