A process for providing asphalt-based roofing products includes the steps of: providing a hot asphalt surface, applying a non-asphalt adhesive to the asphalt surface; and embedding a plurality of roofing granules in a hot asphalt surface. Such a product generally leads to roofing products which are improved with respect to performance, especially with respect to adherence of roofing granules within the product. The invention includes within its scope products comprising asphalt based substrates having roofing granules embedded therein, a non-asphalt adhesive being provided at the interface between the hot asphalt and the roofing granules.
