While many commercial solar installers boast of fully-ballasted systems that avoid rooftop penetrations, we have rarely seen successful rooftop solar systems without some positive attachment and anchoring to the structure. In many locations the rocks will need to be removed to allow for the solar array mounting system to make positive contact with the roof surface. If the rocks are not moved, they will be pushed into the membrane and provide locations for water settling and intrusion. The variety of rooftops found on commercial buildings can prove difficult for any rooftop solar engineer and contractor.
However, the membrane may be exposed to plant roots, animals and insects, and fertilizer chemicals. It is important that a protective barrier be used over the waterproofing membrane. With all components housed together, rooftop HVAC units can be easier for technicians to access. Maintenance and repairs may be made quicker with all parts in one location. Rooftop HVAC units are also called packaged units, as all components are packaged together in one cabinet. Inside the cabinet housing are all of the heating and/or cooling system components, depending on the type of system.
