What are granules adhering to newly-produced shingles but not embedded in the asphalt called?

The term for granules that are adhering to newly-produced shingles but not embedded in the asphalt is commonly referred to as "loose granules." These granules are often the result of the manufacturing process and may not yet have fully adhered to the shingle surface.

Loose granules on new shingles can be an indication of a few factors, including the quality of the application of the asphalt and the adhesive properties during the manufacturing process. It's important not to confuse these with "dust," which might imply that the granules are simply very small debris rather than legitimate components of the shingle.

While "hitchhikers" and "fleeces" may sound applicable, they are terms not widely used in relation to roofing materials. Thus, the correct classification for granules that have not embedded properly into the asphalt is indeed "loose granules." Understanding this terminology is crucial for home inspectors when evaluating the condition and performance of roofing materials.
