There are two types of metal roofing that you will commonly see, Corrugated Metal and Standing Seam. Corrugated Metal is cheaper than Standing Seam but it doesn’t last as long. Corrugated metal panel needs to be replaced every 10-15 years while standing seam can last up to 50 or more years with minimal cost for repairs. There are also some aesthetic differences between the two types of roofs which may sway your decision one way or another. If you’re still unsure about what type of roofing to install on your home then please read this article!

Why Choose a Metal Roof?

Metal roofing systems have existed since people first began constructing homes out of stone or wood, but there are now more options than ever before for this sort of material. A metal roofing system is an excellent choice for any home or business that requires a long-lasting, lightweight, and energy-efficient roof. Metal roofing materials are more cost-effective over time since they endure far longer than alternative materials that require less maintenance, such as wood shingles, tiles, or concrete blocks. Furthermore, metal roofs can be pre-coated to prevent dangerous spores from being released into the air you breathe by suppressing mold growth on your property. There are two types of metal roofing, Standing Seam Metal, and Corrugated Metal. Check out our website for more information on Metal roofing at ManhattanRoofingnyc.com.

What is Standing Seam Metal?

A concealed fastener metal panel system with vertical legs and a broad, flat region between the two legs is known as standing seam metal roofing. Raised seams or vertical legs, that rise above the level of the panel’s flat section are also mentioned. Metal roofing, which is the most prevalent application, or metal walls can both benefit from standing seam systems. The most important thing to remember about standing seam systems is that the fastener is hidden, regardless of whether the panel is clipped to the roof deck or directly affixed to the decking material under the vertical leg with a fastener flange.

The diversity of choices and alternatives available to clients is one of the most important selling factors of standing seam metal roofing. These options go beyond the panel’s color to include its length, breadth, profile, form, thickness, and more. Let’s take a look at some of the most common types and applications.

Types of Panel Profiles

The shape and way two or more panels are seamed together are referred to as a panel profile. What profile you should choose with the guidance of a contractor or architect will depend on the sort of roof you have, how steep it is, the environment your property is in, and a variety of other considerations. The standing seam category encompasses a wide range of panel profiles, including:

The Snap-lock Profiles
The Mechanical Lock Profiles
The Batten Panel Profiles
The Nail Flange or Fastener Flange Profiles

The Panel Sizing

In addition to the many profiles available, interior liner panels can be ordered in a variety of sizes or roll-formed on-site. Performance requirements, how well the size fits the profile, and consumer preferences are all factors that influence the size chosen.

Panel Widths
Seam Height
Thickness

Pros of Standing Seam:

The following are some of the advantages of standing seam metal roofing:

Hidden fasteners – A standing seam metal roof’s hidden fasteners are one of its most appealing features. Most metal roofing, such as corrugated metal panels, has exposed screws or fasteners that can corrode over time in harsh weather. Because the fasteners on a standing seam metal roof are hidden, it is resistant to UV radiation, moisture, and wind.
Durable – Even though standing seam metal is lightweight and flexible, its hidden fasteners allow a standing seam metal roof to endure harsh weather and extend its lifespan.
Energy-efficient – Standing seam metal roof panels reflect solar radiant heat, keeping your home cool and perhaps lowering your cooling bills.
Eco-friendly – Standing seam metal roofs are environmentally friendly than corrugated metal since they are composed of recycled materials such as aluminum and can be easily reused.
Rust and Fire-resistant – Standing seam panels are occasionally coated with Kynar, a thermoplastic fluoropolymer that prevents the metal from rusting and being damaged by extreme weather conditions. Kynar-coated panels often come with a limited warranty of up to 40 years.

Cons of Standing Seam

Expensive – Standing seam metal roofing panels are more expensive than asphalt shingle roofs and other metal roofing materials because they must be installed by a professional roofer. They cost twice as much as a normal asphalt shingle roof and more than other metal roofing materials.
Fastener Issues– Problems with fasteners. Exposed fasteners can suffer from a variety of issues, including withdrawal and UV deterioration, depending on the climate and sun exposure.
High-Maintenance – An exposed fasteners must be checked for debris, dirt, sticks, leaves, mildew, and flaking on a regular basis and cleaned.
Aesthetics – For property owners who prefer a sleek and modern aesthetic, it might not be the best option. Roofing with an exposed fastening system gauge is thought to have a rustic appearance.
Noisy – When it rains or storms, a standing seam metal roof might be noisy if your property isn’t adequately insulated.
No waterproofing – There is no waterproofing. The installation of an exposed fastener roof necessitates the creation of several holes that are only hidden by the fastener to which they are attached. The metal will expand and contract over time, changing the size of the holes. It may eventually result in leaks and water damage.

What is Corrugated Metal?

Henry Robinson Palmer, a British engineer, invented corrugated steel in the 1820s. He devised the corrugated steel panel for the London Dock Company so that people with little building experience could swiftly install it. Because it was prefabricated and affordable, it quickly became popular.

Corrugated metal roofing is made out of metal sheets that have been rolled into panels. Screws are then used to secure the panels to the roof slope. Corrugated sheet metal is often circular and wavy in shape. It’s inexpensive, lightweight, sturdy, energy-efficient, long-lasting, and simple to set up. Asphalt shingles or clay tile roofs can be replaced with corrugated metal roofing. It’s used for both commercial and residential projects, as well as metal roofing and siding. Corrugated metal roofing is a bit of a misnomer. Corrugated is the sole term used in the roofing industry to describe an “ S “ shaped wavy panel. To put it another way, it’s everything around and wavy that isn’t square or boxy. The phrase corrugated, on the other hand, can refer to any metal that has been shaped into grooves and ridges. It could refer to any style of metal roofing, including those with a square or boxy appearance.

Pros of Corrugated Metal

Inexpensive – Corrugated metal is inexpensive. This isn’t an issue for all homeowners, but those who are on a tight budget should consider this option.
Lightweight – Corrugated roofs are lightweight and durable which means they’re easy to install without professional help or expensive machinery like cranes.
With insulating layer – Corrugated steel roofing panels also have an insulating layer. This means they can help keep your home warm in winter and cool in the summer.
Fire Resistant – Corrugated panels are also fire resistant, making them a safer option for those living near brush fires or other high-risk areas.

Cons of Corrugated Metal

Corrugated steel is not recommended for properties located in areas of high water, strong winds, and hurricanes. Corrugated steel isn’t waterproof which means that it can leak when the weather gets rough.
Corrugated metal roofing panels are prone to rust if they’re not treated with anti-rust paint or another type of sealant. Corrosion resistance can also be achieved using a galvanized finish. Corrugated metal has been painted since the 19th century, but it needs to be maintained or water will seep into any exposed fasteners and eventually cause corrosion in other areas of the roofing system.
Corrugated roofs might also emit a loud noise when they’re subjected to heavy winds and rain because there’s no roofing membrane to help protect them from the elements.
Corrugated metal roofs are not energy efficient and they can’t be insulated which means your heating and cooling bills will likely go up.

How Much Does a Corrugated Metal Roof Cost to Install?

Corrugated metal roof panels are relatively inexpensive and easy to install, making them a great choice for homeowners who don’t own any tools or have limited building experience. It’s also affordable in comparison with other materials like slate shingles, clay tile roofs, flat-rolled steel sheets, cedar shakes, and asphalt shingles. Corrugated metal roof has a lower price than other metal roofs. Prices range from $0.50 per square foot to $0.80 per square foot, with an average cost of about $0.70-$125 per square foot for a standard size house including labor. Corrugated metal roofs are also easy to maintain and can last up to 50 years if properly cared for. Corrugated metal roofs have been used for centuries and they’re the most common type of roofing in many places around the world.

Conclusion

Metal roofing comes in two different styles: standing seam and corrugated galvanized steel. Both have pros and cons that are worth considering. Whether the panel is clipped to the roof deck or directly secured to the decking material under the vertical leg with a fastener flange, the most essential thing to remember about standing seam systems is that the fastener is hidden. The shape of corrugated sheet metal is frequently round and wavy. It’s low-cost, lightweight, strong, energy-efficient, long-lasting, and easy to put together.
