The statement is true because, in areas where there is a history of ice formation along eaves, building codes often require an ice barrier as a preventive measure against ice dam damage. This barrier helps prevent water infiltration that can occur when melting snow refreezes at the eaves, potentially leading to leaks within the building structure.

The requirement for at least three layers of underlayment cemented together ensures that the ice barrier is sufficiently robust to handle the stresses caused by ice accumulation, providing enhanced protection compared to a single layer. Proper adherence to local building codes is critical in regions susceptible to winter weather, and this requirement is often codified to ensure safety and performance standards in residential construction.

In contrast, the other options suggest conditions or qualifications that do not align with the building code requirements established for such areas. For instance, the assertion of only needing it if building codes allow disregards the mandatory nature of these codes in relevant geographical locations, and suggesting limitations to new constructions fails to recognize that existing buildings could also benefit from compliance with ice barrier standards in vulnerable areas.
