Selecting & Applying Metal Roofing Touch-Up Paint

Posted on September 15, 2020May 31, 2023 by Martin Thompson

Our metal roofing panels are designed for durability, featuring a baked-on paint finish that covers the Galvalume®-coated steel surface. This helps to preserve the look and functionality of your metal roofing panels for decades with minimal maintenance. Over the life of your metal roofing panels, however, it is possible that the baked-on paint finish can be damaged. For minor scratches, you are able to use touch-up paint to preserve the aesthetic appeal of your metal roof. Learn more about selecting and applying metal roofing touch-up paint.

What Causes Scratches & Dents?

Metal roofing panels are most commonly damaged during the installation process. To avoid scratching or denting your metal roofing panels, it’s important to store them properly and use caution when unpacking and installing them. Store them at a slight angle in a dry location that is out of the way of foot traffic and ongoing construction. Avoid dragging panels across each other when unbundling to prevent damage to the paint coating.

After metal roofing panels have been installed and before the installer leaves, walk around the building to look for scratches and dents within normal view. Address these issues with your installer.

After the installation process is complete, there are additional considerations to protect your metal roof from damage. Keep trees trimmed to prevent overgrown branches from scratching your metal roof panels. Additionally, use caution when walking on the roof or using tools as these activities could damage the paint coating. Check your roof for damage at least once a year as part of your annual maintenance routine to keep it in good condition.

Assess the Damage

If you find a scratch during routine maintenance or a post-installation check, start by assessing the damage. How noticeable is the scratch? Is the panel scratched down to the bare metal? These are important questions to ask when deciding whether to use touch-up paint or replace the panel altogether.

Use touch-up paint for light scratches that only affect the paint coating or for hairline scratches down to the bare metal. touch-up paint fades more quickly than the baked-on paint coating, especially with bright or dark colors. As a result, covering a sizable area with touch-up paint could create more of a problem as the touch-up paint begins to fade over the next couple of years which would be more noticeable than leaving it alone. If your panel has large scratches or gouges that go down to the bare metal, consider replacing it instead.

Choosing Touch-Up Paint

When choosing touch-up paint for your metal roof, it’s important to make sure that it’s compatible with the existing paint coating. The best way to do this is by purchasing touch-up paint from your metal roof panel manufacturer. Most manufacturers offer small containers of high-quality paint that are designed to match the color of your existing roof panels.

How to Apply Touch-Up Paint to Metal Roofing

When applying touch-up paint, make sure to read the specific instructions provided by your manufacturer.

In general, you will complete the following steps to apply touch-up paint:

Make sure the surface temperature of your roof is 50 F.
Clean the area by wiping it down with isopropyl alcohol. Make sure the surface is dry and free from contaminants before moving on.
If the bare metal of the panel is showing, apply acrylic primer.
Apply touch-up paint to the area using the dobber (or a small artist brush). Multiple coats may be likely to achieve the desired film thickness.
Touch-up paint should be tack free within 30-45 minutes.
It should dry completely within 24-48 hours.

Benefits of Metal Panels for Agricultural Buildings

Posted on May 26, 2020May 31, 2023 by Joe Sample

Metal panels are ideal for agricultural buildings, including those that house livestock, such as cattle, hogs and poultry. They’re durable and offer flexibility in design so you can create an agricultural building that is functional and aesthetically pleasing. Read below to learn more about the benefits of choosing metal panels and special considerations for animal confinement.

Why do so many agricultural buildings use metal panels?

Durability: Metal panels are designed for durability. They can withstand high winds and heavy snowfall. They’re also hail resistant, featuring a class 4 rating. Unlike wood, metal panels are resistant to damage from termites and other insects. Metal is also noncombustible.
Longevity: Metal panels last three to four times longer—up to 60 years. Unlike corrugated fiberglass panels, metal doesn’t get brittle after years in the sun.
Cost Savings: Metal is a much more cost-effective material than wood because it doesn’t need to be replaced as often. The durable design of metal panels also saves money on maintenance.
Sustainability: Our metal panels are made from recycled materials. They’re also 100% recyclable at the end of your building’s life. Choose from a variety of cool roofing colors that are designed to reflect the sun’s heat instead of absorbing it into your agricultural building.
Ease of Installation: Metal panels can be cut to the nearest 1/4 of an inch for easy installation. Most panels offer three feet of coverage which is more time-efficient than pounding out shingles.
Design Flexibility: There are a variety of options to choose from when it comes to metal panels. We offer a broad selection of styles, profiles, colors and finishes.

The common panel profile used for this application is Imperial Rib® . It’s designed for durability with two minor ribs which give it strength. It’s also formed with a round top which pushes away moisture.

Metal Panels for Livestock Shelters

Animal confinement imposes specific challenges on panels that aren’t required considerations for residential or commercial uses.

When considering metal panels for a barn or other animal enclosure, here is what you should keep in mind.

What makes animal housing such a challenge?

Animal waste has high ammonia content that can start to corrode metal in as little as five years. With roofs, this corrosion is fueled by airborne fumes; on walls, the culprit is manure or dirt lying against the panels for extended periods. You can minimize both problems with good ventilation and regular maintenance, including keeping the panels clean and immediately repairing any damage.

Important Considerations

Panel Coatings: More people are opting for Galvalume panels for their livestock housing projects than ever before. And while Galvanized panels perform better than Galvalume in high-ammonia environments such as hog confinement, Galvanized panels are susceptible to white rust (chalking) if exposed to water prior to installation, which is not an issue with Galvalume panels.

For this reason, many are pairing Galvalume panels with a protective, self-adhesive moisture barrier like ABC’s Drip Stop product, which is applied to the panel’s interior before it is roll-formed. This membrane absorbs moisture when relative humidity (RH) is high, and then releases it back into the atmosphere when the RH falls, thereby preventing the damaging moisture from directly touching the panels. For hog or cattle barns, where dirt and manure tend to pile up against walls, another protective option is to install a polycarbonate panel on the inside of the metal wall panel to reduce contact, making the metal panels easier to keep clean.

No matter which panel you choose, be sure you understand how the coating is measured to that you optimize the durability and long-term corrosion resistance. The best options are the G90 Galvanized or AZ55 Galvalume panels, which have been compared in this article.

Panel Thickness: The 29-gauge panel is most commonly used for animal confinement, but as mentioned in this article on metal panel gauges, nominal 29-gauge panels come in a range of actual thicknesses. For best results, look for one that’s at least .015 inches thick.
Design: The design of animal confinement structures is important and can have major impacts on the viability of the building. Dropped ceilings with sophisticated ventilation systems are said to increase efficiency and satisfy environmental run-off inspections, therefore maximizing return on investment. These structures can also be designed to help eliminate ammonia fumes and corrosion- common occurrences in buildings with poor air flow.
Warranty: As with any purchase, it’s important to check the warranty exclusions when selecting any kind of panel for your projects. For instance, the warranty on a Galvalume panel may not apply when it’s subjected to animal waste or other corrosives. Again, good ventilation and regular maintenance will minimize the chance of problems.

Metal Panel Color Selection—What to Consider

Posted on May 31, 2018May 31, 2023 by Candy McNamee

Choosing a metal panel color can feel daunting these days. With the number of available metal building colors having expanded from the usual white, tan and Galvalume to more than a couple of dozen options, where do you begin? What factors should influence your decision? Read on for recommendations on key questions to ask to help you make the best decision for both the desired aesthetic as well as longevity, durability and energy efficiency of your metal project.

What colors are metal products available in?

This is the most obvious consideration and can be answered with a simple search of the metal product manufacturer’s website. Authorized dealers also often have physical metal panel color charts, samples or chips from metal product manufacturers for in-person review. While metal panel color options used to be limited to standard stock colors like white, tan and Galvalume, today, many manufacturers are able to offer many more color options outright as well as additional custom colors. These new metal panel color options now include metallic paints, as well as ones with metal flecks that add sheen and sparkle, giving the panel color more depth and durability.

How can I be sure I’m getting the exact metal panel color I think I’m getting?

Upon request, most metal panel manufacturers are more than happy to provide actual color chips so you can see the exact color in person. While the chips on color charts are a close facsimile, getting color chips from the plant is ideal to ensure a perfect match. Additionally, you can view images of completed projects on the manufacturer’s website as seen in ABC’s Project Gallery. This section not only shows you photos of real-life building projects using our metal products so you can see how colors look in different combination and on different building types, but it also provides details on the products and colors used with additional resources to help you make your selection.

In addition, ABC’s Color Visualizer helps you envision your actual project before you even order your metal panels. You can upload your own photo or choose from our sample project photos to pick your ideal panel type and color. While it’s useful to review the manufacturer’s website and color visualization for project images and ideas, keep in mind that colors may look a bit different on your computer than they do in real life.

How to select the right color for optimal energy efficiency?

Cool metal roofs have been shown to be among the most sustainable and energy-efficient choices out there. They are designed to reflect more of the sun’s energy (and heat) back into the atmosphere to keep your building cooler and reduce your air-conditioning bills. (Read more about cool metal roofs in our blog post.)While lighter colors are generally the best option to optimize cooling effects, it should be stated that improved energy performance is a result of much more than just the roof’s color. The Cool Roof rating of paints and coating systems used by metal panel manufacturers are generally listed with the color choices on the manufacturer’s website. For detailed information, a great resource is the Cool Roof Rating Council, which maintains a products directory that lists solar reflectivity and thermal emissivity values for many roofing brands.

ABC offers the most sophisticated silicone polyester coating paint system in the industry. It offers optimum exterior protection and superior resistance to chemical corrosion and ultraviolet radiation, and most of our paint coatings are ENERGY STAR^® qualified.

Can I paint over my metal panels?

If you’re considering painting your metal panels, trim or accessories, you should first check with the metal product manufacturer to ensure you won’t be voiding any warranties. You can also ask the manufacturer about touch-up paint and the correct way to apply it if small corrections need to be made. If you do decide to completely re-paint your panels, it’s best to get the panel manufacturer’s recommendation on the best paint and application products/methods to use to ensure you don’t damage the steel underneath the paint.

What if my paint isn’t performing the way I expect it to?

Most manufacturers offer a limited warranty on their paint systems. Before you buy, be sure you understand the limits of the warranty. If you think your situation warrants a claim, take pictures of the product and send them to the manufacturer to start the process. Do not attempt to correct or cover any issues as this will likely void your warranty. The manufacturer will likely send someone out to look at your material and will keep you informed throughout the process.

Armed with the right questions, resources and, hopefully, color charts and samples, choosing a color for your new metal roof can be an exciting part of the process. Your job is to take the time to review the options to make the most practical and aesthetically appropriate decision. ABC representatives are always ready with the resources and information you need, so feel free to contact one of our team members with your questions.

Maintaining, Cleaning & Repairing Metal Panels

Posted on September 23, 2016May 31, 2023 by Tyler Roose

Understanding the maintenance requirements of your metal panels is essential to maximizing the longevity of your investment with the least amount of hassle. While metal panels have been engineered to provide decades of trouble-free protection, they can suffer damage from the build-up of debris as well as storm-related traumas like hail stones, falling branches and ice dams. To extend the lifespan and strength of metal panels, maintenance consists mostly of preventing and correcting these issues.

The importance of regular inspections

Regular inspections are critical to identifying damaged panels and accumulated debris that can trap moisture, causing corrosion over time. To prevent this, a visual inspection should be performed in the spring and the fall of each year, as well as after major weather events to identify issues. Take a walk around the structure and look for leaves, branches and other debris piled up on the roof, including in valleys, gutters and downspouts, as well as behind chimneys and/or other protrusions. While you can perform this type of inspection yourself, please keep in mind that metal panels—particularly metal roofs—should be professionally inspected every four to five years depending on your geographic location. If you live in a coastal or humid area more prone to corrosion and rust, professional inspections should be done more frequently to prevent the rust from spreading and causing structural damage to the panels.

In addition to debris, keep an eye out for scratched or dented areas, as well as for loose screws and seams that look like they are separating. (If you can’t make out the details from the ground, try using a pair of binoculars.). Use the manufacturer’s recommended touch-up paint to correct scratches as they can quickly degrade the surface protection and jeopardize the longevity of metal panels. If the panels have separating seams or holes, first check to see if the repair is partly or fully covered by your warranty. Unless you are experienced in metal roof repair and possess a thorough knowledge of the products and techniques that can be used without voiding the warranty, it is recommended that you engage a metal panel repair specialist to make the repairs. If you decide to undertake the work yourself, it is also important to remember that these fixes are, at best, temporary and should be addressed by a professional recommended by the metal panel manufacturer.

Cleaning metal panels

Keeping metal panels clean is one of the best ways to ensure they last as long as possible. When cleaning metal roofs and walls, using a non-pressure cleaning method with detergents recommended by the metal panel manufacturer is ideal. It is not advisable to use metal tools such as rakes to remove debris. This is likely to scratch the paint, reducing the panels protection from the elements and other damaging factors. Using a leaf blower to remove debris is a common choice, but a long-handled push-broom or a telescoping pole with a window cleaning brush will also do the job. Ideally, the tool should be one that lets you do the removal from the ground, but if you absolutely must walk on the roof then only step on the flat areas. If there are areas you can’t access yourself—particularly slanted areas that have been made slippery with cleaning solutions—hiring a professional service to do this once or twice a year is the safest option.

To reduce the chance of further damage and keep your panels cleaner over longer periods of time, trim tree branches as far back from the building as possible. This is especially important for large, unhealthy branches that could break off during high winds and cause damage.

Proper snow removal

There are—of course—considerations that must be made for metal buildings located in colder climates. After a winter storm, it’s a good idea to remove standing snow from the roof. This is doubly important on older homes where poor attic insulation can lead to ice dams. An ice dam forms when heat escaping from inside the attic warms the roof and melts the bottom layer of snow. The snowmelt then re-freezes, creating a dam that traps water which can work its way into seams between panels and around flashings.

Warranty considerations

It’s always smart to reference the metal panel manufacturer’s warranty to be sure you don’t use any products or tools that will void your warranty. They should also provide instructions and advice specific to the panels and application(s) you’ve selected to ensure you get the most out of their products with the least hassle.

Your Guide to Steel-Curtain Roll-Up Doors

Posted on July 29, 2016March 24, 2023 by Jessica Taylor

No building is complete without a door. In this blog, we investigate steel-curtain roll-up doors and how they deliver form and function across a wide variety of uses.

What are Steel-Curtain Roll-Up Doors?

You see them everywhere. They’re used at your local schools, recreation and retail centers, and government, medical and office buildings. They provide access and security for storage units whether applied in backyard sheds, residential garages or commercial storage facilities. And, they are also an integral part of agricultural structures, transit stations, freight buildings and warehouses.

Made of a curtain (sheet) of durable, secure steel and designed to provide quick, easy access to both commercial and residential buildings, these doors open by traveling vertically, but gather into a roll at the top of the door instead of sliding along tracks. And while they can be used in a myriad of applications, with so many door options available in the marketplace today, why are so many people opting for steel curtain roll-up doors?

Why Steel Roll-Up Doors?

Long-term Value:
Roll-up doors made of steel are generally less expense to purchase initially and they save money over the course of their lifespan. Not only do they last longer, but they also require fewer, less expensive repairs and are more durable than wood, aluminum or fiberglass products—particularly in challenging environments. In addition, steel is more energy-efficient, saving on heating and electricity costs throughout the year.

Security:
Exterior doors are inherently the most vulnerable points of many buildings, so reducing the likelihood of theft, fire, vandalism and contamination is the best way to keep your property secure. More impenetrable than doors made from wood, fiberglass or aluminum, steel doors with standard stainless steel latches are better able to protect against unwanted entry, fire, noise, vandalism and contamination from exterior elements, providing reliable security and peace-of-mind.

Durability:
Steel is a resilient material manufactured to protect against extreme weather conditions and harsh usage environments. Unlike doors made from other materials, steel roll-up doors can endure the wear and tear of heavy traffic usage and can be outfitted with rust-resistant components including spring coatings and bottom bars to further extend their longevity.

Longevity:
While wood doors are susceptible to warping and rotting, aluminum doors can quickly become dented and fiberglass can easily crack—all of which require replacement—with proper installation and maintenance, metal doors can last 30 years or longer. The high-quality primers and paint coatings used on steel doors protect against chipping and scratching, keeping the doors looking better longer.

Easy Maintenance:
Steel roll-up doors require little-to-no maintenance and are easily replaceable—making them one of the most reliable, cost-effective options in the industry. ABC’s doors are unique in that they feature gear-driven tensioning brackets that ensure safe and easy adjustments that can be made on site and with minimal down time.

Appearance:
Steel roll-up doors are available in a wide variety of sizes, styles and colors. In addition, manufacturing improvements and advances in coating and paint products enables customization to suit even the most unique aesthetic requirements.

Space-Savings:
Because roll-up doors open vertically and are gathered into a roll instead of sliding along tracks, they take up little overhead space while enabling convenient and easy access.

How to Select the Right Steel Roll-Up Door:

Whether you are replacing doors on an existing building or sourcing them for a new project, be sure to consider the below factors before purchasing:

Use:
The door you need will depend on its intended use. Light-duty doors are manufactured to meet the specific and unique demands of small structures, portable buildings or recreational facilities while heavy-duty doors meet the needs of more demanding environments like commercial freight and utility buildings, warehouses and agricultural facilities.

Environment:
It is vital to consider your geography when selecting steel roll-up doors. If your project is located in a region susceptible to high winds from weather events including hurricanes, tropical storms and tornadoes, a wind-rated door tested in accordance with International Building Codes and that complies with your insurance requirements should be considered. Check both local and national building codes to understand if you need wind-certified doors, which can dramatically reduce maintenance and replacement costs as well as minimize downtime.

Warranties:
Be sure that you are familiar with and fully understand the warranty options available on the products purchased. It is common for doors and door components to be covered by a product warranty, while the coil coatings and paint are warranted under a second that should include considerations for film integrity as well as both chalk and fade.

Decoding Your Warranty: Paint Chalking

Posted on April 29, 2016April 29, 2024 by Heather Hollis

The third and final element of our “Decoding Your Warranty” blog series covers paint chalking. As with fading, chalking is an expected occurrence with any paint system that is subjected to outdoor exposure, and while it may be preferable to other issues such as cracking or peeling, it is still important to the metal roofing industry and its customers. As a result, similar questions should be asked about how this is addressed in paint system warranties to ensure chalking isn’t the cause of premature damage to your metal roof system.

What is paint chalking?

Also referred to as “powdering”, chalking happens when the resin (binder) of the paint system is compromised. The resin is the substance that holds the paint pigment together. It also ensures the color is evenly distributed and provides glossiness, durability and flexibility. In addition, resin has the very important job of adhering the pigment to the metal surface it’s applied to and protecting the finish against damage.

When the resin at the surface of the paint finish deteriorates, most often as a result of exposure to ultraviolet (UV) rays, the embedded pigment particles lose their adhesion to the paint film (resulting in color fading) and the resin particles take on a white (chalky) appearance that is easy to wipe off of the surface. In addition, chalking can erode the film resulting in a loss of substrate protection and run down onto the underlying structure, further degrading the appearance of your structure.

How can you protect against paint chalking?

Climates that are exposed to more intense UV rays for longer periods of time will experience chalking sooner as the environment plays a big role in how painted metal will perform. While you may not be able to control how much UV or moisture exposure your roof gets, you can choose a paint system that is not over-thinned or over-spread and that uses high quality components. ABC’s Signature® 200 system incorporates a 30 percent SMP Resin—one of the strongest in the marketplace—to help reduce the amount of chalking experienced.

Similar to the fading section of the warranty, paint system warranties allow for an acceptable amount of chalking. Chalking is measured in accordance with the standard procedures as defined by the “Standard Methods of Evaluating Degree of Chalking of Exterior Paints”, ASTM D4214. ABC guarantees the level of chalk on vertical panel applications will not chalk in excess of a numerical rating of eight (the higher the numerical rating, the better) for 30 years for our Premium paint system colors and 25 years for our Select40 paint system colors. For non-vertical panel applications, ABC guarantees a rating of 6 for 30 years for our Premium paint system and 25 years for our Select40 paint system. Consumers should be aware of these numbers, and expect them to be expressed in sample warranties.

Decoding Your Warranty: ABC Paint Film Integrity

Posted on March 23, 2016March 24, 2023 by Tim Wells & Bob Swoger

With a 40-year limited paint system warranty, the ABC Signature^® 200 offering represents one of the most sophisticated siliconized, modified polyester (SMP) paint coating and warranty protection products in the industry. But do you understand what it means to have a 40-year warranty?

To comprehend your coverage options, you first need to know what a “40-Year Warranty” means in the industry. This limited warranty covers the film integrity of the paint system used on your wall and roof panels in case of cracking, checking and peeling for a period of 40 years. Most manufacturers of metal roofing have this basic warranty available, however—as with any warranty—the most miniscule details can impact the overall effectiveness and value.

To select the right protection for roofing or building projects, ask questions to confirm your understanding of the warranty coverages and options before purchase. Some pertinent questions to consider include:

Are there any exceptions to the warranty?
Are all colors covered?
What are the limitations of the warranty?
What are the financial implications of not abiding by the warranty?

The answers to these questions and additional coverage information should be readily available and provided to you by the supplier. Keep in mind that all 40-year warranties—while generally similar—are not equal; it’s essential to thoroughly investigate the product’s warranty details to ensure the best property protection is received.

We encourage you to view ABC’s warranties on our website. You can also learn more about the proper handling of ABC’s metal panels by reading the product installation manuals. The precautions in the manuals can help save time, heartache and, of course, money.

What’s next?

How well paint adheres to the substrate is not the only concern for many metal wall and roof panel consumers; homeowners often ask us about the fading of the paint system and the factors that should be considered when purchasing.

In the next installment of our “Decoding Your Warranty” blog, we will discuss fading in more detail and provide insight into this commonly overlooked factor in warranties.
