Keep on reading to find out how humidity affects your home’s roofing system.
Excess Humidity Can Encourage Mold Growth
Too much humidity in your attic can reduce the longevity of your roof, which is just one reason you should minimize indoor air moisture in your home. The moisture in the air rises into the attic and your roof. Save on costly home and roof repair by preventing excessive humidity indoors.
Heat and Moisture Damage
When wood roof rafters, joists and decking faces extreme heat, they can expand, stretch, break and crack. If these things occur, water will seep into the wooden components of the roof, resulting in water damage. The sun’s heat and the heat rising into the attic can cause the roofing nails to pop, shingles to curl, and weak spots can develop.
How to Avoid Humidity-Related Roof Problems
One of the best ways to reduce heat and humidity in your roof is by improving the ventilation. Proper air circulation and roof ventilation can help prevent mold from growing and water damage from occurring. An experienced roofer will consider the design of your home, your location and climate, as well as other factors to recommend the best type of ventilation for you.
Keep in mind that delaying repairs will only make roof humidity problems worse. Ignoring or delaying repairs can accelerate the deterioration of your roof and even lead to early roof replacement. Another way to reduce humidity in your attic or crawl space is to use dehumidifiers.
