Metal Roofing & Hurricane Season Part 2: Tips to Help Your Customers Protect Their Metal Roof

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.

Metal Roofing Gauges: What Are The Best Gauges For Metal Roofs?

When your customers decide to use metal panels for their building project, they’ll need to make several decisions to choose the best panel. One of the first decisions they’ll make is what gauge or thickness they need. There are a variety of metal roof and wall panel profiles to choose from, and they are all available in several gauge thicknesses … but what does that really mean to your customers and how does that affect your business?

Metal Panel Gauges: Are you getting what you pay for?

Metal Panel Gauges Deciphered

U.S. manufacturers express the thickness of metal panels as their ‘gauge’, with 22-gauge being the thickest and 29-gauge the thinnest of traditionally-sold metal roof and wall panels. Each gauge represents a nominal decimal range. For example, a 26-gauge steel panel can range between 0.0179 and 0.0217 inches thick according to a University of North Carolina at Chapel Hill resource.

This means that while a 26-gauge panel from one manufacturer could measure 0.027 in. thick, a 26-gauge panel from another manufacturer could measure only 0.0179 in., but both are sold as 26-gauge panels. Although those seem like small numbers, they represent a noticeable difference in panel stiffness and strength.

So how do you and your customers know if the metal panel manufacturer has used thinner sheeting and made up the difference with a coat of paint? When ordering inventory, you should look beyond the gauge number to the manufacturer’s specifications on metal thickness. This will give you peace of mind that you’re providing your customers with the gauge they’re paying for and the quality they need to get the job done.

 

Costs of 26-Gauge Panels vs. 29-Gauge Panels

Expect to pay more for thicker panels. The cost of a 26-gauge product will be about 15 percent higher than a 29-gauge with the same profile from the same manufacturer. While some people insist that the extra cost is always worth it, that may be misleading. Yes, thicker panels are stronger, but the importance of that added strength depends on the type of building construction as well as the customer’s priorities and location.

 

When To Choose a Thicker Metal Roofing Gauge

There are instances where thicker gauges always earn their keep. The most common of these is the post-frame building, or pole barn: an open-framed structure used for barns, garages and warehouses. Post-frames generally lack structural sheathing, so the roof and wall panels must span between the supporting trusses or purlins. Because 22-, 24- or 26-gauge sheeting is thicker, and will, therefore, remain more structurally sound over a longer span than a 29-gauge, the building needs fewer supports, which saves your customers money. For post-frame structures like this, it is important for your customers to consider the potential snow load the roof may need to support when choosing the metal panel gauge. Lighter-gauge (thicker) panels may save your customers from structural collapse in the winter months!

Lighter gauge (thicker) metal is also more forgiving of installation errors such as the over-tightening of screws, and it won’t be as likely to transfer bumps and waves in the sheathing. (The latter is more likely when re-paneling an older home.) Thicker trim pieces will also lay more accurately, so some homeowners and contractors opt for 29-gauge roof and wall panels with 26-gauge trim, a combination that is common and cost-effective.

 

When To Choose a Thinner Metal Roofing Gauge

Span isn’t always a concern in the residential market. Nearly all homes have a layer of plywood or oriented strand board sheathing covered by a weather-resistant barrier. The metal panels are affixed to the sheathing and serve no structural role in these instances; their job is to keep the sheathing dry. A quality 29-gauge panel is more than adequate for this—which is why it’s used on nearly 80 percent of homes with metal panels.

Despite this, thicker (lighter-gauge) panels can make sense for buildings in hail-prone areas, but not because of structural integrity. A 29-gauge metal panel can have the same impact-resistance rating from Underwriters’ Laboratory (UL) as a 26-gauge panel; the advantage of thicker metal panels in this case is that they are less prone to denting. If your customer lives in a place like Cheyenne, Wyoming (the hail capital of North America) and is concerned about long-term appearance, thicker panels may be the better option.
