Increasingly, owners of real estate are taking advantage of non-traditional sources of income generated by their properties. One such source is the licensing of space on the roof of a building. Although rooftop licensing is by no means new, the population of rooftop users is growing and diversifying.
Historically, rooftop use was limited to operators of radio and television transmission antennae. However, newer technologies such as solar and cellular have given rise to a variety of additional users of rooftop space.
