How Insulated Metal Panels Enhance Building Design and Performance

Posted on January 3, 2020May 31, 2023 by Tyler Roose

Insulated metal panels can be a high-performing, aesthetically-pleasing solution for your customers’ building projects—particularly when the weather is colder. These lightweight panels feature an insulating foam core with a metal skin face and offer superior performance and design flexibility. This makes them the ideal choice for many building projects in many industries.

Enhanced Design Using Insulated Metal Panels

In addition to their functional responsibilities, Insulated Metal Panels also need to be aesthetically pleasing. Available in a variety of colors and profile shapes, they help meet the varying design requirements of your customers’ projects. Insulated metal panel finishes resembling traditional construction materials such as precast concrete, stucco, masonry and others are also available. This provides more customization and integration options for customers.

Flexibility and Code-Compliance

Insulated metal panels easily integrate with other building materials such as concrete tilt-up, stucco, brick, single-skin metal panels, glazing and exterior insulation and finish systems (EIFS). They also require less space for insulation to comply with energy codes as compared to other insulating methods. This helps to maximize enclosed space within your customers’ buildings.

Additionally, the use of insulated partition panels gives customers the flexibility to decide how much of their building they want to insulate. These interior panels can help section off portions of buildings that require temperature regulation like offices and storage space. Insulated partition panels can span floor to ceiling up to 20 ft., so in most cases no additional framing is needed for installation.

Strength and Savings

The strength of Insulated Metal Panels allows for greater spanning and load-bearing capabilities as compared to single-skin alternatives. With fewer required supports, these panels easily integrate into building designs without added cost.

And, of course, the advanced polyurethane core of Insulated Metal Panels can help reduce heating and cooling costs. This energy efficiency translates into savings for building owners across the life of the panels.

Superior Performance and Cost Savings of Insulated Metal Panels

Offering superior strength and durability across their lifecycle, Insulated Metal Panels are designed as a long-term building solution. Their consistent, all-in-one air and water barrier design makes them simple to install, which can expedite the project build and minimize schedule delays.

Cleaning Metal Panels Part 2: Quick Tips to Consider

Posted on September 26, 2019May 31, 2023 by Joe Sample

In a recent blog post, we reviewed how regularly cleaning metal panels helps maintain their integrity and aesthetics. Now that you know the importance of this activity, we’re sharing some tips for cleaning metal panels to consider.

LEVELS OF CLEANING METAL PANELS:

These tips for cleaning metal panels are based on general circumstances and get progressively more detailed for tougher jobs. They should not supersede and are not a replacement of the any metal panel manufacturer’s instructions or warranty requirements, including those provided by American Building Components.

Light Cleaning:

For simple cleaning, water and mild detergent is often sufficient. However, never use bleach, as it can change the finish color or interact disastrously with certain metals.

Moderate Cleaning:

For dirt or other deposits that can’t be removed with water alone and require a more complete cleaning, a solution of hot or cold water mixed with detergent is appropriate. An ideal solution is the mixture of 95 percent water with 5 percent of a mild, commonly-used, commercial (non-industrial, non-bleach) dish or laundry detergent added. Diluting the detergent with the water helps ensure the detergent isn’t too strong and doesn’t negatively affect the painted metal surface. Common cleaners for this type of cleaning can include:

Mild laundry detergent
Car wash soap
Mild dish soap
Cold or hot commercial/industrial detergents

Deep Cleaning:

For non-water-soluble residue such as tar, tree sap, grease, oil and adhesives, a solvent or alcohol-based cleaning solution may be required. In this case—since most organic solvents are flammable and/or toxic—handle these according to the cleaner and manufacturer instructions.

Generally, it’s advisable to keep them away from open flames, sparks and electrical motors. Use adequate ventilation, protective clothing and goggles, and—of course—read the manufacturer’s Material Safety Data Sheet (MSDS) for any solvent used for any other specific safety details.

Common cleaners for this type of non-water-soluble cleaning often include:

Alcohols:
- Denatured alcohol (ethanol)
- Isopropyl (rubbing alcohol)

Solvents:
- VM&P Naptha
- Mineral Spirits
- Kerosene
- Turpentine (wood/gum spirits)

WHAT TO AVOID WHEN CLEANING METAL PANELS:

It’s important to avoid using products and tools not recommended by the panel manufacturer that will scrape or grind down the surface coating and leave scratches or other finish damage when cleaning metal panels. This can eventually wear down the finish and leave panels vulnerable to corrosion. Likewise, any misuse or abuse of acceptable cleaning agents will likely automatically void any manufacturer’s warranty for the affected surfaces.

Regardless of the level of cleaning that needs to be done, there are some products and tools that are likely never ideal for use on coated metal panels. These include:

Wire brushes
Abrasives
Steel wool
Sandpaper
High-pressure power washers
Scouring powders
Paint removers
Paint thinners

In conclusion, while the considerations above can help give you and your customers an idea of options available when cleaning metal panels, the importance of understanding and following the specific product manufacturer’s metal panel cleaning instructions can’t be overstated. As a result of diligently following all official instructions and considering these tips, your customers can avoid panel corrosion, staining or other surface damage and retain the integrity and beauty of the metal panel finish.

Cleaning Metal Panels – Part 1: Why it Matters

Posted on August 29, 2019May 31, 2023 by Marc Carolan

Metal roof and wall panels often feature long-lasting and durable finishes available in many colors. These finishes protect the panels and enable them to hold up and look great for decades. However, to maintain their durability and protective properties, cleaning metal panels should be done regularly throughout their service life.

THE IMPORTANCE OF REGULARLY CLEANING METAL PANELS:

Ensure Panel Longevity:

Dirt and residue left on metal panels can damage their protective coating and decrease the longevity of roof and/or wall systems. Likewise, bacteria and mold and mildew build-up can accelerate corrosion to the point where the structural integrity of the panels is compromised.

Protect Panel Appearance:

Stains and algae/lime deposits left on panels for long periods of time can degrade the roof finish to the point where it must be re-coated. Note: re-coating should only be considered if the panels are still structurally sound and doing so wouldn’t void the manufacturer warranty.

Control Energy Costs:

Dirty roof panels can inhibit a roof’s ability to expel heat from a building. If the heat isn’t able to escape through the roof, it can require increases in energy costs to keep the building cool.

HOW OFTEN DO METAL PANELS NEED CLEANING?

An annual cleaning helps keep your metal panels free of tree and animal debris, moss, fungus and other finish-jeopardizing elements. Deep cleaning metal panels only typically needs to be done every 3-5 years, depending on the building conditions and location. This type of cleaning uses stronger detergents that cut through some of the toughest dirt and grime that annual cleans can miss. This includes substances such as tree sap, oxidation and other hard-to-remove substances that often collect on panel surfaces. You may also consider moderate cleaning following weather events and seasonal allergen build-up.

WHO SHOULD CLEAN METAL PANELS?

Above all, follow the panel manufacturer’s recommendations when it comes to selecting who will perform panel cleaning on your building. Before you attempt to clean your metal panels yourself, be sure the product manufacturer recommends it and doing so doesn’t void any warranties.

A professional building surface cleaning company can be helpful as working on top of buildings can pose real safety risks. Your metal panel manufacturer may be able to recommend cleaning professionals who are familiar with their products and warranty requirements, and are practiced in using the correct cleaning solutions and techniques necessary to preserve your metal panels.

THE IMPORTANCE OF FOLLOWING MANUFACTURER MAINTENANCE INSTRUCTIONS:

Metal panel manufacturers usually provide maintenance and cleaning instructions specific to their products, which should always be followed. Manufacturers know the composition of their products and, therefore, which chemical cleaning solutions and techniques are ideal and which will degrade the panels. Neglecting to clean them—or doing so improperly—can compromise the integrity of the finish. Not only can this threaten the visual appeal of the panels, it can also put you at risk of voiding the panel warranty.

Roofing and Snow: Everything You Need to Know – Part Two

Posted on November 13, 2018May 31, 2023 by Ken Buchinger

Additional considerations for working with metal panels in winter.

In part one of our series on metal roofing and snow, we covered five of the most important elements to consider when preparing structures for winter weather. In this post, we’ll review four more ways to prevent unexpected, costly damage of metal panels in winter.

Consider roof material and surface color

Metal roofs absorb heat quickly and radiate it effectively. Darker panel colors can enhance this solar absorption effect, which can save you money year-round. But because UV light can pass through 3-5 inches of snow, when combined with heat loss through the roof, it becomes more difficult for snow to stay solid. To minimize the chance of ice damming, you should ensure your roof system is properly sealed and insulated. If not, ice damming may occur and the melting and re-freezing of snow throughout the day can result in icy layers that promote snow sliding—no matter the roof material or color.

Review weathertightness factors

For low-sloped roofs (less than 3:12), it is especially important for panel seams to be watertight to prevent water (melted snow) from leaking into the structure. This can be problematic when snow gathers and stays on a roof. Architects, designers and specifiers, therefore, should consider using panels that have passed the ASTM 2140 water head test or FM 4471 Appendix G water test. Water-resistant underlayment should also be considered for all roof slopes.

A close-up of this dormer roof illustrates how the impact of sliding ice and snow can damage panel seams.

Consider your roof layout

Design elements like valleys and slope changes cause snow to collect and increases your snow load. Also, when dormers extend from a large roof area and one area is significantly bigger than the other, the structure is susceptible to experiencing unbalanced sliding snow. This imbalance can actually tear open standing seams and displace panels. Also consider that drifting snow may accumulate behind HVAC units, at perimeter walls, and behind solar and photovoltaic (PV) panels.

Ensure Proper Roof Maintenance

One of the best ways to prevent snow and ice issues is to regularly inspect and maintain your roof. In addition to cleaning and inspecting your roof for possible issues, properly removing standing snow and preventing ice dams is a vital part of avoiding damage to your metal panels in winter. This often requires that you get into your attic to inspect for air leaks—the leading cause of ice dams. Read more about how to properly maintain and remove snow from your roof in this blog post.

If an issue is discovered, consult your roofing material manufacturer for recommendations as well as advice on warranty claims. Additionally, you can reach out to a trusted roofing professional in your area. These professionals can thoroughly inspect your roof system to help you determine ways to rectify any potential issues. You’ll want to do this before damage and/or injury occurs and before you pay for sub-par or ineffective repairs.

If you missed part one of this series, click here for our top five considerations. These include managing snow load and sliding snow, preventing ice dams, using retention systems and more! For more information on how metal panels fare in winter weather conditions and for advice on how to winter-proof your roof, reach out to an ABC representative today.

Roofing and Snow: Everything You Need to Know – Part One

Posted on October 4, 2018May 31, 2023 by Ken Buchinger

What to consider when designing and building in snow-prone areas.

While properly-designed metal roofs historically perform well in winter, heavy snowfall can be detrimental to buildings of all kinds. Those who live and work in and around them are also at risk when snow and ice cause dangerous situations. Even though winter doesn’t formally begin until late December, colder weather is upon us. And while you might not be expecting snow or ice yet, keep these roofing and snow tips in mind when designing, constructing and maintaining structures in areas where there’s a chance for snow and/or ice over the course of the year.

Considerations for Snow-Bearing Roofs:

Anticipate Snow Load

Snow accumulates on every roof type, and as this happens, it increases the amount of weight your structure is bearing. This increased weight (snow load) can pose several threats to the structure and those in and around it. For example, when the weight of snow or ponded water from melted snow exceeds the structure’s limits, the roof or even the entire structure can collapse. Be sure you’re aware of the weight your structure can bear and remove snow to keep it within its limits. Consult the International Building Code (IBC) as well as state and local codes for guidance based on your location.

Prevent Ice Dams

Most ice dams are the result of air barrier flaws in buildings. If warm indoor air escapes through the roof floor, it warms the roof sheathing and melts the underside of the layer of snow on top. This water then moves down the slope of the roof toward the eaves, where it freezes into ice. As this process continues, the ice gets thicker and thicker, resulting in ice dams. The presence of these dams allow water to back up and form a reservoir that can cause major damage.

To prevent ice dams, you should:

Seal all air leaks at the attic floor
Ensure proper insulation
Provide adequate attic ventilation

Another tip is to use a peel and stick membrane on the roof deck extending from the eave to about 3’ up-slope from the exterior wall. For more specific details on the ice dam prevention tips above, read our recent blog post.

Prevent Sliding Snow

Gravity can cause accumulated snow to slide down the roof’s slope (shedding), potentially injuring people and damaging property below. Despite this, snow shedding must occur to keep the snow load from accumulating beyond the buildings structural limits. Balancing snow load and shedding is important and requires that you consider geographical and building material and roof design factors.

Ice and snow sliding down the main roof has damaged the roof panels and the valley trim on this connector roof.

Roof slopes of 45 degrees (12:12) or more, can accelerate sliding snow with sometimes immense and dangerous consequences. For example, if snow accumulates and then falls onto an exterior gas line, pipes could rupture. From there, the smallest of ignition sources could set the structure ablaze. In addition, the weight of sliding snow can propel any icicles formed on eaves can be propelled down by the force and weight of sliding snow onto people and property below.

On slopes less than 45 degrees (6:12 to 9:12), low amounts of friction (like on smooth roof surfaces) means it offers less resistance to sliding. Striations and embossing on roofing materials like metal panels add a small 3D profile and improve the resistance to sliding, especially when they run traverse to the slope.

This can get complicated, but in general, installing metal panels with snow retention devices on a steeply-sloped roof is recommended. This approach will naturally shed snow and ice, and protect your structure from excessive snow loads. If you have a low-sloped roof, be sure it’s design supports snow as shedding won’t occur naturally. Including enough snow retention devices from ridge to eave is also imperative for this design.

Use Retention Systems

A variety of retention options, such as snow fences, bars or guards, are designed to make snow and ice melt completely or fall from roofs in small amounts. This helps reduce risks associated with sudden rooftop avalanches while maintaining the clean lines of the roof. It is important that snow retention systems are carefully engineered and properly installed. Models like S-5!’s snow-retention device design resource allow you to input your roof dimensions and expected snow load to adequately engineer snow fence assemblies.

Protect Roof Attachments

This pipe penetration is protected from sliding ice and snow by a small section of S-5! ColorGuard to the panel seams immediately up-slope from the pipe.

The weight of sliding snow can be powerful enough to take off attachments like exhaust vents. To combat this, reduce the shear load by installing rigid vent pipes securely and as high up on the roof slope as possible. If this is not possible, protect the pipes with a snow retention system.

While metal roofing responds well to harsh winter weather, it is imperative to take the time to keep snow, ice and moisture from causing issues. No matter the roofing design or material used, keeping people and property safe from overhead dangers should be a priority when designing, installing and maintain your structure.

In part two of this roofing and snow series, we’ll review additional considerations. It contains tips on roof layout, color, weathertightness and maintenance, which also play important roles in winter weather protection.

Advancements in Metal Roof and Wall Panels

Posted on July 26, 2018May 31, 2023 by Marc Carolan

The evolution of metal roof and wall panels in the steel building industry.

Metal roof and wall panels are commonly used in today’s building industry and are highly valued for their versatility, durability and aesthetic features. This wasn’t always the case, though. Over the last several decades, the metal building industry has evolved and the use of metal panels and coordinated metal building components is now a major boon for builders as it helps them provide on-time, on-budget, attractive project to a wide-ranging customer base.

To meet changing demands and standards, the industry has continued to develop and progress since the Industrial Revolution. This era saw more than just an increase in the use of iron as a construction material. In the late 1880s, metal became a profitable option well-suited for steel-framed buildings, skyscrapers and train stations. During WWII and in the decades that followed, modern steel became the universal standard. Common uses included military shelters, oil storage, churches and private buildings—including landmarks like the Empire State Building.

1940s – 1950s:

During the 1940s and 1950s, industry sales centered around standardized buildings (pre-engineered)—mostly to the agricultural, industrial and government markets. Typically unpainted and unattractive, these metal roof and wall panels simply met their functional purpose. However, their ability to be ordered, delivered and installed quickly and easily made them very valuable.

1960s:

The innovation of pre-painted wall panels in 1959 transformed the metal building industry. Formerly focused on agricultural and industrial end-uses, the additional color options made metal panels more appealing to commercial markets. In the late 1960s, the innovative standing-seam metal roof panel delivered advantages previously unheard of. As seen with American Building Components’ LokSeam® panel, this design features fewer seams that are raised above the panel. With fasteners situated above the panel level, the risk of damage from moisture that can collect there is reduced. Standing seam metal roofs are also designed to allow for expansion and contraction that naturally occurs as a result of changing temperatures. This provided owners, designers and contractors with a high-quality roof that can be specified and used for large buildings. Their low upfront cost and superior performance and lifespan made metal buildings the preferred solution for low-rise, non-residential buildings.

1970s – 1980s:

In the 1970s, the metal panel industry primarily focused on commercial, industrial and agricultural buildings of 10,000 sq.ft. or smaller. In the 1980s, the industry continued to grow in response to customer and market needs. New coating technologies were introduced to provide better corrosion resistance, making metal buildings a more viable long-term option. Technological advances in wind loading for walls and wind uplift for roofs also addressed structural engineering concerns previously held.

1990s:

In the 1990s, metal building construction nearly doubled because metal had proven to be flexible, cost-efficient and time-saving. As a result. the industry expanded to include retail buildings and civil/service facilities, such as schools and hospitals. Emerging metal panel technology, such as snow load solutions, was beginning to be investigated and addressed. In particular, the advancement of computer technology helped create more robust design systems. This enabled manufacturers and contractors to quickly price and deliver detailed preliminary design drawings with greater efficiency and accuracy.

Early 2000s:

The first two decades of this century brought more diverse product and service offerings to the market. These included practical and aesthetic innovations like insulated metal panels (IMPs) as well as new roofing finishes. This decade also saw a new focus on metal building safety in response to dangerous California earthquakes. To help mitigate the risks, research into the structural implications of seismic activity was conducted, resulting in updated building standards. Customer requirements also drove energy performance optimization and engineering guidelines for tapered structural components, and new exterior finishes and styles for metal roof and wall panels were introduced. This included the use of horizontal instead of vertical siding systems and smooth-surface panel faces.

Today…and Beyond:

The dramatic and innovative industry advancements of the past have given way to the full and complete metal panel solutions for a wide range of building types—including unconventional ones like custom residences—that we enjoy today. Continued research, partnerships and collaboration are further driving industry expansion and diversification—a trend that shows no sign of slowing.

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.

Proper Ventilation for Metal Roofs and Walls

Posted on December 13, 2017May 31, 2023 by David Lester

Selecting metal roof and wall panels is a strategic investment for the life of a building. To protect their investment, it is key that your customers ensure the proper ventilation system is installed. Optimal air movement not only promotes temperature regulation and energy efficiency but also reduces the risk of moisture-related issues like condensation build-up. Here, we look at some of the main ventilation considerations and resources your customers need to ensure success.

Why is proper ventilation important?

Proper ventilation helps optimize the performance and efficiency of metal buildings by:

Controlling condensation

Condensation can wreak havoc on metal, causing corrosion, reduced thermal performance of insulation, mold and mildew growth, and even insect infestations. For example, in warm and humid areas, outside air that enters a building without moving through a ventilation system can bring with it large amounts of humidity. This humid air can create an uncomfortable environment, accelerate panel weathering and increase the possibility of mold growth. This issue is worsened when the outside temperature falls below the inside temperature, creating a perfect breeding ground for condensation development.

Regulating temperature

Regulating and maintaining ideal interior temperature can help cool the building in warmer months, keeping the structure comfortable to occupy. Temperature regulation also helps protect the integrity of the building from excess (and premature) metal panel expansion and contraction. This movement can weaken the integrity of fasteners, which are designed to keep panels from detaching/pulling away from the substrate.

Preserving air quality inside the building

Proper ventilation helps remove volatile organic compounds and other air pollutants that are detrimental to human health and productivity. The Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) have published guidance on indoor air quality standards in commercial/institutional buildings. These standards help determine ventilation needs that need to be met to ensure compliance.

Who Needs Ventilation?

As expected, most structures require proper ventilation in accordance with their geographic location, contents and/or building end-use. Structures housing chemicals or moist substances require more ventilation than those storing dry goods in relatively arid environments. Ventilating a building that stores ceramic in the desert is very different than ventilating an indoor sauna in practically any geographic location. Agricultural facilities in particular must employ proper ventilation to mitigate the dangers posed by ammonia and other corrosive airborne fumes. (See our Animal Housing blog post for more.)

How to Ensure Proper Ventilation:

Similarly, the ideal amount and type of ventilation your customers need depends on their building’s unique specifications and end use. Generally, structures larger than 2,400 sq. ft. may require more than one type of ventilator to allow air to move between them (cross-ventilation). Structures that house people, animals and/or valuable material also benefit from cross-ventilation using ridge vents near the roof and a louver vent located closer to the structure’s floor. In these cases, it is recommended that your customers work with design professionals and building engineers who can help determine the building ventilation requirements. These professionals can recommend the appropriate, high-quality metal panels and components that suit the unique requirements of their project.

So, what ventilation options are available for your customers? Ventilation solutions fall into two main categories: natural (unpowered) and mechanical (electrically assisted):

Natural ventilation methods include installing a ridge and eave vents that enable air to circulate naturally through the building. Your customers can also use vents that capitalize on the natural vacuum created when air moves quickly over angled surfaces like roofs. The lower pressure in this vacuum draws air out of the building—most often through ridge vents. This choice will depend on your customer’s aesthetic preferences and/or installation location limitations.

Mechanical or power-assisted ventilation helps draw more cubic feet of air into and out of the space per minute. Powered fans with curved blades and/or louvers are often used to achieve greater air flow. As previously noted, air flow is vital in preventing condensation, so this is particularly helpful in naturally humid environments.

Conclusion

In conclusion, proper ventilation is a critical component of any high-quality building. As metal panels are becoming more popular, understanding how to achieve an effective ventilation system can help ensure the success of your customers’ building projects.

Metal Roof Pitch Part II: Panel Selection for Your Building End-Use

Posted on October 18, 2017April 29, 2024 by Ken Buchinger

In part one of our series on metal panel roof pitch, we looked at the engineering and strength considerations that need to be taken into account when designing or specifying a building. In part two, we’ll review how to make the right metal panel selection for your building end-use by looking at the building type and roof pitch to find the optimal combination of form and function.

Types of roof panels:

Different types of metal roof panels are better suited for certain roof pitches and this mostly has to do with panel rib height and how they’re seamed together. For instance, the lower the pitch, the taller the rib of the roof panel needs to be in order to optimize water carrying capacity. Also, the lower the pitch, the slower water runs off the roof; combined with wind pressure, this can hold water at the eave. As an example:

On 2:12 and lower pitches for commercial/industrial jobs, weathertightness warranties will use a mechanically seamed panel because it creates an impenetrable lock that keep water from seeping between the panels. Seamed panels can be thought of as more hydrostatic (resistant to water), whereas non-seamed panels are hydrokinetic, i.e., water runs off of them, but they are not designed to be a water barrier.

Building Type and Use:

Whether residential, post-frame or commercial, structures follow general design criteria regarding metal roof slope, based on to the building type and use. For instance:

Gabled v. Hipped: gabled roofs provide more interior headroom while with hipped roofs, endwall sheet height can be reduced, making for easier ordering and installation as you don’t have to cut/miter the sheets.

Residential v. Post-Frame and Commercial Use: While it can generally be assumed that thicker-gauge panels are stronger, the type of building construction, location and end-use can affect the choice in panel thickness. Residential roofs generally have steeper slopes (often due to aesthetic sensibilities), while commercial and post-frame buildings will typically have a shallower pitch to increase the strength of the building. Buildings such as pole barns, post-frame buildings, warehouses and garages can require roof panels to span longer distances between supporting trusses and purlins and therefore require thicker panels to ensure the roof is structurally sound and can aid in reducing the chance of collapse under the weight of snow and water—particularly when the roof pitch is low. For smaller buildings—like residences—with supporting trusses and purlins that are typically closer together, thinner panels can be used in conjunction with thicker trim for an economic, structurally ideal residential metal roofing system. See our blog on metal panel gauges for more.
Economics: When a roof has a shallower pitch, less material is needed to cover the same roof span. This can be more economical since fewer square feet of material needs to be purchased, or at least help in offsetting the cost of the thicker panels commonly used on low-slope roof—a consideration often important to companies with multiple properties. Likewise, while more material may need to be purchased for a high-sloped roof, you may be able to buy thinner, less expensive panels since high-slope roofs don’t typically need to be able to support heavier loads like low-slope roofs do.
Aesthetics: Traditional residences typically feature a higher roof pitch while this may be less important to commercial building owners. However—from a functional standpoint—thicker panels can be more forgiving of installation errors such as over-tightened screws and aren’t as likely to transfer waves and bumps in sheathing.

Solar Panels and Roof Pitch:

The geographic location of a structure will determine the angle at which the solar panels should be installed. Generally. the closer to the equator you get, the lower the slope the solar panels can tolerate as roofs closer to the equator have more consistent exposure to sunlight as compared to those farther away. If you plan to add solar panels to your metal roof, be sure to check the Solar Reflective Index (SRI) values and minimum slopes set by the ASTM and local governing codes. These standards will advise adequate slope based on your location as well as help control things such as heat island effects, etc. For more information on solar reflectance and how it is affected by the color of your metal roof panels, see our blog post on cool metal roofs.

Conclusion:

Roof slope is a factor that affects many decisions when it comes to any metal building roofing project regardless of the building’s end use. When embarking on any metal roofing project, be sure that the panels you’ve selected meet local building codes and are produced by a quality manufacturer with knowledge and experience designing for different applications to ensure you get exactly what you’re looking for.
