As with any kind of roof, proper maintenance is integral to protecting against hurricane damage. In part 1 of this series, we reviewed how choosing metal roofing can help prevent wind damage to homes and businesses. And while choosing metal panels as a roofing solution is the first step to damage prevention and increasing roof longevity, there are additional precautions your customers can take to protect their investment.

Professional inspection

Prevention is key. To maintain the strength and durability of metal roofs, your customers should have a licensed metal roofing professional inspect it regularly. While your customers can manually inspect their roof themselves, a qualified roofing inspector can thoroughly examine it, identify areas of concern and provide a detailed report including roof life expectancy, photos and repair estimates. Professional inspectors can also make hurricane preparedness recommendations based on your customer’s roof type.

Ensure all fasteners are secure

Fasteners are the key to preventing roof uplift as a result of high winds. Be certain the roof is properly fastened to the truss and that the correct fastener type, diameter, length and thickness are used. Consider the thickness of the panel, substrate and any other materials between the panel and truss to when selecting fastener length to ensure roof panels are secure. (Screws often need to be triple the length to accommodate the thickness of what’s being screwed down.) Additionally, although placement of fasteners may seem like a minor detail, screw pattern can actually be a major factor in a roof’s structural integrity. Be sure to follow the panels manufacturer’s instructions to the letter during installation.

Check for rust, loose screws and flaking paint

When rust develops on metal, it can accelerate degradation, compromising the integrity of your customer’s structure and leaving it vulnerable—particularly in inclement weather. While ABC offers Galvalume^® metal panels that prevent rust from occurring, standing water and heat from direct exposure to the sun can degrade this protection over time. Therefore, it is important that customers regularly check for rusty and loose screws as well as flaking paint which can also cause rust development. If rust is found, advise your customer to contact their roofing contractor for repair options.

Install hurricane straps

An added layer of protection from high winds, hurricane straps (or roof tie-downs) securely tie rafters to load-bearing walls. Made of galvanized metal, they can attach to most roof types, protecting it and the structure beneath. Hurricane straps can also help keep a roof from detaching and causing damage to nearby structures and objects. Many homes already have them (depending on how old the roof is), but even structures with hurricane straps should be checked to make sure they were installed properly.

Add roof reinforcements

Although most metal roofing is resistant to wind-related damage, adding reinforcements can decrease the likelihood of damage. This is particularly true if your customer’s building project is located in a hurricane-prone area. To reinforce their metal roof, your customers can add sturdy overlapping materials on top such as heavier metal panels or two-by-fours. A professional roofing contractor can advise your customer on the best reinforcement option for their structure.

Brace gable ends

Gable ends experience a lot of exposure to high winds, making them vulnerable to wind damage. If your customer’s structure has a gable end, they should ensure that it has been solidly built and appropriately braced.

Trim your trees

Trees that hang over your customer’s roof can be dangerous any time of year, but particularly during a hurricane. Falling tree limbs can cause severe roof damage, allow water into the structure, cause electrical issues or even injure someone inside. Trimming trees to is an easy way to prevent damage and injury.

Perform an interior inspection

If your customer is experiencing issues with their roof, chances are that they will also see damage inside their structure. Your customers should be aware of any spots, stains, peeling paint and daylight seeping in. These are all serious indicators of a compromised roof and should be addressed immediately.

Secure the Yard

Unsecured items around your customers’ property can become a major threat to your customer’s home or business during a hurricane. With strong winds, patio furniture, trampolines, grills and even potted plants can become dangerous projectiles. If these objects strike your customers roof, they could cause severe damage. Customers should move small items inside and secure larger items with rope or zip ties.

Choosing metal panels as a roofing solution is the first step to preventing building damage during hurricane season. There are, however, extra precautions your customers can take to prevent damage and protect their investment.

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.
