What is a Standing Seam Roof?

A standing seam roof is a type of metal roofing system characterized by its vertical legs and flat area between the legs. These roofs are known for their durability, sleek appearance, and excellent weather resistance.


In simple terms, a standing seam roof consists of metal panels that run vertically from the roof ridge down to the eaves. The panels are connected by raised seams, which are typically 1 to 2 inches high. These seams are what give the roof its “standing” appearance.

Concealed Fasteners

One of the standout features of a standing seam roof is its use of concealed fasteners. Unlike other roofing types where screws or nails are visible, standing seam roofs hide these fasteners beneath the panels. This not only creates a cleaner look but also protects the fasteners from the elements, reducing the risk of leaks or corrosion.

Vertical Legs

The vertical legs in a standing seam roof are the raised portions where the panels interlock. These legs provide structural integrity and help direct water away from the seams, enhancing the roof’s water-tightness. The height of these legs can vary but is generally between 1 to 2 inches.

Trapezoidal Legs

Some standing seam roofs feature trapezoidal legs, which are wider at the base and taper towards the top. This design adds extra strength and stability to the roof, making it even more resistant to wind and other harsh weather conditions.

Standing seam roofs are not just practical; they also add a modern, sleek look to any building.

Whether you’re considering a standing seam roof for its durability, aesthetic appeal, or both, understanding its components can help you make an informed decision. Now that we’ve covered the basics, let’s dive into the different types of standing seam roofs and their unique features.

Types of Standing Seam Roofs

Standing seam roofs come in various types, each with unique features and benefits. Let’s explore the main types: snap-lock panels, mechanically seamed panels, double lock seam, symmetrical seam, one-piece snap-lock interlock, and two-piece snap-lock interlock.

Snap-Lock Panels

Snap-lock panels are designed for easy installation. They snap together by hand with the help of clips that attach to the roof deck. These clips allow for thermal movement, which means the panels can expand and contract with temperature changes without causing damage.

Ease of Installation: Snap-lock panels reduce labor time and costs.
Thermal Movement: Clips allow the panels to move with temperature changes, minimizing stress on the roof.

Mechanically Seamed Panels

Mechanically seamed panels are similar to snap-lock panels but require a bit more effort to install. These panels are crimped together using a machine or by hand, creating a watertight seal.

Durability: The crimping process makes these panels particularly watertight and durable.
Weather Resistance: Ideal for areas with harsh weather conditions.

Double Lock Seam

Double lock seam panels take weather-tightness to the next level. The seams are folded twice, providing extra durability and making them highly resistant to water infiltration.

Extreme Durability: Double folding ensures a strong, long-lasting seal.
Weather-Tight: Excellent for climates with heavy rain or snow.

Symmetrical Seam

Symmetrical seam panels offer flexibility in installation and maintenance. These panels can be replaced individually without disturbing the adjacent panels, making repairs easier.

Panel Replaceability: Easy to replace individual panels without affecting the entire roof.
Flexibility: Suitable for complex roof designs.

One-Piece Snap-Lock Interlock

One-piece snap-lock interlock panels are designed for straightforward installation. The panels interlock in a single piece, making the installation process quicker and simpler.

Ease of Installation: One-piece design speeds up the installation process.
Interlock System: Provides a secure fit, reducing the risk of leaks.

Two-Piece Snap-Lock Interlock

Two-piece snap-lock interlock panels offer enhanced security. These panels interlock in two pieces, providing a more secure fit and additional resistance to wind and weather.

Enhanced Security: Two-piece design offers extra stability and resistance.
Interlock System: Ensures a tight, secure fit, ideal for high-wind areas.

Each type of standing seam roof has its own set of benefits, making it essential to choose the right one based on your specific needs and environment. Whether you prioritize ease of installation, durability, or weather resistance, there’s a standing seam roof that’s perfect for your project.

Now that you understand the different types of standing seam roofs, let’s explore their various applications in residential, commercial, and other settings.

Applications of Standing Seam Roofs

Standing seam roofs are versatile and can be used in many different settings. Let’s explore their applications in residential, commercial, recreational, architectural, and coastal areas.

Residential Applications

Standing seam roofs are becoming popular for homes. They offer curb appeal and durability that many homeowners desire. Rafael C. from New York shared his excitement about the installation of his new ClickLock standing seam roof, praising the customer service and responsiveness of the company.

These roofs are designed to last up to 60 years, making them a long-term investment. They can withstand harsh weather conditions and require minimal maintenance, making them ideal for homeowners looking for a long-lasting and aesthetic solution.

Commercial Applications

For commercial buildings, standing seam roofs offer low maintenance and a long lifespan. These roofs are designed to handle the wear and tear that comes with commercial use. They are also fire-resistant and can be installed over existing roofing, reducing waste.

Businesses can benefit from the cost-effectiveness of these roofs in the long run. The initial investment may be higher, but the durability and minimal maintenance required can lead to significant savings over time.

Recreational Applications

Recreational buildings, such as sports facilities and community centers, can benefit from the aesthetics and structural soundness of standing seam roofs. These roofs provide a sleek, modern look that enhances the appearance of any recreational facility.

Moreover, the durability of standing seam roofs ensures that these buildings remain protected from harsh weather conditions, ensuring the safety and comfort of their users.

Architectural Applications

In architectural projects, standing seam roofs are often chosen for their high visibility and clean lines. These roofs can be customized to fit the specific design requirements of any project, making them a popular choice for architects.

The concealed fasteners and smooth appearance of standing seam roofs add a modern touch to any building. This makes them ideal for projects where aesthetics are a top priority.

Coastal Areas

Coastal homes face unique challenges, such as high winds and saltwater corrosion. Standing seam roofs, especially those made from aluminum, are perfect for these environments. They offer wind resistance and high strength, ensuring that the roof remains intact during storms.

Aluminum standing seam roofs are less likely to rust or corrode, making them an excellent choice for coastal areas. Homeowners in these regions can enjoy the durability and low maintenance of these roofs while also benefiting from their sleek, modern appearance.

Now that we’ve covered the various applications of standing seam roofs, let’s dive into their advantages and how they can be a smart investment for different types of buildings.

Advantages of Standing Seam Roofs


Standing seam roofs are known for their exceptional durability. Made from high-end steel or aluminum, these roofs can last up to 60 years. This longevity is especially beneficial in areas with extreme weather conditions, as they can withstand high winds, heavy rain, and even snow.


One of the key advantages of standing seam roofs is their weather-tight design. Thanks to their concealed fasteners and raised seams, there are no exposed screws that could potentially allow water to penetrate. This makes the roof watertight and highly resistant to leaks, ensuring your home stays dry and protected.

Low Maintenance

Another significant benefit is that standing seam roofs are virtually maintenance-free. Once installed, the only major maintenance required is occasional checking around penetrations like vent pipes. Minimal upkeep means fewer worries and lower long-term costs. Annual checks can help catch potential issues early, ensuring your roof remains in top condition for years.

Long Lifespan

A properly installed standing seam roof can last between 30 to 50 years. The Kynar 500 finish applied to the metal panels not only protects against the elements but also prevents the color from fading. This means you won’t have to worry about frequent replacements or repairs, making it a cost-effective option in the long run.

Aesthetic Appeal

Standing seam roofs offer a modern look with sleek lines that significantly enhance a home’s curb appeal. Unlike traditional roofing materials, these roofs provide a clean, contemporary aesthetic that can elevate the overall appearance of any building. Whether used on residential or commercial properties, standing seam roofs add a touch of elegance and sophistication.

Next, we’ll explore the potential disadvantages of standing seam roofs to give you a complete picture before making your decision.

Disadvantages of Standing Seam Roofs

When considering a standing seam roof, it’s crucial to weigh the potential drawbacks. Here are some of the main disadvantages:


The most significant downside is cost. A standing seam metal roof can be three times more expensive than traditional asphalt shingles. For instance, while architectural asphalt shingles might cost around $4.76 per square foot, a standing seam metal roof can set you back about $15.00 per square foot. This steep price can be a deal-breaker for many homeowners.

However, remember that this higher upfront cost often translates into long-term savings due to the roof’s durability and low maintenance needs.


Another common concern is noise. Rain hitting a standing seam metal roof can create a noticeable echo. This is especially true during heavy downpours. While solid roof decking and wood fiber insulation boards can help absorb some of the sound, they won’t completely eliminate it. If you live in an area with frequent rainfall, this could be a significant consideration.

Oil Canning

Oil canning is an aesthetic issue that can affect standing seam metal roofs. It occurs when panels are fastened too tightly, causing them to show a bubbling or wavy look. While oil canning doesn’t impact the roof’s functionality, it can detract from its visual appeal. If curb appeal is a priority for you, this is something to keep in mind. Proper installation and allowing room for metal expansion can help mitigate this issue.

Next, we’ll explore the installation process to give you a better understanding of what to expect if you decide to go with a standing seam roof.

Installation Process


Before installing a standing seam roof, proper preparation is crucial. The process begins with inspecting and repairing the roof deck. Any damaged areas must be fixed to ensure a solid foundation for the new panels.

Next, an underlayment is installed. This layer provides extra protection against water infiltration. It’s like a waterproof blanket that shields your roof deck from moisture.

Measurements are also vital. Accurate measurements ensure that the panels fit perfectly, reducing waste and ensuring a seamless look.

Panel Attachment

Once the preparation is complete, it’s time to attach the panels. This step involves using clips and fasteners. Clips are used to secure the panels to the roof deck while allowing for thermal movement. This is important because metal expands and contracts with temperature changes.

Alignment is key during this stage. Proper alignment ensures that the panels are straight and evenly spaced, contributing to the roof’s overall appearance and functionality.

Seaming Methods

There are two main seaming methods: snap-lock and mechanical seaming.

  • Snap-Lock: This method uses clips to secure the panels. The panels snap together, creating a tight seal. It’s quicker and easier to install, making it a popular choice for many projects.

  • Mechanical Seaming: This method involves crimping the panels together, either by hand or with a machine. It creates a more secure and weather-tight seal, ideal for areas with extreme weather conditions.

Quality Control

Quality control is the final step in the installation process. This involves thorough inspection and testing to ensure the roof is weather-tight and meets all building codes.

Inspectors check for proper alignment, secure fasteners, and any potential issues like oil canning. They also test the roof’s water resistance to ensure it can withstand the elements.

By following these steps, you can ensure a durable, long-lasting, and visually appealing standing seam roof.

Next, we’ll dive into the frequently asked questions about standing seam roofs to address common concerns and provide more insights.

Frequently Asked Questions about Standing Seam Roofs

A standing seam roof is known for its impressive durability. When properly installed, these roofs can last 50 years or more. Some high-quality options, like those made from aluminum or steel with a Kynar 500 finish, can even stretch up to 60 years. This long lifespan makes standing seam roofs a great long-term investment for homeowners.

How much does a standing seam roof cost?

Standing seam roofs are more expensive than traditional roofing options like asphalt shingles. On average, you can expect to pay around $15.00 per square foot. This is roughly three times the cost of architectural asphalt shingles, which average about $4.76 per square foot. While the initial cost is higher, the long-term savings on maintenance and energy efficiency can offset the upfront investment.

Can standing seam roofs be installed on low slopes?

Yes, standing seam roofs can be installed on low slopes. These roofs are versatile and can handle various roof pitches. The interlocking panels and concealed fasteners make them particularly suitable for low-slope applications because they provide excellent water resistance.
