Installers of Metro Roof panels and accessories should have knowledge of roof structures, an understanding of how to work with stone-coated steel panels and accessories, and be experienced at working on sloped roofs. Metro recommends installers of Metro Roof products use a Metro Cutter, and have completed a SMART-Start On Site installer Training Orientation Program for each profile installed. Metro does not consider its products to be do-ityourself (D.I.Y.) mainly due to specialized cutting & bending tools used during installation. Incorrect Page 7
general - preperation Metro panels are installed on new or existing roofs pitched a minimum of 2-1/2:12 ( 12 degrees). An underlayment is to be installed as per local code and manufacturers instructions. Ice and Water Shield should be installed per product application instructions in areas where icing may occur. Panel battens Panel battens are installed parallel to the ridge/fascia spaced 14 1/2 o/c. Position the first batten flush with the fascia or batten Buildup. The second batten is positioned 14 to allow adequate overhang at the fascia for gutter/water shed from the roof. Valley battens are spaced to accommodate the valley metal Use 2 x2 ridge battens or double stack 1 x4. to provide 1-1/2 fold-up height for hip and ridge. Hip battens install directly on top of each intersecting panel batten, so panel hip cuts can be fitted against hip battens. Space 5 apart. Panel batten spacing is critical because panel must fit snuggly against the batten. Panel battens may be either 1X4, 2X2 wood (Douglas-Fir / Larch #2 or better) or 1X2 plastic battens. Steel hat sections with a minimum height of 3/4-inch, and 0.017-inch thick (0.43mm) galvanized steel. Page 8

counter battens Counter battens (1 x4 ) are used when roofing over uneven surfaces or where a cold roof installation is desired. Fascia buildup for roofing over existing roofs when reroofing over wood shingles or shakes, the existing roof is cut back around the perimeter to allow a buildup of 1 x4, 2 x2 or a combination of both, to provide a solid fastening foundation. The wood buildup conforms to the underside of the 1 x4 counter battens on top of the existing roof. Consult local codes for the other specific requirements. Position 1 x4 counter battens approximately 24 o/c directly over the rafter. Fasteners must penetrate 1 into or through the roof framing members and be placed 12 o/c. Fascia Metal - drip edge metal Fascia metal is available in either 3 1/2 or 5 face widths to cover the build-up of the new lumber at the fascia and to act as a metal drip edge. Fascia Metal Fascia 1st row support battens vary by region, alternative 1st row 3/4-inch riser options can be; 1X4 wood or plastic battens, Metro Gutter Riser, or Cobra mesh material. Page 12
