Corrugated metal roofing systems can add value to commercial buildings on many levels, from reliable weather protection and proven longevity to energy code compliance, carbon emission reduction, operational savings, higher property values, and enhanced occupant comfort.
Here are more benefits of corrugated metal roofing:
Leak-proof
Unlike roofing shingles which often expose buildings to leaks, corrugated roofing keeps the rest of the building dry. Proper installation is required to guarantee this. The appropriate coatings including epoxy and ceramic coatings also enhance their waterproof properties.
Durability
Corrugated metal roofs last longer thanks to the ridges and grooves that make up for their lightweight nature. The fact that they are not susceptible to corrosion and wearing guarantees their durability. Their noncombustible properties, on the other hand, ensures that they can withstand fire. They do not cave under extreme weather conditions.
Easier installation
You won&#;t need to use up a lot of material for structural support thanks to the lightweight nature of corrugated metals. The load on installation is also greatly reduced. You can always provide the aesthetic appeal that your clients desire with the right finish. Ideally, any customization plan can be effectively achieved.
Enhanced indoor comfort
Corrugated metal roofs can function as cool roofs helping business owners save on annual cooling costs by repelling, rather than absorbing, heat during summer. A comfortable working environment subsequently enhances employees&#; productivity.
Increased property value
Corrugated metal roofs not only help you save on annual utility bills but they can also help commercial buildings command higher rents and selling prices. Markets are also taking notice that energy efficient buildings carry significant economic advantages.
Reduced environmental impact
With climate change rearing its ugly face, the need for environmentally friendly products cannot be overemphasized. Corrugated roofing materials are recyclable and suitable for any project that is focused on achieving sustainability.
Low Maintenance
Traditional roofing systems require regular maintenance practices to guarantee their durability. For corrugated roofs, you&#;ll only need to re-coat the panels once in a long while to take care of the corroded portions. To maintain water-tightness, you may also need to re-tighten the exposed fasteners.
Superior energy conservation
Although low maintenance and durability help keep long-term costs low, a corrugated metal roof design also helps conserve energy resulting in substantial savings over a commercial building&#;s life.
Choosing the ideal roofing design
Corrugated metal roofs can either be aluminum, stainless steel or copper and are told apart by their appearance and costs. When ranked in terms of quality and value, corrugated aluminum roofing stands out from the rest. Its rust resistance ability and flexibility makes it a popular option for a host of building firms.
Stainless steel roofing panels are easily identifiable thanks to their natural gray finish. Corrugated copper roofing is an expensive alternative even though its installation process is quite simple. The ultimate choice largely depends on your budget and the goals you intend to meet. If you are not keen on looking at the specific differences, then the standard corrugated metal or standard seam panels should have you covered.

Deciding on what type of material you should use for a roof or siding can become stressful when you realize how many options you have. Even when you narrow it down to using metal, there are still choices to make.
There are many different types of metal panel profiles to choose from. One of the most popular metal panels on the market is corrugated.
At Western States Metal Roofing, we&#;ve been manufacturing metal roofing and siding panels for over twenty years. Corrugated metal panels are consistently our most often requested panel.
Customers love the longevity and durability, along with the other benefits of metal. However, every metal panel comes with its downfalls.
In this article, we will go over the pros and the cons of corrugated metal panels so you can decide if corrugated metal panels are right for your project.
The Pros Of Corrugated Metal Panels
- Cost-Effective
- Readily Available
- Oil Canning Is Less Obvious
- Simple Installation (DIY friendly)
Corrugated Metal Panels Are Cost-Effective
One of the biggest advantages of corrugated metal panels is that they cost less than a standing seam metal panel. Depending upon the gauge and paint system, the cost savings will be at least 50%.
Corrugated Metal Panels Are Readily Available
Corrugated metal panels are arguably the most common type of metal panel. You should not have a problem finding corrugated panels in your desired quantity or color.
They&#;re sold at almost any home improvement store, although you will find a much greater panel and color selection when going through a metal manufacturer.
Oil Canning Is Easily Disguised On Corrugated Metal Panels
Oil canning, sometimes also known as stress wrinkling, is a cosmetic deformation, observed as waves or wrinkles, in the flat areas of metal roofing and metal siding panels. It&#;s an inherent characteristic of metal that can be caused by multiple factors such as an uneven substrate or from the expansion and contraction of metal.
While the problem is solely cosmetic and does not affect the functionality of a metal roof, it&#;s presence is still unwanted and hard to avoid.
Luckily, oil canning is much more difficult to detect on corrugated metal panels compared to a flat panel like standing seam. The waves and ridges in corrugated panels help disguise oil canning so that if it is there, it&#;s not as noticeable.

Simple Installation
Installing a corrugated metal roof is an easier and faster installation than a metal panel with a concealed fastening system because it requires fewer steps.
Since the installation requires a simpler skill set, more contractors are qualified to install corrugated metal panels. Having more contractor options coupled with less labor time means that these systems are generally less expensive to install.
The easier installation makes corrugated metal panels a great opportunity for a DIY (do it yourself) project. You will save even more money this way by doing the labor yourself.

Fewer Accessories Are Required To Install Corrugated Metal Panels
Corrugated metal roofing will also save you money because fewer accessories need to be purchased for the installation. Corrugated metal panels are easily installed, just by using fasteners.
There&#;s no need to buy any clips like you would for other metal roofing systems. You also need less trim and flashing for a corrugated metal roof than you would for a standing seam roof. Standing seam trim requires purchasing multiple pieces of trim for each roofing condition.
For example, a ridge cap for a corrugated metal roof is a one-piece system. That same ridge cap for standing seam is a three-piece system. Not having to purchase the additional trim and fasteners will substantially increase the overall cost of the roof.
The Cons Of Corrugated Metal Panels
- Exposed Fastener Panel
- Frequent Inspections
- More Material Needs To Be Purchased (Panel Sidelap)
- Panel Appearance
Corrugated Metal Panels Have Exposed Fasteners
The main problem with exposed fasteners is every time they penetrate the panel it creates a potential leak point. Corrugated panels can require thousands of fasteners to keep the roof in place. If the fasteners are not properly installed or become loose, the roof can be vulnerable to leaks. If you are trying to decide upon the best panel for your roof it will come down to standing seam versus some kind of exposed fastener panel. It's important to understand the advantages and disadvantages of each system.

Corrugated Panels Need To Be Inspected Often
While all metal roofing or siding should be inspected annually to prevent any problems from developing further, corrugated metal panels generally require more frequent inspections and maintenance.
The reason you need more frequent inspections for corrugated panels is so you can check the fasteners. Since the fasteners are exposed on corrugated panels, they may need to be tightened. They could possibly even need to be replaced if they are damaged to avoid leaks. The natural expansion and contraction of metal can cause the fasteners to become loose.
Homeowners should perform an inspection after any severe weather that you think may have caused damage. Checking on a roof right after a substantial storm, instead of waiting for your next routine maintenance, might save you from a larger problem.
Foam closures should also be checked during inspections to make sure they are still in good condition. Roofs and gutters should also be checked for leaf buildup, and leaf guards should be installed if you&#;re in an area with a large volume of leaves.
During inspections, also check the corrugated roof for cracked sealant. Sealant is a top reason for roof leaks as it has a short life span and usually isn&#;t replaced on time. The life expectancy of sealant should be listed on its container and replaced as suggested by the manufacturer.
Corrugated Metal Panels Are Not Compatible With Flat Roofs
With a flat roof, rainwater tends to stay on the roof longer as it doesn&#;t have a steep pitch to help with runoff. This is not a good combination with the exposed fasteners as they are more susceptible to leaking. The longer water stays on a roof, the more likely a leak is to occur, potentially resulting in expensive roof repairs.
Panel Sidelap And Corrugated Panels
Corrugated panels will incur a loss of square footage during installation due to the panel side lap, or the overlapping of two like panels.
The panels need to overlap two corrugations for roofing and one corrugation for siding. While this seems minor, it can add up depending on the size of the project.
For roofing, you will have to purchase 10% to 12% additional material for corrugated. For siding, you will need about 6% additional material. Purchasing additional material adds to the overall total cost of the project.
Panel Appearance
The desired aesthetic of your project is subjective and based on personal preference. While the appearance of corrugated panels might not be a problem for every situation, there are certain projects that you might want to go with an alternative panel.
Corrugated panels have exposed fasteners, which is usually regarded as not being as modern or clean looking like a panel with concealed fasteners (such as standing seam).
Corrugated panels are generally used in industrial or agricultural structures. For a residential project where aesthetics are a top concern, corrugated panels are not usually the top choice.
