Double vapor barriers should generally be avoided in building assemblies because they trap moisture, preventing drying and potentially damaging moisture-sensitive components like wood framing. However, there are specific exceptions, such as in unvented roof assemblies, where a double vapor barrier is necessary, provided it also functions as an effective air barrier. To mitigate risks in these scenarios, it is critical to prioritize moisture-tolerant materials and ensure proper design to allow the assembly to remain durable and functional.
