Madison Roofing: Article About Hail
Every so often, the region gets hit with a raucous hail storm that pelts homes with huge, damaging hail stones. Occasionally, those springtime hail stones surpass the size of a hockey puck, with one such 5.5 inch hail ball plummeting to the ground here in 2007. Even a smaller, one inch hail pellet can wreak significant damage to a home's roof.
Homeowners can take some steps, though, to ward off the frustrating damage caused by hail. If it's time for a new roof anyway, homeowners should talk with their experienced Madison roofing contractors about impact resistant roofing. Modern manufacturing makes roofs much more resilient to hail, offering polymers that beef up composition shingles and resins that make synthetic tile roofs stalwart throughout hail season. Other roof types, like stone coated steel, also provide some protection against hail, so homeowners have plenty of attractive options.
While shopping for an impact resistant roof, it also helps to know how impact resistance is classified. There are a couple of testing systems for roof impact resistance. Underwriter Laboratories' 2218 standard is used mostly for flexible roofing like asphalt shingles, and it tests whether the roof can withstand being hit twice with steel balls dropped onto the surface. FM Global's 4473 standard tests rigid roof coverings like tile and slate using ice stones that are forcefully shot at the roof.

In both cases, the most impact resistant roofs earn a Class 4 rating, demonstrating their ability to stand strong when struck with 2 inch stones. Class 3 impact resistant roofs offer slightly less durability, remaining intact when battered with stones measuring 1.75 inches in diameter. Class 1 and 2 roofs aren't considered suitable for hail prone areas.
For extra protection against hail damage, a trusted roofer may also install more durable underlayment and tongue in groove decking. Homeowners in hail susceptible regions might also consider structural changes like rebuilding the framework to create a steeper and, therefore, safer roof pitch.
Whether an impact resistant roof is in place or not, when a hail storm hits, homeowners should stay indoors. If a leak occurs during the storm, a bucket should be placed underneath, but homeowners should not go outside to investigate.
Once the storm passes, homeowners should have their roofs inspected by an experienced roofer who can assess the damage. It's common for hail to knock protective granules off asphalt shingles, creating a situation that allows the shingle to quickly deteriorate. Hail can also dent vents and flashing, rendering them ineffective and paving the way for future leaks.
