   The Roofing Practices Manual (RPM) is the official guide for RCABC Members, Accepted Inspectors, designers, architects and specification writers designing or applying roofing and waterproofing systems, and describes the RoofStar Guarantee Standards, Guiding Principles and Recommended Practices necessary to qualify for a RoofStar Guarantee.  The RPM meets or exceeds the current national and provincial standards for construction and wind uplift design resistance.  It also includes
   * Materials accepted for the RoofStar Guarantee Program
   * Construction details
   * Design guidelines
   * Best Practices
   * Reference materials
