Metal Roofing Components Definitions
- Accessories Accessories are the additional components needed to complete a metal roof installation. This includes fasteners, clips, underlayment, sealant, pipe boots, and anything else beyond the metal panels that make up a roofing system.
- Metal coils & sheets Metal coils are long, continuous metal rolls that have been treated and/or coated with a paint system. All metal roofing starts out as coil, which is then rolled out, processed , and then rollformed into panels for installation.
- Panels Panels are rollformed pieces of a metal coil that have been shaped into the desired profile/ribbing structure and are ready to be connected or seamed together to form a metal roof.
- Profile The shape that the metal panels are formed into. The profiles are what determine how the panels fit, connect together, and are attached to the structure.
- Rollforming machinery/equipment The machinery, either in-plant or portable, that forms and shapes the coil into individual panels.
- Seam The side rib at which two metal panels come together and are connected. Seams are formed using a rollformer and are then snapped or mechanically seamed together.

Cons Of Stainless Steel Roofing
No substrate warranty One of the significant drawbacks to stainless steel is that it doesnt carry a substrate warranty. Remember that a stainless steel roof may perform well if handled and installed correctly, but it doesnt come with that additional guarantee in the form of a substrate warranty.
Expensive The cost of stainless steel is in line with the price of zinc and copper, making it a high-end metal roofing choice. Stainless steel roofing can cost anywhere from $500 to $1,300 per roofing square , depending on the finish, panel type, and thickness.
Expansion and contraction concerns In climates with striking temperature differences, stainless steel roofing systems expand and contract during heating and cooling cycles . Your contractor should ensure that your system can accommodate this thermal movement.
Not recommended where there is standing water Roofing made with stainless steel, especially if its in contact with other non-stainless steel metals, requires adequate draining methods to remain durable and functional. Too much standing water on stainless steel can act as an electrolyte and cause galvanic corrosion.
Tin Roofing Pros & Cons
Tin Roofing is an often-requested item by enthusiasts around the United States and Canada. The term “tin roofing” is used interchangeably with metal roofing, steel roofing, or galvanized steel. In fact, tin is actually a rarely used type of metal for roofing. Tin itself is an element, like Copper or Zinc. Tin was introduced as a canning material, which was then adapted by rural DIYers who flattened out the material and used it as a shingle when other materials were not available.
When Aluminum became the standard for containers, which replaced tin roof sheets, so went the use of it as a DIY building material. In reality, when you hear reference of “tin roofing” in modern times, this is normally referring to either a galvanized steel or aluminum material rather than actual tin roof sheets.
For its DIY use in the 19th century, and its ability to remain a part of our vernacular long after it left, Tin Roofing could be fondly considered the Willys Jeep of roofing. While it still has many uses in science and technology, Tin is no longer generally used as a building material option and tin roof sheets have been virtually phased out.

What To Look For In Steel Roofing
A high-quality steel roof can meet the needs of homeowners who have a modest budget and realistic expectations of the roofs functional and cosmetic life.
- Experienced Installer: Choose a reputable, experienced steel roofing installer. Although highly durable once installed, steel roofing must be handled with care during installation to avoid dents and scratches.
- Galvanized Steel: Go with Galvanized steel roofing products, not galvalume. Galvanized steel offers more protection from rust than cheaper galvalume products
- Warranty: Read your warranty carefully! Many 50-year steel roofing warranties do not actually cover rust formation where steel has been exposed during the installation process. Learn more about metal roofing warranties.

Stainless Steel Metal Roofing
Stainless steel is an iron alloy made up of at least 10.5% chromium and contains other elements and metals/materials to obtain desired properties.
When people think of stainless steel, they often think of large architectural structures such as elevators, bridges, building columns, handrails, etc. Or perhaps their kitchen appliances, cutlery, cookware, or beyond.
However, stainless steel is also an option in the metal roofing industry primarily because this material is known for its strength which makes it a high-end specialty metal that could be the right material choice for some projects.

Pros Of Copper Roofing
Lightweight Compared to different metal substances and other roofing materials such as shingles, concrete, or tiles, copper is extremely lightweight. Not only does this make it easier for installers and contractors to work with, but it also puts less stress on the structure of a home over time.
Durability Copper is a durable element and can withstand numerous decades as a roof. If properly installed, copper roofing can last 100+ years in some instances. Copper also works well in locations with heavy snow, frequent rainfall, and strong winds.
Aesthetically pleasing Copper is often referred to as a premium roofing material, as it enriches the outside of a building and adds a metallic reddish-orange/brown focal point to a structure. As the copper ages, it develops a blue-green covering called patina, which happens because of oxidation and sun exposure. Many building owners specifically buy copper because of how it ages and adds to the curb appeal of a structure over time.
Highly recyclable Though not as recyclable as zinc, copper can be recycled and reused if still in good condition. Copper is also a naturally sourced metal and can be used in its original mined metallic form.
Solderable Copper can be soldered, unlike other roofing materials. This means roof/wall flashings and gutter joints can be weather-tight with a soldered connection.
Standing Seam Profile Options
Snap-lock Metal roofing panels that have been carefully rollformed with specific panel profile edges that snap together and require no hand or mechanical seaming during installation. Snap-lock seams tend to be a little more popular in the roofing industry because they are engineered to defend against the elements while making installation a little easier on the contractor.
Mechanical seam Mechanically seamed panels are also rollformed with specific edges that line up with each other on the roof. Once the two edges are put together, a hand or robotic seamer is used to bend the edges and lock the panels together. The locked seam resembles the shape of a paper clip. There are two kinds of mechanical seaming:
- Single lock / 90-degree seam one fold of the seam
- Double lock / 180-degree seam two folds of the seam
Tee panel A type of standing seam where the two panels come together and are connected at the top by a cap, which is then mechanically seamed in place to lock the panels together. Once the seaming is complete, the top of the standing seam is in the shape of a T.
Nail/fastener flange Nail flange is similar to a snap-lock panel system, but instead of using a clip to attach the panel to the roof deck, its directly fastened down to the deck through the male leg of the metal panel. Once the fasteners are in place, the female leg of the panel snaps over the entirety of the male leg, which hides the fastener head.

Different Types Of Metal Roofs
Galvanized steel and corrugated galvanized iron are some of the popular materials used for metal roofing. Stainless steel is also preferred by users for its stain-free quality.
Aluminum roofs are also used for metal roofing, because of its lightweight and corrosion-resistant nature. Copper and stone-coated steel are also used as metal roof materials.
Copper roofs are popular among consumers for their durability.
Copper Roofing Pros & Cons
Considered to be the grandfather of metal roofing, copper roofs have been used for centuries around the world. Copper is an extremely long-lasting metal that in ideal environments, can last well over 200+ years. Copper roofs are 100% recyclable too, making them wonderful green roof options.
Copper is an extremely soft metal, which makes it among the quietest types of metal roofing. However, with modern installation practices, all metal roofing now recommends proper substrates and insulation that minimize noise from rain or hail at the same level. The softer nature of Copper Roofing also means that in hail prone regions, it may be easily damaged. As a softer metal, hailstones will easily dent the copper. While this lowers the aesthetic value, it also performs better than a harder metal that, with a large enough hailstone, will puncture rather than simply dent the roof.
If metal roofs are the SUVs of roofing, copper roofs are the Range Rovers of their class. This brings up an apparent downside to copper. Like the Range Rover, it is extremely expensive and depending on your needs, may be more than you need to get the job done. Another negative aspect of copper is its tendency to expand and contract with swings in temperatures. While this can be controlled with the proper panel or shingle, it does need to carefully be considered when choosing this metal.
