Why Severe Hail Damage Matters For Building Owners & Roofers

Year in and year out, the world is experiencing an increase in extreme weather events. This makes it more important than ever to take measures to protect your building (or your customers’ building) from severe hail damage.

Why Does Hail Damage Matter?

Hail damage is becoming not only more frequent, but worse, on average, in each individual storm. Statistics and news reports regularly show that destruction from hail represents a larger threat every year (literally). One record-setting storm in South Texas in April of 2021 “dropped hail the size of grapefruits,” including this gargantuan stone over six inches in diameter:

Hail that size can be catastrophic for a structure that’s not properly prepared with a protective, hail-resistant roofing system. The building’s roof is its first and most important line of defense against severe weather — wind, rain, hail, snow, ice, and more — and especially for falling impact damage from severe hail.

A massive hail storm swept Calgary, Alberta on June 13, 2020, pummeling the city and nearby communities with tennis-ball-sized hail.  The damage was costly, with preliminary estimates weighing in at $1.2 billion (or more).  This well exceeded the $400 million in damage inflicted a decade earlier by the next-worst storm to hit the Calgary area. All told, the 2020 storm was the 4th costliest natural disaster ever to occur in Canada.

The bottom line is that severe hail damage matters, and your choice of roofing can make all the difference.

What Does Severe Hail Damage Do to a Roof?

This will depend, in part, on the size of the hail. Hail is the costliest weather hazard in Canada, causing extreme losses each year especially in the Calgary region and more generally across the Manitoba, Saskatchewan, and Alberta provinces, according to AIR:

FM Global, meanwhile, recognizes 3 zones in the U.S., categorized by the size of hail that’s familiar to that region over a 15-year “mean recurrence interval” (MRI):

  • GREEN: Moderate Hail — Size does not exceed 1.75-inch diameter for the MRI
  • ORANGE: Severe Hail — Size exceeds 1.75-inch diameter, but does not exceed 2-inch diameter for the MRI
  • RED: Very Severe Hail — Size exceeds 2-inch diameter for the MRI

Any structures in the orange and red zones are at greater risk of severe hail damage, which pummels glass, siding, and all vulnerable roofing materials (wood shake, asphalt, metal, and more). The lower the slope of the roof, the more vulnerable the structure and more important it will be to install a hail proof roofing system.

Severe hail damage to a roof could include:

  • Dents in shingles, shakes, and other materials
  • Cracking or splitting of wood shakes and shingles
  • Shattering of slate tiles
  • “Crazing” or round spidering patterns
  • Removal of tiny protective granules from asphalt shingles
  • Delamination and exposure of underlying systems

The largest hailstones can even threaten to put holes through weak areas of the roof and other catastrophic damage. Replacing or repairing a large commercial roof after a bad hailstorm can potentially cost hundreds of thousands of dollars. 

Severe Hail Damage Solutions

A reinforced roof design with appropriate roofing materials is especially important if your business operates within the severe or very severe hail zones of the US or Canada. Hail resistant qualities are a priority, but the roofing system should also provide weather protection from UV rays, severe wind, ice, snow, and all other weather-related hazards and conditions.

Conventional roofing materials, like wood, asphalt, metal, and slate, all come up short. A rubber roof made with premium virgin crumb rubber from recycled tires will repel even the largest hailstones without any damage while protecting a building for decades — with virtually no maintenance. All of this is possible with fast installs that save money, reduce waste and keep tires out of landfills.

Euroshield produces luxurous and nearly indestructible rubber roofing in natural slate or wood shake styles. Installers and building owners no longer need to sacrifice beauty and style for durability and hail resistance. Our roofing systems provide hail proof protection without the challenges, waste, or expense of other premium materials.
