What is a potential drawback of using wood siding?

Wood siding is indeed vulnerable to deterioration, which is the correct point to focus on when considering the potential drawbacks of this material. Over time, wood can be affected by various environmental factors such as moisture, temperature changes, and exposure to sunlight. These factors can lead to issues such as warping, splitting, and rot, particularly if the wood is not properly treated or maintained.

Additionally, wood is susceptible to attacks from various pests including termites, which can further contribute to its decline in structural integrity. Moisture accumulation can also result in mold and mildew growth, complicating maintenance and posing health risks.

In contrast, the other options highlight attributes that generally make wood siding appealing. A long lifespan, for instance, can be characteristic of well-maintained wood siding, and while there are types of wood that offer resistance to insects, wood by nature is not inherently resistant. Lastly, wood can be considered environmentally friendly when sustainably sourced, but this does not negate the inherent vulnerabilities associated with its use in construction.
