How Humidity Affects Roofing Systems

Your roof provides a protective barrier against the heat and bright glare of the sunlight. Over time, constant exposure to these harsh elements will increase the temperature of your roof, leading to a hotter interior environment. If you add in high levels of moisture, it can significantly compromise the efficiency and lifespan of your roofing system.

Heat Damage

Extreme heat can cause wood components, such as rafters, support beams and decking, to expand, stretch and crack. This allows water to seep into your roofing system, potentially setting off an array of mold and mildew problems. The combination of heat from the sun and hot air trapped in the attic can cause shingles to curl up and shrink as well as further increase the temperatures in your living spaces.

Humidity Damage

Too much moisture can damage your roof, including all the wood materials used to build the structure of your system. Moisture can get trapped in your attic or crawlspace. It can also lead to condensation, prompting mold to form on attic floor joists, roof joists and roof rafters. In addition, moisture can initiate the rotting of wood and weaken plywood sheathing.

How to Prevent Damage Caused By Heat and Humidity

Fortunately, there are clear and simple ways to keep your roofing system in good condition. Here are some tips:

Add ventilation. Proper ventilation can effectively minimize the harmful effects of heat and humidity on your roof. If there is poor airflow in your attic, mold can begin to grow and spread on interior surfaces. Make sure to consult a roofing contractor who is familiar with the local climate and can give smart recommendations that will benefit you long term.
Do timely repairs. It is not a smart move to neglect roof repairs to save money. Issues that remain unaddressed for a long time will result in bigger, more expensive repairs.
