2. List of commercially available roofing materials - Wikipedia

   en.wikipedia.org/wiki/List_of_commercially...

   Standing-seam metal roof with concealed fasteners. Mechanically seamed metal with concealed fasteners contains sealant in seams for use on very low sloped roofs, suitable for roofs of low pitch such as 0.5/12 to 3/12 pitch. Flat-seam metal with or without soldered seams. Steel coated with a coloured alloy of zinc and aluminium. Stone-coated ...

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 ...

4. Building-integrated photovoltaics - Wikipedia

   Metal pitched roofs (both structural and architectural) are now being integrated with PV functionality either by bonding a free-standing flexible module [15] or by heat and vacuum sealing of the CIGS cells directly onto the substrate [16] Façade. Façades can be installed on existing buildings, giving old buildings a whole new look.

   The following section contains the most commonly utilized components of a rooftop solar array. Though designs may vary with roof type (e.g. metal vs shingle), roof angle, and shading concerns, most arrays consist of some variation of the following components Solar panels produce carbon free electricity when irradiated with sunlight.

6. Roof seamer - Wikipedia

   en.wikipedia.org/wiki/Roof_seamer

   A roof seamer is a portable roll forming machine that is used to install mechanically seamed structural standing-seam metal roof panels, as part of an overall metal construction building envelope system. The machine is small and portable to be handled by an operator on top of a roof.
