Vegetation-free zones are just that… areas of the roof where there
is no growing medium or plants – instead, the membrane is protected
by stone ballast or pavers.
• All borders, perimeters, and corners should be vegetative-free zones
• Be sure to provide a minimum 1 foot wide continuous vegetative free
zone around all rooftop equipment , penetrations, skylights, solar
panels, antenna supports, expansion joints, and interior parapet walls.
• Consider a vegetative-free zone where HVAC intake or exhaust could be
effected by plants or harm plants.
• Be sure to provide a minimum 3 foot wide continuous vegetative-
free zone around roof top structures such as mechanical rooms,
penthouses, and adjacent walls.
• Be sure to provide a minimum 3 foot wide vegetative-free zone to
partition the roof into sections no wider or longer than 125 feet.
Incorporate these breaks in the vegetation into expansion joints or roof
area dividers wherever possible.
• Must comply with local building and fire code requirements.
