High-Performance Protection

Delivering a weather-resistant structure requires a comprehensive approach to building design. This includes careful consideration of the building materials and systems used on the project. For example, roofing systems can be called on to provide high-performance protection. To solve this challenge we turn to metal roofing systems, not only are these systems resilient to a wide range of extreme weather conditions, but they also are available in a myriad of colors and profile options to meet nearly any design vision.
A building's ability to withstand today's increasingly severe and frequent weather events depends on its roofing system. Roofs protect against rain, hail, snow, high winds and even flaming debris from forest or brush fires. They can also be called on to support a building's ability to maintain a comfortable interior environment, so protection from heat and the sun is also crucial. High-quality metal substrates and polyvinylidene fluoride (PVDF) paint finishes provide enhanced weather resistance.
Starting with the substrate, most metal roofing panels achieve a class A fire rating, which represents the highest rating possible. As a result, they can provide superior resistance to flaming debris from forest fires, brush fires, or a nearby lightning strike. Furthermore, given metal roofing panels' substantial strength-to-weight ratio and their ability to interlock via a snap or mechanically locked system, they can resist damage from high wind speeds, including HVHZ (high-velocity hurricane zone) requirements in southern Florida. When installed per manufacturer's installation instructions and using complete assemblies, the metal roofing system can receive class 90 UL 580 wind uplift ratings and meet UL 1897 extended phase wind uplift requirements.
Finally, metal has a high thermal emittance rate, which means it sheds heat quickly to reduce the number of peak operating hours for a building's HVAC systems. Coupled with cool-roof-rated PVDF finishes, metal roofing panels provide enhanced protection against solar heat gain. Likewise, PVDF offers protection against sun-induced fading for a roofing solution that can last up to three times longer than a conventional system.
It is important to consider the manufacturer of the metal roofing system. Select manufacturers can offer several types of warranties to give peace of mind to both roofing professionals and end-users.
Something to consider for your home or building. Thank you, Brian McLaughlin, for this input.
