Understanding Wood Warping

Wood warping refers to the deformation or distortion of wood due to changes in moisture content, temperature, and humidity. Several factors influence wood warping, including the type of wood species used for construction.

Cedar Wood and Warping


Redwood, known for its natural resistance to warping, is an ideal choice for exterior applications.

Cedar Wood

Cedar wood, similarly to redwood, possesses inherent qualities that make it resistant to warping. However, it is not entirely immune to warping under certain conditions.


Fir wood, although less resistant to warping compared to redwood and cedar, can still be suitable for outdoor use when properly maintained.

Effective Strategies to Prevent Cedar Warping in Rain

Properly Drying or Curing the Cedar Wood

Before using cedar for exterior applications, it is crucial to ensure that the wood is properly dried or cured. This process helps stabilize the wood’s moisture content and reduces the likelihood of warping when exposed to rain.

Conducting Regular Inspections for Warping and Moisture Content

Periodic inspections of your cedar exteriors are essential to detect any signs of warping or excessive moisture content. Promptly addressing these issues can prevent further damage and maintain the integrity of the wood.

Identifying Signs of Wood Warping

Regularly checking for signs of wood warping, such as bowing, twisting, or cupping, is crucial for early detection and intervention. Timely action can help prevent further warping and ensure the longevity of your cedar exteriors.

Addressing Weaknesses in Cedar Exteriors

Identifying and addressing weaknesses in cedar exteriors, such as loose boards, gaps, or structural instability, can prevent warping caused by rain. Reinforcing weak areas and ensuring proper installation can enhance the resistance of cedar wood to warping.

Recommended Practices for Preserving Cedar Exteriors

Implementing recommended practices for preserving cedar exteriors, such as applying protective finishes or sealants, can enhance the wood’s resistance to moisture and reduce the risk of warping in rainy conditions.

Minimizing Fading and Checking in Cedar Wood

In addition to warping, cedar wood can also experience fading and checking (cracking) when exposed to rain. Proper maintenance, including regular cleaning and applying UV-protective coatings, can minimize these effects and prolong the life of your cedar exteriors.

Considering the Costs of Preventing Cedar Warping

While the prevention of cedar warping in rain involves upfront costs, such as proper wood treatment and maintenance, it is a worthwhile investment to preserve the beauty and durability of your cedar exteriors in the long run.


By understanding the factors contributing to wood warping and implementing effective strategies, you can prevent cedar exteriors from warping in rainy conditions. Properly drying or curing the wood, conducting regular inspections, addressing weaknesses, and following recommended preservation practices will help maintain the integrity and aesthetics of your cedar exteriors for years to come.
