If a metal roof has been on your radar you have likely been considering 2 different types; standing seam and exposed fastener. Albeit, both of these metal roofing systems are great options, they do have important differences.
R.I.G. Roofing wants to walk you through the advantages, and disadvantages of both standing seam and exposed fastener metal roofing. We also want to help you decide which type of roofing is best for you.
Standing Seam and Exposed Fastener Metal Roofing Pros & Cons
Exposed Fastener Metal Roofing
Metal roofing panels are fastened directly into the structure below. The panel edges overlap and a fastener goes through both layers. That fastener is not covered, thus its given name—exposed fastener. It is usually the most economical choice when it comes to metal roofing systems. Consequently, exposed fastener metal roofing is used on a wide variety of buildings from industrial to commercial and residential applications.
Pros of Exposed Fastener Metal Roofing
- Price. Exposed Fastener systems are less expensive when compared to standing seam metal roofing systems. Exposed fastener systems are cheaper because it takes fewer materials to install them and less labor time.
- Ease of Installation. These systems do not require seaming the panels together. Instead they the panels overlap, making installation much easier.
- Resistant to the Elements. Exposed fastener systems are resilient and long-lasting when installed properly. That being said, make sure any exposed fastener roof is approved by the manufacturer for your location and building type. Also be sure to use a certified roofing contractor, such as R.I.G. Roofing, who have experience installing this type of roofing system.
- Aesthetics. It has a unique appearance. Often thought of as a “traditional” metal roof, seen on agricultural or industrial buildings. Barns, silos, warehouses, agricultural structures, or city buildings can all have exposed fastener metal roofing systems.
Cons of Exposed Fastener Metal Roofing
- No Waterproofing. Installing an exposed fastener roof requires creating many holes that are only covered by the fastener they are attached with. Over time, the metal will expand and contract causing the holes to change in size. Ultimately it can lead to leaking and water damage.
- Fastener Issues. Climate and sun exposure in the Florida elements can cause several problems with exposed fasteners such as withdrawal and UV degradation.
- High-Maintenance. Debris, dirt, sticks, leaves, mildew, and flaking must be regularly checked for and cleaned off of an exposed fastener roof.
- Aesthetics. It may not be considered a good choice for property owners that want a sleek and modern look. Exposed fastener roofing is considered to have a rural look.
Standing Seam Metal Roofing
Standing seam metal roofing has a smooth, sleek appearance. Metal panels are placed on top of raised seams and conceal the fasteners below. It is considered a high-end roofing system, commonly used on architectural or commercial buildings.
Pros of Standing Seam Metal Roofing
- Hidden Fasteners. Concealed fasteners have a longer lifespan. They are protected from environmental factors and UV exposure.
- Thermal Movement. Standing seam metal roofing is designed to deal with expansion and contraction. Hence, it is less prone to leaks than its exposed fastener counterpart.
- Lifespan. Metal roofing with hidden fasteners are prone to significantly longer lifespans. They also require less maintenance.
- Aesthetics. A standing seam roof offers a clean, and sleek appearance.
- Choice. These roofing systems can be constructed with a variety of metals. Therefore, they are used in simple, as well as complex designs, and offer more architectural freedom.
- Energy Efficient. Standing seam systems are made with roof cooling coils, highly reflective colors, and emissive metals. All of that creates a hyper-energy-efficient roofing system.
Cons of Standing Seam Metal Roofing
- Price. Standing seam metal roofing is more expensive when compared to other metal roofing. However, value in the long-run is also important.
- Labor Intensive. Installing a standing seam roof is distinctly more complex and labor-intensive. It is imperative to find a contractor with experience installing standing seam roofing systems, like the professionals at R.I.G. Roofing.
- Limits. A standing seam roof cannot be used for flat roofing structures.
- Replacement and Repairs. It becomes harder to replace or repair this type of roofing system because of its complex nature, sealing and adhesion.
