In late March, the Sun crosses the equator and begins to move into the Northern Hemisphere. (We know that the Sun is stationary and Earth is moving, but it is easier to think about it the other way around.) Temperatures rise, perennials bloom, and we’re glad that winter is over. It’s a great time of year. The heavy coats go back into the closet and everyone’s attitude brightens. But we all know those warmer spring temperatures will eventually turn downright hot in summer. Some say it’s getting even hotter due to global warming. A prepainted product is on the market that can help mitigate environmental concerns raised by increasing temperatures. It’s called cool roofing and it continues to rise in popularity.
