Green roof construction permits.
Green roof initiative.
It may also include additional layers such as a root barrier and drainage and irrigation systems.
In november 2017 denver voters passed a green roof ordinance green roof initiative which required new and existing buildings over 25 000 square feet in size to install a green roof either as the building was constructed or when the roof was replaced for existing buildings.
Projects incorporating a green roof will receive a building permit for the green roof and a standard roof permit for the underlying roof waterproof membrane of the building.
This is a pivotal aspect of the initiative because the massive amount of development.
Denver s green roof initiative only requires a percentage of the available roof space to be used for a green roof or solar and the required percentage is based on your building s gross floor area.
You can choose to install the smallest solar system that meets the ordinance requirements but then you d be leaving money on the table.
The initiative provides for a corresponding increase in the percentage of green roof space in relation to the gross square footage of floor area within a building.
The green roof permit requires a denver licensed green roof installer.
A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane.
