Cedar shakes have long been a popular choice for roofing material due to their rustic elegance and natural durability. However, like any organic material, cedar shakes are subject to decomposition over time. In this article, we will explore the factors that contribute to the decomposition of cedar shake roofs and how homeowners can maintain and extend the lifespan of their roofs.
Understanding Cedar Shake Roofs
To understand the potential for decomposition, it is important to first grasp the composition of cedar shake roofs. Cedar shakes are made from split logs that are typically cut from Western Red Cedar trees. These logs are then further processed into individual shakes, which are installed on the roof to create a distinctive and visually pleasing pattern.
Cedar shakes are highly regarded for their resilience and resistance to various weather conditions. They possess natural preservatives that make them resistant to rot, decay, and insect damage. However, it is essential to note that no roofing material can be completely immune to deterioration with time.
Factors That Contribute to Decomposition
Despite its innate durability, several factors can contribute to the decomposition of cedar shake roofs. These factors include:
- Exposure to Moisture: Cedar shakes require regular exposure to sunlight to dry adequately after rain or snowfall. When the shakes are constantly damp, they become a breeding ground for mold, mildew, and fungi. Over time, the constant exposure to moisture can break down the organic fibers of the shakes, leading to decomposition.
- Lack of Maintenance: Regular maintenance is crucial to preserving the integrity and lifespan of cedar shake roofs. Ignoring necessary repairs, such as replacing damaged shakes or fixing leaks, can accelerate the decomposition process. Neglecting maintenance allows water to seep into the underlying structure, further contributing to decay.
- Accumulation of Debris: The buildup of leaves, branches, and other debris on cedar shakes can trap moisture and prevent proper drying. This moisture trapped underneath the debris can accelerate the decomposition process. Regularly clearing debris from the roof can help prevent this issue.
Extending the Lifespan of Cedar Shake Roofs
While decomposition is inevitable to some extent, homeowners can take several measures to extend the lifespan of their cedar shake roofs:
- Regular Inspections: Schedule annual inspections with a professional roofing contractor to assess the condition of the cedar shakes. Identifying and addressing minor issues promptly can help prevent more extensive damage.
- Proper Ventilation: Ensure that the attic or roof space underneath the shakes is adequately ventilated. Proper ventilation allows for consistent airflow, which helps in drying out any moisture that may have penetrated the shakes. This reduces the risk of decomposition.
- Prompt Repairs: Address any damage or issues promptly. Replace cracked or damaged shakes, fix leaks, and clear debris regularly to prevent moisture buildup.
- Gentle Cleaning: Periodically clean cedar shake roofs using a gentle solution of water and mild soap. Avoid using high-pressure washing methods, as they can damage the shakes. Gentle cleaning eliminates accumulated dirt and algae, enhancing the lifespan of the shakes.
While cedar shakes exhibit excellent durability, they can decompose over time due to factors such as moisture exposure, lack of maintenance, and debris accumulation. Homeowners can, however, take proactive measures to extend the lifespan of their cedar shake roofs. Regular inspections, proper ventilation, prompt repairs, and gentle cleaning are essential elements of a maintenance routine that ensures the long-term beauty and functionality of cedar shake roofs.
