  48. 48. Metal Tiles & Shingles• The shapes areinfinite, combining roll formingand stamping techniques manyprofiles exist. Labor costs have tobe considered, and gauges shouldbe checked to make sure codesare met.• Metal tiles can be engineered toattain higher wind loads thantheir clay counterparts.
  49. 49. Pitch Limitations / Panel Lengths• Most metal roofing systems are designed to be used on pitches of3/12 and greater.• If you have areas of your roof that are less than 3/12 either changethe pitch, specify a flat roof material, or specify a low slope metalroof system (may add labor costs).• If your project has long rafter runs requiring long metal roofingpanels spec a system with concealed fasteners that has allowancefor panel movements.• If your project has many short panel lengths and intricate detailsdon’t use a field seamed panel as installers will have to hand seammost of the job. Specify a snap-seam and consider aluminum.
