This guide will help you answer all questions about metal roof systems and we’ll explain everything you should know about it.

What is a Metal Roof?

A metal roof is a roofing system made from metal pieces, tiles, or panels characterized by its high resistance, impermeability, and longevity. This is an ancient material that has been used continuously for roofing as well as many other forms of architecture up to today.

It has always been notorious for its function as a superior roofing option as opposed to other materials, regardless of which type is used. However, due to its higher cost, it never really grew popular as a mainstream home option until the past few generations.

Metal Roof Types and Their Advantages

A metal roof brings many advantages to homeowners, from being low maintenance to having a long lifespan. If you’re interested, there are more types of materials and panel styles than you probably realize.

Below are some of the most commonly used metal roofing:

  • Exposed Fastener – An exposed fastener is a type of system in which the fasteners stay visible and not hidden by a seam. In this type of metal roofing, the panels are fastened directly into the deck through the face of the metal. The fastener goes through both layers of panel edges lapping one another. An exposed fastener system can be used on residential, structural, industrial, and agricultural buildings. Talking about the advantages, exposed fastening is less expensive when compared to standing seam systems. It does not require hand or mechanical seaming of the two panels. It gives the roof a unique look and lastly, more contractors have the skills and tools to install it.
  • Standing Seam/Hidden Fastener/Concealed Fastener – Standing seam or concealed fasteners are types of metal roofing systems that have hidden fasteners. It features vertical legs and a broad, flat area between the two legs. The fasteners are driven through the clips into the deck with no connection or piercing of the panels. The clip and fasteners are concealed beneath the standing seam panel material. The panel is then laid over and attached to the clips, before finally being mechanically or hand locked to the clips. Standing seams are one of the higher-quality systems that are popularly used on residential and commercial buildings. Hidden fasteners allow for thermal movement. Since the fasteners don’t penetrate the surface, regular maintenance to check for withdrawing, loose, or damaged fasteners is even less frequent. One of the best parts about standing seam is the option to mount items, such as solar panels, snow retention systems, swamp coolers, or other rooftop additions, without penetrating or making any holes in the surface.
  • Vertical Seam – The vertical seam is one of the most versatile options in the genre of metal roofing. Whether you need it for a home, business, or commercial application; Vertical Seam may fit the bill. Vertical seams are affectionate, and attractive, and allow maximum expansion and contraction in summer and winter. Vertical Seams have 1.75″ high ribs in widths of 12″, 16″, and 18″ apart which makes it easy to be installed over open framing slopes as low as 3:12 and solid decking slopes as low as 1:12.
  • Preformed Panels – Preformed panels are customized metal roofing panels that offer a versatile and affordable way to enhance the external appearance of any building. These types of panels are available in various finishes, module sizes, and thicknesses to suit an array of desired effects and needs. One of the best parts about preformed panels is that they can be customized, you get what you ask for. Depending on the type of roofing needs, you can order your preformed panels.
  • Granular-Coated Panels – A granular-coated or stone-coated panels are metal roofing panels that have a thick layer of stone that permanently adheres to the surface and provides a decorative traditional shingles look. Granular-coated panels have a longer lifespan and can withstand gusting winds, heavy rain or hail, and many other adverse weather conditions. It needs low maintenance compared to asphalt shingles and comes in a wide variety of colors, textures, and designs to complement almost any style.

The Most Commonly Used Material For Metal Roofs

You have plenty of options when it comes to choosing a metal roofing material. Sometimes, it can be tricky to decide which metal roof is best for your home or building. From classic copper to innovative steel, each type of material has its unique advantages.

Let’s explore the different types of materials:

  • Aluminum – Aluminum is one of the most used metal roofing materials in the US. They not only stand up to extremely harsh weather conditions, but it’s one of the most sustainable metals in the world, which is why it has become such a popular choice for structures. Aluminum is lighter, softer, and highly recyclable. The best part about aluminum is the fact that about 95% of all aluminum installed across the world is made from recycled aluminum materials. It’s resistant to rusting, and corroding and is available at a medium price point.
  • Copper – Historical data shows that the Romans used copper covering on the roof of the Pantheon in 27 B.C. Even today, many architectural structures, commercial buildings, and even residential homes use copper panels and coils for roofing. Some of the best things about copper are its lightweight, energy efficiency, durability, and aesthetically pleasing features. Though it’s not as recyclable as zinc, it can be recycled and reused up to some extent if still in good condition.
  • Terne – Terne is mild steel with a coating of zinc and tin alloy to protect the steel from rust. Once the material is formed and installed it gets painted; as long as the paint is kept up once every ten to fifteen years, you are left with a roof that can last a century.
  • Zinc – Similar to copper, zinc can also last up to 80 to 100 years. Zinc is always a great option for residential and business owners looking for a material that is easy to use, has immunity to corrosion, and has other sustainable features. The best part about zinc is its self-healing properties. If wind or another element were to scratch the surface of the zinc metal roof, the materials’ protective layer would actually fix and correct itself over time. Apart from that, it’s known for its longevity, energy-saving, eco-friendly and easy maintenance.
  • Steel – If you’re looking for the strongest, most popular, and least expensive option, steel is the best choice. It is also a green solution because it’s both highly recyclable and easily accessible. Steel comes in three variations: galvanized, galvalume, and weathering steel (Corten). Galvanized is made from steel coated with zinc, which makes it more resistant to corrosion. Galvalume is coated with aluminum, which also increases its corrosion resistance.
  • Stainless Steel – Another great option is stainless steel. It is a steel alloy made up of at least 10.5% chromium. Stainless steels are known for their durability and can withstand extreme weather and temperature climates. It has low thermal expansion properties, comes in a variety of different finishes, and could last 60+ years.

  • Shake – Shakes give your metal roofing the natural beauty of cedar shake roofing for a lifetime. Unlike traditional cedar shakes, metal shakes will never split, warp, mold, or rot, and on top of that, you’ll not require routine maintenance.
