Feasibility and professional design
A rooftop project begins with whether the building and roof can support the proposed use. The assessment may require structural information, existing drawings and evaluation of the intended occupancy and features. Planters, furniture and other additions should be disclosed rather than added after the design is set. Establish which professionals will assess capacity and document the design, and do not treat a surface installer’s material estimate as proof that the complete rooftop project is feasible.
