Humidity has significant effects on buildings, particularly roofs. Different roofing materials react differently to excessive moisture, often leading to expensive repairs or replacement. In this blog post, Renovation Team explores how humidity interacts with various roofing materials and how it can affect the integrity and longevity of roofs.
Expansion and Contraction
Humidity affects most materials, including roofing materials and vinyl siding installation. Excessive moisture can cause roofing materials to expand and contract. Metal panels, for instance, are vulnerable to rust and corrosion. Wood materials, such as cedar shake, can deteriorate. Asphalt shingles are also prone to rot and other forms of damage if exposed to moisture for too long. If not addressed, these issues can degrade the roof’s integrity. Ultimately, this leaves your roofing vulnerable to leaks and other potential problems.
Roof Coating Damage and Corrosion
Most roof coatings protect the roof from ultraviolet lights and water damage. However, they can weaken when exposed to excessively moist environments. These coatings become soft and brittle, losing their ability to protect the roof from the elements. In addition, this weakens the roof’s ability to reflect solar radiation and prevents its cooling capabilities. As a result, your roof’s energy efficiency may greatly suffer.
Another problem arising from excess moisture in the atmosphere is condensation. This occurs when warm, humid air comes in contact with the colder surface of the roof and materials such as pipe insulation and ducts. This creates a perfect environment for mold and fungal growth, even in new roofing systems. This can cause significant damage to the roof and its underlying structures.
The best way to protect your roof from the damaging effects of humidity is to take preventive measures. Regularly inspecting the roof for signs of damage is the most crucial step. If there’s evidence of degradation, get in touch with a professional roofing contractor as soon as possible. Consider having your roof equipped with a vapor barrier, which is a thin sheet that prevents moisture from penetrating the roof and onto the underlying materials.
Humidity can significantly impact your roof’s lifespan and effectiveness. However, it can be efficiently addressed and prevented with regular inspections carried out by professional roofers.
