Retrofit Roof System and a Clip Therefor

Abstract

A roofing system for retrofitting an installed roof with a new roof and a coupling member, or clip, therefor. In some embodiments, the clip includes a housing adapted for slideable engagement with a subframe coupled to an installed roof panel and a rail adapted to couple with a new roof panel. The housing has a slot extending therethrough. The rail extends through the slot and is slideable relative to the housing within the slot.

1 . A clip for coupling a new roof panel to an installed roof panel, the clip comprising:
 a housing adapted for slideable engagement with a subframe coupled to the installed roof panel, the housing having slot extending therethrough; and   a rail extending through the slot of the housing and adapted to couple with the new roof panel;   wherein the rail is slideable relative to the housing.   
     
     
         2 . The clip of  claim 1 , wherein the housing further comprises a top having the slot extending therethrough and two opposing ends, each end extending from the top and having a punch out extending therethrough, and wherein the rail extends through both of the punch outs. 
     
     
         3 . The clip of  claim 2 , wherein the housing further comprises a bottom extending substantially parallel to the top and spatially offset therefrom, the bottom having a flange extending therefrom and configured to be slideably received within the subframe. 
     
     
         4 . The clip of  claim 1 , wherein the housing further comprises a top and two opposing sides, each side extending from the top and having a first portion substantially normal to the top and a second portion extending at an acute angle from the first portion toward the top. 
     
     
         5 . The clip of  claim 1 , wherein the slot is disposed in a top of the housing and wherein the rail comprises a first portion and a second portion connected to the first portion, wherein first portion has a width measured in a direction parallel to the top exceeding a width of the slot and the second portion extends through the slot. 
     
     
         6 . The clip of  claim 5 , wherein the rail further comprises a flanged portion extending normally from the second portion, the flanged portion configured to couple with the new roof panel. 
     
     
         7 . A roof system comprising:
 a roof panel installed on a building;   a subframe coupled to the roof panel; and   a coupling member slideably interlocked with the subframe.   
     
     
         8 . The roof system of  claim 7 , wherein the coupling member comprises a housing moveable relative the subframe in a direction substantially parallel to a longitudinal axis of the housing. 
     
     
         9 . The roof system of  claim 8 , wherein the housing comprises two opposing sides, each side having an angled portion, and wherein the subframe is disposed between each angled portion and a bottom of the housing, whereby the coupling member and the subframe are interlocked. 
     
     
         10 . The roof system of  claim 8 , wherein the housing comprises two opposing ends, each end having a punch out extending therethrough. 
     
     
         11 . The roof system of  claim 10 , wherein the coupling member further comprises a rail extending through both punch outs and slideable relative to the housing. 
     
     
         12 . The roof system of  claim 11 , wherein the housing further comprises a top extending between the two ends and having a slot extending therethrough, the slot connected to both of the punch outs and wherein the rail extends through the slot. 
     
     
         13 . A roof system comprising:
 a subframe;   a coupling member slideably interlocked with the subframe; and   a roof panel supported by the coupling member.   
     
     
         14 . The roof system of  claim 13 , wherein the coupling member comprises a rail having a flanged portion coupled to the roof panel. 
     
     
         15 . The roof system of  claim 14 , wherein the coupling member further comprises a housing having a top with a slot extending therethrough and wherein the rail extends through the slot and is moveable relative to the housing. 
     
     
         16 . The roof system of  claim 13 , wherein the coupling member comprises a housing moveable relative the subframe in a direction substantially parallel to a longitudinal axis of the subframe. 
     
     
         17 . The roof system of  claim 16 , wherein the housing comprises two opposing sides, each side having an angled portion, and wherein the subframe is inserted between each angled portion and a bottom of the housing, whereby the coupling member and the subframe are interlocked. 
     
     
         18 . The roof system of  claim 16 , wherein the housing comprises two opposing ends, each end having a punch out extending therethrough. 
     
     
         19 . The roof system of  claim 18 , wherein the coupling member further comprises a rail extending through both punch outs and slideable relative to the housing. 
     
     
         20 . The roof system of  claim 13 , wherein the coupling member comprises a housing slideably interlocked with the subframe and a rail slideably interlocked with the housing. 
     
     
         21 . The roof system of  claim 20 , further comprising a second roof panel coupled to the subframe. 
     
     
         22 . The roof system of  claim 21 , further comprising a gap disposed between the roof panels. 
     
     
         23 . The roof system of  claim 22 , further comprising a support panel disposed in the gap and supported by the subframe. 
     
     
         24 . The roof system of  claim 22 , further comprising insulation disposed in the gap.
