  • Low-cost highly aesthetic and durable shingle
    Patent number: 5365711
    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.
    Type: Grant
    Filed: April 28, 1993
    Date of Patent: November 22, 1994
    Inventors: Joseph E. Pressutti, George E. Conley, Alvis M. Rawlinson
