When it comes to metal roofing systems, you generally have two options: standing seams and seamless metal panels. While standing seam roofs have been a popular option for years, they have drawbacks that many homeowners may not be aware of. Please read our blog to learn about the issues commonly associated with a standing seam metal roof and why a seamless metal roof is often the way to go.
What Is a Standing Seam Metal Roof?
A standing seam roof is a type of metal roofing system where the seams (or joints) between the metal panels are raised above the level of the roof’s surface. These seams “stand” up, which helps to interlock the panels securely and prevent water infiltration. The panels typically run vertically from the ridge to the eaves, which is their primary appeal for many. It does give it a modern, sleek look, but a good roof should have more than cosmetic allure. While standing seam roofs can be quite durable, they are prone to certain issues, especially in areas with severe weather and temperature fluctuation. More on that below.
Why Do People Choose A Standing Seam Metal Roof?
Again, many homeowners opt for a standing seam metal roof due to its sleek, modern appearance and reputation for being more durable than traditional asphalt shingles. And yes, a standing seam metal roof is infinitely more durable than asphalt, but it lacks the other advantages associated with horizontal versus vertical roofing.
What Are the Drawbacks of a Standing Seam Metal Roof?
Oil Canning
One of the most significant issues with standing seam metal roofs is oil canning (a visible waviness or distortion in the flat areas of metal panels.) This aesthetic flaw can occur for a variety of reasons:
Material Expansion and Contraction: Metal naturally expands and contracts with temperature changes. This movement can cause the panels to bow or ripple if there isn’t enough room for expansion or if the panels were installed too tightly.
Improper Installation: If the metal panels are not installed properly (e.g., with insufficient space for expansion, uneven fasteners, or incorrect alignment), oil canning can become more pronounced.
Thin or Soft Metal: Thinner metal panels or lower-quality materials are more likely to experience oil canning, as they are less rigid and can be more easily affected by environmental conditions or stresses.
Panel Size: Larger panels are more prone to oil canning because there’s more material that can flex or move between supports.
Oil canning is a cosmetic issue that rarely affects the structural integrity of the roof. That being said, it can significantly detract from your home’s curb appeal and affect its resale value. Plus, with the cost of a metal roof installation, it better look good for a long time!
Oil canning creates an unappealing rippled look on standing seam metal roof systems.
Water, Ice, Debris Can Cause Damage
Due to its vertical panel design, a standing seam roof sheds water, ice, and debris straight down. Think about it: the slippery, metal panels are essentially a slide for snow, ice, and water. This runoff can damage landscaping, dent vehicles, and create dangerous icy patches in winter. Without the right drainage solutions, homeowners might deal with costly repairs.
Less Customizability
A standing seam metal roof comes in standard panel widths and designs, limiting customization. If you want a truly unique look or need a roof tailored to specific architectural needs, a seamless metal roof offers more flexibility in design and finish options.
Seams=Leaks
Even though standing seam roofs are designed to minimize water infiltration, the seams themselves can still be potential points of vulnerability. Over time, if not properly maintained, these seams can loosen or wear down, potentially leading to leaks.
Why Go Seamless
Seamless steel has the durability of a metal roofing system without the hiccups associated with standing seams and vertical paneling:
Horizontal Design
Seamless roofing is horizontal, which guides water more easily and gradually toward the gutters and downspouts. No sudden rushes of water or the risk of a mini avalanche.
Highly Customizable
Seamless steel roofing is highly customizable and available in a wide variety of colors and finishes. For example, you can choose seamless panels that mimic slate and shake shingles. You won’t find that option with vertical standing seam metal panels.
No Oil Canning
Seamless metal roofs are resistant to oil canning. Their design inherently protects them from the shrinking and expanding experienced by standing seam roofs.
- No Seams or Joints:
- Seamless metal roofs are made from large, continuous sheets of metal, which eliminates the seams that are present in standing seam systems. Oil canning typically occurs at the seams where metal panels are fastened together, causing distortions due to the internal stresses of the metal. With seamless roofs, there are no seams to cause these kinds of distortions.
- Larger Panels and Uniform Surface:
- Since seamless metal roofs use larger, uninterrupted panels, they tend to have a more rigid and uniform surface. This reduces the chances of the metal panels flexing or bending in small areas, which can lead to the visual ripples or waves associated with oil canning.
- Less Stress from Fastening:
- In standing seam systems, the metal panels are fastened at multiple points along the seams. If these fasteners are not installed properly or are spaced too tightly, it can cause the panels to flex between the fastener points, contributing to oil canning. In contrast, seamless roofs are less susceptible to this issue, as there are fewer fastening points and no gaps or joints where stress can build up.
Exceptional Durability (And Virtually Maintenance Free)
With proper care, seamless steel roofs can last 50 years or longer. “Proper care” is generally far easier than with an asphalt roof. Simply ensure your gutters are free of clutter and keep tree branches trim, and you can enjoy your roof for decades. Cleaning involves no more than a hose down with soap and water. And, once again, that water will be directed horizontally into your downspouts as opposed to sloshing into your garden or onto your car.
