Metal Roofs: Standing Seam vs. Screw Down

Understanding the Two Types of Metal Roof Systems

Metal roofing has become a popular choice for both residential and commercial buildings due to its durability, energy efficiency, and sleek appearance. However, not all metal roofs are the same. The two primary types of metal roof systems are standing seam metal roofs and screw down metal roofs (also known as exposed fastener metal roofs). Each type has its unique characteristics, benefits, and drawbacks. Understanding these differences can help you make an informed decision about which metal roofing system is best for your needs.

Standing Seam Metal Roof

A standing seam metal roof consists of panels that are fastened together using concealed clips or fasteners. These panels run vertically from the roof’s ridge down to the eaves and interlock along the seams. The fasteners are hidden beneath the panels, providing a sleek, modern appearance while also protecting the fastening system from the elements.

Benefits of Standing Seam Metal Roofs

1. Longevity – With proper installation and maintenance, a standing seam metal roof can last 50 years or more.
2. Weather Resistance – The concealed fasteners help prevent leaks and corrosion, making it ideal for harsh climates.
3. Expansion and Contraction – The panels are designed to expand and contract with temperature changes, reducing the risk of warping.
4. Low Maintenance – Since there are no exposed screws, there is less risk of fastener failure and water penetration.
5. Modern Aesthetic – Provides a sleek, high-end look that enhances curb appeal.
6. Better Warranty Options – Due to its superior durability, many manufacturers offer extensive warranties on standing seam metal roofs.

Screw Down Metal Roof

A screw down metal roof, also known as an exposed fastener metal roof, consists of metal panels that are fastened directly to the roof deck using screws with rubber washers. These fasteners penetrate the metal and remain exposed, making this system more straightforward and cost-effective to install.

Benefits of Screw Down Metal Roofs

1. Lower Upfront Cost – Generally, screw down metal roofs are more affordable than standing seam systems.
2. Simpler Installation – The straightforward fastening system makes installation faster and less labor-intensive.
3. Durability for Certain Applications – When installed in low-impact areas such as sheds, barns, and warehouses, screw down metal roofing can last 20-30 years with proper maintenance.
4. Classic Appearance – Provides a traditional metal roof look that works well for agricultural and industrial buildings.

Which Type of Metal Roof Has the Potential for Oil Canning?

Oil canning is a visible waviness or distortion that can appear on metal roofing panels due to stress or improper installation. Standing seam metal roofs have a higher potential for oil canning because they use flat panels with concealed fasteners. While oil canning does not impact the roof’s performance, it can be an aesthetic concern. Proper installation techniques and choosing thicker gauge metal can help reduce the risk.

Screw down metal roofs, on the other hand, are less prone to oil canning since their design typically includes corrugated or ribbed panels, which add structural integrity and minimize surface distortion.

Which Type of Metal Roof Lasts Longer?

When it comes to longevity, standing seam metal roofs outperform screw down metal roofs. Because the fasteners are concealed and allow for thermal expansion and contraction, standing seam systems can last 50 years or more.

Screw down metal roofs, however, typically last 20-30 years, primarily because the exposed fasteners and rubber washers degrade over time, leading to potential leaks and necessary replacements.

Which Type of Metal Roof Has Better Warranties?

Manufacturers offer better warranties for standing seam metal roofs because of their durability and weather resistance. Homeowners and business owners can expect warranties ranging from 30 to 50 years, depending on the manufacturer and material quality.

Screw down metal roofs usually have shorter warranties, often between 10 to 20 years, due to the risk of fastener-related issues over time.

Which Type of Metal Roof Requires Less Maintenance?

Standing seam metal roofs require significantly less maintenance than screw down metal roofs. Because the fasteners are concealed and the panels can expand and contract naturally, there is minimal need for ongoing upkeep.

Screw down metal roofs require regular maintenance, including checking for loose or deteriorating screws, replacing rubber washers, and sealing potential leaks. Failure to maintain these components can lead to premature failure.

Which Type of Metal Roof is Best for Residential Roofing?

For residential applications, standing seam metal roofs are the better choice due to their longevity, minimal maintenance, and superior weather resistance. They also provide a modern, high-end aesthetic that enhances property value. Additionally, their concealed fasteners eliminate concerns about leaks and deterioration over time.

Screw down metal roofs are more suitable for non-residential applications such as barns, storage units, and industrial buildings, where cost-effectiveness is a higher priority than long-term performance.

Is a Metal Roof Right for You?

Before choosing a metal roof, consider the following factors:

Pros of Metal Roofing

• Durability – Both types of metal roofs last longer than traditional asphalt shingles.
• Energy Efficiency – Reflects heat, reducing cooling costs.
• Fire Resistance – Metal is non-combustible and offers excellent fire protection.
• Eco-Friendly – Made from recyclable materials and offers a sustainable roofing option.

Cons of Metal Roofing

• Higher Initial Cost – Standing seam metal roofs require a larger investment upfront.
• Noise Factor – Rain and hail can be noisier compared to other roofing materials.
• Potential for Denting – Some metal roofs can dent from severe hail or fallen branches.
