The Tennessee representative Rusty Grills says the lobbyist proposed a simple idea: repeal the state’s requirement for reflective roofs on many commercial buildings.

In late March, Grills and his fellow lawmakers voted to eliminate the rule, scrapping a measure meant to save energy, lower temperatures and protect Tennesseans from extreme heat.

It was another win for a well-organized lobbying campaign led by manufacturers of dark roofing materials.

Industry representatives called the rollback in Tennessee a needed correction as more of the state moved into a hotter climate zone, expanding the reach of the state’s cool-roof rule. Critics called it dangerous and “deceptive”.
