Guarding homes against the worst of Spring weather threats starts right at the top

As witnessed by recent events, the instability of spring weather can wreak havoc on a home. In many areas, tornadoes suddenly strike. In others, hailstorms cause costly damage. And in hurricane prone areas, it marks the beginning of the official season (the hurricane season began on June 1 and ends Nov. 30, 2022) with tropical storms already threatening.

While these monster weather events seem vastly different, they have plenty of commonalities. Each can bring powerfully strong winds, strong enough to rip a roof off a home. They also can result in severe damage, either by flying airborne debris or large objects striking and potentially penetrating a home, and intense, sudden downpours. In all cases, it’s the roof of a home that often bears the worst of these extreme conditions and must be relied upon to protect a home from even more costly and serious damage. 

“Spring brings a trifecta of threats, depending on the region where you live. Climate instability means it’s more important than ever to evaluate the resiliency of your home and make improvements with the potential of these damaging forces in mind,” said Renee Ramey, Metal Roofing Alliance (MRA) executive director.

Many roofers believe metal is the gold standard when it comes to roofing material to guard against severe weather events. That’s because when installed properly, quality metal roofs are rated to stand up to F2 tornado wind speeds (F-scale stands for the Fujita Scale of Tornado Intensity, with F2 equaling wind speeds of 113-157 mph), resist leaks and are much less likely to puncture, tear or crack due to flying debris or massive hailstones. 

Aside from choosing better performing and longer lasting materials, inform homeowners that their decisions about installers and materials can have an impact on how their roof performs in extreme weather events:

Pay Close Attention to Installation Practices

Install to protect against the worst of potential regional threats. That includes using quality weatherproof underlayment to further guard against water penetration and recommending the proper use of hurricane clips and interlocking systems that will help the home literally “batten down the hatches” in the event of an extreme storm. If the roof decking or sheathing isn’t structurally sound, the roofing materials or upgrades won’t matter; it must be stable from the start. 

Use Slope Design to An Advantage

More and varied roof slopes can improve the aerodynamics of a structure and reduce the pressure on a roof caused by high winds. For new construction or major remodeling projects, work with an architect and engineer on ways to better control and reduce the effects of strong wind force.

Make the Connection

Securing a roof to the walls decreases the potential of the roof flying off when it’s under intense pressure from high speed winds and severe air pressure fluctuations. During a tornado or hurricane, massive changes in air pressure caused by a penetration such as a broken window can blow a roof off. Securely attaching a roof to the walls helps prevent this phenomenon from occurring. Additionally, talk to the owner about whether to consider installing a movable flap next to the seam of the roof, which also can help stabilize air pressure.

Consider Style Practicality

In areas where hail damage is common, a textured metal roof design may help disguise potential dings that can result from heavy hail and flying debris. While a quality metal roof is designed to withstand blows and remain intact and impenetrable even when subjected to the heaviest of hailstorms, minor cosmetic imperfections resulting from impacts can be better disguised with textured vs. smooth styles. When it comes to impact damage, metal vastly outperforms traditional asphalt roofs, which can crack, dislodge and break, resulting in the need for premature replacement and increasing the risk of leaks and interior damage.
