Types of Standing Seam Metal Roofing Systems

September 13, 2021 by Infinite Roofing Leave a Comment

Standing seam meatal roofs are commonly used for commercial, industrial and becoming more popular residential roofs. This type of roofing system is a very versatile option offering advantages like durability, long lifespan, cost efficiency, and a variety of design options. Most commonly a metal roof has previously been installed on commercial buildings but because of the most recent design options, it is increasing its popularity with homeowners.

A standing seam metal roof is typically installed in a vertical line pattern running from the eave to the ridge. They feature a raised interlocking system which connects adjoining panels. This ensure that the fasteners are hidden for a sleeker look, because the fasteners are not visible most people prefer a standing seam system. Another reason a standing seam roof is desirable beyond its approved appearance, the panels require much less maintenance and a longer lifespan. Metal roofing system with exposed fasteners on their panels allow water to penetrate causing damage over time. These roofs require yearly maintenance which ends up costing more than a stand seam roof.

Type of Standing Seam Metal Roofs

How each panel is physically attached is call the attachment method, the panel attach to the roofing deck, purlins and rafters. There are two different styles of attachment: clipped and fastening flange.

Clipped: The clipped system attaches to the substructure with a heavy gauge steel clip that is designed to integrate with a male and female panel. A clipped system is typically installed over a solid deck or an open frame like on a pre-engineered metal building. These clips offer a more significant space for expansion and contraction. Because of this commercial and industrial applications with long panel runs are a better suited match. Weather tightness warranties are common with clipped panel systems based on panel design and installation.

Fastening Flange: These panels are attached directly to the roof by the fastener through the slotted flange. The following panel then snaps into the top and covers both panels with the fastening flange and a screw. This type of panel is the most affordable standing seam system but there are some limitations. This system is not suited for projects that require a weathertightness warranty and require a roof deck to be present. The slotted flange has limits on expansion and contraction unlike the clipped attachment method. Fastening flange panels are best suited for residential projects and smaller commercial buildings.

Clipped: Different than fastening flange, clipped panels attach to the substructure using a heavy steel clip with male and female legs. The clipped standing seam system are installed over a solid deck or an open frame. Some buildings that have open frames include pre-engineered metal commercial buildings and industrial buildings. The clipped system allows for contraction and expansion unlike the fastening flange system. As a result the clipped panels are best suited for long panel roofs commonly found on commercial, industrial and educational buildings. This panel design has installation requirements where weathertightness warranties are applied.

Engagement Methods

Mechanically Seamed: In this method a seaming machine is required to mechanically press the panels together for the metal roof installation. This process involves two folds pressing the panel legs together and this bond form as very strong connection. This method is most commonly used on slow slope roofs that have a high wind uplift and where weather-tightness is required. There are two types of seaming machines, single pass and bi- directional. A single pass machine can complete roughly 10 feet per minute and as you can imagine a bi-direction pass can complete about 50 feet per minute. A bi-directional seaming machine can go along the metal panels in both directions, while a single pass will only run from eave to ridge.

Snapped: In this engagement method snapped panels make use of their male/female legs and are simply snapped in place. When pressure is applied their vertical legs being positioned over one another become engaged because of the design and snap together. This can be done my just using a gloved hand or a rubber mallet can be used.

For a standing seam metal roofing system there are two different types of metal panels, symmetrical and asymmetrical. Symmetrical panels are the exact same on both sides and in comparison, the legs on asymmetrical are different. Symmetrical standing seam panels are the most popular because of their initial and long term savings. They are more economically friendly in terms of labor and the reduced chance of damage from leaking.

Asymmetrical panels need to be installed from one end of the building all the way to the other in a sequence. Compared to symmetrical panels that can be started from anywhere on the roof, making it easier to skip sections also. Asymmetrical panels are less convenient and flexible. Symmetrical panels end up have much less scrap or waste and reduced costs when being compared to asymmetrical panels. This is because symmetrical standing seam panels do not have male/female connections. These seams mirror image each other and a seam cap covers them to allow for easy removal if a replacement is needed for individual panels.

In order to replace single panel of symmetrical standing seam roofs an un-seaming machine must be used. This machine will open the cap back to the original shape leaving the panel undamaged. Once removed the panel can easily be replaced and reinstalled. With all the benefits of symmetrical seam panels you might expect them to be more expensive because they offer an easier installation, but you should always factor in building design, codes, and future building modifications.

Which Type of Metal Roof is Best?

Galvalume roofing material combines three metal, steel, aluminum and zin, and is then coated in silicone to protect it from the elements. This is the least expensive type of metal roofing and come in a large variety of colors. Galvalume is corrosion resistant, recyclable and can be installed over any roof.

Aluminum is a popular choice because it performers well in in sea and saltwater environments, and also is the most sustainable material in the world. It does the best in harsh weather conditions and is one of the most predominant metals used worldwide. Aluminum is light weight and does not rust or corrode, it has a medium price point and is readily available.

Copper is another choice for metal roofing but comes at the highest price point. It is a beautiful color and very durable, also one of the lightest weight metals but is about $1,000 per square.

Looking for a roof that would last years and also be Eco-Friendly?

Infinite Roofing and Construction

Shingles have to be replaced by the homeowners at some point in a roofs lifetime. Conventional asphalt shingle roofs last about 20 years if you are lucky because they are constantly exposed to sunlight, heat, cold, rain, wind, and sometimes snow, sleet, and hail.

If you’d like a roof that will outlast a conventional asphalt shingle roof and is made from eco-friendly roofing materials, consider the products outlined here. Many of them are virtually immune to hail. Green roofing products are many and varied, ranging from recycled-plastic shingles to recycled-metal roofs to sustainably harvested or reclaimed wood roofs to having plants grow on your roof. The best option for your home depends on the design of your home, local building codes, and price considerations.


Recycled Shingles

The most popular and perhaps the most environmentally friendly option would be shingles made from recycled waste materials, such as plastic, rubber, or wood fiber. Some products are made from clean post-consumer waste (waste from homes), others from post-industrial waste (factory waste). Recycled-content shingles are amazingly durable, and they look amazing, too. You’d never be able to guess they were made from “waste” materials!

Waste from landfills are reduced by recycled-content roof shingles help our need to extract and process raw materials, which reduced pollution and lowers energy consumption. Some of these products are recyclable, too, and many come with amazing 50-year warranties. A few even carry fire ratings that could lower your insurance rates.

A popular choice throughout the country has been wood shingles and shakes for homeowners and roofing contractors. Unfortunately, conventional wood shingles are made from old-growth western cedar. Although the amount of energy it takes to produce this product is relatively low, the harvest of old-growth trees is not sustainable in the long run. These shingles are also quite combustible and can no longer be used in areas where there is a risk of brush and forest fires.

If you are still considering installing wood shingles try considering shingle made from reclaimed lumber. Reclaimed lumber products are made from old bridges, mills, old water, and wine tank and other sources.


Slate and Clay Tiles

Slate produces an extremely durable tile, one that can last hundreds of years, and is also an all natural material. It is, however, an energy-intensive process to mine the slate tiles, but most companies salvage slate and clay tiles. Roofing contractors are very familiar with slate roofing as that is getting increasingly popular, the install cost may be a little pricey, but with that being said your roof will last twice as long with barely and repairs to be done.

Metal Roofing

Many metal roofing products include at least some recycled material, but one advantage of metal roofing is that it can be recycled at the end of its life. Because metal roofs can last up to 50 years, roof replacement is less frequent, which means less waste in the long run. They offer exceptional durability and fire-resistance, and they’re ideal for those who want to collect rainwater from their roofs to water gardens (or for household uses). You don’t have to worry about chemicals that might leach from a conventional asphalt roof. Standing-seam metal roofs work nicely as the base for thin-film photovoltaic panels, too.

Metal roofs are great in snowy climates because they allow snow to slide off, which prevents ice dams from forming. (Ice dams can damage roofs of improperly insulated homes.) To protect walkways from snow sliding off the roof, you’ll need to install snow bars or a similar device over walkways, garage doors, and entryways. Although other eco-friendly roofing options may not always be available at every local roofing company or roofing contractors may not be trained to handle the installation of those specific roofs, metal roofing on the other hand is extremely popular and the popularity is growing so most if not all roofing contractors know the inside outs of installing a metal roof.




Rubber Roofing

Another recycled roof material is reinforced rubber shingles made from old steel-belted radial tires. The material is coated with ground slate for texture and comes in a variety of colors. A big advantage to this material is a long life and a 50-year warranty, including against hail and other extreme weather. The only downside to rubber roofing is that it is not always allowed in all counties. Make sure with your local roofing company and the building department that rubber roofing is allowed to be installed on your house.

Green Roofing

A green roof is a roofing system that is an addition to the existing roof and add flora to it. Depending on the green roof type that you plan on installing the plants may be modular or have a drainage system to it.

There are many different reasons as to why a homeowner of a business owner would want to get a green roof. The installation of a green roof reduces the need to manage any stormwater that accumulates, as well as the stress put on local sewer systems. The plants would also help prevent the distribution of smog and would catch any pollutants in the air.

Having an eco-friendly roof not only helps the environment but also as a homeowner, your roof life will last longer preventing the replacement costs. Contact your local roofing contractor today to discuss the options of eco- friendly roofing and how that may benefit you.
