There are 3 basic types of metal roofing in Central Illinois:
Low Rib Panels
Low Rib Panels is a traditional metal roofing system where the panels are mechanically attached with exposed fasteners. These panels are commonly used in the agricultural market and are usually offered at most big box stores.
Low Rib Metal Roof [loh] [rib] [met-l] [roof] or Exposed Fastener [ik-spohzd] [fas-uh-ner] – commonly used on residential properties. Low rib metal has smaller ribs and have less industrial look. Exposed fastened panels use a screw or nail to secure the metal roofing panels to the roof deck or purlins where by the nail or screw actually penetrates an area where two panels overlap.
These panels are installed using concealed fasteners. This is the most common panel for the commercial marketplace as well as residential applications. This provides a nice clean appearance when finished.
Standing Seam Metal Roof [stand-ding] [seem] [met-l] [roof] or Concealed Fastener [Kuhn-seeled] [fas-uhner] – is long sheets of painted steel. This system features interlocking seams that connect panels giving the roof a distinct appearance. Concealed clip fasteners are driven through clips into the roof deck with no connection or piercing of the metal panels. The clip and fasteners are concealed beneath the standing seam panel material. The panel is then laid over and attached to the clips and then mechanically or hand locked to them.
Metal Shingles are rapidly becoming a very popular product across the country to achieve the most durable roof with many different styles to choose from to mimic the look of other materials—from woodshakes, to traditional shingles, to tiled roofs.
Stone Coated Metal Roofing [stohn] [koh-tid] [met-l] [roof] – is made from steel or some other metal; the metal is then coated with stone chips. The goal is a more durable roof that still retails the aesthetic advantages of a more traditional roofing material.
