Common Problems with Sheathing and How to Address Them

by | Jul 11, 2023 | Blog | 0 comments

The sheathing is crucial in construction, providing structural support, protection, and insulation for buildings. However, like any other structure component, sheathing is prone to various issues that can compromise its performance and durability. In this article, we will explore the common problems that can arise with sheathing and provide practical solutions to address them effectively.

1. Moisture-Related Issues

Moisture-related problems pose a significant threat to the sheathing. Water damage and mold growth are among the most common issues encountered. Improper installation techniques and the absence of moisture barriers can lead to moisture infiltration, resulting in rotting, warping, and deterioration of the sheathing material. To address these problems, it is essential to ensure proper installation by following manufacturer guidelines and utilizing moisture-resistant materials. Additionally, incorporating moisture barriers, such as building wraps or vapor barriers, can significantly reduce the risk of moisture-related damage.

 2. Insufficient Structural Support

Sheathing serves as a crucial component for providing structural support to buildings. Signs of insufficient structural support include sagging, warping, or a compromised load-bearing capacity. These issues may arise due to inadequate sheathing thickness, improper fastening, or subpar construction techniques. To address insufficient structural support, reinforcing the existing sheathing or adding additional layers can enhance its strength and stability. Consulting with a structural engineer can provide valuable insights and recommendations for reinforcing the sheathing effectively.

3. Pest Infestation

Pests like termites and carpenter ants pose a significant threat to the sheathing, as they can cause extensive damage by tunneling through the wood. Signs of pest infestation in sheathing include wood decay, visible tunnels, or the presence of live pests. Regular inspections are essential to detect early signs of infestation. To prevent and treat pest infestations, employing proactive measures such as periodic professional inspections, using pest-resistant materials, and applying appropriate insecticides can safeguard the sheathing from potential damage.

4. Thermal Performance Issues

Sheathing plays a vital role in the thermal performance of a building, affecting energy efficiency and occupant comfort. Common thermal issues include air leakage and inadequate insulation, leading to heat loss or gain. Proper sealing of joints, openings, and penetrations in the sheathing is crucial to address these concerns. Additionally, ensuring the correct installation of insulation materials, such as rigid foam boards or spray foam, and considering insulated sheathing can significantly improve the thermal performance of the building envelope.

5. Structural Movement and Cracking

Structural movement can have a detrimental impact on sheathing integrity. Signs of structural movement include cracks or gaps in the sheathing, which can compromise its ability to provide structural support and protection. To address these issues, reinforcing connections between sheathing panels and using flexible sheathing materials, such as plywood or OSB, with appropriate structural ratings can help accommodate structural movement while maintaining the overall integrity of the sheathing.

6. Maintenance and Inspection Practices

Regular maintenance and inspections are crucial for preserving the condition and longevity of sheathing. Cleaning the sheathing surface to remove dirt, debris, and organic matter can prevent moisture retention and minimize the risk of mold growth. Sealing cracks or gaps in the sheathing and periodically reapplying protective coatings can enhance its resistance to moisture infiltration. Conducting internal and external routine inspections to identify signs of damage, pest infestation, or structural issues can allow for prompt intervention and preventive measures.

However, it is essential to note that when dealing with sheathing issues or roofing concerns, you should seek professional assistance from reputable, experienced roofing companies in OKC, such as OKC Roofers in Oklahoma City. Our professionals can provide specialized expertise, assess the situation, and offer tailored solutions for your roofing and sheathing needs.


The sheathing is vital in the construction industry, providing structural support, protection, and insulation for buildings. However, it is susceptible to various problems, including moisture-related issues, insufficient structural support, pest infestations, thermal performance concerns, and structural movement. By addressing these problems promptly and employing preventive measures, such as proper installation techniques, moisture-resistant materials, regular maintenance, and inspections, the longevity and performance of the building’s sheathing can be ensured. For specific concerns and complex issues, it is recommended to consult professionals with expertise in sheathing to obtain tailored solutions. Remember, prioritizing proper installation and maintenance of sheathing is essential for a durable and resilient building envelope.
