How Does Humidity Affect Your Roofing System?

Many homeowners aren’t aware that their home’s humidity level can affect the condition of their roof. Excessive heat and moisture can shorten the lifespan of your roof. Also, when your interior is too humid, your HVAC system will need to work harder to make your space comfortable, resulting in higher energy costs. Read on to learn more about how humidity affects roofing systems.

What Humidity Does to Your Roof

The wooden components of your roof’s structure will start to expand as the temperature increases.  Wood rafters, joists, support beams can stretch, break, and crack, letting water penetrate your interior. Over time, this can lead to mold and mildew growth. With the heat from the sun and warm attic temperatures, shingle nails can loosen and shingles will curl and shrink.

Moisture can get trapped in your attic and create condensation, which can later contribute to mold growth on attic floor joists as well as roof rafters and joists. Another problem that comes with moisture accumulation is wood rot.

What Can You Do to Protect Your Roof?

Contact your roofer as soon as you notice or think that something is wrong with your roof. Regular maintenance will also help in keeping your roof in good shape.

You can avoid damage from excessive heat and humidity by properly venting your roof. Sufficient ventilation and also using a dehumidifier can minimize condensation in your attic that often leads to mold formation. Your contractor will need to consider your climate and other factors before they can recommend the ideal ventilation system for your home.
