Roofing systems, roofing systems with integrated solar racking systems, roofing system components, and related methods

A structural beam for use in a roofing system, the structural beam comprising:

• an extruded beam having a length, the extruded beam comprising a top wall and a bottom wall and two opposing side walls;
• one or more T-bolt slots in at least one of the side walls of the extruded beam of receiving accessory attachments;
• channel walls extending upward from the top wall of the extruded beam, the channel walls forming a threaded channel for securing a top cap to the extruded beam that extends the length of the extruded beam;
• and
• gasket channel walls extending upward from the top wall of the extruded beam, the gasket channel walls forming one or more gasket attachment channels for securing gaskets to the extruded beam.

A method of forming a roofing system, the method comprising:

• providing a plurality of structural beams, each of the structural beams comprising an extruded aluminum structural beam;
• providing roofing panels comprising at least one of an insulated roofing panel or a solar module;
• providing a plurality of top caps corresponding to the number of the structural beams, the top caps configured to secure the roofing panels in place on the structural beams;
• providing gaskets for sealing the roofing panels;
• securing the plurality of structural beams to a base structure;
• securing gaskets to the structural beams;
• securing gaskets to the top caps;
• positioning the roofing panels on the gaskets secured to the structural beams;
• placing the top caps in alignment with respective structural beams such that the gaskets secured to the top caps engage the roofing panels;
• securing the top caps to the respective structural beams such that the gaskets secured to the structural beams and the gaskets secured to the top caps sealably engage the roofing panels;
• and
• wherein one or more interior gutters built into each of the structural beams to drain any water that leaks between the gaskets and the roofing panels.
