Introduction: The instructions and drawings included here are intended only as a guide for the installation of DECRA Roofing Systems’ Tile, Shake and Shingle Plus profiles. The materials and methods specified help maintain the overall integrity of the roofing system. These instructions are not intended to address all aspects of roofing installation; a quality installation is ultimately dependent upon the workmanship of the roofing contractor. Information regarding alternative situations not covered in these instructions can be obtained by contacting DECRA Roofing Systems. Safety: Adhere to recommended safe roofing practices. Wear appropriate clothing and use safety equipment, such as protective eyewear. Light, soft-soled shoes are recommended. Use proper tools and keep the roof clear of debris as you work . Tools: DECRA panels may be cut using a cutter/guillotine, tin or aviation snips, or a circular saw using metal-cutting blades. A portable brake (combined bender) or hand bender is recommended to bend the panels for hips, ridges and valleys. Safety equipment should be worn during the installation process. Estimating Sheets: Both the DECRA Estimating Sheet (With Battens) and the DECRA Estimating Sheet (Without Battens) are available at www.decra.com. 2 General Installation www.decra.com
