Yes. A study by the Energy Materials Testing Laboratory has shown that EPS insulation installed in well-constructed roofs does not absorb appreciable moisture, even under conditions characteristic of prolonged, cold winters. The small amount of moisture absorbed (an average of 0.02% by weight) has little or no effect on compressive and flexural strength. Further, the EPS insulation retains between 95% and 97% of its thermal efficiency.
