Standing Seam (Concealed Fastener) Metal Roofing Systems

Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad, flat area between the two legs. It’s also described as having raised seams, or vertical legs, that rise above the level of the panel’s flat area. Standing seam systems have fasteners that are hidden, whether the panel is attached to the roof deck using a clip or is directly fastened to the deck under the vertical leg utilizing a fastener flange. Standing seam is considered a higher quality system.

Advantages of Standing Seam Metal Roofing:

No Exposed Fasteners – One of the most significant benefits of standing seam metal roofing is that no fasteners are visible on the surface, which means they aren’t exposed to UV, moisture, wind, and other elements that can cause a fastener to wear out over time. Also, standing seam systems don’t put holes in the panels that are protecting your structure. Plus, some people see fastener heads as unsightly, which is why using a standing seam system to hide them is common. (Note: There are flashing materials and details that require rivets and exposed fasteners to function correctly.)

Allows For Thermal Movement – When you restrict the expansion and contraction needed for proper thermal movement of a metal panel, you can run into problems, such as oil canning, fastener withdrawal, increased noise, and more. In standing seam roofing systems, the panels generally aren’t double pinned (if installed to our recommended details), meaning they can expand and contract better. This is especially true if slider/expansion clips are installed or if it’s a snap-lock system where the metal can move freely with a clip.

Longevity & Lifecycle – Metal roofing lasts significantly longer and requires less maintenance, especially when compared to other roofing types, such as asphalt shingles or concrete tiles. Since fasteners don’t penetrate the surface of the metal on a standing seam system, regular maintenance to check for withdrawing, loose, or damaged fasteners is even less frequent. However, maintenance on a standing seam roof is still essential and often must need to be performed by a professional contractor.

Higher quality paint systems - One of the main benefits of PVDF paint systems is that they hold on to their color longer than most other coil coating options. Many home and property owners specifically choose to install a metal roofing system because they know it will last decades without too many signs of degradation — including the appearance. Carbon-fluorine bonds, like those present in a PVDF resin, are some of the strongest bonds, which makes them “virtually immune to degradation from sunlight, moisture, acids, pollutants, and chemicals.” (Glass Canada) These PVDF resins, in turn, protect the pigments that form the color in the paint system, which is why PVDF metal roofs and walls hold on to their color longer than SMPs and most other paint options. Standing seam metal roof systems typically offer a PVDF paint system, which will increase the lifespan of the appearance of your roof.

Disadvantages of Standing Seam Metal Roofing:

Higher Cost – One of the most significant drawbacks to standing seam metal roofing is the fact that it can be more expensive when compared to other metal roofing types, especially exposed fastener systems. However, it’s not always the highest price, as metal shingles and other stamped metal materials tend to come in at a higher price, even though stamped materials are often made from 26 gauge or thinner substrates.

Exposed Fastener Metal Roofing Systems

Exposed fastener metal roofing is defined as a roofing system where the panels are fastened to the structure through the face of the metal and directly into the roof deck or framing below. The panel edges lap one another, and the fastener goes through both layers of metal. It’s called “exposed fastener” because the head of the fastener is visible and not hidden by a seam. An exposed fastener system is typically considered the economical choice of metal roofing and is classically used on residential, structural, industrial, and agricultural buildings.

Advantages of Exposed Fastener Metal Roofing:

Less expensive – One of the most significant benefits of choosing exposed fastener metal roofing is that it’s less expensive, especially when compared to standing seam systems.

More Contractors Have Skills & Tools to Install It – Many contractors promote that they know how to install metal, but keep in mind that installing standing seam and installing exposed fastener panels require a much different skill set. Since exposed fastener metal roofing is easier to install, most contractors who install roofing have the necessary knowledge, experience, and tools needed to offer exposed fastener systems to their customers. Installing all metal roofing requires skill as far as lining up the panels, correctly spacing the fasteners, and cutting the panels to match the roof’s geometry, it doesn’t require the same level of craftsmanship as a standing seam metal roofing does.

Better Suited for DIY (Do-It-Yourself) Projects – Since it is easier to install, there’s more of an opportunity for home or building owners to perform the installation themselves as a DIY project. For standing seam metal roofing, we always recommend hiring a knowledgeable, experienced, and trusted installer.

Can Be Purchased at Big Box Stores – Exposed fastener profiles, such as PBR panels, R-panels, or 5V crimp panels, can be purchased from many different places, including directly from the manufacturer, from a regional panel supplier, lumber yards, and even big-box stores like Home Depot or Lowe’s. This can provide more versatility for pricing, options, colors, sizes, and more.

Disadvantages of Exposed Fastener Metal Roofing:

Many Roof Penetrations – If someone came up to you and told you that they were going to drill a hole in your roof, you would be concerned, right? Exposed fastener metal roofing actually requires installers to make many holes (for fasteners and screws) in the metal that is protecting your structure, which opens the roof up to numerous problems. Most notably: Water penetration and leaking. In fact, springing a leak is one of the most common problems with exposed fastener roofs, primarily because water can do a lot of damage in a short amount of time. Also, because leaking is a concern, always be cautious of how low of a slope and what type of underlayment you use on your roof for exposed fastener metal roofing systems.

Fastener Problems – Exposed fastener systems put the integrity of your roofing structure in the hands of the fastener and the gasket, which is the thin piece of material between the head of the fastener and the metal panel. This can lead to many issues, such as:

• Fastener withdrawal – The expanding and contracting of the metal roof over time is inevitable. Directly fastening the metal down to the structure without a clip limits the amount a roof can expand and contract during temperature fluctuations, which can cause the fasteners to back out as the metal moves. If the gasket is no longer touching the surface of the metal, there is the potential for water to get into one of the penetration points.
• UV degradation – Another fastener issue is that the gasket is subject to quicker UV degradation than the metal fastener itself. The amount of time that it takes a gasket to degrade from sun exposure varies depending on what material the gasket is made of, such as neoprene, silicone, rubber, or otherwise. This degradation of a fastener’s gasket is the reason why maintenance on an exposed fastener metal roof is vitally important.
• Incorrect fastener installation – When you have many penetration points and fasteners, there is more of an opportunity for improper installation of a fastener, which is another way for water and air to leak into a structure.

Lower quality paint systems - The main disadvantage of an SMP paint system is that it will likely chalk and fade more than a PVDF system, especially if exposed to significant sunlight/UV rays. The color pigments in SMP systems break down in less time because the chemical bonds in the silicone-modified polyester resin are not as strong as a polyvinylidene fluoride formula, leading to the color’s fading. The same goes for chalking; as the SMP resin breaks down and loses adhesion to the surface, the particles will turn white, and the chalking will become more apparent.Polyesters and silicone-modified polyester (SMP) paint systems are popular choices for exposed fastener because they’re less expensive than the polyvinylidene fluoride (PVDF) paints typically used on standing seam systems.

More Frequent Maintenance Required – When compared to a standing seam metal roof, exposed fastener roofs require more frequent maintenance, especially regarding fastener upkeep.
