2. Roof seamer - Wikipedia

   en.wikipedia.org/wiki/Roof_seamer

   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 ...

3. 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 ...

   hemming process A closed hem A seam. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Hemming is the process in which the edge is rolled flush to itself, while a seam joins the edges of two materials.

5. 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 ...

6. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   If the roof is already constructed, it is relatively easy to retrofit panels directly on top of existing roofing structures. For a small minority of roofs (often not built to code) that are designed so that it is capable of bearing only the weight of the roof, installing solar panels demands that the roof structure must be strengthened beforehand.

7. Architectural metals - Wikipedia

   Today, galvanized steel and pure zinc material, usually Double Locked Standing Seam panels, are used for roofing a variety of buildings. Creep has been reduced by the introduction of titanium in most architectural zinc available in North America. Galvanized nails and sheet metal ducts are also common. Architectural grade zinc is 90 to 95% recycled.
