The term that accurately describes the process of making a roof waterproof is "dry in." This phrase refers to the practices and techniques used to ensure that a roof is effectively sealed against water intrusion before the final roofing material is installed. It indicates that the roof structure is protected from rain and moisture, which is crucial for preventing leaks and damage to the underlying materials and the interior of the building.

The term "dry in" specifically denotes the preliminary stage where protective measures, such as underlayment or sheathing, are applied to stop water penetration. It is an essential step during roofing installation to ensure that the roof is functional and weather-resistant during the construction process and before the application of the roofing material.

While "waterproofing" may sound relevant, it encompasses a broader range of techniques for making various materials impervious to water, not limited to roofing. "Sealing" is another related term that deals specifically with filling gaps or seams to prevent leaks but doesn't capture the whole process of making a roof waterproof as comprehensively as "dry in." "Roofing," on the other hand, refers to the entire activity of installing a roof, which includes but is not limited to the waterproofing aspect.
