Ventilation is defined by the U.S. Department of Energy as "the exchange of indoor and outdoor air." This sounds simple enough, but if your home's attic is not properly ventilated, excess heat and moisture cannot escape and can lead to a plethora of concerns for your home, your roof, and your wallet.

You can change the world by helping your neighbor, and the folks at JF Lopez Roofing are living proof. In partnership with the GAF Habitat for Humanity Contractor program, the company — based in Fond du Lac, Wisconsin — pledged what it calls the Legacy 100: the goal of installing 100 roofs on Habitat for Humanity homes over 10 years. With roof number 55 completed by the close of 2022 and more slated for 2023, these roofing heroes are already more than halfway there.

Think that your roof doesn't need protection against hail? Think again. Severe hail events are increasing in geographic footprint and are no longer just in hail alley. The geographic region that experiences 1 inch or larger hailstones has expanded to be nearly two-thirds of the United States. Nearly 10 percent more U.S. properties, more than 6.8 million, were affected by hail in 2021 than in 2020. Coinciding with the increase in properties affected by a damaging hail event in 2021, there was also an increase in insurance claims, which rose to $16.5 billion from $14.2 billion in 2020.

To get a firsthand account of what it's like to be a roofer, GAF spoke with Trenton Wisecup, president of Arrow Roofing Services in Michigan, and David Laurain, Arrow Roofing's vice president, to learn about their experiences in the roofing industry.
