The Impact of Humidity on Your Roof

Too much humidity in your home can lead to a variety of issues, including discomfort, interior damage, and mold and mildew growth. But did you know that your roof can also be impacted by humidity? State Roofing explains further.

Humidity on Your Roof

Damage Due to Intense Heat

The decking, joists, support beams and rafters of the roof may strain, split and expand when exposed to excessive heat. The shingles on your roof may also be impacted by heat that rises from within your home into the attic, causing the shingles to curl, buckle and develop weak spots.

Damage Due to Excessive Moisture

The threat of interior humidity during the winter can seriously increase the risk of water damage to your roof and attic. Condensation happens as damp indoor air rises. If not addressed promptly, issues like rot and mold may start to appear and endanger the structural integrity of the roof. You’ll soon find yourself in urgent need of a roof repair.

Where Humidity Comes From

Daily chores like washing dishes and clothes, hot baths and cooking cause steam to be released into the air, increasing relative indoor humidity levels. Steam may escape from the basement if your property uses a water-based heating system. Your plumbing system’s leaks cause moisture, which evaporates and enters the indoor air.

Keeping Your Roof Safe From Humidity

It’s important to invest in regular roof maintenance to keep your roof in good shape. Make sure your roof has enough ventilation to lessen the effects of heat and moisture. If problems aren’t fixed quickly, condensation and other signs of water damage can occur. By taking care of your roof now, you can avoid having to pay for expensive repairs in the future or having to deal with a premature replacement.
