However, long-term exposure to the harsh elements can lead to wear and tear. One of the most common roofing problems involves the presence of humidity inside and outside the home. Roof Damage Caused by Moisture Constant exposure to the sun can cause your attic to trap heat. Add moisture to the mix, and this can result in the growth of mold and mildew. Over time, the wood components of the roofing structure like the joists and rafters may deteriorate. This needs to be addressed before it becomes a health and safety hazard. Roof Damage Caused by Excessive Heat The same wooden components that hold your roof in place can also become damaged because of too much heat. This can lead to the material swelling and contracting every time temperatures fluctuate, creating cracks and openings. Humidity becomes apparent with the presence of water inside the heated attic. Shingles may also buckle, curl or blister because of this, necessitating an immediate roof repair. Dealing With Excess Humidity Roof ventilation helps reduce humidity levels. The right amount of intake and exhaust vents promote air circulation, allowing heat and moisture to escape the attic. According to federal housing standards, a home must have at least 1 square foot of attic ventilation – split between intake and exhaust vents – per 300 square feet of attic floor space. With this, you no longer have to worry about humidity issues that can affect your roof and your home’s comfort needs.
