ABSTRACT:
A ridge cover is formed of inorganic (glass) felt-like sheet material fill-coated with an asphaltic material modified to improve its flexibility. The sheet material is repeatedly back bent upon itself to provide a thickened portion for the ridge cover. The flexible asphaltic material surprisingly allows such back bending of the sheet material substantially without fracture of the glass fibers of the inorganic felt at the bends.
