A roofing product can include a ceramic base material and a recycled roofing material. In a particular embodiment, an open structure of the ceramic base material is filled with a bituminous material that has no greater than approximately 5 weight % of abrasive particles or 0.1 weight % metal content. The recycled roofing material can be disposed along one or both sides of the ceramic base material. The bituminous material may have a characteristic particle size that is smaller than a characteristic particle size of the recycled roofing material. In another embodiment, the roofing product having the recycled roofing material can have tear strength characteristics as compared to a different roofing product having a substantially the same construction but having abrasive particles embedded within the ceramic base material.
