Denver is the latest US city to make green roofs compulsory | GBRI
 

Denver has become the latest US city to require new buildings to have green roofs- either rooftop gardens or solar installations.

The new mandate requires many existing buildings to be retrofitted with green roofs when the old roof wears out. Older buildings that cannot support the load of a green roof can get an exemption.

“These required building improvements would significantly reduce long term operating costs by lowering energy consumption and increasing the longevity of a roof,” the Denver Green Roof Initiative stated on its campaign website. “A green roof lasts 2-3 times as long as a traditional roof because the waterproofing membrane is protected from damage by the elements and workers by covering it with a growing medium and plants.”
