The Importance of Cleaning Metal Roof and Wall Panels
Metal panels need attention; they should not be taken for granted. True, they are a notably long-lasting and attractive choice, particularly with the myriad colors and protective finishes available, but once installed, proper care is imperative in order to maintain their durability, performance and good looks for decades.
What are the main culprits of potential damage? Dirt and residue (such as from trees or animals) left to sit on metal panels, for instance, can cause the irreversible degradation of protective coatings, thereby compromising the longevity of roof and/or wall systems. Additionally, corrosive elements, including bacteria, mold, mildew or even acid rain can damage the structural integrity of the panels. Additionally, buildup of foreign elements, such as leaves, can hide potential leak areas or places that may be rotting away. Even in terms of energy efficiency, keeping the panels clean may help a roof reflect heat as they were originally intended.
To keep panel appearance in top shape, protecting the finishes must be a priority—otherwise, you may find yourself needing to re-coat the panels. Stains from leaves and moisture, algae and lime deposits that remain on panels for extended periods can do serious harm to the finish. It should be noted, however, that re-coating should only be considered if the panels remain structurally sound and if doing so wouldn’t void the manufacturer warranty.
How often should you clean metal panels? Most experts agree that at a minimum, an annual cleaning is advisable in order to keep the panels free of common elements that can jeopardize the integrity of the finishes. If you have heavy tree overhang, you may need to clean it or remove debris a little more frequently.
Deep cleaning to remove more stubborn substances (e.g., tree sap, oxidation) can be done every 3 to 5 years, depending on the building conditions, location and weather, etc. Interim, moderate cleanings can also be performed following substantial weather events and seasonal allergen build-up. It’s a good idea, in fact, to assess roof conditions before winter hits to identify any potential issues that need to be addressed.
No matter the frequency, perhaps the most important advisory when it comes to cleaning the panels is to follow the panel manufacturer’s recommendations regarding who should perform the work and with what solutions and tools so as not to void any warranties. In some instances, it may be beneficial (or perhaps even required) to have a professional building surface cleaning company with metal panel experience do the work.
Tips on Proper Cleaning Techniques and Solutions
As for the maintenance and cleaning instructions, it’s always best to refer to the manufacturer’s guidelines in order to best protect specific products, for example, to determine which cleaning solutions and techniques work best for a given manufacturer’s panels. Neglect or improper care can degrade the finish, compromising not only the visual appearance and performance but, as noted, can also potentially void the panel warranty. But maintaining the panels doesn’t just entail washing them like you would a car; it also means keeping them free of harmful debris.
Here are a few general tips for the proper cleaning of metal panels (again, refer to the panel manufacturer’s specific directions):
Simple cleaning: generally, water and mild detergent will be sufficient. Do NOT use bleach, which can change the finish color or have a harmful interaction with certain finishes.
Water-soluble dirt or other deposits requiring more complete cleaning: you can use a solution of hot or cold water mixed with detergent. In a container of water, use a 5 percent solution of commonly used commercial (non-industrial, non-bleach) mild detergent. Use a cloth or a soft-bristle brush for application of the cleaning solution, followed by a clean water rinse. Alternatively, pressure-washing with a 40° tip is also an option.
Non-water-soluble deposits such as tar, grease, oil and adhesives: a solvent or alcohol-based cleaner may be required. In this case, since most organic solvents are flammable and/or toxic, they must be handled accordingly. Generally, keep them away from open flames, sparks and electrical motors; use adequate ventilation, protective clothing and goggles; and read the manufacturer’s Material Safety Data Sheet (MSDS) of any solvent used for any other specific safety details.
The following are among the cleaners widely recognized by manufacturers for this type of non-water-soluble cleaning: alcohols—denatured alcohol (ethanol) and isopropyl alcohol (rubbing alcohol); and solvents, including VM&P Naphtha, mineral spirits, kerosene, and turpentine (wood or gum spirits).
For any level of cleaning, do NOT use wire brushes, abrasives, or similar tools that will erode the surface coating and leave scratches or other finish damage that can lead to corrosion. Additionally, always test a small area before proceeding with any of the cleaning agents mentioned to ensure there is no adverse effect resulting from the product’s use.
Remember, the misuse or abuse of any of the acceptable cleaning agents will automatically void any manufacturer’s warranty for the affected surfaces, so be sure to check with the manufacturer and also follow directions on any cleaning products used.
By following the tips above, installers can keep metal panels looking great and performing well for years to come.

How to Avoid Common IMP Installation Mistakes
Insulated metal panels (IMPs) are ideal for many roofing and wall applications. They are considered a top-of-the-line choice known for their superior insulation value, high performance air barrier, design flexibility, and fast installation. The simplicity of installation creates a high-performance building envelope. The many design options provide a versatile building solution for commercial, industrial, and institutional projects.
Sounds great, doesn’t it? What’s the catch? Well, those benefits won’t mean much if proper care is not taken during the installation process to ensure you’re getting what you paid for. Potential consequences can span the gamut—from minor aesthetic headaches to extremely costly errors such as leaks and structural issues.
Here are some ways to avoid common pitfalls when installing IMP panels on your next metal wall or roof project.
1. Pay attention to the manufacturer’s product installation manuals.
Installation manuals are not just for show! Even the most experienced installer should read, review and understand the installation guide before installing IMPs, and the panels should always be installed in accordance with the project’s installation drawings.
Don’t simply rely on the “what-you’ve-done-before” mindset. Take the time to review the specifics for every individual project. In addition to providing the information needed to execute a successful install, it can also give installers an opportunity to build upon their own knowledge base. One of the most common errors is related to proper receipt and handling of the panels. Investing a few minutes before the project starts and at the start of each day to review key topics helps avoid costly errors and improves production.
If you have a question or something does not seem right stop and call the manufacturer. It is always best to address a problem up front than try and fix a problem after the building is in operation.
2. Equipment check. Do you have what you need?
To keep your IMP installation on track, it’s imperative to ensure you have the equipment you’ll need for the job. Does your project need one or two forklifts, is a crane a better option? Will your project include longer-length IMPs being installed in a vertical orientation? If so, you may need special lifting equipment so as not to damage the panels. Whatever the details, crews need to be prepared to receive a project’s specific materials on site. A little advance planning will ultimately save you time and money by reducing labor and avoiding costly mistakes.
3. Don’t assume every IMP application is the same.
All buildings are not created equal. Just because a construction crew has had experience installing insulated metal panels on past jobs, doesn’t mean they can assume the process will be exactly the same every time. There will always be specific conditions and variables that need to be taken into consideration. Techniques used for vertical industrial panels will be different for horizontal architectural panels.
The vapor barrier (a key function of an IMP) is a great example of how a miscalculation can be problematic. Depending on the panel, the vapor barrier may be applied either at the factory or at the jobsite. If the project calls for a cold storage environment, the “warm” side of the vapor barrier will be on the exterior. Alternatively, a commercial or industrial application generally calls for the vapor seal to be on the opposite side of the panel. Confuse placement of the seal and you’re bound to run into problems down the road.
4. Be on the lookout for creases, buckles and framing alignment.
A crease or buckle on the face of a panel might seem like no big deal, but that couldn’t be further from the truth. In fact, framing alignment is one of the most critical aspects to ensure a proper fit-up of the construction as a whole. In terms of the panels themselves, not only will a framing misalignment not LOOK right but can also cause numerous efficiency and performance issues. Installing inexpensive shims can avoid panels needing to be replaced.
Additionally, make sure the first panel is plum and square, if you start right it is much easier to finish right.
Purlins must be level and square and all framing and bracing should be installed before installing panels. (The IMP manufacturer should specify the amount of tolerances allowed.) Also, take care with caulking and taping, foam-to-foam connections (in order to mitigate potential vapor leaks), seaming, and lap joints.
Attention to detail will avoid costly mistakes.
5. Always think ahead.
Being proactive may be the most important piece of advice construction crews need to hear.
For one, be sure to have a panel surplus on hand. You may be of the mindset that ordering extra panels is at worst a waste or at best, not worth the effort. This is a common judgement error that often leads to installation delays. If a crew has only ordered the exact number of panels needed for a job and there is any damage to the product, whether prior to delivery, on-site or during the installation, there a risk to the project schedule. Waiting on replacement panels can wreak havoc on schedules, especially with panels that may need special manufacturing due to custom components, finishes or colors. What do you do with extra panels you don’t need on the initial installation? Building owners can hold on to any surplus panels to be used as replacements, as needed, over the lifecycle of the building. A little preparation today can go a long way.
Other best practices include understanding the project’s site conditions and ensuring crews remain crews up to date on proper installation techniques—including staying current with training and certifications.
By taking this advice to heart, you can exponentially increase your ability to enjoy the many benefits of IMPs and be confident in your investment.

Protecting Metal Panels from Rust
One of the many benefits of metal panels that contributes to their strengths is the fact that there are so many rust-resistant coating options with different levels of protection, making them a great option for virtually any environment or any budget. That said, though, missteps during storage, as well as during and after installation, can leave you with unwanted corrosion, i.e. rust. Factors such as improper storage, improper cutting, or other elements the metal might come in contact with can wreak havoc that are beyond the manufacturer’s control.
Regardless of the finish you have—painted, unpainted, high-end coatings or standard coatings—here are some simple installation and care instructions that can help further maintain the longevity of your metal panel product.
Preventing Rust When Materials Are Delivered
Proper material delivery/site storage is the first step to preventing rust. Be certain to check your panels while uncrating after storage on site for any early signs of corrosion, such as black discoloration or white rust/residue on them. This is a sure sign that that panel has been improperly stored and water has not been able to properly evacuate the panel bundles. Do not install any panel on which this has occurred, as the panel finish has most likely been compromised due to improper storage. If you go ahead and install it, that panel is going to continue to corrode and eventually lead to further rust/corrosion.
Make sure that you’re not trapping any sort of moisture in between the metal panels or restricting them from being able to drain when stored on site. Although the panel itself is corrosion-resistant, if you subject it to repeated and significant water being trapped in between the sheets by either not storing the material out of the mud and ground water, or if you’re not sloping the material bundles in such a manner that they can drain, then the result can yield “wet storage stains.” Therefore, if you want to prevent any sort of damage due to improper site storage, you must make sure that the panel is able to drain while stored and, if possible, tarp to resist heavy moisture concentrations such as snow and ice during inclement weather if necessary.
Preventing Rust During Installation
Next, let’s look at some installation no-no’s that WILL most definitely eventually lead to rust—and things to avoid. The first is the accumulation of drill shavings. Whether it’s a roof panel or a wall panel, when you’re installing the screws, even if you’re pre-drilling for the screws, you’re going to generate metal shavings. If those metal shavings are not removed and left to sit or cling to the sheeting those shavings will rust and will stain the roof or wall sheets. The shavings are uncoated/raw metal with no corrosion protection that can and will rust quickly. Eventually, the shavings may wash off or be blown off the roof or wall, but might not be until after they’ve stained the sheeting, thus leaving you with an issue to remedy and, since the “culprit” is gone, questioning if it’s just a stain or something more serious.
Remove the shavings as soon as you can to mitigate this issue. Additionally, if you’re going to do any field cutting, you need to do so via a shearing process utilizing the proper tools, such as electric nibblers, hand snips or electric shears. Any other type of cutting can cause the edge of the base material to become exposed and no longer protected by the Galvalume and painted coatings as they become disrupted. Using tools such as a “hot” saw, abrasive blades or even a reciprocating saw leads to a tearing motion rather than shearing motion, which will strip the metal of that protective coating; over time it can start to rust.
Graphite is another corrosive element that should be avoided as it is not a friend to Galvalume metals. Therefore, stay away from writing on your Galvalume material with pencils because over time the graphite will react, break down that protective layer, and lead to corrosion. If you do write on the panels with a pencil, make sure you clean it off. The best solution is to use permanent markers/Sharpies or dry erase markers.
Watch out for overspray from any adjacent wall coatings or finish systems like Stucco or similar masonry products, which can also damage panels if not removed promptly. And be certain not to rest the base of any metal panel in direct contact with material that is corrosive, such as concrete, or in such a manner that water can become trapped behind the panel and not able to drain. Industry recommendation is to maintain an eighth of an inch to a quarter-inch gap at the base of all your wall panels for not only expansion/contraction but for proper drainage and to prevent contact with dissimilar/corrosive materials.
Preventing Rust After Installation
Although Galvalume—whether bare or painted—is highly corrosive-resistant by nature, it too has its Kryptonite. Post-installation, the most important thing is to make sure you’re not adding something to the roof that’s going to react chemically/negatively with the Galvalume finish/coatings. For instance, many people don’t recognize that if they have mechanical units on a roof, the condensation that comes out of those mechanical units, when deposited directly onto a Galvalume panel over time, will lead to corrosion and rust. This condensate should either be filtered before exited onto the roof panel or drained via piping and not directly onto the sheeting.
Contact with dissimilar metals, whether it be via incorrect type or method attachment from metal signage, solar panels and snow retention can be another major factor in post-installation corrosion. Panels must not come in contact with or be exposed to the runoff from the following metals: copper (lightning arrest systems, flashing, roof jacks, HVAC drainage); lead (roof jacks, pipe flashing); iron (pipes or soil); and, as previously noted, metal shavings.
Post-installation, panels must also not come in contact with or be exposed to the runoff from chemicals, such as acid from batteries and acid washing brick, and even pressure-treated lumber.
What To Do In Case of Rust
Let’s face it. Sometimes, despite all your efforts…someone didn’t get the memo and rust happens. Now what do you do? How can you safely can attempt to repair it or remove it without causing more damage?
First off, here’s what NOT to do. Heavy solvents that are meant to remove paint or stains can/will adversely affect the metal. If you witness a rust stain on the roof, don’t go up there with paint remover, acetone or any other toxic solvents and start scrubbing on it because you most likely could make matters worse. You might remove the stain along with the finish entirely, leading to bigger problems. (If you’re an end user, check your finish warranty and manufacturer maintenance documentation supplied to you by your builder/installer for guidance on cleaning and repairs.)
The key is to identify if the rust is just a stain /discoloration or it’s more systemic. Is the catalyst (ex.: a shaving) causing the rust still present? If it’s just a surface stain and the coating hasn’t been damaged, it might just be a matter of getting some mild detergents or something else to remedy the situation. Some good options are Formula 409 or Simple Green and Soft Scrub without bleach or something similar. and it may require a trial and error process to determine which is most effective based on the condition you’re trying to remedy. Products such as Rid O’ Rust or similar whose key ingredient is oxalic acid can be used diluted with water. With any of these products, test a small area first and wait to see results before proceeding to larger areas. And always be certain to fully rinse/flush areas of cleaning products to ensure no residues /films remain.
Always start light. Don’t break out any steel wool and/or metal grinders and start trying to get the rust off the panel that way. If it looks to be more than just a stain—perhaps you clean it and a few weeks later it comes back—that most likely means that the panel has actually been damaged and you’re not just going to get rid of the “stain” by cleaning it as it’ll return. It may require touchup paint or even a panel replacement. It depends on the severity of the damage. If this is the case, be certain to check with your installer, maintenance manual, and panel supplier for further instructions on how to address.

Benefits of Metal Panels For Agricultural Applications
Agricultural applications need building solutions that are durable, effective, cost-efficient and versatile, which is why MBCI’s high-quality metal building products undergo rigorous testing to ensure they will meet or exceed the aesthetic and structural requirements of any agricultural building initiative—from general farm facilities to barns, pole barns, sheds, horse stables, riding arenas, ranches, livestock stables, crop storage buildings, machinery storage and garages, animal shelters and more.
Why use metal panels on agricultural applications?
Metal is an excellent choice for agricultural applications because of its durability and longevity, ease of installation on new or existing buildings, its ability to provide a weathertight seal and its low maintenance requirements.
The lifespan of metal roofs and siding can be up to 60+ years. MBCI’s metal panels are built with high-quality material and are backed by some of the industry’s leading warranties. Durable and low-maintenance agricultural steel panels are a perfect fit for the demanding nature of farm and ranch buildings, offering resistance and strength under extreme temperatures, high winds, heavy snowfall, strong storms and other harsh weather conditions. In fact, during hot summers, metal panels can help keep your building cool and energy costs low, while in the winter they shed ice and water to prevent damage. Metal, indeed, has a distinct advantage in its ability withstand the elements and not rot or warp over time.
MBCI’s agricultural metal roof and wall panels are also sustainable—made from recycled materials and are 100% recyclable at the end of the building’s life.
As far as design options go, you can choose from a variety of styles, profiles and colors for your metal barn siding, pole barn siding, metal shed roofing and more. Exposed fastener panels are the most commonly used on agricultural buildings because of their economical pricing and durability. MBCI offers up to 10 different exposed fastened panel profiles to choose from, depending on your preference and the region you’re in. Examples include: Rain Guard®, Perma-Clad®, WeatherSafe®, and Stormproof®, which can be used with DripStop technology to control condensation.
What to Consider
Once you’ve made the decision to use metal for your agricultural building, determining the particulars will depend on a number of factors. Here are some preliminary questions to consider.
- Purpose: What are you using the building for? For instance, is it for equipment storage? Livestock? Is it a hobby building or a workshop?
- Size: How much lot size do you have available?
- Entry points: Where are your entry points? How big do the doors need to be? Do you need certain types of doors? For example, if the building is being used for equipment storage, what are you going to be moving in and out of there?
- Aesthetics: What “look” are you trying to achieve?
As far as aesthetics, metal panels come in a multitude of colors (MBCI offer approximately 25 color options), so you have a lot of versatility with the color scheme for your agricultural project. Traditionally, what we see is a single color for the roof panels and then an alternate color on the walls, and the trim typically matches the roof panel. Another trend is a wainscot panel or a designer panel, which is basically a smaller strip around the base of the building to add an accent color. From there, many customers will wrap that with stone or masonry, too, to make it more decorative. Plus, with the merger of MBCI’s parent company with Ply Gem, our customers now have access to stone products as well.
Metal building options don’t end with roof and wall panels. To that point, MBCI prides itself on being a complete building envelope solution. If a steel frame building is your desire, then MBCI has that covered as well. From new construction to repair and remodel, MBCI offers a vast line of primary and secondary steel structural products and resources to meet the project’s needs. MBCI also partners with many great customers nationwide to offer componentized steel structures that can benefit any agricultural application.
Additionally, with the recent Ply Gem merger previously mentioned, MBCI is better positioned to give customers access to windows, walk doors, stone, and many other components needed to further enhance agricultural projects—all from a single source supplier.
Whether you need a complete structure, metal roof or wall panels, or simply components for a repair or addition, MBCI has the right products and accessories to meet any agricultural building requirement.

Metal Roofing Considerations for Coastal Areas
Whether it is wind speed, sun exposure or the proximity to a coastline, these factors would be the major considerations when choosing metal roofing for a project in coastal areas. The good news is that metal panels can be used in just about any coastal area so long as you find the right product profile and finish that meets your specific requirements to maximize performance given the variables of the environment.
There are a number of special considerations given the environmental conditions inherent to a coastal area, including the impact to paint systems and certain unique maintenance requirements, wind ratings, hurricane conditions and certifications/regulatory product approvals that will limit the panels you can you use within specific coastal areas, for instance Dade County, the state of Florida, and the Texas Coast.
Finishes: The 1,500-Foot Rule
Metal components can be a great roofing choice, even in a coastal area, whether a bay, gulf, or ocean water. Key is how you manage the finish on the products and how close you are to the actual salt environment. Simply stated, if you’re outside of a 1,500-foot range from the coastline or salt water, then standard metal roofing would be suitable, but if you’re closer to the coastline there are special paint options or finishes you’d need for the product to withstand the coastal environment.
At MBCI, we use Flurothane Coastal coil coating system* as our standard solution to the challenge of salt spray and harsh coastal environments. This coating is a premium fluoropolymer (PVDF) system developed for use in the most extreme coastal environments. This system is unique in its use of an innovative thick film primer. The two-coat system has a total dry film thickness (DFT) of 1.7 to 2.0 mils.
Choosing an appropriate coastal finish can also affect your product’s warranty. If, for example, your project is within the 1,500-foot range and you don’t choose the required coastal finish, if the panels were to rust there would be no warranty offered and it could affect your warranty for weathertightness as well.
Suitable Panel Types and Additional Coastal Conditions
Overall, roof failures are the largest hurricane loss due to wind and water damage. For this reason, metal roofing is a highly recommended option for coastal regions where hurricanes and high force winds are prevalent. The appropriate metal panel type for these areas is mainly contingent upon what you want to accomplish. Because MBCI does have high wind ratings for most of our panels, whether it be a screw down (aka through-fastened) panel or a standing seam profile panel, selections should be determined by the complexity of the roof itself and the roof conditions. There are standing seam panels and through-fastened panels that can be approved for both roof and wall applications in many coastal areas.
Also, of note, different types of coastal areas may receive higher wind speeds. There is obviously a wide difference in wind speeds between the East Coast and the West Coast, for example, although both are coastal communities. In an area with higher wind speeds and/or hurricane conditions, you would want to consider panels that achieve higher wind ratings. Since there are many different panel options, and some may not be able to achieve as high wind ratings as others, you should look at what those values would be for wind and what testing has been done. MBCI’s metal wall panels and roofing systems are able to resist and withstand extreme environmental conditions, such as those in Florida or the Texas coast where strict product approval and testing processes are required.
MBCI has panels that meet requirements for Florida Approval, Dade County and Broward County for instance, where you need to have an NOA (Notice of Acceptance) for those county areas, as well as products that are TDI approved (Texas Department of Insurance), which is usually seen in the Texas coastal area.
Additionally, sun exposure and color can have an impact as far as solar reflectance, so that is another consideration. Somewhere like Florida gets a lot of sun yet a coastal area in Washington State would be mostly cloudy. If you are in an area that has more sun, then you may want to consider a panel with a higher solar reflectance value.
If you have metal roofing in a coastal area, you’re going to follow much of the same maintenance as you would on any metal roof, but you would want to inspect it for damage, especially after a wind event or storms. One of the main differences, though, especially if you’re within the 1,500-foot limit where you needed a special finish, is that you’re going to have to do a fresh water rinse regularly on the panels a couple of times a year. What this means is you are basically hosing it off with fresh water to get the potentially corrosive salt spray residue off of it.
