2. Metal roof - Wikipedia

   en.wikipedia.org/wiki/Metal_roof

   Standing seam metal roofs can have a lower pitch than asphalt shingle roofs because shingled roofs need a higher pitch to keep the wind from blowing up the shingles and potentially blowing them off in high winds. Standing seam metal roofs come in sheets up to or sometimes more than 30 feet (9.1 m) long and widths of 12, 14, 16 or 18 inches (300 ...

   Progressive roller dies of the roof seamer are used to bend the metal roof panel seam into the desired shape to produce a finished seam profile. This shows a cross-section profile of the seam. Mechanically seamed standing seams (double locked) A roof seamer is a portable roll forming machine that is used to install mechanically seamed ...

   Since then, many types of metal roofing have been developed. Steel shingle or standing-seam roofs last about 50 years or more depending on both the method of installation and the moisture barrier (underlayment) used and are between the cost of shingle roofs and slate roofs.

   The PV laminates are adhered to standing seam metal roof panels which are then attached to ground-mounted metal racks at 20 degree angles. [2] The PV laminates are electrically wired in series so that there are twelve 128 Watt PV laminates per string and the overall system has 400 strings, composed of 4,800 PV laminates, for a total of 614 kW ...

6. Rooftop solar power - Wikipedia

   en.wikipedia.org/wiki/Rooftop_solar_power

   With the increasing efficiencies of thin film solar, installing them on metal roofs has become cost competitive with traditional monocrystalline and polycrystalline solar cells. The thin film panels are flexible and run down the standing seam metal roofs and stick to the metal roof with adhesive, so no holes are needed to install. The ...
