It will help you make a wise decision on which type is right for your needs. This article also discusses the different types of warranties for these roof panels.
Standing seam
The process of installing standing seam steel roof panels is an excellent way to increase the energy efficiency of your home. This type of roofing requires a professional metal fabrication shop that manufactures the panels. Beacon Supply and ABC Supply sell sheet metal panels to contractors, and you can purchase the materials yourself or have them purchased by a professional. The cost of materials for medium to large orders is approximately $5.00 per square foot, with a slightly higher price for larger orders you can find out more
Corrugated
Corrugated steel roof panels are a versatile roofing solution. The wavy profile of 4.2 corrugated panels makes them suitable for almost any application. Unlike standard 2-1/2” corrugated panels, the 4.2 is deeper and can span a greater distance. Originally used in asbestos replacement panels, 4.2 corrugated panels are available in many different sizes and materials. Standard galvanized sheet is available in eight-foot, ten-foot, and twelve-foot lengths her response.
Stone-coated
Stone-coated steel roof panels mimic the look of various types of tiles by using a mix of pigments similar to those found in paint. This mix is then applied to the stone and baked at high temperatures, creating a durable, waterproof coating. Because of the stone-coating process, the final appearance is highly dependent on the pigments used. To ensure a consistent look, multiple color readings are taken at various stages of the manufacturing process.
Exposed fastener
A typical exposed fastener metal roof has side and end laps. These are usually sealed with butyl tape. Screws used in this style of roofing are made from a special type of wood and are gasketed. Unlike the fasteners in traditional roofing systems, the screws used in an exposed fastener system have a larger diameter than most metal screws. This helps prevent the penetration of water through the panels.
Cost
When choosing steel roof panels, many factors come into play, including the manufacturer and the type of seaming. Mechanical and tee seams are more expensive and labor-intensive, as seamers must bend the metal edges. Flashing zones, or extra metal, are often added for weather-tightness, and are typically added around chimneys, skylights, and valleys. In addition, a manufacturer’s warranty will usually require that penetration points be pre-welded.
