Interlocking roofing panel system and method

A method of installing an interlocking panel system for covering a planar base surface comprising:

• securing a first panel to the planar base surface, the first panel comprising:
• a sheet-like section configured to cover a portion of the planar base surface, the sheet-like section having an outer face configured to face away from the planar base surface and an inner face configured to face toward the planar base surface;
• a receptacle located at an end of the first panel, the sheet-like section connected to and extending away from the receptacle, the receptacle having an opening proximate the inner face;
• a first projection extending toward the inner face;
• and
• a second projection extending away from the inner face;
• securing an interlock to the first panel by inserting an interlock hook portion into the receptacle of the first panel such that the interlock hook portion engages the first projection, the at least one of the interlock hook portion or the first projection preventing the interlock from being withdrawn from the first panel;
• securing the interlock to the planar base surface, the interlock comprising an interlock receiving portion;
• securing a second panel to the first panel by inserting a second panel hook portion into the interlock receiving portion between the first panel and the interlock such that the second panel hook portion engages the second projection and at least one of the second panel hook portion or the second projection deflect during the engagement therebetween, the at least one of the second panel hook portion or the second projection preventing the second panel from being withdrawn from the interlock receiving portion.

An interlocking panel system for covering a planar base surface comprising:

• a first panel comprising:
• a receptacle located at an end of the first panel;
• a planar section configured to cover a portion of the planar base surface, the planar section connected to and extending away from the receptacle, the planar face comprising:
• an inner face facing toward the planar base surface;
• and
• an outer face facing away from the planar base surface;
• a first projection facing the inner face;
• and
• a second projection facing the planar base surface;
• an interlock comprising a hook portion and a receiving portion, the hook portion configured to be inserted into the receptacle of the first panel, the at least one of the hook portion or the receptacle preventing the interlock from being withdrawn from the first panel;
• and
• a second panel comprising:
• a hook portion located at an end of the second panel;
• and
• a planar section configured to cover a portion of the planar base surface, the planar section connected to and extending away from the hook portion;
• wherein the hook portion is configured to be inserted into the receiving portion between the first panel and the interlock, the hook portion engaging with the second projection during insertion, with at least one of the hook portion or the second projection deflecting during the engagement therebetween, the at least one of the hook portion or the second projection preventing the second panel from being withdrawn from the first panel.
