Phoenix Metal Roofing Stands Strong Against Arizona’s Evolving Storm Patterns with New 2024 Impact Testing Standards

Arizona homeowners are witnessing an unprecedented shift in weather patterns, with hailstorms becoming increasingly frequent even in traditionally dry regions like Phoenix. Hailstorms are becoming increasingly frequent, even in areas like Phoenix that rarely saw such weather. This dramatic change has prompted the roofing industry to develop enhanced testing protocols and performance standards specifically designed to protect homes against these intensifying severe weather events.

The Rise of Severe Weather in the Valley

Recent weather data reveals a concerning trend for Phoenix residents. The Phoenix, AZ area has had 22 reports of on-the-ground hail by trained spotters, and has been under severe weather warnings 73 times during the past 12 months. While Phoenix, Arizona (population: 1445632) had 0 hail reports within 10 miles of the city center located at (33.44838, -112.07404) in 2024. The largest report of hail in 2024 near Phoenix was 0.00 inches, the broader Valley region has experienced significant storm activity, including events with quarter-sized hail possible in Sun City, Peoria, Glendale and Tolleson.

The National Weather Service documented multiple severe weather events throughout 2024, with October 15-16: Transition Event with Flash Flooding, Damaging Winds, Large Hail, and a Landspout Tornado being particularly notable for the Phoenix area. These changing weather patterns underscore the critical importance of having roofing systems that can withstand not just traditional desert conditions, but also the increasing threat of hail damage.

Understanding the New 2024 Metal Roofing Performance Standards

The roofing industry has responded to these evolving weather challenges with enhanced testing protocols and performance standards. For hail, roofs are subjected to UL 2218, which tests their protective capabilities and ranks them on a class system (from one to four). Metal roofs rank highest with a class four rating, which ensures the maximum protection from hail.

The UL 2218 testing standard represents the gold standard for hail impact resistance. Under Underwriters Laboratories (UL) Standard 2218, roofing materials are tested for impact resistance using steel ball testing. In this process: Steel balls of varying sizes, ranging from 1.25 inches (Class 1) to 2 inches (Class 4) in diameter, are dropped from heights of 12 to 20 feet onto roofing samples. Based on the results, materials are assigned a Class 1 to Class 4 rating, with Class 4 indicating the highest level of resistance to hail impact.

Additionally, the industry has incorporated more comprehensive testing approaches. The Factory Mutual (FM) 4473 test takes a different approach by using ice spheres instead of steel balls. The test is considered more realistic because it simulates the actual composition of hailstones. Ice balls are propelled at high speeds (using compressed air) to mimic the velocity of real hail.

Why Metal Roofing Excels in Arizona’s Climate

Metal roofing systems have emerged as the superior choice for Arizona homeowners seeking protection against severe weather. Metal roofing systems provide some of the highest ratings possible for fire, wind, rain, hail and impact protection. Metal roofs, whether galvanized steel, aluminum or copper, receive the highest class rating, Class A, according to UL 790 standards. Materials with a Class A fire rating have the lowest flame spread index and will not add fuel to a fire, making them ideal for wildfire-prone environments.

The performance advantages of metal roofing extend beyond just hail resistance. Metal roofing materials that achieve a Class 4 rating in this test are the most resistant to hail damage. This is the highest rating available and indicates that the roof can withstand significant impact without losing its structural integrity. Even when hail does make contact, Denting: This is usually a cosmetic issue. While dents might not look great, they don’t compromise the roof’s structural integrity.

For Phoenix homeowners, this translates to exceptional long-term value. Unlike asphalt shingles, which can suffer granule loss and premature aging, metal roofs maintain their integrity and functionality even after a hailstorm.

The Investment in Storm-Resistant Roofing

Storm damage resistance increases through proper installation and quality materials selection. Family safety improves with structurally sound roofing that withstands severe weather events.

The growing demand for resilient roofing solutions reflects homeowners’ increasing awareness of climate risks. MRA research demonstrates weather-related factors also are driving the interest in quality metal roof systems. When comparing the increase of climate-related disasters to the increase in homeowners choosing metal roof systems, MRA research indicates the demand for metal roofing has risen with the increase of climate-related disasters from 2015 to 2022. Metal roof systems have proved to be among the best options for regions that face hurricanes, high winds, hail and severe storm damage, heavy snow and ice and can earn a Class A fire classification (the highest rating possible for roof assemblies).

Looking Ahead: Preparing for Arizona’s Weather Future

As Arizona continues to experience evolving weather patterns, the importance of choosing roofing materials that can withstand both traditional desert conditions and emerging severe weather threats cannot be overstated. For homeowners in wildfire-, tornado- and hurricane-prone areas who have lived through devastating climate disasters, it makes sense to choose stronger, longer-lasting, more durable materials designed to better withstand extreme climatic events. Forward-thinking contractors recognize resilient building practices aren’t just a nice theory, and they are adjusting their offerings to address this major need ahead of the possibilities of more stringent building codes and insurance requirements.
