Inconsistent indoor comfort, damage to interiors, and mold and mildew growth are some of the ways indoor humidity affects your home. But did you know that even the roof is not exempt from its effects? Genesis Roofing explains how.

How Humidity Can Cause Roof Damage
Humidity, if not controlled, can be damaging to your roof. One of the most common problems associated with it is the expansion and contraction of roofing materials due to moisture. Shingles, for instance, can warp or curl when they absorb water and dry out. Meanwhile, metal roofs may also be subject to expansion and contraction, potentially loosening fasteners and causing leaks.
Another issue caused by humidity is mold and mildew growth on your roof. This poses health risks to your family and can lead to structural damage if left untreated. Mold and mildew are attracted to damp, poorly ventilated areas, like your attic.
Excessive humidity can cause the rot and decay of wood components in your roofing structure and the degradation of insulation materials. This can result in reduced energy efficiency and costly repairs if not addressed promptly.
Signs Your Roof May Be Suffering from Humidity Damage
Keep an eye out for these telltale signs that humidity may be causing damage to your roof:
- Curling or buckling shingles
- Discoloration or stains on ceilings and walls
- Soft or sagging areas on the roof
- Visible mold or mildew growth
Preventing Humidity-Related Roof Damage
Fortunately, there are several steps you can take to prevent humidity-related damage to your roof. One of the most crucial measures is ensuring proper ventilation. Installing the right amount of intake and exhaust vents will help you regulate temperature and moisture levels in your attic, minimizing the buildup of excess heat and moisture.
Regular maintenance and inspections by a reputable roofer are just as important in keeping the roof from getting damaged because of humidity. Keeping an eye out for potential issues and addressing them promptly is key to avoiding costly repairs or even a premature roof replacement.
