How Does Excess Moisture Damage a Roof?

Moisture infiltration is a type of roofing issue that often starts small. Over time, if left unattended or undetected, it can cause serious damage to the entire roof structure. To prevent costly repairs in the future, the first thing you can do is to be aware of how moisture can damage your roof. 

In this article, Triangle Home Exteriors lists some roofing issues that result from unnoticed moisture problems. 

Weathering of Roofing Materials

Once moisture penetrates your roofing system and your property’s interior, it can damage various materials that make up your home. For example, when water is absorbed in granular materials like drywall, it seeps through the spaces between the particles. This process can cause the material to deteriorate. Another example is ceiling drywall sagging, which happens due to saturation. 

In cellulose-based products, decay can occur when the moisture levels on the materials reach 20%. If your house is mostly composed of wood structures, rot can be your biggest enemy, especially if it continues unnoticed for a long time.

Metal Roof Corrosion

When a metal roof is frequently exposed to rain and moisture, rust and corrosion occur. The metal fasteners and connectors that support your roof framing are made of metal, making them susceptible to rust damage. If left unattended, the damage can spread throughout your roofing system and compromise your home’s structural integrity.

Roof Leaks

Usually, signs of leakage are not always visible because roof leaks occur in the hidden parts of your home, like the attic or wall interior. This problem can increase the level of humidity in your home, making the temperature in your living spaces uncomfortable. As a result, your cooling system will be forced to run more often, which can result in soaring electricity bills.
