Inverted seam roof covering system

A metal roof panel attachment system produces a finished roof surface presenting an overall smooth, planar configuration. Adjacent planar panels are attached to secondary support members which form a recessed joint incorporating a concealed drainage channel. Front and rear eave and rake sections are installed at the perimeter of the roof to form a finished, moisture-proof joint between the roof and walls. An outwardly extending flange directs water flow away from the walls of the structure.

I claim:

1. A roof covering system comprising:

a plurality of panels, each of said panels presenting four sides, with an opposed two of said sides each including a depending marginal member, adjacent ones of said panels presenting a joint area therebetween;

channel means configured for spanning said joint area below said marginal members in a joint spanning and draining relationship therewith for receiving any roof drainage matter passing through said joint area, preventing passage therethrough and for channeling said matter away from aid roof; and

retaining means for coupling said channel means with said adjacent ones of said panels in said joint spanning and draining relationship,

wherein each depending marginal member terminates in a plurality of tab structures for engagement by said retaining means for coupling said panels with said channel means, the other opposed two of said sides each including a lip member for mating engagement with a corresponding lip member of an adjacent one of said panels.

2. The roof covering system as set forth in claim 1, wherein each depending marginal member includes a tab structure extending longitudinally and said retaining means includes structure defining a tab receiving slot for receiving said tab structure therein, thereby coupling said panels with said channel means.

3. The roof covering system as set forth in claim 1 wherein said lip member is integrally formed as a part of said panels.

4. The roof covering system as set forth in claim 1, wherein said channel means comprises a member of generally U-shape including a pair of elongated opposed legs and said retaining means includes structure shaped for receiving said channel means.

5. A system for attaching metal roof panels having longitudinally and downwardly extending flanges presenting tab structures to an underlying roof structure comprising:

a plurality of elongated channel members disposed in side-by-side relationship on said roof structure, each of said channel members having a pair of opposed longitudinally upstanding flange portions;

a plurality of elongated retaining members for mounting in covering relationship to said channel members for securing said channel members to said underlying roof structure, said retaining members including structure defining a pair of parallel spaced longitudinally extending grooves for receiving said channel flange portions,

said structure including longitudinally spaced tab receiving slots disposed between said grooves for mating engagement with said tab structures for securement of said roof panels.

6. A covering system comprising:

a plurality of panels, each presenting a depending marginal member, adjacent ones of said panels presenting a joint area therebetween;

channel means configured for spanning said joint area below said marginal members in a joint spanning and draining relationship therewith for receiving any drainage matter passing through said joint area, preventing passage therethrough and for channeling said matter away from said joint area; and

retaining means for coupling said channel means with said adjacent ones of said panels in said joint spanning and draining relationship,

wherein one of said marginal member and retaining means includes a tab and the other of said marginal member and retaining means including structure defining a tab receiving slot for coupling said channel means with said panel.

7. A covering system comprising:

a plurality of covering panels each presenting a pair of opposed, depending marginal members;

a drainage channel; and

retaining means for coupling one of said marginal members of one of said panels in a side-by-side relationship with one of said marginal members of another one of said panels thereby forming a joint area between said side-by-side marginal members,

said drainage channel including structure for spanning said joint area below said marginal members,

said retaining means including means for coupling said drainage channel in a spanning relationship with said joint area below said marginal members for receiving any drainage matter passing through said joint area and for channeling said drainage matter away from said joint area,

one of said marginal members and retaining means including a tab and the other of said marginal members and retaining means including a tab-receiving slot for receiving said tab for coupling said marginal members in said side-by-side relationship.

8. The system as set forth in claim 7, said panels including roof covering panels.

9. The system as set forth in claim 7, said panels being composed of sheet metal.

10. The system as set forth in claim 7, said drainage channel presenting a generally U-shaped configuration having a pair of opposed, upstanding legs, said retaining means including means for coupling said channel in a spanning relationship with said joint area with a portion of said side-by-side marginal members between said upstanding legs.

11. The system as set forth in claim 7, each of said marginal members each including a plurality of said tabs, said retaining means including a corresponding plurality of said tab-receiving slots.

12. The system as set forth in claim 11, said tabs being integral with said marginal members.

13. The system as set forth in claim 7, said retaining means including means for coupling with a surface to be covered by said covering system and with said channel between said retaining means and the surface.

14. The system as set forth in claim 7, said panels each including a planar portion between said marginal members thereof, said retaining means including means for coupling said marginal members and thereby the associated panels thereof so that the planar portion of each of said panels lie in the same plane.
