Components of a Standing Seam Roof

More than just visible metal panels, the standing seam metal roof includes various additional features and benefits. Functioning as a comprehensive system, each component contributes significantly to its durability and functionality. The foundation of these roofs is the roof decking, typically made from plywood or OSB, which supports all other roofing components. Over this, a high-heat ice and water shield underlayment is applied to enhance protection from water-related damage.

Metal panels stand as the primary exterior element of the roof. These panels are attached to the lock strip at the rake edge using a locking mechanism and fastened using clips. The standing seam metal roofing panels are uniquely attached using concealed fasteners that allow for natural thermal movement.

Additional components like lock strips, Z bar flashings, and ridge caps all play their part in ensuring the roof’s durability and weather resistance. Overall, the intricate design and interaction of these components contribute to the superior performance of standing seam metal roofs.

Types of Standing Seam Roofs

Not all standing seam metal roofs are identical. Three main classifications exist for these roofs:

  1. Snap-lock systems: These feature concealed fasteners with male and female legs that snap together for simple installation of snap lock panels.

  2. Mechanical lock systems: These require a powered seaming machine to engage the panels.

  3. Batten seam systems: These use vertical battens to secure the panels in place.

The standing seam panels themselves can also vary. They can be symmetrical or asymmetrical. Symmetrical panels are identical on both sides, allowing for ease of installation and repair, whereas asymmetrical panels must be installed in sequence. Your choice between these types can also have economic implications, with fastening flange panels being more budget-friendly but less suited for projects requiring weathertight warranties.

The takeaway? Understanding the types of standing seam roofs can help you make an informed decision that suits both your aesthetic preference and budget.

  • High reflectivity, capable of reflecting up to 70% of the sun’s energy back into the atmosphere

  • Cooler home during the warm months

  • Significant savings on energy costs

Certain types of metal, like aluminum and copper, can further enhance energy efficiency. Aluminum roofing, for instance, does not absorb as much heat as steel and cools down more rapidly, potentially reducing a home’s heating and cooling costs by 20%. Copper roofs, with their natural ability to absorb and radiate less heat, deflect sunlight and save on energy bills through their innate reflective properties.

Undoubtedly, standing seam metal roofs are an eco-friendly choice, offering benefits to both the environment and your finances.

Energy Efficiency

Despite the numerous advantages of standing seam metal roofs, potential drawbacks must also be taken into account. The most significant concern for many homeowners is the cost. Standing seam metal roofs are approximately three times more expensive than architectural asphalt shingles. The cost per square foot can reach around $15.00, which is substantially higher than the approximate cost of $4.76 per square foot for asphalt shingles.

Another possible drawback is noise. During rainstorms, metal roofs can produce noise, although this is generally undetectable to most humans as they cannot distinguish between sounds less than eight decibels apart. However, this can be mitigated with proper insulation and a solid roof deck.

It’s important to balance these disadvantages against the numerous benefits when contemplating a standing seam metal roof.

Initial Cost

Compared to traditional roofing materials, the initial cost for a standing seam metal roof is higher. The national average cost is $29,000, but it can range from $18,000 to $41,000 depending on various factors. Costs per square foot generally range from $5 to $26, influenced by the choice between affordable and high-end metal materials.

The size of the roof and the specific types of metal roof panels chosen are primary factors that influence the overall cost. Additionally, the removal and disposal of old roofing materials can cost between $1 to $5 per square foot, adding to the total expense of the installation.

While the initial cost may seem high, it’s important to consider it as a long-term investment, with the roof’s longevity and minimal maintenance providing significant cost savings over time.

Noise

One potential drawback of standing seam metal roofs, despite their numerous benefits, is the noise they can produce during rainstorms. However, the noise difference between metal roofs and shingle roofs is generally undetectable to most humans as they cannot distinguish between sounds less than eight decibels apart.

There are also solutions to mitigate this issue. For instance, installing metal panels over existing shingles can help reduce noise levels, as the shingles provide additional insulation. Additionally, noise during rainstorms on steel roofs can be mitigated with the use of proper insulation and solid decking. Even copper roofs, which don’t buffer noise as well as other materials, can benefit from modern underlayments used during installation to aid in noise reduction. Some solutions to consider include:

  • Installing metal panels over existing shingles

  • Using proper insulation and solid decking for steel roofs

  • Using modern underlayments during installation for copper roofs

These solutions can help reduce noise levels and create a quieter environment.
