The GAF Cool Community Project combats the urban heat island
Buildings are designed to keep the outside weather out and the inside space conditioned as the occupants desire. A building's enclosure or envelope is made up of multiple layers of materials with the goal of stopping the uncontrolled movement of water, air, heat, and moisture vapor.
Work is getting underway in Greater Charlotte, North Carolina, as GAF supports Habitat for Humanity with the 2023 Jimmy and Rosalynn Carter Work Project. The five-day build event began in 1984 when former President Jimmy Carter and former first lady Rosalyn Carter led a group of Habitat for Humanity volunteers to New York, building alongside 19 families in need of safe, affordable housing. For 36 years, the Carters have worked side by side with professional builders and volunteers at locations around the world to build and raise awareness of affordable housing.

You can also benefit by knowing when you need roof ventilation or drip edging, when to consider insulation, and how to calculate roof materials costs. Here are the key details to understand.

One of the trickier questions—because there isn't a definitive answer—is: "Can you put new shingles over old shingles?" The answer to this will depend on certain factors, and you can only provide a firm "yes" or "no" after inspecting an individual's roof.
