The Damaging Effects of High Humidity on Your Roof

Your roof might look well and dry after a storm, but it might have hidden damage, especially if you live somewhere with high humidity. River or seaside properties and areas with frequent rain often have extremely humid environments that they can corrode metal roofs and other components. If you live in these areas, even asphalt and clay tile roofs could endure massive damages. Read on to learn more about them.

Increased Moisture

The granules on asphalt shingle roofs protect them from moisture infiltration and retention. Still, if they're always exposed to moisture evaporated in the air, these granules can break down, causing the material to absorb them and lead to blisters later.

Mold Growth

Mold and mildew thrive in wet and dry environments. In an area with high humidity, your roof might have patches of slippery mold and mildew. These eat away at the protective granules, damaging the material and shortening its lifespan. The attic and insides of your roof aren't spared – high humidity in the attic will cause expensive structural damage and affect the property's overall durability.

Expansion and Contraction

In a humid environment heavy with moisture, roof materials will expand with cracks, gaps, and loose or missing shingles. If you leave them unrepaired or do not replace them, leaks across your roof will spread and soak the wooden structures of your attic, ceiling, and eventually the rooms of the property.

Structural Issues

High humidity levels in your attic can weaken your roof structures. Excessive humidity encourages mold growth and allows moisture to infiltrate your roofing components, causing the wood to rot if left unattended. Moreover, moisture and hot air can shorten the lifespan of your asphalt shingles.

You can prevent high humidity in your attic by ensuring the space has excellent ventilation. Proper ventilation allows warm air to escape, preventing heat and moisture buildup, and extending your roof’s lifespan.

Outdoor Moisture

High humidity can be a result of your indoor or outdoor environment. During summer, your outdoor area may seem dry, but there could be plenty of moisture in the air. This can cause damage to your roof structure and other components. 

Fortunately, with regular residential roofing inspections, you can detect roofing issues early and carry out repairs before extensive damage occurs. 

How to Manage Indoor Humidity

A house with normal indoor humidity levels promotes a longer roof lifespan. If you notice excess humidity in your attic, try using a fan to cool and keep the space dry. You might also need to upgrade your attic insulation. (Continued)
