Understanding how humidity influences your roof is essential to ensure its longevity and effective maintenance. Below, renowned local roofer Christian Brothers Roofing outlines five ways in which humidity can impact roofing systems:
Moisture absorption can be a concern in regions with elevated humidity levels, particularly affecting roofing materials like asphalt shingles and wood shakes. Low-quality varieties of these materials are prone to the effects of moisture absorption, which can result in swelling, warping, or rotting. This compromises the roof’s structural integrity and poses a significant threat to its overall functionality.
High humidity levels create an ideal environment for mold and mildew growth on your roof. These organisms not only affect the appearance of your roof but can also degrade its components, compromising their integrity. Regular cleaning, maintenance and timely roof repair can help prevent mold and mildew buildup.
Humidity can exacerbate the effects of wear and tear on your roof’s flashings and seals, making these components less effective in preventing water intrusion. This, in turn, can cause rot to develop on the wooden components, including the rafters and sheathing. It can also create ideal conditions for mold and mildew growth, posing health risks and requiring costly remediation.
Fluctuations in humidity levels can lead to thermal expansion and contraction of roofing materials. The constant expansion and contraction can cause roofing materials to weaken and degrade more quickly. This can lead to cracks, splitting and a possible reduced lifespan for your roof.
High humidity levels can make your attic space hotter, which, in turn, can increase the workload on your air conditioning system. Professional roofers recommend proper ventilation and insulation to mitigate the effects of humidity and maintain a comfortable indoor environment.
High humidity can accelerate the deterioration of roofing materials, causing issues such as sagging, interior leaks, and extensive mold growth. These signs indicate that your roof may no longer provide adequate protection for your home, necessitating an immediate replacement.
